signs of lung cancer in dogs |

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.
experienced vet to execute the regular checkups in order to give your pet a healthy and comfortable life. In addition that, you should not change your dog’s diet without taking the permission of a skilled veterinarian.
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]
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]
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]
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]
Plasmacytomas* are common skin tumors in dogs that derive from B lymphocytes. Most are benign. Tumors of B lymphocyte origin that affect the bone marrow and are diffuse throughout the body are malignant and are called multiple myeloma*.[161]
Umbilical hernia* is a failure of the umbilical ring of the abdominal wall to close. They are very common and can be caused by genetics or by traction on the umbilical cord or by the cord being cut too close to the body. They are corrected by surgery.[160]
Cauda equina syndrome*, also known as degenerative lumbosacral stenosis, in dogs is a compression of the cauda equina by a narrowing of the lumbosacral vertebral canal. It is most commonly seen in German Shepherd Dogs. Signs include pain, weakness, and rear limb muscle atrophy.[59]
Part of your job as a dog owner will be protecting your family from the parasites that can plague dogs and make their lives (and yours) miserable. Fortunately, that’s much easier done these days than it once was.
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]
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).

8. Arthritis: Arthritis is often seen as a rite of passage for our older pets. They may seem slow to rise in the morning, or a bit reluctant to jump up to their favorite spot on the couch. Your veterinarian can diagnose most forms of arthritis during a routine exam, but they may also recommend an x-ray to rule out other issues or evaluate how seriously inflamed the joints are. While there is no cure for arthritis, there are joint supplements, and even treatments like acupuncture, to help keep your pet as mobile as possible for as long as possible.
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]
Our dogs are faithful companions, and they depend on us for good care. To help your canine friend live a healthy life, you should know some of the most common health problems dogs face, their signs, and what you can do about them.
“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.
Pick a dog that is bright, alert, and playful. Dogs and puppies should have shiny, soft fur that is free of stool. Signs of illness in a dog include appearing sluggish or depressed, having diarrhea, abnormal breathing, and fluid running from its eyes or nose. Make sure to take your new dog or puppy to the veterinarian within a few days to a week after adoption for a health visit.
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.
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]
Syringomyelia* is a condition where a fluid filled sac develops in the spinal cord. The most important cause in dogs is by a Chiari I malformation, which is when an underdeveloped occipital bone interferes with spinal fluid circulation and results in fluid accumulation in the cervical spinal cord. This is a congenital disease most commonly found in small breeds such as the Brussels Griffon and the Cavalier King Charles Spaniel. Other breeds known to be affected include the Bichon Frise, Boston terrier, bull terrier, Chihuahua, French bulldog, Havanese, King Charles spaniel (the English toy spaniel), Maltese, miniature dachshunds, miniature and toy poodles, Papillon, Pomeranian, Pugs, Shih Tzu, Staffordshire bull terrier, and the Yorkshire terrier. Signs may include ataxia, weakness, and neck pain.[55]
“Be aware of it and insist a blasto test be done early,” Picken says. “It’s a small price to pay to eliminate the possibility of a tragic outcome. I found the perfect rescue dog and was ecstatic about the thought of having so many good years with him. To go from that to the heartbreak of losing him so quickly is a pretty steep fall.”
“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 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.
Cor triatriatum*, specifically cor triatriatum dexter, occurs in dogs and is characterized by a fibrous division of the right atrium into two chambers, usually with a hole in between them. It results in right heart failure (ascites). It can be treated by balloon valvuloplasty or surgical resection.[52]
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]
Alabama rot dog disease is on the rise once again in the UK, but how big a threat is it to your dog? Here is our expert guide explaining what it is, how to spot the signs and what you can do to protect your dog from catching this deadly disease. 
Contact your veterinarian immediately if your dog shows any of the clinical signs mentioned on the list above. Should your dog receive a diagnosis of cancer, you may wish to consult a veterinary oncologist, often employed by specialty veterinary practices and teaching hospitals.
Thyroid cancer* is rare and usually nonproductive in dogs (unlike in cats, in which it causes hyperthyroidism). One-third of thyroid tumors are small benign adenomas; the rest are malignant carcinomas, usually large and invasive.[161]

“Anytime you’re out with your dog,” says Pat Miller, author of The Power of Positive Dog Training, “one of you is training the other.” Better for it to be you. Begin as early as 8 weeks, before it picks up bad behaviors, and continue even into old age to keep your dog sharp. Make training about reward, not punishment. (Old-school devices like choke collars injure and instill fear, Miller says, “the most common cause of canine aggression.”) When housebreaking, “keep your puppy under close supervision and take it outside more often than he needs to go,” says Miller. “Reward it when it goes to the bathroom so it learns that this is the right way to do it.” Tip: “A well-trained dog has more opportunities to improve its physical health,” Miller adds. Walks, fetch, and agility training are more fun for you both if your dog will come when called, wait when asked, and greet other people and pups politely.
How to treat: Again, assess the behavior leading up to the vomiting. If there was nothing unusual, then there’s probably no need to be concerned. If the vomiting is persistent, however, or you noticed your dog acting differently before the vomiting, there could be a number of things wrong and it’s best to take your dog to your vet to get him checked out.
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.
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.

