skin cancer on dogs |

What to look for: Since there are so many kinds of allergies dogs can have (from food to flea/tick bites and a wide range of other possibilities), it’s important to look for any change in behavior when exposed to something new. If your dog goes a few days showing lack of energy, has a consistent cough or sneeze, or if anything else seems out-of-place, you might be dealing with allergies.
Babesiosis* is spread by members of the family Ixodidae, or hard ticks. The two species of the genus Babesia that affect dogs are B. canis and B. gibsoni. Babesiosis can cause hemolytic anemia in dogs.[28]

Ear infections are common in dogs, particularly breeds with hanging ears, such as Beagles, and dogs with narrow ear canals, such as Cocker Spaniels. Other predisposing factors include allergies, ear parasites, and hypothyroidism.[74]
Because of the overpopulation of dogs in some countries, puppies born to strays or as the result of accidental breedings often end up being killed in animal shelters. Spaying and neutering can also decrease the risk of hormone-driven diseases such as mammary cancer, as well as undesired hormone-driven behaviors. However, certain medical problems are more likely after neutering, such as urinary incontinence in females[71] and prostate cancer in males.[72] The hormonal changes involved with sterilization are likely to somewhat change the animal’s personality, however, and some object to spaying and neutering as the sterilization could be carried out without the excision of organs.
Lick granuloma also known as acral lick dermatitis, is a skin disorder in dogs resulting from an urge to lick the lower portion of the leg. The lesion from the incessant licking is a thickened, firm, oval plaque.[34]
Horner’s syndrome* results from damage to the sympathetic innervation of the eye. Signs include enophthalmos (sunken eye), miosis (small pupil), elevated third eyelid, and ptosis (drooping of the upper eyelid). Usually the syndrome in dogs is idiopathic, but it can also be caused by trauma, tumors, or ear infections.[71]
Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10%). Typical signs in dogs include hair loss and scaly skin.[21]
Kanye West’s Adidas Yeezy shoe designs are typically met with Air Jordan-level fanfare when they’re released, but fans are accusing the rapper of phoning it in with his most recent design, which some say resembles Crocs.
6. Rabies: Rabies is the disease made famous in the hearbreaking scene in Old Yeller. Thankfully, the widespread use of the rabies vaccine in recent years has made its occurrence in pets in the U.S. quite rare. However, it is still present in wild animal populations, and because rabies is always fatal, it’s critical to make sure that your pets are current on their rabies vaccination.
2. Heartworm: Heartworm is a disease spread by mosquitoes and it has been diagnosed in all 50 states. While it is much more common in dogs, cats can also acquire the disease. If the infection is caught early enough in dogs, it can generally be treated, but there is no cure for feline heartworm disease. Therefore, the best way to keep your pets heart free of potentially deadly worms, is through a monthly preventative, prescribed by your veterinarian.

Heartworm is easily preventable with an inexpensive, chewable pill or topical medication available as a vet’s prescription. The pills or topical are usually administered monthly and can be given to dogs under 6 months of age without a blood test. Older animals must be screened for the disease prior to starting medication.

Subvalvular aortic stenosis (Subaortic stenosis; SAS) is a congenital disease in dogs characterized by left ventricular outflow tract obstruction by a discrete ring or tunnel of fibrous tissue immediately below the aortic valve. It is inherited in Newfoundlands, and also found in Golden Retrievers, Rottweilers, Boxers, Bulldogs, German Shepherds, and Samoyeds. Signs include a left basilar systolic heart murmur, weak femoral pulse, fainting and exercise intolerance. Dogs with severe SAS are predisposed to dying suddenly.[49]
If your veterinarian has diagnosed your dog with ringworm, he or she will explain what you must do to prevent the fungus from spreading to your other pets—and to the human members of the household. But keep in mind that if you have other pets, it’s likely that most of them have been exposed as well. Your veterinarian may recommend that you do the following:
Feeding table scraps to a dog is generally not recommended, at least in excess. Just as in humans, a dog’s diet must consist of the appropriate mix of nutrients, carbohydrates, and proteins in order to give them the minerals and vitamins that they need. Dogs get ample correct nutrition from their natural, normal diet; wild and feral dogs can usually get all the nutrients needed from a diet of whole prey and raw meat. In addition, a human diet is not ideal for a dog: the concept of a “balanced” diet for a facultative carnivore like a dog is not the same as in an omnivorous human. Dogs will usually eat all the scraps and treats they are fed: usually too much food. While not all human delicacies are acutely toxic to dogs (see above), many have the same chronically unfortunate results as they do for humans.

Pasteurellosis is a bacterial disease associated with animal bites and scratches. Pasteurella is a normal bacterium that lives in the mouths of healthy dogs. The bacteria do not typically make dogs sick; however, dogs can develop abscesses or skin infections in places where they were scratched or bitten by another animal.

Garlic & Onions* are toxic to dogs. Onions, Garlic, Chives – can cause the destruction of red blood cells known as Heinz body anemia, a form of hemolytic anemia. No clear quantity has been established as to the onset of the anemia. But for garlic, if your dog consumes the equivalent of 1 teaspoon of garlic for every 10 pounds of their weight (1 teaspoon for a 10-pound dog) it can destroy red blood cells. Poisonous reaction can result from raw, cooked or dried onions, garlic, chives, including those included in powdered or dehydrated forms. Avoid all foods that contain onions or onion variants (such as spaghetti sauce).
There are no specific steps you can take to prevent your dog from contracting the disease, but there is some evidence of seasonal fluctuation, with most cases appearing between November and June. New advice suggests keeping your dog away from very muddy areas. 
Lymphangiectasia is an intestinal disease of dogs characterized by chronic diarrhea and loss of proteins such as serum albumin and globulin. It is considered to be a chronic form of protein-losing enteropathy. Breeds commonly affected include the Soft-Coated Wheaten Terrier, Norwegian Lundehund, Basenji, and Yorkshire Terrier.[6]
Bladder stones or uroliths are common in dogs. The stones form in the urinary bladder in varying size and numbers secondary to infection, dietary influences, and genetics. Types of stones include struvite, calcium oxalate, urate, cystine, calcium phosphate, and silicate. Struvite and calcium oxalate stones are by far the most common.[6]
Some dogs have food allergies just as humans do; this is particular to the individual dog and not characteristic of the species as a whole. An example is a dog becoming physically ill from salmon; many humans likewise have seafood allergies.
Prostate disease* in dogs includes benign prostatic hyperplasia (BPH), prostatitis (infection of the prostate), cancer, and cysts and abscesses. BPH is the most common and is found in older intact (not neutered) dogs. Signs include blood in the urine and straining to urinate and defecate. Castration is the treatment of choice.[157] Prostatis can be associated with BPH. Bacteria causing prostatitis include E. coli, Staphylococcus spp., Streptococcus spp., and Mycoplasma spp.[158]

Salmonella spreads to people through contaminated food (eggs and meat) or contact with stool of certain animals including dogs. Salmonella infections have been linked to some brands of dry dog food, treats, and chew toys like pig ears and to “raw food” diets for dogs. While it usually doesn’t make the dogs sick, Salmonella can cause serious illness when it is passed to people.

Female cats and dogs are seven times more likely to develop mammary tumors if they are not spayed before their first heat cycle.[73] The high dietary estrogen content of the average commercial pet food may be contributing factors in the development of mammary cancer, especially when these exogenous sources are added to those normal estrogens produced by the body. Dog food containing soybeans or soybean fractions have been found to contain phytoestrogens in levels that could have biological effects when ingested longterm.[74]
Keeping your dog away from tick-prone areas and checking your dog for ticks are always good ideas, but preventative tick medicines are the most effective way to prevent Lyme disease, and other tick-borne illnesses.
Uveitis* is inflammation within the eye. Anterior uveitis (inflammation of the iris and ciliary body) is most common in dogs. The disease is usually immune-mediated in dogs, but may also be caused by trauma, cataracts, infectious canine hepatitis, leptospirosis, ehrlichiosis, or systemic fungal infections.[73]
Onions cause hemolytic anemia in dogs (and cats).[44] Allyl propyl disulfide has been reported as being considered to be the main cause of onion poisoning in dogs.[44] Thiosulfate has also been reported as being implicated. Thiosulfate levels are not affected by cooking or processing. Occasional exposure to small amounts is usually not a problem, but continuous exposure to even small amounts can be a serious threat. Also garlic contains thiosulfate, even if to a significantly lesser extent, and it is also known to cause diarrhea and vomiting.
With two rescue dogs brought to Canada being diagnosed with what are believed to be the country’s first cases of dog flu, dog owners are being warned to keep an eye out for the highly contagious virus.

Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs involving the retina, choroid, and sclera. It can be a mild disease or cause blindness. It is known to occur in Smooth and Rough Collies, Shetland Sheepdogs, Australian Shepherds, Border Collies, and Nova Scotia Duck Tolling Retrievers.[62]
Hypertrophic osteodystrophy is a bone disease in rapidly growing large breed dogs. Signs include swelling of the metaphysis (the part of the bone adjacent to the joint), pain, depression, loss of appetite, and fever. The disease is usually bilateral in the limb bones.[41]
If your dog will be housed outside, provide shelter such as a doghouse for when it is cold or rainy and shade for when it is hot. Protecting your dog from the changes in weather will reduce stress and help keep it healthy.
Blastomycosis is another very serious fungal disease that affects dogs near the Great Lakes region and other Eastern U.S. river basins. The fungus lives in soil sheltered from the sun, mainly along riverbanks, lakes, and swamps. Most dogs who get it live within 400 meters of a body of water. Large breed male dogs are most at risk and symptoms typically include difficulty breathing, skin lesions, and loss of appetite.

Unfortunately, kidney disease that develops over a pet’s lifetime—a.k.a. chronic kidney disease—is not preventable most of the time. Dogs with a genetic predisposition to kidney failure are most at risk.
Aspergillosis* is a fungal disease that in dogs is caused primarily by Aspergillus fumigatus. Infection is usually in the nasal cavity. Typical signs in dogs include sneezing, nasal discharge, bleeding from the nose, and ulcerations of the nose.[23]
Hereditary orthopedic diseases are mainly found in purebred dogs. Hip dysplasia is a common problem that primarily affects larger breeds. Hip dysplasia is a defect in the shape of the hip joint which can, depending on the degree of hip luxation, be quite painful to the dog as it ages. Over time it often causes arthritis in the hips. Dysplasia can also occur in the elbow joint. Luxating patellas can be a problem for smaller breeds. It can cause lameness and pain in the hind legs.
If your veterinarian has diagnosed your dog with ringworm, he or she will explain what you must do to prevent the fungus from spreading to your other pets—and to the human members of the household. But keep in mind that if you have other pets, it’s likely that most of them have been exposed as well. Your veterinarian may recommend that you do the following:
If your dog becomes sick or dies soon after purchase or adoption, take your dog to the veterinarian promptly, and inform the pet store, breeder, or rescue organization about the pet’s illness or death. Make sure to tell your veterinarian if the pet was adopted internationally. Thoroughly clean the area occupied by your pet, and consider waiting at least a few weeks before purchasing or adopting another pet.
Acromegaly (also known as hypersomatotropism) is a hormonal condition resulting from over-secretion of the growth hormone somatotropin[128] from the pituitary gland.[129] The hormone is responsible for growth from birth to adulthood. Normally in adulthood, the growth plates of the bones close and the secretion of the hormone slows considerably. Because the bone plates close when entering maturity, the continued growth of acromegaly is not of normal proportions.[130] Most dogs with the disease are unspayed females, but the condition can come about with use of medications containing progesterone.[130][131][132][133][134] Acromegaly patients often also have diabetes mellitus.[135][136] There is a transient form of acromegaly which can affect females at the diestrus portion of the reproductive cycle.[124] This condition is brought about by the mammary glands[137] excreting excess growth hormone, which is triggered by progesterone from the ovaries. As with non-transient acromegaly, spaying is necessary.[135] The symptoms can include overgrowth or enlargement of gums with wide spaces between teeth,[130] increased drinking, increased urination, thickening of the skin and skin folds, enlargement of the tongue and excessive panting.[138] Acromegaly is also possible from a somatotroph adenoma.[138] The hormone somatostatin can also be useful in treatment.[139] Since hypothyroidism is connected with the release of excess growth hormone, hypothyroidism can be mistaken for acromegaly.[140]
Nasal cancer makes up one to two percent of all types of tumors in dogs. Adenocarcinoma is the most common type, followed by sarcomas such as fiborsarcoma and chondrosarcoma. Signs include sneezing and bloody nasal discharge.[161]

Genetic conditions are a problem in some dogs, particularly purebreeds. For this reason many of the national kennel clubs require that dogs with certain genetic illnesses or who are deemed to be carriers cannot be registered. Some of the most common conditions include hip dysplasia, seen in large breed dogs, von Willebrand disease, a disease that affects platelets that is inherited in Doberman Pinschers, entropion, a curling in of the eyelid seen in Shar Peis and many other breeds, progressive retinal atrophy, inherited in many breeds, deafness, and epilepsy, known to be inherited in Belgian Shepherd Dogs, German Shepherd Dogs, Cocker Spaniels, and St. Bernards.[14]
Ringworm is a fungal skin disease that in dogs is caused by Microsporum canis (70%), Microsporum gypseum (20%), and Trichophyton mentagrophytes (10%). Typical signs in dogs include hair loss and scaly skin.[21]
“The cause of Alabama Rot, clinically known as idiopathic cutaneous and renal glomerular vasculopathy (CRGV), is still unknown and there is no known way to prevent a dog from contracting the disease,” said David Walker, from Anderson Moores.
Mouse and rat poisons containing cholecalciferol cause hypercalcemia and hyperphosphatemia in dogs. Clinical signs include depression, loss of appetite, vomiting blood, weakness, and shock. Treatment is as above for recent exposure. When hypercalcemia occurs (which can take 1 to 2 weeks), treatment is with intravenous fluids (saline), diuretics, corticosteroids, and calcitonin. Long term prognosis is good once the dog is stabilized.
Retinal detachment* is caused in dogs by genetic disorders such as retinal dysplasia or Collie eye anomaly, trauma, inflammation or cancer. Reattachment may occur spontaneously or with medical or surgical therapy.[68]
People exposed to Salmonella might have diarrhea, vomiting, fever, or abdominal cramps. Infants, elderly persons, and those with weakened immune systems are more likely than others to develop severe illness.
Granulomatous meningoencephalitis (GME) (including Pug Dog encephalitis and other noninfectious causes of meningoencephalitis) is an inflammatory disease of the central nervous system of dogs. It is a form of meningoencephalitis. The disease is more common in female toy dogs of young and middle age.
What to look for: Since there are so many kinds of allergies dogs can have (from food to flea/tick bites and a wide range of other possibilities), it’s important to look for any change in behavior when exposed to something new. If your dog goes a few days showing lack of energy, has a consistent cough or sneeze, or if anything else seems out-of-place, you might be dealing with allergies.
Eye diseases are common in dogs. Cataracts, canine glaucoma, and entropion are seen in dogs. Canine-specific eye diseases include progressive retinal atrophy, Collie eye anomaly, sudden acquired retinal degeneration, and cherry eye. Injury to the eye can result in corneal ulcers.

Overdoses of vitamins can be harmful in dogs. As an example, calcium in excess can cause bone problems, especially in the large-breed dogs. Over-supplementation of vitamins A and D can cause vitamin toxicity in dogs.[68] Excess vitamin A can cause dehydration, joint pain and can also harm the blood vessels, while too much vitamin D can cause muscular atrophy, or loss of appetite.
One of the most common fungal diseases in dogs is ringworm, or dermatophytosis, an infection of the skin, hair, or nails. There are three fungal species that cause ringworm in dogs. About 70 percent of infections are caused by Microsporum canis, 20 percent by M. gypseum, and 10 percent by Trichophyton mentagrophytes. Signs include hair loss and scaling of the skin. Treatment for localized ringworm is not always necessary as the disease is self-limiting, but the cliinical course can be shortened by using topical miconazole or clotrimazole. Generalized infections, most commonly seen in immunocompromised dogs, can be treated with oral antifungal drugs such as griseofulvin or itraconazole. Infection can spread to humans.[9]

Megaesophagus is a disease of the esophagus characterized by low motility and dilation. Most cases in adult dogs are idiopathic. It is the most common cause of regurgitation in dogs. Other causes of megaesophagus include myasthenia gravis, lead poisoning, and Addison’s disease.[141]
Pica in dogs may be a sign of Immune-mediated hemolytic anemia, especially when it involves eating substances such as tile grout, concrete dust, and sand. Dogs exhibiting this form of pica should be tested for anemia with a Complete blood count including Hematocrit levels, or Packed cell volume.[46][47]

You need a heads-up on potential health problems and their risk factors, so you can prevent them altogether. Well, here it is: the most common yet preventable dog diseases, along with expert advice from California veterinarian Dr. Nicole Eckholm of the Pet Emergency and Specialty Center of Marin.
“If you live in a heartworm endemic area, which is an area with mosquitoes, heartworm prevention is a must,” Dr. Eckholm says. “There are parts of the country where mosquitoes aren’t prevalent and therefore heartworm prevention isn’t used as frequently.”
Tapeworms, roundworms, hookworms, and whipworms are common internal parasites in dogs. And although any worm infestation can make your pooch uncomfortable, some, like hookworms, can be fatal in puppies. Signs your dog may have worms include:
Perianal gland tumor (also called hepatoid tumor) is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum. They are most common in intact (not neutered) male dogs.[161]
Discoid lupus erythematosus is an uncommon autoimmune disease of the skin in dogs. It does not progress to systemic lupus erythematosus in dogs. The most common initial symptom is scaling and loss of pigment on the nose.[34]

Pasteurella is found in 50% of patients with infected dog bite wounds. Pasteurella can cause painful wound and skin infections. In more severe cases, it can cause widespread infection and might even affect the nervous system.
Canine parvovirus is caused by infection with CPV, most often, CPV-2a or CPV-2b. All dogs are at risk for developing canine parvovirus. Puppies less than 4 months old and dogs that have not been vaccinated against the virus are at increased risk for infection.

Squamous cell carcinoma* is a malignant tumor in dogs that most commonly occurs in the oral cavity, including the tongue, tonsils, and gingiva. Squamous cell carcinoma accounts for 5 percent of skin tumors in dogs, and are the most common tumor of the toe. Dogs with unpigmented skin on the nose may develop this cancer from long-term sun exposure.[161]

Deafness* in dogs can be either acquired or congenital. Predisposing factors for acquired deafness include chronic infection, use of certain drugs, and most commonly, age-related changes in the cochlea. Congenital deafness can be genetic, seen sometimes in dogs with merle or white coats, or caused by in utero damage from infections or toxins.[75]

Some diseases and other health problems are common to both humans and dogs; others are unique to dogs and other animals. Dogs are susceptible to various diseases; similarly to humans, they can have diabetes, epilepsy, cancer, or arthritis.
Macadamia nuts can cause non-fatal stiffness, tremors, hyperthermia, and abdominal pain.[48] The exact mechanism is not known. Most dogs recover with supportive care when the source of exposure is removed.
Rabies is a viral disease that may affect the brain and spinal cord of all mammals, including cats, dogs and humans. This preventable disease has been reported in every state except Hawaii. There’s good reason that the very word “rabies” evokes fear in people—once symptoms appear, rabies is close to 100% fatal.
Diagnosis of canine parvovirus is based on symptoms, physical examination, and laboratory tests. In puppies and dogs that have not been vaccinated, CPV infection often is suspected when bloody diarrhea, loss of appetite, and vomiting develop suddenly. Physical examination may reveal signs of dehydration (e.g., lethargy, sunken eyes, dry gums, rapid heart rate, concentrated urine), fever, abdominal discomfort, swollen lymph nodes, and weight loss.
9. Diabetes: Just like with humans, pets can develop diabetes as part of the aging process. While diabetes in cats and dogs can often be controlled by a plan of diet and exercise, some pets will require regular insulin shots.
Food allergy* in dogs is commonly manifested as itching, especially of the face, paws, and the underside. Skin testing has proved unreliable, and a trial of a hypoallergenic diet is usually used for diagnosis.[80]
Luxating patella is a medial or lateral displacement of the patella, or kneecap. It is strongly suspected to be inherited, but can also result from trauma.[36] It is more common in smaller breeds of dogs [1]
Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs involving the retina, choroid, and sclera. It can be a mild disease or cause blindness. It is known to occur in Smooth and Rough Collies, Shetland Sheepdogs, Australian Shepherds, Border Collies, and Nova Scotia Duck Tolling Retrievers.[62]
So keep those chompers clean! Brush regularly throughout your dog’s lifetime—meaning at least once a week—offer bully sticks or other hard chew toys to remove plaque, or get a professional teeth cleaning done at your vet’s office, which requires anesthesia but is quite effective.
Every year when you bring your pet in for a check-up, your veterinarian likely talks to you about vaccines and gives Fluffy or Fido a good look over. They may draw blood, or recommend preventative care routines, like a dental cleaning or grooming. But what are some of the most common serious ailments for cats and dogs that your veterinarian wants to help you prevent and control?
Heartworm is a parasitic worm that lives in the heart and pulmonary arteries of an infected animal. The worms travel through the bloodstream—harming arteries and vital organs as they go—ultimately completing their journey to the vessels of the lung and the heart chamber about six months after the initial infection. Several hundred worms can live in one dog for five to seven years.

Congestive heart failure* is the result of any severe, overwhelming heart disease that most commonly results in pulmonary edema (fluid in the lungs), pleural effusion (fluid around the lungs), and/or ascites (fluid in the abdomen). It can be caused by the above two diseases, congenital heart defects such as patent ductus arteriosus, pulmonary hypertension, heartworm (Dirofilaria immitis) disease, or pericardial effusion. Signs depend on which side of the heart is affected. Left-sided heart failure results in rapid and/or difficulty breathing and sometimes coughing from a build-up of fluid in the lungs (pulmonary edema). Right-sided heart failure results in a large liver (congestion) and build-up of fluid in the abdomen (ascites), uncommonly fluid around the lungs (pleural effusion), or, rarely, peripheral edema.[51]

Melanomas* account for four to six percent of skin tumors in dogs and are usually benign. They are the second most common tumor of the toe and are malignant in this location. Malignant melanoma is also a common oral tumor in dogs. Malignant tumors most commonly spread to the lymph nodes and lungs.[161]
Toxocara roundworms cause a parasitic disease known as toxocariasis. Dogs and people can become infected by accidentally swallowing roundworm eggs from the environment. In addition, larval worms can cross through the placenta, milk, or colostrum of a mother dog, passing the infection to her puppies. Infected puppies usually do not develop and grow well and might have a pot-bellied appearance.
Pemphigus is an uncommon autoimmune skin disease. The most common form in dogs is pemphigus foliaceus, which manifests as erosions and crusting of the skin and mucocutaneous junctions. Pemphigus vulgaris is more rare and manifests as blister-like lesions in the mouth and at mucocutaneous junctions. Bullous pemphigoid is most commonly seen in Dobermanns and Collies and appears as a scald-like lesion of the groin.[81]
Leishmaniasis is a protozoan disease of people and animals. It is transmitted by sandflies and is uncommon in North America. The two forms of the disease are visceral and cutaneous. The cutaneous form of leishmaniasis is most common in people and appears as one or more painless ulcers on the skin. Visceral leishmaniasis is less common and is characterized by fever, weight loss, enlarged spleen, and anemia. Dogs can develop both forms at the same time and have a variety of symptoms.