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.
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]
My 13 yr old male miniature (24lb) neutered Dachshund has started to urinate when at rest. Usually at night, other than that he is acting normal & eating well. He does drink a lot but not really any more than what he has normally consumed before this all started. We are waiting for the results of his urinalysis. Any suggestions out there?
Physical elements of certain dog breeds also affect susceptibility of individuals to skin problems, such as wrinkled skin or excessive skin folds. For instance, skin-fold dermatitis is a skin infection more prevalent in breeds such as the bulldog, cocker spaniel, and English Springer spaniel.[17]

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]

  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.

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.
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.
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.
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.
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.
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?
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.
What’s true for humans is also true for dogs. Of-the-moment food regimens—like the wolf diet, raw-food craze, or grain-free eating—aren’t worth the money or time. Yes, they can provide balanced meals, and thus aren’t harmful, Case says, “but there is no demonstrated evidence of their health benefits” over other more-standard diets. Tip: Want to provide your pooch with raw food? Be sure it’s pasteurized to ensure safety.
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]
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.
Ectropion (eyelid folding outward) is a common condition in dogs, usually affecting the lower lid. Breeds associated with ectropion include the Cocker Spaniel, the St. Bernard, the Bloodhound, and the Basset Hound.[62]
“Food is one way we show our dogs love,” says Case, “so banning people from feeding their dogs extras doesn’t work.” Even so, just as you can’t afford the effects of too many snack sessions, neither can your pup. Limit food beyond what’s in your dog’s daily diet—including that tiny bit of leftover salmon from your plate and even training treats—to no more than 10% of its calorie need, Case says. Tip: Make training treats small enough so your dog can down them quickly and delicious enough that they’ll count as a real reward.

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.
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]
Between approximately 10 and 30 percent of dogs in the United States receive nutritional supplements.[66] A survey of U.S. pet owners in 2006 found that the most commonly used supplements were multivitamins and chondroprotective agents.[67]
Craniomandibular osteopathy is a hereditary disease in West Highland White Terriers and also occurs in other terrier breeds. It is a developmental disease in puppies causing extensive bony changes in the mandible and skull. Signs include pain upon opening the mouth.[40]

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]
“The concern among vets in the UK is that, unlike the Alabama Rot that affected greyhounds in America, the disease in the UK does not seem to target any specific breed, age, sex or weight of dog,” said Dr Huw Stacey, director of clinical services at Vets4Pets.
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
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]
Due to the indiscriminate nature of a dog’s appetite, gastrointestinal upset is a frequent occurrence in dogs. The most common symptoms are anorexia, vomiting, and diarrhea. Foreign body ingestion can lead to acute obstruction of the gastrointestinal tract, a very dangerous condition. Acute pancreatitis can also result from dietary indiscretion.

Dogs infected with parvovirus need intensive treatment in a veterinary hospital, where they will receive antibiotics to control secondary infections, drugs to control the vomiting, intravenous fluids to treat dehydration and other supportive therapies.
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]
Intussusception* is characterized by telescoping of one part of the gastrointestinal tract into another part, forming an obstruction. It is most common in dogs six to eight months old. Surgery is necessary for treatment.[147]

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]
If possible, contact the owner and ensure the animal has a current rabies vaccination. You will need the rabies vaccine license number, name of the veterinarian that administered the vaccine, and the owner’s name, address, and phone number.

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.
“The first sign that is normally seen is a skin sore that isn’t caused by a known injury. Most commonly these sores are found below the elbow or knee and appear as a distinct swelling, a patch of red skin or are open and ulcer-like.
Common treatments include surgery, chemotherapy, radiation and immunotherapy or a combination of therapies. Success of treatment depends on the type and extent of the cancer and the aggressiveness of the therapy. Of course, early detection is best.
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.
“While there is currently no known way to prevent a dog from contracting the disease, there is a very useful guide available online to help people understand where in the UK confirmed cases have been found and advice on how to spot signs.
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.
Treat your dog to prevent fleas, ticks, heart worm, and other ickies from making your dog their home, says Kerns. The health effects of infestation are far worse than pesticide side effects. That said, don’t overdo it, she warns. “Use what’s absolutely necessary for your environment,” rather than mindlessly dosing your dog every month against pests it’s not like to encounter. Tip: You can check the prevalence of pests in your area at capcvet.org.
Sudden acquired retinal degeneration (SARD) is a disease in dogs causing sudden blindness. It can occur in any breed. The cause is unknown, but possibly involves either autoimmune disease, a toxin, or Cushing’s disease. Symptoms include sudden permanent blindness, dilated pupils, and loss of the pupillary light reflex.[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]

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.
It is important, however, not to get overly worried by this as the percentage of dogs in the UK who have contracted this disease is truly minuscule. Though, what is vital, is that you understand the problem and know what to look out for, should your dog come into contact with it, as time plays a large part in successfully treating the disease.
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.