Diabetes in dogs is a complex disease caused by either a lack of the hormone insulin or an inadequate response to insulin. After a dog eats, his digestive system breaks food into various components, including glucose—which is carried into his cells by insulin, a hormone secreted by the pancreas. When a dog does not produce insulin or cannot utilize it normally, his blood sugar levels elevate. The result is hyperglycemia, which, if left untreated, can cause many complicated health problems for a dog.
Canine parvovirus is caused by infection with CPV, most often, CPV-2a or CPV-2b. All dogs are at risk for developing canine parvovirus. Puppies less than 4 months old and dogs that have not been vaccinated against the virus are at increased risk for infection.
Rocky Mountain spotted fever (RMSF) is a bacterial disease transmitted to dogs and people by ticks. Dogs show a variety of symptoms similar to those in people, including fever, lameness, coughing, vomiting and diarrhea, and swelling of the face or extremities.

Yes, puppies are a bundle of energy, but even they need disciplined exercise like leash walks. However, don’t start running and hiking with your pooch until your larger-breed dog is at least 1.5 years old. This will help avoid injuries while the growth plates in the legs and other long bones are still knitting closed. Tip: Be sure to build up your dog’s endurance, just as you did your own, if you’re hoping to take it with you on those marathon-training runs.
Pica in dogs may be a sign of Immune-mediated hemolytic anemia, especially when it involves eating substances such as tile grout, concrete dust, and sand. Dogs exhibiting this form of pica should be tested for anemia with a Complete blood count including Hematocrit levels, or Packed cell volume.[46][47]
Nuclear sclerosis is a consistent finding in dogs greater than seven years old. Nuclear sclerosis appears as a bilateral bluish-grey haziness at the nucleus, or center of the lens,[62] and has little effect on vision.[66] This is may be confused with cataracts.[67]
Developmental orthopedic diseases include panosteitis and hypertrophic osteodystrophy. Panosteitis occurs in large and giant breed dogs usually between the age of five and fourteen months and manifests as fever, pain, and shifting leg lameness. Hypertrophic osteodystrophy is also seen in young large and giant breed dogs and is characterized by pain, lameness, fever, and swelling of the long bone metaphysis.

Humans can also spread the virus by touching a dog or item contaminated with the virus and then transferring that to other dogs, says Weese, which is why it’s so important for dog owners to wash their hands after contact with a sick animal.
There are no specific steps you can take to prevent your dog from contracting the disease, but there is some evidence of seasonal fluctuation, with most cases appearing between November and June. New advice suggests keeping your dog away from very muddy areas. 
Dental disease is one of the most common diseases in dogs. Accumulation of plaque and subsequently tartar leads to gingivitis and then periodontitis (gum disease). Periodontitis leads to loss of the bony attachment of the teeth and tooth loss. Preventive measures include tooth brushing, providing an appropriate diet (avoiding tinned and other soft foods and providing dental chew treats) and dental scaling and polishing. Cavities are uncommon in dogs.

Overdoses of vitamins can be harmful in dogs. As an example, calcium in excess can cause bone problems, especially in the large-breed dogs. Over-supplementation of vitamins A and D can cause vitamin toxicity in dogs.[68] Excess vitamin A can cause dehydration, joint pain and can also harm the blood vessels, while too much vitamin D can cause muscular atrophy, or loss of appetite.
Mouse and rat poison is commonly found in the house or garage. Dogs readily eat these poisons, which look like small green blocks and are very attractive to them. The poisons work by depleting stores of Vitamin K in the body, without it, blood cannot clot properly. Clinical signs of poisoning include depression, weakness, difficulty breathing, bruising, and bleeding from any part of the body. These clinical signs often take 3 to 4 days to show up. A blood test will show that the blood is not clotting properly. If the poison has only recently been ingested (within 2 to 3 hours), the dog should be given apomorphine or hydrogen peroxide to make it vomit. Activated charcoal can be given to absorb any remaining poison in the gastrointestinal tract. Then the dog is given Vitamin K supplementation for 3 to 4 weeks, depending on the type of poison. At the end of treatment, the clotting times should be tested again. The prognosis is good in these cases. However, if the dog is already showing signs of poisoning, it is too late to try to remove the poison from the body. A whole blood transfusion or plasma is given to treat the anemia and to try to control bleeding. Vitamin K is also given. The prognosis is poor in these cases.
What to look for: Arthritis usually, but not always, affects dogs as they grow older. It is the most common health problem in older pets. Your dog will eventually begin to move around less and take more time getting up from lying or seated positions.
Symptoms are basic: abdominal heaving and drooling caused by nausea. If your dog also has diarrhea, blood in the vomit, seems lethargic, continues vomiting, or can’t hold down liquids, contact your vet right away to prevent life-threatening dehydration.
Congenital vertebral anomalies, including butterfly, block, and transitional vertebrae, and hemivertebrae, are a collection of malformations of the spine in animals. Most are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability.[6]
Does your dog wolf his food down in a blink of an eye? Then he may be at risk of bloat, which is basically an enlarged stomach; this can become even more complicated if the stomach also turns. This prevents fluid and air from escaping the stomach, which prevents the dog from belching or vomiting.

Subaortic stenosis, or SAS, is a genetic ailment that causes a narrowing of the passage of blood between the heart and the aorta. This leads to heart problems and sometimes sudden death. It affects larger breeds such as the Newfoundland Dog and the Golden Retriever.[15] In some dogs, such as collies, the blue merle or harlequin coloring is actually the heterozygote of a partially recessive gene preventing proper development of the nervous system; therefore, if two such dogs are mated, on the average one quarter of the puppies will have severe genetic defects in their nervous systems and sensory organs ranging from deafness to fatal flaws.
Elbow dysplasia is a condition found more commonly in large breeds. It incorporates several different hereditary conditions of the elbow, including osteochondritis of the medial condyle of the humerus, fragmentation of the medial coronoid process of the ulna, and ununited anconeal process of the ulna.[6]
Poisoning with pain medications is common. Aspirin, paracetamol (acetaminophen, Tylenol), ibuprofen (Advil), and naproxen (Aleve) can all cause severe clinical signs in dogs, including vomiting blood, diarrhea, and abdominal pain.[57][58][59][60] Specifically, aspirin can cause metabolic acidosis and bleeding disorders, acetaminophen can cause liver disease, ibuprofen can cause kidney disease, and naproxen can cause ulcers in the stomach, which can perforate. Treatment depends on the clinical signs.
I am sorry to hear about this, Slugger. We would advise that anytime there is a such a drastic change in your pet’s behavior that you call to consult a vet. This sounds like a very specific incident that it will be hard to diagnose and treat from reading articles. Sending lots of healing vibes your way.
Symptoms of chocolate poisoning include vomiting, diarrhea, pacing, panting, and shaking. More serious cases could cause an irregular heart beat, seizures, heart attack, or even death. If you think you dog has eaten any chocolate, do not wait to take him to the doctor.

Hemorrhagic gastroenteritis is a disease of dogs characterized by sudden vomiting and bloody diarrhea. The symptoms are usually severe and can be fatal if not treated. It is most common in young adult dogs of any breed, but especially small dogs such as the Toy Poodle and Miniature Schnauzer.[6]
Vaccinating your dog doesn’t just protect him from rabies—it also protects your dog if he bites someone. Dogs who have bitten humans are required to be confined for at least 10 days to see if rabies develops.

The exact cause of diabetes is unknown. Autoimmune disease, genetics, obesity, chronic pancreatitis, certain medications and abnormal protein deposits in the pancreas can play a major role in the development of the disease.
The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.

Genetics and environmental factors also play a role in cancer development. Some credit the uptick in canine cancer rates to dogs simply living longer with better health care options. Other blame dog “junk” food for the rise, with brand-name foods using ingredients thought to cause cancer. Check the labels and avoid BHT, BHA, and ethoxyquin.
Onions cause hemolytic anemia in dogs (and cats).[44] Allyl propyl disulfide has been reported as being considered to be the main cause of onion poisoning in dogs.[44] Thiosulfate has also been reported as being implicated. Thiosulfate levels are not affected by cooking or processing. Occasional exposure to small amounts is usually not a problem, but continuous exposure to even small amounts can be a serious threat. Also garlic contains thiosulfate, even if to a significantly lesser extent, and it is also known to cause diarrhea and vomiting.
Cryptococcosis* is a fungal disease caused by Cryptococcus neoformans that affects both dogs and humans. It is a rare disease in dogs, with cats seven to ten times more likely to be infected. The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system.[20]
Atopy* is an allergy to a substance with which the dog is not necessarily in direct contact. It is a type I hypersensitivity to a substance that is inhaled or absorbed through the skin. Up to 10 percent of dogs are affected.[77] It is common in dogs, especially seen in breeds such as Labrador Retrievers, Golden Retrievers, and Shih Tzus. The most common symptom is itching. Affected areas include the underside, the face, the feet, and the ears.[78]

That could happen if a dog infected with canine flu also contracted a human flu, and the two strains combined to create a new virus that was capable of infecting humans. That would be a concern, says Weese, because it would create a novel virus that humans had no immunity to.
Bloat can affect any dog at any age but there are breeds more susceptible to it: usually large breed, deep-chested dogs like Great Danes, German shepherds, boxers, Labrador retrievers, bloodhounds, and weimaraners. Mid-size and smaller dogs aren’t much at risk, with the exception of basset hounds and dachshunds, who also have long, broad chests.

Malignant histiocytosis (histiocytic sarcoma) is an aggressive cancer found primarily in certain breeds including the Bernese Mountain Dog, rottweiler, golden retriever and flat coated retriever. It is characterized by infiltration of the joints, lungs, spleen, lymph nodes, and other organs by malignant histiocytes.[6]

The dog tapeworm is a parasite spread to dogs, cats, and people through the ingestion of infected fleas. This parasite is common but rarely causes illness in pets or people. Infections with Dipylidium caninum can sometimes be detected by finding rice-like segments of the tapeworm crawling near the anus or in fresh bowel movements. In severe infections, pets can lose weight and have mild diarrhea.

“Treatment is supportive, but is only successful in 20-30% of cases, which is why we’re encouraging all dog owners to use the online interactive guide to help them understand the clinical signs and confirmed locations of Alabama Rot.
As the name suggests, an infected mosquito injects a larva into the dog’s skin, where it migrates to the circulatory system and takes up residence in the pulmonary arteries and heart, growing and reproducing to an alarming degree. The effects on the dog are quite predictable, cardiac failure over a year or two, leading to death. Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and frequently does not succeed. Prevention is much the better course, via heartworm prophylactics which contain a compound which kills the larvae immediately upon infection without harming the dog. Often they are available combined with other parasite preventives.
Rocky Mountain spotted fever* is a rickettsial disease that occurs in dogs and humans. It is caused by Rickettsia rickettsii and spread by ticks of the genus Dermacentor. Signs are similar to human disease, including anorexia, fever, and thrombocytopenia.[12]
Garlic & Onions* are toxic to dogs. Onions, Garlic, Chives – can cause the destruction of red blood cells known as Heinz body anemia, a form of hemolytic anemia. No clear quantity has been established as to the onset of the anemia. But for garlic, if your dog consumes the equivalent of 1 teaspoon of garlic for every 10 pounds of their weight (1 teaspoon for a 10-pound dog) it can destroy red blood cells. Poisonous reaction can result from raw, cooked or dried onions, garlic, chives, including those included in powdered or dehydrated forms. Avoid all foods that contain onions or onion variants (such as spaghetti sauce).

Kennel cough is a term loosely used to describe a complex of respiratory infections—both viral and bacterial—that causes inflammation of a dog’s voice box and windpipe. It’s a form of bronchitis and is similar to a chest cold in humans.
Dog hookworms are tiny worms that can spread through contact with contaminated soil or sand. Dogs can also become infected with hookworms through accidentally ingesting the parasite from the environment or through their mother’s milk or colostrum. Young puppies are most often affected and might have dark, bloody stool and anemia. Severe infections in some puppies can lead to death.
The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.
Cancer is a class of diseases in which cells grow uncontrollably, invade surrounding tissue and may spread to other areas of the body. As with people, dogs can get various kinds of cancer. The disease can be localized (confined to one area, like a tumor) or generalized (spread throughout the body).
Pulmonary hypertension* is high pressure in the pulmonary artery. In dogs it can be caused by heartworm disease, pulmonary thromboembolism, or chronic hypoxemia (low oxygen). It can result in right-sided heart disease (cor pulmonale). Signs include difficulty breathing, cyanosis, and exercise intolerance.[49]
Facial nerve paralysis* is most commonly caused in dogs by trauma, otitis media, or as an idiopathic condition. Signs include an inability to blink, drooping of the ear, and drooping of the lips on the affected side, although in chronic conditions fibrosis occurs and the ear and lips may appear to be in an abnormal position.[60]

Certain breeds are prone to specific cancers. Boxers, Boston terriers and Golden Retrievers are among the breeds that most commonly develop mast cell tumors or lymphoma, while large and giant breeds like Great Danes and Saint Bernards are much more likely to suffer from bone cancer than smaller breeds.
Tapeworms, roundworms, hookworms, and whipworms are common internal parasites in dogs. And although any worm infestation can make your pooch uncomfortable, some, like hookworms, can be fatal in puppies. Signs your dog may have worms include:
Pick up and dispose of dog stools, especially in areas where children might play. Cleaning up after your dog will help keep the area clean and reduce the risk of spreading disease to people or other animals.
Although a certain form of diabetes—the type found in dogs less than a year of age—is inherited, proper diet and regular exercise can go a long way to avoid the development of diabetes. Aside from other negative effects, obesity is known to contribute to insulin resistance.

The Windsor-Essex County Health Unit in southwestern Ontario announced this week it has confirmed infections in two dogs brought to Canada from South Korea by a U.S.-based dog rescue group. Both dogs have the H3N2 strain and their new owners have placed each of them into quarantine, away from other pets.

How to treat: Vaccines can be administered regularly to prevent some types of kennel cough. If your dog catches kennel cough you should take him to your vet where he might be prescribed medications that will speed up the recovery process. Keep your pup away from other dogs (especially in public places where the illness can spread rapidly), and give him lots of rest. Once you see signs of recovery, take him for regular walks until he is himself again.
3. Dental disease: While everyone dreads “dog breath,” a stinky mouth is no joke. Both cats and dogs can develop tartar, gum disease, and cavities that require a professional dental cleaning. Dental disease is the perfect example of “an ounce of prevention is worth a pound of cure,” because bad oral health can also lead to dangerous heart and kidney conditions in pets. Teach your kittens and puppies that brushing their teeth is a normal part of your grooming routine and save your pet a dental procedure down the line.

Pica is an appetite for, or the behavior of eating, non-nutritive substances (e.g., sand, coal, soil, chalk, paper etc.). Pica can be dangerous to dogs, with a risk from eating dirt near roads that existed prior to the phaseout of tetraethyllead in gasoline or prior to the cessation of the use of contaminated oil (either used, or containing toxic PCBs) to settle dust. In addition to poisoning, there is a risk of gastro-intestinal obstruction or tearing in the stomach or blockage of the esophagus.

Avoid bites and scratches from dogs. Dog bites might become seriously infected or might be a source of rabies. Be cautious with unfamiliar animals. Approach dogs with care, even if they seem friendly.
Masticatory muscle myositis (MMM) is an inflammatory disease in dogs affecting the muscles of the jaw. Signs include swelling of the jaw muscles and pain on opening the mouth. In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus).[6]

Sensitivity to anaesthesia can occur in any breed, but sighthounds have been the breeds most documented to have anesthetic concerns. Sighthounds are known to have prolonged recovery times from ultra short-acting thiobarbiturates such as thiopental.[164]
Dogs in pet stores, animal shelters, and breeding kennels also are at increased risk. Overcrowding and poor sanitary conditions make it easier for the virus to spread. Certain breeds of dog (e.g., English springer spaniels, rottweilers, Doberman pinschers) and dogs that have another health condition may have a higher risk for developing severe disease.
Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs involving the retina, choroid, and sclera. It can be a mild disease or cause blindness. It is known to occur in Smooth and Rough Collies, Shetland Sheepdogs, Australian Shepherds, Border Collies, and Nova Scotia Duck Tolling Retrievers.[62]
Prostate cancer* is rare in dogs and occurs in both intact and neutered animals. It is malignant. The most common type is adenocarcinoma. Signs include blood in the urine and straining to urinate or defecate. It most commonly spreads to bone and the lungs.[161]
They’re commonly known as hot spots, but the medical term for those bare, inflamed, red areas you often see on dogs is acute moist dermatitis — a bacterial skin infection. Anything that irritates your dog’s skin enough to make him scratch or chew can lead to the pain and itch of hot spots, which, if left untreated, can quickly grow larger.

Foreign body is an object foreign to the body that becomes lodged in the gastrointestinal tract (or other part of the dog). Dogs are susceptible to gastrointestinal obstruction due to their ability to swallow relatively large objects and pass them through the esophagus. Foreign bodies most commonly become lodged in the stomach because of the inability to pass through the pyloric sphincter, and in the jejunum.
Cataracts* are an opacity in the lens of the eye. Most cataracts in dogs are caused by a genetic predisposition, but diabetes mellitus is also a common cause.[64] The only effective treatment is surgical removal.[65]
Patent ductus arteriosus* is one of the most common congenital heart defect in dogs around the world. It is inherited in toy and miniature Poodles, and seen commonly in German Shepherds, Pomeranians, Bichon Frises, and Malteses. Signs include a continuous heart murmur, bounding (strong) femoral pulse, tachypnea (increased breathing rate), dyspnea (labored breathing), and exercise intolerance.[49]
Corneal dystrophy is a condition characterized by bilateral, noninflammatory opacity of the cornea. It appears as grayish white lines, circles, or clouding of the cornea. Corneal dystrophy can also have a crystalline appearance.[62]

Entropion (eyelid folding inward) is a common condition in dogs, especially the Chow Chow, Shar Pei, St. Bernard, and Cocker Spaniel. Upper lid entropion involves the eyelashes rubbing on the eye, but the lower lid usually has no eyelashes, so hair rubs on the eye. Surgical correction is used in more severe cases.[62]

It is suspected the disease spreads from muddy and wooded areas – dog owners who do walk their dogs in these places are advised to wash off any mud as soon as possible, and of course, keep close control of their dogs at all times to monitor where they go.
With two rescue dogs brought to Canada being diagnosed with what are believed to be the country’s first cases of dog flu, dog owners are being warned to keep an eye out for the highly contagious virus.
Cerebellar abiotrophy is caused by the death of Purkinje cells in the cerebellum. It results in progressive ataxia beginning at a young age. It is most commonly seen in Kerry Blue Terriers and Gordon Setters.[56]
Corneal ulcer, or ulcerative keratitis, is an inflammatory condition of the cornea involving loss of its outer layer. They are caused by trauma, detergent burns, and infections. Other eye conditions can cause corneal ulcers, such as entropion, distichia, corneal dystrophy, and keratoconjunctivitis sicca.[62]
Grapes and raisins can cause acute kidney failure in dogs [38] (see also grape and raisin toxicity in dogs). The exact mechanism is not known, nor is there any means to determine the susceptibility of an individual dog. While as little as one raisin can be toxic to a susceptible 10 pounds (4.5 kg) dog, some other dogs have eaten as much as a pound of grapes or raisins at a time without ill effects. The affected dog usually vomits a few hours after consumption and begins showing signs of renal failure three to five days later. A mycotoxin is suspected to be involved, but one has not been found in grapes or raisins ingested by affected dogs. The reason some dogs develop renal failure following ingestion of grapes and raisins is not known.[39][40][41][42] The most common pathological finding is proximal renal tubular necrosis.[43]
Rabies (hydrophobia) is a fatal viral disease that can affect any mammal, although the close relationship of dogs with humans makes canine rabies a zoonotic concern. Vaccination of dogs for rabies is commonly required by law. Please see the article dog health for information on this disease in dogs.[1]
Female cats and dogs are seven times more likely to develop mammary tumors if they are not spayed before their first heat cycle.[73] The high dietary estrogen content of the average commercial pet food may be contributing factors in the development of mammary cancer, especially when these exogenous sources are added to those normal estrogens produced by the body. Dog food containing soybeans or soybean fractions have been found to contain phytoestrogens in levels that could have biological effects when ingested longterm.[74]
Food allergy* in dogs is commonly manifested as itching, especially of the face, paws, and the underside. Skin testing has proved unreliable, and a trial of a hypoallergenic diet is usually used for diagnosis.[80]
Horner’s syndrome* results from damage to the sympathetic innervation of the eye. Signs include enophthalmos (sunken eye), miosis (small pupil), elevated third eyelid, and ptosis (drooping of the upper eyelid). Usually the syndrome in dogs is idiopathic, but it can also be caused by trauma, tumors, or ear infections.[71]
Signs of vestibular disease include head tilt, circling, nystagmus (an abnormal movement of the eyes), and difficulty or inability to stand. These clinical signs are similar to those seen in humans experiencing vertigo. Vestibular disease may have many causes. Elderly dogs are susceptible to an idiopathic (meaning due to unknown causes) form of vestibular disease commonly called “old dog vestibular disease” or idiopathic peripheral vestibular disease. The signs may improve rapidly or take a few days. Less commonly, vestibular signs can also be caused by inner ear disease, a brain tumor, a stroke, or other causes. The major risk with idiopathic peripheral vestibular disease is that the dog is often unable to eat, drink, or go outside to urinate or defecate. These cases must receive supportive therapy of intravenous fluids and nutrition; a light sedative is sometimes administered, as the dog may be very stressed by the experience.
“He is soooo cute,” you thought when you first laid eyes on your dog. And—yay!—he seemed to like you too. So you brought him home—only to realize that maybe you weren’t totally prepared for the work this relationship involved. Well, your mom was right (again): Owning a dog IS a big responsibility, from training to feeding to keeping it stress-free. “We don’t have that many years with our dogs,” says Whole Dog Journal editor Nancy Kerns. Here’s how to make sure each day is filled with health—and happiness for you both.
Mouse and rat poisons containing cholecalciferol cause hypercalcemia and hyperphosphatemia in dogs. Clinical signs include depression, loss of appetite, vomiting blood, weakness, and shock. Treatment is as above for recent exposure. When hypercalcemia occurs (which can take 1 to 2 weeks), treatment is with intravenous fluids (saline), diuretics, corticosteroids, and calcitonin. Long term prognosis is good once the dog is stabilized.