Every diabetic dog is an individual and will respond differently to therapy. Diabetes treatment is based on how severe the signs of disease are and whether there are any other health issues that could complicate therapy.
People become infected with dog hookworms while walking barefoot, kneeling, or sitting on ground contaminated with stool of infected animals. Hookworm larvae enter the top layers of skin and cause an itchy reaction called cutaneous larva migrans. A red squiggly line might appear where the larvae have migrated under the skin. Symptoms usually resolve without medical treatment in 4-6 weeks.
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.
“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.

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]
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).
No two dogs are alike. Likewise, no two dog breeds are alike, especially when it comes to their health. Dog health problems range from infections to cancers, and it’s up to the pet parents to keep their companions happy and healthy by understanding some common dog illnesses and diseases.
“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.
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]
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.
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.

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.
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.
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]
Being familiar with these common dog health issues should help you know which ones you can treat yourself, and when it’s time to see a vet. If you find yourself visiting the vet often perhaps pet insurance is something you should consider. It can greatly reduce your out-of-pocket cost when visiting your veterinarian. Check out our Pet Insurance Comparison to see which pet insurance providers might be a good fit for your family.
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.
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]
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.
Rabies, a fatal neurologic disease in animals and people, is caused by a virus. Animals and people are most commonly infected through bites from rabid animals. Infected dogs might have a variety of signs, but most often have a sudden behavioral change and progressive paralysis. Rabies is prevented by vaccination.
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.

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]

Heat stroke can occur in dogs, especially in flat-faced breeds such as the Bulldog or in giant breeds. Breed, lack of water, exercise, and high ambient temperature predispose dogs to heat stroke. Signs include vomiting, diarrhea, collapse, difficulty breathing, and body temperature approaching 42 °C to 43 °C. Treatment includes cooling the dogs with wet towels and fans, intravenous fluid therapy, and other supportive care.[165] If a dog’s temperature begin to drop to around 40 °C, stop the cooling process. Once a dog’s body begins to cool, it can drop quickly and getting them too cool can create different problems. Allow the dog only a couple of laps of water until their temperature begins to drop to a more normal level. Do not allow a dog to gulp large quantities of water. If a dog is panting excessively and then drinks a lot of water, he will swallow large amounts of air with the water and this can cause an equally life-threatening case of gastric dilatation volvulus (bloat) in their stomach.[166]
Urinary incontinence* is leakage of urine, usually due to incompetence of the urethral sphincter in adult dogs and ectopic ureter (a congenital condition in which the ureter enters the urinary tract posterior to the urethral sphincter) in puppies. In adult dogs it is most commonly seen in large spayed females. The lack of estrogens in spayed dogs has been linked to development of incontinence. Replacement of estrogens, phenylpropanolamine, and surgery have all been used for treatment.[156]
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]
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]
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.

Cushing’s syndrome, also known as hyperadrenocorticism, is characterized by an increase in glucocorticoids secreted by the adrenal glands. About 85 percent of cases are caused by a tumor in the pituitary gland, while 15 percent are caused by an adrenal tumor. The pituitary gland produces a hormone that signals the adrenal gland to produce cortisol; a tumor can cause it to produce the adrenal-stimulating hormone even when it is not needed.[115][116] Signs include increased appetite, increased drinking and urination, a pot-bellied appearance, muscle weakness, and lethargy.[115] Cushing’s can be caused by overuse of steroid medications; in some cases, stopping the medication is enough to solve the problem.[115] Diagnosis can be difficult as there are no tests with both high sensitivity and specificity.[117] Treatments inclulde mitotane, trilostane,[118][119] ketoconazole, or selegiline.[120][121] Surgery is used in some cases of adrenal tumors.[122]
Wash your hands with soap and running water after contact with dogs, dog saliva, or dog stool. Be sure to assist children with handwashing. Thoroughly washing hands will reduce the risk of disease transmission to people.
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]
Demodicosis, also known as demodectic mange, is caused by Demodex canis mites which live in small numbers in sebaceous glands and hair follicles. These mites can cause inflammation and hair loss, and may also lead to secondary bacterial infections such as fever, lethargy, and enlarged lymph nodes.
The virus attacks rapidly-dividing cells in a dog’s body, most severely affecting the intestinal tract. Parvovirus also attacks the white blood cells, and when young animals are infected, the virus can damage the heart muscle and cause lifelong cardiac problems.
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]
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]
Lead poisoning* is uncommon in dogs. Exposure to lead is from eating paint chips from lead-based paint (found in houses painted prior to 1950), and eating lead objects such as shot, fishing sinkers, or counterweights. Signs of poisoning include vomiting, diarrhea, blindness, seizures, and tremors.[168]
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]