Lymphangiectasia is an intestinal disease of dogs characterized by chronic diarrhea and loss of proteins such as serum albumin and globulin. It is considered to be a chronic form of protein-losing enteropathy. Breeds commonly affected include the Soft-Coated Wheaten Terrier, Norwegian Lundehund, Basenji, and Yorkshire Terrier.[6]
As the name suggests, an infected mosquito injects a larva into the dog’s skin, where it migrates to the circulatory system and takes up residence in the pulmonary arteries and heart, growing and reproducing to an alarming degree. The effects on the dog are quite predictable, cardiac failure over a year or two, leading to death. Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and frequently does not succeed. Prevention is much the better course, via heartworm prophylactics which contain a compound which kills the larvae immediately upon infection without harming the dog. Often they are available combined with other parasite preventives.
Staphylococcus aureus is a common type of bacteria that is normally found on the skin of people and animals. Methicillin-resistant Staphylococcus aureus (MRSA) is the same bacterium that has become resistant to some antibiotics. Dogs and other animals often can carry MRSA without being sick, but MRSA can cause a variety of infections, including of the skin, respiratory tract, and urinary tract.
My dog will all the sudden get a burst of energy and run so fast he can’t stop and he will run right into things. Now he does this exorcist thing with his head, turning it back violently, teeth chattering and trying to bite his ear kind of thing and will not let anyone near him at all. I think he is having seizures but I’m not sure. I need help. Anyone??
Hypoadrenocorticism, also known as Addison’s disease, is a reduction of production of glucocorticoids and mineralocorticoids by the adrenal glands. There is more familiarity with the glucocortcoids, such as cortisol; mineralocorticoids control the amount of potassium, salt and water in the body.[106][107][108] It is most commonly caused by destruction of adrenal tissue, probably by autoimmune disease. Signs include increased drinking and urination, vomiting, diarrhea, collapse, shivering and weight loss; at times neither the causes nor symptoms are especially specific.[109][110] Because of this it is sometimes referred to as “the Great Mimic” or “the Great Imitator”.[107][111] It is possible not to see any symptoms of the disease until the adrenal cortex is 90% dysfunctional.[112] Addison’s can occur when regular steroid use is abruptly discontinued; during their use, the system the adrenal gland does not function at 100%. The system senses sufficient levels of these hormones in the body and does not signal for their production. Tapering the medication off gradually allows them to return to full production after discontinuation.[110][112] About 35% of affected dogs are not diagnosed until they experience an Addisonian crisis, which outwardly appears to be a “classic” shock and is a medical emergency.[105][112] Hyperkalemia[106] can develop and cause severe bradycardia. Only typical Addison’s patients have the risk of Addisonian crisis due to the lack of mineralocorticoids.[110] Treatment is with supplementation of mineralocorticoids in daily pills or a monthly injection. The atypical form and the form caused by abrupt withdrawal of steroids do not need mineralocorticoids.[110] Glucocorticoids are usually supplemented with oral prednisone.[113][114]
Vets4Pets, which has nearly 400 practices across the UK, is supporting the research work carried out by Anderson Moores Veterinary Specialists to help understand the disease, how it can be treated and possibly prevented.
Always take your dog to the veterinarian if you think he has an ear infection. In most cases, cleaning and medicating the ear canal will quickly clear up an infection. However, surgery can be needed for chronic infections or if forceful head shaking results in the rupture of a vessel within the outer part of the ear.
Note: Do not attempt to handle or capture a wild animal who is acting strangely (i.e., a nocturnal animal who is out during the day, an animal who acts unusually tame). Report the animal to local animal control officers as soon as possible.
5. Distemper: Distemper is a tragic, often fatal disease of dogs and puppies. While the distemper virus is part of the typical puppy vaccine series, puppies too young for vaccination and dogs who were never vaccinated are most vulnerable. The virus typically comes along with neurological symptoms, nasal discharge, and high fevers. It also has a high mortality rate, and the rare dogs who survive infection often bear long-term effects, such as seizures and hardened paw pads.
3. Dental disease: While everyone dreads “dog breath,” a stinky mouth is no joke. Both cats and dogs can develop tartar, gum disease, and cavities that require a professional dental cleaning. Dental disease is the perfect example of “an ounce of prevention is worth a pound of cure,” because bad oral health can also lead to dangerous heart and kidney conditions in pets. Teach your kittens and puppies that brushing their teeth is a normal part of your grooming routine and save your pet a dental procedure down the line.
Subaortic stenosis, or SAS, is a genetic ailment that causes a narrowing of the passage of blood between the heart and the aorta. This leads to heart problems and sometimes sudden death. It affects larger breeds such as the Newfoundland Dog and the Golden Retriever.[15] In some dogs, such as collies, the blue merle or harlequin coloring is actually the heterozygote of a partially recessive gene preventing proper development of the nervous system; therefore, if two such dogs are mated, on the average one quarter of the puppies will have severe genetic defects in their nervous systems and sensory organs ranging from deafness to fatal flaws.

Nasal cancer makes up one to two percent of all types of tumors in dogs. Adenocarcinoma is the most common type, followed by sarcomas such as fiborsarcoma and chondrosarcoma. Signs include sneezing and bloody nasal discharge.[161]
Most diseases that affect dogs or humans are not transferable between the two species. Diseases that can be transmitted from animals to humans are terrmed zoonoses. A well-known zoonosis is rabies, a viral infection transmitted through a bite. A common bacterial zoonosis is leptospirosis, transmitted through urine. Some of the most important zoonoses are parasitic. Zoonotic intestinal parasites transmitted through contact with feces include Toxocara canis (the canine roundworm), which causes toxocariasis, visceral larva migrans, and ocular larva migrans, and hookworms, which can cause cutaneous larva migrans. Zoonotic skin parasites include scabies, caused by the mite Sarcoptes scabiei. The most common zoonotic fungal disease is ringworm, caused in this case by Microsporum canis.
Trichiasis in dogs is hair from the eyelid growing in the wrong direction and rubbing on the eye, causing irritation. It usually occurs at the lateral upper eyelid, especially in the English Cocker Spaniel.[62]
Vestibular disease* is an uncommon condition in older dogs. Most cases are idiopathic, but it can also be caused by otitis interna, or inner ear infection, tumors, and encephalitis. Signs include nystagmus, head tilt, circling, vomiting, and falling to one side. Idiopathic vestibular disease will usually resolve in a few days to a few weeks.[173]
As a dog parent, it is important to recognize the signs and symptoms of common illnesses so you can seek veterinary help for your canine friend as soon as possible. Read on for information about diseases and other medical inflictions that frequently impact dogs.
It is suspected the disease spreads from muddy and wooded areas – dog owners who do walk their dogs in these places are advised to wash off any mud as soon as possible, and of course, keep close control of their dogs at all times to monitor where they go.
Pemphigus is an uncommon autoimmune skin disease. The most common form in dogs is pemphigus foliaceus, which manifests as erosions and crusting of the skin and mucocutaneous junctions. Pemphigus vulgaris is more rare and manifests as blister-like lesions in the mouth and at mucocutaneous junctions. Bullous pemphigoid is most commonly seen in Dobermanns and Collies and appears as a scald-like lesion of the groin.[81]
Although the dog is an animal, still, he is one of the most honest companions of the human being. He usually relies on his pet owner for healthy care. Well, being a pet owner you must be aware of your canine friend health condition. In this regard, I can say that the ear infection(signs- swelling, redness of the ear canal, vigorous scratching), worms-including(tapeworms, hookworms, roundworms), flea attacks(signs- excessive licking, hair loss), hot spots, vomiting, diarrhea etc, are some of the common health issues that your canine friend usually suffers from the lack of care and treatment. Thus, my suggestion is, you must stop this negligence and consult an
Ringworm is a condition caused by a fungus that can infect skin, hair, and nails of both people and animals. Ringworm is transmitted from animals to people through direct contact with an infected animal’s skin or hair. Puppies are most commonly affected and can have circular areas of hair loss anywhere on the body.
Bilious vomiting syndrome is vomiting in response to bile-induced inflammation of the stomach. Bile salts interfere with the gastric mucosal barrier, allowing acid to irritate the stomach lining and cause gastritis.[146]
Orthopedic diseases in dogs can be developmental, hereditary, traumatic, or degenerative. Because of the active nature of dogs, injuries happen frequently. One of the most common of these is an anterior cruciate ligament injury, a condition which often requires surgery. Bone fractures are a frequent occurrence in outdoor dogs due to trauma from being hit by cars. Degenerative joint disease is common in older dogs and is one of the most likely reasons for prescription of non-steroidal anti-inflammatory drugs.
Dog treats are often given to pets as a reward for something they did or just to let them chew on a bone, which works their jaw muscles and helps keep their teeth clean.[63] Although dog treats carry high benefits for dogs’ teeth, they can also be a source of problems when given excessively. The human food treats are usually the ones that cause the most trouble for dogs.
Leishmaniasis is a protozoan disease of people and animals. It is transmitted by sandflies and is uncommon in North America. The two forms of the disease are visceral and cutaneous. The cutaneous form of leishmaniasis is most common in people and appears as one or more painless ulcers on the skin. Visceral leishmaniasis is less common and is characterized by fever, weight loss, enlarged spleen, and anemia. Dogs can develop both forms at the same time and have a variety of symptoms.
Diabetes insipidus* in dogs can be central, caused by a lack of antidiuretic hormone (ADH), or nephrogenic, caused by a lack of response of the kidneys to ADH. Neither form is common. Central diabetes insipidus (CDI) is usually idiopathic, but can also be caused by head trauma[123] or tumors of the brain. Nephrogenic diabetes insipidus (NDI) can be primary (hereditary) or secondary (caused by a variety of metabolic[124] and renal diseases, including Cushing’s syndrome and pyometra). Because the disease is characterized by an inability to concentrate urine, the most common sign is increased drinking and urinating.[125][126] Treatment of CDI is to use desmopressin, a synthetic analog of ADH. Treatment of NDI is to treat the underlying cause, if any.[127]
Ear infections are common in dogs, particularly breeds with hanging ears, such as Beagles, and dogs with narrow ear canals, such as Cocker Spaniels. Other predisposing factors include allergies, ear parasites, and hypothyroidism.[74]
Malignant histiocytosis (histiocytic sarcoma) is an aggressive cancer found primarily in certain breeds including the Bernese Mountain Dog, rottweiler, golden retriever and flat coated retriever. It is characterized by infiltration of the joints, lungs, spleen, lymph nodes, and other organs by malignant histiocytes.[6]
Bloat can affect any dog at any age but there are breeds more susceptible to it: usually large breed, deep-chested dogs like Great Danes, German shepherds, boxers, Labrador retrievers, bloodhounds, and weimaraners. Mid-size and smaller dogs aren’t much at risk, with the exception of basset hounds and dachshunds, who also have long, broad chests.
Heartworm is easily preventable with an inexpensive, chewable pill or topical medication available as a vet’s prescription. The pills or topical are usually administered monthly and can be given to dogs under 6 months of age without a blood test. Older animals must be screened for the disease prior to starting medication.
  Many studies show the health benefits of dog ownership. Dogs not only provide comfort and companionship, but several studies have found that dogs decrease stress and promote relaxation. Dogs have positive impacts on nearly all life stages. They influence social, emotional, and cognitive development in children, promote an active lifestyle, and have even been able to detect oncoming epileptic seizures or the presence of certain cancers. But for all the positive benefits of keeping dogs, pet owners should be aware that dogs can carry germs that make people sick.
“Dogs will get a fever, they’ll feel kind of run down, they’ll get a runny nose, runny eyes, and a cough. That’s usually the main thing the main things will people will see,” he told CTV’s Your Morning Wednesday, adding that some dogs also develop mild diarrhea or vomiting.
Heartworm is a parasitic worm that lives in the heart and pulmonary arteries of an infected animal. The worms travel through the bloodstream—harming arteries and vital organs as they go—ultimately completing their journey to the vessels of the lung and the heart chamber about six months after the initial infection. Several hundred worms can live in one dog for five to seven years.
How to treat: A steady diet and regular exercise are the two things needed when your dog is overweight. It’s important to recognize the severity of your dog’s obesity and be sure to administer the right changes in nutrition and exercise. Too much exercise, or too significant a reduction in food, can cause other issues, so you should consult your vet before making any drastic changes to the diet.
Pericardial effusion* is a collection of fluid in the pericardium. It is usually serosanguinous (bloody fluid). Serosanguinous accumulation can be caused by cancer, usually hemangiosarcoma or a heart base tumor, idiopathic pericarditis. Rare causes include trauma, clotting disorders, and left atrial rupture. Serous accumulation is rare and caused by heart failure, peritoneopericardial diaphragmatic hernias, uremia, pericardial cysts, or hypoalbuminemia. Rarely pericardial effusion can be caused by infection and consist of pus. An echocardiogram should be done prior to draining the fluid, if possible, to identify the cause (e.g., tumor). Drainage of the fluid (pericardiocentesis) relieves the clinical signs and, in the case of idiopathic pericarditis, can be curative.[49]

Canine glaucoma is an increase of pressure within the eye. It is a common condition in dogs. It can be caused by abnormal development of the drainage angle of the eye, lens luxation, uveitis, or cancer. Cocker Spaniels, Poodles, and Basset Hounds are predisposed.[69]
Alcohols Commonly encountered alcohols in veterinary medicine are isopropanol and methanol found in household products and ethanol from alcoholic beverages. They all pose toxicity to dogs. Isopropanol which is found in rubbing alcohol has twice the toxicity of ethanol; however methanol which can be found in windshield washer fluid does not have the same retinal and neuronal toxicity on dogs as it does to humans and primates due to the differences in the way its metabolite formic acid is processed.[56]
Antifreeze* is very dangerous to dogs and causes central nervous system depression and acute renal failure. Treatment needs to be within eight hours of ingestion to be successful.[168] See Ethylene glycol poisoning.
Bacterial diseases in dogs are usually not contagious from dog to dog; instead they are usually the result of wound colonization, opportunistic infections secondary to decreased resistance (often the result of viral infections), or secondary to other conditions (pyoderma secondary to skin allergies or pyometra secondary to cystic endometrial hyperplasia). These examples are not considered infectious diseases because they do not satisfy Koch’s postulates – for example Staphylococcus intermedius, a commonly isolated bacteria from skin infections in dogs, would not cause pyoderma when introduced to a healthy dog. In all likelihood that type of bacteria is already present on the skin of a healthy dog.
If your dog will be housed outside, provide shelter such as a doghouse for when it is cold or rainy and shade for when it is hot. Protecting your dog from the changes in weather will reduce stress and help keep it healthy.
Tick paralysis* is a disease in dogs caused by a neurotoxin found in the saliva of female ticks. Dermacentor species predominate as a cause in North America, while Ixodes mainly causes the disease in Australia. There is a gradual onset of signs, which include incoordination progressing to paralysis, changed voice, and difficulty eating.[56]
Liver failure* is common. Signs include vomiting, loss of appetite, weight loss, and jaundice. Causes include bacterial or viral infection, toxic insult, cancer, copper storage diseases, or it may be idiopathic.[175]

Fleas and ticks of various species can be acquired and brought home by a dog, where they can multiply and attack humans (and vice versa). These two parasites are particularly important to note, now that tick-borne Lyme Disease has become endemic throughout a large area, in addition to other similar diseases such as Rocky Mountain Spotted Fever. Although dogs do not seem to be as susceptible to such diseases as humans, similar rickettsial diseases have been spread by dogs to humans through such mechanisms as a dog killing an infected rabbit, then shaking itself off in the house near enough to its owners to fatally infect most of the family.
Dogs in pet stores, animal shelters, and breeding kennels also are at increased risk. Overcrowding and poor sanitary conditions make it easier for the virus to spread. Certain breeds of dog (e.g., English springer spaniels, rottweilers, Doberman pinschers) and dogs that have another health condition may have a higher risk for developing severe disease.

They’re commonly known as hot spots, but the medical term for those bare, inflamed, red areas you often see on dogs is acute moist dermatitis — a bacterial skin infection. Anything that irritates your dog’s skin enough to make him scratch or chew can lead to the pain and itch of hot spots, which, if left untreated, can quickly grow larger.
How to treat: Like humans, dogs should get regular insulin injections (up to twice a day) to control diabetes. Oral medications and a high-fiber diet can also work to reverse the disease and get your dog back to a healthy state.
There are no specific steps you can take to prevent your dog from contracting the disease, but there is some evidence of seasonal fluctuation, with most cases appearing between November and June. New advice suggests keeping your dog away from very muddy areas. 
Often times they suffer in silence, unable to tell us if their tummy hurts or what aches. As pet parents, we try to take the best care of our little guys and gals, but it can be hard when they can’t tell us what’s wrong.
The best outcomes seem to be achieved by catching it early and the animal receiving high-quality veterinary care. Whilst some infected dogs do survive the treatments of skin sores and kidney failure, unfortunately, many do not – it is estimated that treatment is only successful in around 20-30% of cases.
Masticatory muscle myositis (MMM) is an inflammatory disease in dogs affecting the muscles of the jaw. Signs include swelling of the jaw muscles and pain on opening the mouth. In chronic MMM there is atrophy of the jaw muscles, and scarring of the masticatory muscles due to fibrosis may result in inability to open the mouth (trismus).[6]
Lyme disease is a bacterial disease of people and animals transmitted by ticks. In dogs the most common signs of illness of Lyme disease are lameness, fever, reluctance to eat, lack of energy, and enlarged lymph nodes, with or without swollen, painful joints.
Gastric dilatation volvulus, commonly known as bloat, is a serious condition in which the stomach swells with air (gastric dilatation), sometimes twisting on itself (volvulus). Deep-chested breeds are at a higher risk of bloating. Factors that predispose dogs to this condition are intestinal foreign bodies, intestinal cancer, intussusception, and other intestinal diseases. It has a poor prognosis.[142]
That could happen if a dog infected with canine flu also contracted a human flu, and the two strains combined to create a new virus that was capable of infecting humans. That would be a concern, says Weese, because it would create a novel virus that humans had no immunity to.
There are topical medicines to repel and kill ticks you put directly on your dog’s fur, like Frontline and K9 Advantix. There are also pills, like NexGard, and even collars your dog can wear, like Preventic. Just keep in mind the effectiveness of topical medicines decreases through the month, especially if your dog goes swimming or has a bath. Year-round prevention is best.

Pasteurellosis is a bacterial disease associated with animal bites and scratches. Pasteurella is a normal bacterium that lives in the mouths of healthy dogs. The bacteria do not typically make dogs sick; however, dogs can develop abscesses or skin infections in places where they were scratched or bitten by another animal.
Infectious diseases that affect dogs are important not only from a veterinary standpoint, but also because of the risk to public health; an example of this is rabies. Genetic disorders also affect dogs, often due to selective breeding to produce individual dog breeds. Due to the popularity of both commercial and homemade dog foods, nutrition is also a heavily studied subject.
Prostate cancer* is rare in dogs and occurs in both intact and neutered animals. It is malignant. The most common type is adenocarcinoma. Signs include blood in the urine and straining to urinate or defecate. It most commonly spreads to bone and the lungs.[161]
Systemic lupus erythematosus (SLE)* is an immune system disease characterized by the presence of antibodies to nucleic acid and/or antibodies to red blood cells, platelets, lymphocytes, clotting factors, and thyroglobulin. The disease can result in deposition of immune complexes or autoimmune disease. Immune complex deposition can cause vasculitis, meningitis, neuritis, and joint and skin disease. The most commons signs are hemolytic anemia or thrombocytopenia.[181]

Leptospirosis is a bacterial disease of people and animals that is transmitted through contaminated water and urine or other body fluids from an infected animal. It is difficult to detect early stages of leptospirosis in animals, but the disease can lead to kidney and liver failure if left untreated.
There are some bacteria that are contagious from dog to dog. The most notable of these are Bordetella bronchiseptica, one of the causes of kennel cough, Leptospira sp, which cause leptospirosis,[3][4] and Brucella canis, cause of brucellosis in dogs. There are also common tick-borne bacterial diseases, including Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever.
Skin diseases are very common in dogs. Atopy, a chronic allergic condition, is thought to affect up to 10 percent of dogs.[16] Other skin diseases related to allergies include hot spots and pyoderma, both characterized by secondary bacterial infections, food allergy, ear infections, and flea allergy dermatitis. Canine follicular dysplasia is an inherited disorder of the hair follicles resulting in alopecia (baldness). Mange is an infectious skin disease caused by mites. Endocrine diseases such as hypothyroidism and Cushing’s syndrome can also manifest as skin problems like alopecia or recurring bacterial infections. Another class of integumentary malady is hygromas, a swelling typically on or near the elbow joint. Nutrition may also play a role in skin disease, as deficiencies in certain nutrients may result in scaling, redness, oiling, balding, and/or itching of the skin.[17](See dog skin disorders for specific nutrients that impacts skin)
Alabama dog rot was first identified amongst greyhounds in the state of Alabama in the 1980s. After this first flair up, the number of reported cases dwindled and as no clinical research was carried out, the disease was almost relegated to history. Because no one has been able to determine what causes the disease, it is now only recognisable by its collection of clinical symptoms.

Coonhound paralysis is a type of polyradiculoneuritis seen in Coonhounds. The cause has been related to a raccoon bite. Signs include rear leg weakness progressing rapidly to paralysis, and decreased reflexes.[6]
Osteochondritis dissecans (OCD) is separation of immature articular cartilage from underlying bone. It is caused by osteochondrosis, which is characterized by abnormal endochondral ossification of epiphyseal cartilage. It is most commonly seen in the stifle, elbow, shoulder, and hock.[37]
Subvalvular aortic stenosis (Subaortic stenosis; SAS) is a congenital disease in dogs characterized by left ventricular outflow tract obstruction by a discrete ring or tunnel of fibrous tissue immediately below the aortic valve. It is inherited in Newfoundlands, and also found in Golden Retrievers, Rottweilers, Boxers, Bulldogs, German Shepherds, and Samoyeds. Signs include a left basilar systolic heart murmur, weak femoral pulse, fainting and exercise intolerance. Dogs with severe SAS are predisposed to dying suddenly.[49]

“If you think your dog is too skinny, it’s probably the right weight,” Case say. Dogs with excess weight are more prone to joint problems and diabetes, among other health issues (sounds familiar). How to tell if Fluffy is chubby? “It’s all about the feel,” she adds. “Ribs shouldn’t be visible, but easily felt.” Tip: Rub your hands up and down your dog’s flank. You should feel the ridges of its ribs without having to push in to find them.
Pericardial effusion* is a collection of fluid in the pericardium. It is usually serosanguinous (bloody fluid). Serosanguinous accumulation can be caused by cancer, usually hemangiosarcoma or a heart base tumor, idiopathic pericarditis. Rare causes include trauma, clotting disorders, and left atrial rupture. Serous accumulation is rare and caused by heart failure, peritoneopericardial diaphragmatic hernias, uremia, pericardial cysts, or hypoalbuminemia. Rarely pericardial effusion can be caused by infection and consist of pus. An echocardiogram should be done prior to draining the fluid, if possible, to identify the cause (e.g., tumor). Drainage of the fluid (pericardiocentesis) relieves the clinical signs and, in the case of idiopathic pericarditis, can be curative.[49]

Although a certain form of diabetes—the type found in dogs less than a year of age—is inherited, proper diet and regular exercise can go a long way to avoid the development of diabetes. Aside from other negative effects, obesity is known to contribute to insulin resistance.
How to treat: Vaccines can be administered regularly to prevent some types of kennel cough. If your dog catches kennel cough you should take him to your vet where he might be prescribed medications that will speed up the recovery process. Keep your pup away from other dogs (especially in public places where the illness can spread rapidly), and give him lots of rest. Once you see signs of recovery, take him for regular walks until he is himself again.
Liver failure* is common. Signs include vomiting, loss of appetite, weight loss, and jaundice. Causes include bacterial or viral infection, toxic insult, cancer, copper storage diseases, or it may be idiopathic.[175]
Rabies (hydrophobia) is a fatal viral disease that can affect any mammal, although the close relationship of dogs with humans makes canine rabies a zoonotic concern. Vaccination of dogs for rabies is commonly required by law. Please see the article dog health for information on this disease in dogs.[1]
It is not yet clear whether or not vitamins and supplements should be administered in dogs—opinions among veterinarians vary widely. While some think that vitamins and supplements are necessary and can improve the health of a dog, others believe that they are unnecessary and may harm the dog. According to the U.S. Food and Drug Administration (FDA), dogs receive a complete and balanced diet from the commercially processed dog food alone. Pet owners who give their dogs homemade diets may incorporate extra vitamins and supplements.
Urinary tract infection*, specifically cystitis or bladder infection, is common in dogs and usually caused by bacteria. Signs include blood in the urine (hematuria), difficulty urinating (dysuria), and frequent urination (polyuria).[154] The most common types of bacteria cultured from the urine of dogs with cystitis are E. coli, Staphylococcus spp., Proteus mirabilis, Streptococcus spp., Klebsiella pneumoniae, Pseudomonas aeruginosa, and Enterobacter spp.[155]
Congenital diaphragmatic hernia* is uncommon, and is usually caused by trauma. Congenital diaphragmatic hernias are usually communications between the peritoneum and pericardium and are usually incidental findings.[178]
Glomerulonephritis* is the presence of immune complexes in the glomerulus, resulting in leakage of protein into the urine. It can be caused by cancer, heartworm disease, pyometra, rickettsial infection, or systemic lupus erythematosus.[151] It can result in chronic kidney failure, hypoalbuminemia, which can cause ascites and peripheral edema, and nephrotic syndrome, which can cause hypertension or hypercoagulability.[152]
Bloat can affect any dog at any age but there are breeds more susceptible to it: usually large breed, deep-chested dogs like Great Danes, German shepherds, boxers, Labrador retrievers, bloodhounds, and weimaraners. Mid-size and smaller dogs aren’t much at risk, with the exception of basset hounds and dachshunds, who also have long, broad chests.
People most often become infected through flea bites or from contact with body fluids of infected animals. An example is a hunter skinning an infected rabbit or other animal. Bubonic plague is the most common form; symptoms include sudden onset of high fever, chills, headache, malaise, and swollen lymph nodes. The other two forms of plague, septicemic and pneumonic, cause more severe disease.
Foreign body is an object foreign to the body that becomes lodged in the gastrointestinal tract (or other part of the dog). Dogs are susceptible to gastrointestinal obstruction due to their ability to swallow relatively large objects and pass them through the esophagus. Foreign bodies most commonly become lodged in the stomach because of the inability to pass through the pyloric sphincter, and in the jejunum.
Dental disease is one of the most common diseases in dogs. Accumulation of plaque and subsequently tartar leads to gingivitis and then periodontitis (gum disease). Periodontitis leads to loss of the bony attachment of the teeth and tooth loss. Preventive measures include tooth brushing, providing an appropriate diet (avoiding tinned and other soft foods and providing dental chew treats) and dental scaling and polishing. Cavities are uncommon in dogs.
Dogs in pet stores, animal shelters, and breeding kennels also are at increased risk. Overcrowding and poor sanitary conditions make it easier for the virus to spread. Certain breeds of dog (e.g., English springer spaniels, rottweilers, Doberman pinschers) and dogs that have another health condition may have a higher risk for developing severe disease.
Nutmeg is highly neurotoxic to dogs and causes seizures, tremors, and nervous system disorders which can be fatal. Nutmeg’s rich, spicy scent is attractive to dogs which can result in a dog ingesting a lethal amount of this spice. Eggnog and other food preparations which contain nutmeg should not be given to dogs.[45][46][47]
Aspergillosis* is a fungal disease that in dogs is caused primarily by Aspergillus fumigatus. Infection is usually in the nasal cavity. Typical signs in dogs include sneezing, nasal discharge, bleeding from the nose, and ulcerations of the nose.[23]
As a dog parent, it is important to recognize the signs and symptoms of common illnesses so you can seek veterinary help for your canine friend as soon as possible. Read on for information about diseases and other medical inflictions that frequently impact dogs.
I love playing with my family. Running, jumping, swimming: it’s all great. But my favorite is fetch. For some reason, when we play fetch with my Humunga Stache, my family seems to have even more fun than usual. There’s lots of laughing and they take extra pictures of me. I don’t know why, but if it makes them happy, it’s fine with me!
It is suspected the disease spreads from muddy and wooded areas – dog owners who do walk their dogs in these places are advised to wash off any mud as soon as possible, and of course, keep close control of their dogs at all times to monitor where they go.

Congenital vertebral anomalies, including butterfly, block, and transitional vertebrae, and hemivertebrae, are a collection of malformations of the spine in animals. Most are not clinically significant, but they can cause compression of the spinal cord by deforming the vertebral canal or causing instability.[6]
Vaccinations are an important preventative animal health measure. The specific vaccinations recommended for dogs varies depending on geographic location, environment, travel history, and the activities the animal frequently engages in. In the United States, regardless of any of these factors, it is usually highly recommended that dogs be vaccinated against rabies, canine parvovirus, canine distemper, and infectious canine hepatitis (using canine adenovirus type 2 to avoid reaction). The decision on whether to vaccinate against other diseases, including leptospirosis, Lyme disease, Bordetella bronchiseptica, parainfluenza virus, and canine coronavirus, should be made between an owner and a veterinarian, taking into account factors specific to the dog.
Blastomycosis* is a fungal disease caused by Blastomyces dermatitidis that affects both dogs and humans. Dogs are ten times more likely to be infected than humans. The disease in dogs can affect the eyes, brain, lungs, skin, or bones.[15]
Although germs from dogs rarely spread to people, they might cause a variety of illnesses, ranging from minor skin infections to serious disease. To protect yourself and your family from getting sick:
Gastrointestinal cancer* is uncommon in dogs. The most common type is lymphoma. Nonlymphomatous esophageal cancer is especially rare, the most common types being squamous cell carcinoma, adenocarcinoma, leiomyosarcoma, and osteogenic sarcoma associated with the parasite Spirocerca lupi. Nonlymphomatous stomach cancer is usually an adenocarcinoma, and nonlymphomatous intestinal cancer is usually polyps, adenomas, adenocarcinomas, leiomyosarcomas, and leiomyomas.[161]
Distichia (including ectopic cilia) is an eyelash that arises from an abnormal spot on the eyelid. Distichiae usually cause no symptoms because the lashes are soft, but they can irritate the eye and cause tearing, squinting, inflammation, and corneal ulcers.[62]
Ventricular septal defect* is a hole in the division between the heart ventricles (interventricular septum). It is a congenital heart disease in dogs. There usually are no signs in dogs except for a heart murmur. However, a large defect can result in heart failure or in pulmonary hypertension leading to a right-to-left shunt.[49]
Certain breeds are more likely to develop particular tumors, larger ones especially. The Golden Retriever is especially susceptible to lymphoma, with a lifetime risk of 1 in 8.[19] Boxers and Pugs are prone to multiple mast cell tumors.[18] Scottish Terriers have eighteen times the risk of mixed breed dogs to develop transitional cell carcinoma, a type of urinary bladder cancer.[20]
There are several fungal diseases that are systemic in nature, meaning they are affecting multiple body systems. Blastomycosis, caused by Blastomyces dermatitidis, is a fungal disease that affects both dogs and humans, although it is only rarely zoonotic. It is found mainly in the United States in the Mississippi River and Great Lakes areas. It has also been reported in four Canadian provinces; Saskatchewan, Manitoba, Ontario and Quebec. Signs include weight loss, cough, fever, enlarged lymph nodes, draining skin lesions, eye inflammation with discharge, blindness, and lameness. Because dogs are ten times more likely to become infected from the environment than humans, they are considered to be sentinels for the disease. Treatment requires a minimum 60-90 day course of oral antifungal medication or in severe cases intravenous antifungal injections.[10]
Signs of vestibular disease include head tilt, circling, nystagmus (an abnormal movement of the eyes), and difficulty or inability to stand. These clinical signs are similar to those seen in humans experiencing vertigo. Vestibular disease may have many causes. Elderly dogs are susceptible to an idiopathic (meaning due to unknown causes) form of vestibular disease commonly called “old dog vestibular disease” or idiopathic peripheral vestibular disease. The signs may improve rapidly or take a few days. Less commonly, vestibular signs can also be caused by inner ear disease, a brain tumor, a stroke, or other causes. The major risk with idiopathic peripheral vestibular disease is that the dog is often unable to eat, drink, or go outside to urinate or defecate. These cases must receive supportive therapy of intravenous fluids and nutrition; a light sedative is sometimes administered, as the dog may be very stressed by the experience.
Trichiasis in dogs is hair from the eyelid growing in the wrong direction and rubbing on the eye, causing irritation. It usually occurs at the lateral upper eyelid, especially in the English Cocker Spaniel.[62]
On the other hand, acute kidney disease is largely preventable. Acute kidney disease is caused by a number of issues: poisoning, infection, or complication from medicines, to name a few. Symptoms are sudden and severe and can include fever, vomiting, change in water intake, change in appetite, and change in amount of urination.
As the name suggests, an infected mosquito injects a larva into the dog’s skin, where it migrates to the circulatory system and takes up residence in the pulmonary arteries and heart, growing and reproducing to an alarming degree. The effects on the dog are quite predictable, cardiac failure over a year or two, leading to death. Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and frequently does not succeed. Prevention is much the better course, via heartworm prophylactics which contain a compound which kills the larvae immediately upon infection without harming the dog. Often they are available combined with other parasite preventives.
  Many studies show the health benefits of dog ownership. Dogs not only provide comfort and companionship, but several studies have found that dogs decrease stress and promote relaxation. Dogs have positive impacts on nearly all life stages. They influence social, emotional, and cognitive development in children, promote an active lifestyle, and have even been able to detect oncoming epileptic seizures or the presence of certain cancers. But for all the positive benefits of keeping dogs, pet owners should be aware that dogs can carry germs that make people sick.

Histoplasmosis, caused by Histoplasma capsulatum, is a disease with a worldwide distribution. In the United States it is mainly found in the Mississippi and Ohio River areas, most commonly in bird and bat feces. Signs include weight loss, cough, fever, enlarged lymph nodes, and gastrointestinal symptoms.[11] Coccidioidomycosis, caused by Coccidioides immitis, is found in arid and semi-arid regions of Central and South America, Mexico, and southwestern United States. Signs include weight loss, fever, cough, enlarged lymph nodes, and lameness.[12][13]
This tick-borne illness is another highly preventable disease. It is caused by a bacteria transmitted by slow-feeding deer ticks that have been attached to the dog for at least 18 hours. It’s the most common of the tick-related illnesses.
Diabetes in dogs is a complex disease caused by either a lack of the hormone insulin or an inadequate response to insulin. After a dog eats, his digestive system breaks food into various components, including glucose—which is carried into his cells by insulin, a hormone secreted by the pancreas. When a dog does not produce insulin or cannot utilize it normally, his blood sugar levels elevate. The result is hyperglycemia, which, if left untreated, can cause many complicated health problems for a dog.

Pancreatitis*, or inflammation of the pancreas, is common in dogs. It is most commonly seen in middle-aged and older overweight dogs. Miniature Schnauzers are predisposed. Contributing factors include diabetes, hyperlipidemia, obesity, and dietary indiscretion. Signs include vomiting, diarrhea, abdominal pain, lethargy, and anorexia.[144]

Orthopedic diseases in dogs can be developmental, hereditary, traumatic, or degenerative. Because of the active nature of dogs, injuries happen frequently. One of the most common of these is an anterior cruciate ligament injury, a condition which often requires surgery. Bone fractures are a frequent occurrence in outdoor dogs due to trauma from being hit by cars. Degenerative joint disease is common in older dogs and is one of the most likely reasons for prescription of non-steroidal anti-inflammatory drugs.
Dog hookworms are tiny worms that can spread through contact with contaminated soil or sand. Dogs can also become infected with hookworms through accidentally ingesting the parasite from the environment or through their mother’s milk or colostrum. Young puppies are most often affected and might have dark, bloody stool and anemia. Severe infections in some puppies can lead to death.
Eye proptosis is a condition resulting in forward displacement and entrapment of the eye from behind by the eyelids. It is a common result of head trauma in dogs. Most commonly it occurs in brachycephalic (short nosed) breeds.[62]
Tapeworms* are also common and in the dog are usually Dipylidium caninum, which is spread by ingesting fleas and lice. Also common is Taenia pisiformis, spread by ingesting rabbits and rodents. Rare tapeworm infections are caused by species of the genera Echinococcus, Mesocestoides, and Spirometra. There are usually no symptoms.[6]
Ocular melanosis (OM) is a disease of the eye which in dogs is almost found exclusively in the Cairn Terrier. The disease is caused by an increase of melanocytes in the iris, sclera, and surrounding structures.[62]
A dog who is up to date with his vaccinations and who has been bitten by a possibly rabid animal should also be given a rabies booster vaccine immediately and kept under observation (length will vary depending on your state laws).

can dogs get skin cancer |

It is suspected the disease spreads from muddy and wooded areas – dog owners who do walk their dogs in these places are advised to wash off any mud as soon as possible, and of course, keep close control of their dogs at all times to monitor where they go.
The first sign of Alabama Rot is skin sores that have not been caused by a physical injury. These sores can present as lesions, swelling, a patch of red skin, or may be open and ulcer-like. The sores are most commonly found below the knee or elbow or occasionally on the stomach or face. Usually, this will cause localised hair loss and the dog will begin licking the wound. These lesions will be followed – between two and seven days later – with outward symptoms of kidney failure: reduced appetite, fatigue, and vomiting. 
Osteoarthritis*, also known as degenerative arthritis, is a common condition in dogs characterized by progressive deterioration of articular cartilage in the joints of the limbs. It can cause a great deal of pain and lameness. Treatment options include medications such as NSAIDs, corticosteroids, and joint fluid modifiers such as glycosaminoglycans. Other treatments include surgery, massage, warm compresses, chiropractic, and acupuncture.[35]
Hereditary orthopedic diseases are mainly found in purebred dogs. Hip dysplasia is a common problem that primarily affects larger breeds. Hip dysplasia is a defect in the shape of the hip joint which can, depending on the degree of hip luxation, be quite painful to the dog as it ages. Over time it often causes arthritis in the hips. Dysplasia can also occur in the elbow joint. Luxating patellas can be a problem for smaller breeds. It can cause lameness and pain in the hind legs.
There are topical medicines to repel and kill ticks you put directly on your dog’s fur, like Frontline and K9 Advantix. There are also pills, like NexGard, and even collars your dog can wear, like Preventic. Just keep in mind the effectiveness of topical medicines decreases through the month, especially if your dog goes swimming or has a bath. Year-round prevention is best.
Avoid bites and scratches from dogs. Dog bites might become seriously infected or might be a source of rabies. Be cautious with unfamiliar animals. Approach dogs with care, even if they seem friendly.
Infectious diseases that affect dogs are important not only from a veterinary standpoint, but also because of the risk to public health; an example of this is rabies. Genetic disorders also affect dogs, often due to selective breeding to produce individual dog breeds. Due to the popularity of both commercial and homemade dog foods, nutrition is also a heavily studied subject.
Although the name suggests otherwise, ringworm isn’t caused by a worm at all—but a fungus that can infect the skin, hair and nails. This highly contagious disease can lead to patchy areas of hair loss on a dog and can spread to other animals—and to humans, too.
Corneal dystrophy is a condition characterized by bilateral, noninflammatory opacity of the cornea. It appears as grayish white lines, circles, or clouding of the cornea. Corneal dystrophy can also have a crystalline appearance.[62]
Hypoadrenocorticism, also known as Addison’s disease, is a reduction of production of glucocorticoids and mineralocorticoids by the adrenal glands. There is more familiarity with the glucocortcoids, such as cortisol; mineralocorticoids control the amount of potassium, salt and water in the body.[106][107][108] It is most commonly caused by destruction of adrenal tissue, probably by autoimmune disease. Signs include increased drinking and urination, vomiting, diarrhea, collapse, shivering and weight loss; at times neither the causes nor symptoms are especially specific.[109][110] Because of this it is sometimes referred to as “the Great Mimic” or “the Great Imitator”.[107][111] It is possible not to see any symptoms of the disease until the adrenal cortex is 90% dysfunctional.[112] Addison’s can occur when regular steroid use is abruptly discontinued; during their use, the system the adrenal gland does not function at 100%. The system senses sufficient levels of these hormones in the body and does not signal for their production. Tapering the medication off gradually allows them to return to full production after discontinuation.[110][112] About 35% of affected dogs are not diagnosed until they experience an Addisonian crisis, which outwardly appears to be a “classic” shock and is a medical emergency.[105][112] Hyperkalemia[106] can develop and cause severe bradycardia. Only typical Addison’s patients have the risk of Addisonian crisis due to the lack of mineralocorticoids.[110] Treatment is with supplementation of mineralocorticoids in daily pills or a monthly injection. The atypical form and the form caused by abrupt withdrawal of steroids do not need mineralocorticoids.[110] Glucocorticoids are usually supplemented with oral prednisone.[113][114]
Retinal detachment* is caused in dogs by genetic disorders such as retinal dysplasia or Collie eye anomaly, trauma, inflammation or cancer. Reattachment may occur spontaneously or with medical or surgical therapy.[68]
Depending on the size of your pup, some health problems are more prevalent than others. For instance, big dogs tend to deal with more bone and joint problems, whereas smaller dogs tend to suffer more with organ and breathing disorders. Again, each breed is unique, but it is important to understand what common dog illnesses and health issues affect your pet. See below for the most common types of dog health issues and make sure to take immediate action if you think something serious is wrong with your dog.
Discoid lupus erythematosus is an uncommon autoimmune disease of the skin in dogs. It does not progress to systemic lupus erythematosus in dogs. The most common initial symptom is scaling and loss of pigment on the nose.[34]

Sensitivity to anaesthesia can occur in any breed, but sighthounds have been the breeds most documented to have anesthetic concerns. Sighthounds are known to have prolonged recovery times from ultra short-acting thiobarbiturates such as thiopental.[164]
Glomerulonephritis* is the presence of immune complexes in the glomerulus, resulting in leakage of protein into the urine. It can be caused by cancer, heartworm disease, pyometra, rickettsial infection, or systemic lupus erythematosus.[151] It can result in chronic kidney failure, hypoalbuminemia, which can cause ascites and peripheral edema, and nephrotic syndrome, which can cause hypertension or hypercoagulability.[152]
Pick up and dispose of dog stools, especially in areas where children might play. Cleaning up after your dog will help keep the area clean and reduce the risk of spreading disease to people or other animals.
Treating hot spots may involve shaving and cleaning the irritated area, antibiotics, anti-inflammatory drugs (NSAIDS), steroids, or topical medications, depending on how bad the hot spots are, and how much pain your pooch is in.
Foreign body is an object foreign to the body that becomes lodged in the gastrointestinal tract (or other part of the dog). Dogs are susceptible to gastrointestinal obstruction due to their ability to swallow relatively large objects and pass them through the esophagus. Foreign bodies most commonly become lodged in the stomach because of the inability to pass through the pyloric sphincter, and in the jejunum.

Cryptosporidium can cause profuse, watery diarrhea with cramping, abdominal pain, and nausea in both animals and people. Illness in people is usually self-limiting and lasts only 2-4 days, but can become severe in people with weakened immune systems.

Some dog owners opt for no treatment of the cancer, in which case palliative end of life care, including pain relief, should be considered. Regardless of how you proceed after a diagnosis of cancer in your pet, it is very important to consider his quality of life when making future decisions.
Brucellosis in dogs is caused by Brucella canis. It is a sexually transmitted disease, but can also be spread through contact with aborted fetuses. The most common sign is abortion during the last trimester or stillbirth. Other symptoms include inflammation of the intervertebral disc and eye (uveitis), and inflammation of the testicle (orchitis) and prostate (prostatitis) in males.[6]
Megaesophagus is a disease of the esophagus characterized by low motility and dilation. Most cases in adult dogs are idiopathic. It is the most common cause of regurgitation in dogs. Other causes of megaesophagus include myasthenia gravis, lead poisoning, and Addison’s disease.[141]
Scotty Cramp is a disease in Scottish Terriers causing spasms and hyperflexion and hyperextension of the legs. It is caused by a disorder in serotonin metabolism that causes a deficiency of available serotonin.[6]
For most dogs, insulin injections are necessary for adequate regulation of blood glucose. Once your pet’s individual insulin treatment is established, typically based on weight, you will be shown how to give him his insulin injections at home.
Ear infections are common in dogs, particularly breeds with hanging ears, such as Beagles, and dogs with narrow ear canals, such as Cocker Spaniels. Other predisposing factors include allergies, ear parasites, and hypothyroidism.[74]
My dog will all the sudden get a burst of energy and run so fast he can’t stop and he will run right into things. Now he does this exorcist thing with his head, turning it back violently, teeth chattering and trying to bite his ear kind of thing and will not let anyone near him at all. I think he is having seizures but I’m not sure. I need help. Anyone??
Malignant histiocytosis (histiocytic sarcoma) is an aggressive cancer found primarily in certain breeds including the Bernese Mountain Dog, rottweiler, golden retriever and flat coated retriever. It is characterized by infiltration of the joints, lungs, spleen, lymph nodes, and other organs by malignant histiocytes.[6]
Sporotrichosis is a fungal disease caused by Sporothrix schenckii that affects both dogs and humans. It is a rare disease in dogs, with cat and horse infections predominating in veterinary medicine. The disease in dogs is usually nodular skin lesions of the head and trunk.[22]
Brachycephalic airway obstructive syndrome is a condition of brachycephalic (short-nosed) dogs, characterized by the presence of stenotic nares, elongated soft palate, narrow trachea, collapsed larynx, and everted laryngeal saccules. Signs include difficult and noisy breathing. Surgical options are available.[185]
Patent ductus arteriosus* is one of the most common congenital heart defect in dogs around the world. It is inherited in toy and miniature Poodles, and seen commonly in German Shepherds, Pomeranians, Bichon Frises, and Malteses. Signs include a continuous heart murmur, bounding (strong) femoral pulse, tachypnea (increased breathing rate), dyspnea (labored breathing), and exercise intolerance.[49]
“Some will get secondary infections with bacteria. Some dogs can die but it’s pretty uncommon. That’s more likely in dogs that already have other diseases: respiratory disease, heart disease or other things that make them more likely to get a serious illness,” he said.

Cataracts* are an opacity in the lens of the eye. Most cataracts in dogs are caused by a genetic predisposition, but diabetes mellitus is also a common cause.[64] The only effective treatment is surgical removal.[65]
The most common form of the disease in dogs is Type I, insulin-dependent diabetes, which occurs when the pancreas is incapable of producing or secreting adequate levels of insulin. Dogs who have Type I diabetes require insulin therapy to survive.
“Chase has no known medical history, so everything was on the table, and that was a problem,” owner Scott Picken said. “It wasn’t until the fourth vet visit that a blasto test was done and by the time it came back positive, he was pretty sick.”
Mouse and rat poisons containing cholecalciferol cause hypercalcemia and hyperphosphatemia in dogs. Clinical signs include depression, loss of appetite, vomiting blood, weakness, and shock. Treatment is as above for recent exposure. When hypercalcemia occurs (which can take 1 to 2 weeks), treatment is with intravenous fluids (saline), diuretics, corticosteroids, and calcitonin. Long term prognosis is good once the dog is stabilized.
Diabetes in dogs is a complex disease caused by either a lack of the hormone insulin or an inadequate response to insulin. After a dog eats, his digestive system breaks food into various components, including glucose—which is carried into his cells by insulin, a hormone secreted by the pancreas. When a dog does not produce insulin or cannot utilize it normally, his blood sugar levels elevate. The result is hyperglycemia, which, if left untreated, can cause many complicated health problems for a dog.