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.
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]
Degenerative (myxomatous) mitral valve disease* is a common cause of congestive heart failure in dogs, especially small, older dogs.[48] The leaflets of the valve become thickened and nodular, leading to mitral valve regurgitation and volume overload of the left side of the heart. Cavalier King Charles Spaniels and Dachshunds have an inherited form of this disease.[49]

If possible, contact the owner and ensure the animal has a current rabies vaccination. You will need the rabies vaccine license number, name of the veterinarian that administered the vaccine, and the owner’s name, address, and phone number.
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]
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.
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]

Back pain* in dogs, particularly in long-backed breeds, such as Basset Hounds and Dachshunds, is usually caused by intervertebral disk disease. It is caused by degeneration and protrusion of the disk and compression of the spinal cord. It occurs most commonly in the cervical and thoracolumbar regions. Signs include back pain, hind limb weakness, and paralysis.[39]
Be aware that dogs might shed Campylobacter, Giardia, hookworms, roundworms, and other germs in their stool. Plan to clean up after your pet frequently. Wash your and your child’s hands thoroughly with soap and water after feeding or cleaning up behind dogs.

Primary ciliary dyskinesia* is a dysfunction of cilia, which manifests as sperm immotility and respiratory disease. Signs include nasal discharge, recurring pneumonia, and infertility. Symptoms develop soon after birth.[177]
Thrombocytopenia* is a common condition in dogs characterized by low platelet counts. Platelets are used in clotting the blood, so dogs with this condition may have spontaneous bleeding or prolonged bleeding following surgery, injury, or during an estrous cycle. Causes include some rickettsial infections such as ehrlichiosis, cancers such as hemangiosarcoma, or immune-mediated disease.[43]
Salmon poisoning disease is a fatal disease caused by infection with a rickettsia, either Neorickettsia helminthoeca or Neorickettsia elokominica. Dogs are infected by eating raw salmon from the Pacific Northwest.[6]
Obesity is an increasingly common problem in dogs in Western countries. As with humans, obesity can cause numerous health problems in dogs (although dogs are much less susceptible to the common cardiac and arterial consequences of obesity than humans are). According to a study published in the Journal of Veterinary Internal Medicine, the prevalence of obesity in dogs is between 22 and 40 percent.[61]
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 is showing any abnormal clinical signs as listed above, make an appointment to see your veterinarian immediately. If a diabetic dog is not treated, he can develop secondary health problems like cataracts and severe urinary tract problems. Ultimately, untreated diabetes can cause coma and death.

Newborn puppies receive antibodies from their mothers that help provide immunity, but immunity to CPV wears off before the puppies’ immune systems are developed enough to destroy the virus and fight off infection.
Coccidioidomycosis* is a fungal disease caused by Coccidioides immitis or Coccidioides posadasii that affects a variety of species, including dogs. In dogs signs of primary pulmonary disease include a cough, fever, weight loss, anorexia, and lethargy. Disseminated disease occurs when the fungus has spread outside of the lungs and may include clinical signs such as lameness, pain, seizures, anterior uveitis, and localized swelling.[17] Diagnosis of Valley Fever may include multiple tests, including serology and radiology. According to a study performed in the Tucson and Phoenix area, 28% of dogs will test positive for exposure to the fungus by two years of age, but only 6% of the dogs will be ill with clinical disease.[18] There is an increased risk of infection associated with amount of time spent outdoors, a larger roaming space accessed by the dog, and increasing age.[19]
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.
There are all types of canine cancers, and they seem to be on the rise. A staggering 50 percent of dogs aged ten and older will develop some form of cancer, and it’s the leading cause of death of dogs in this age group.
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.
The risk for contracting rabies runs highest if your dog is exposed to wild animals. Outbreaks can occur in populations of wild animals (most often raccoons, bats, skunks and foxes in this country) or in areas where there are significant numbers of unvaccinated, free-roaming dogs and cats.
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.
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.
Cauda equina syndrome*, also known as degenerative lumbosacral stenosis, in dogs is a compression of the cauda equina by a narrowing of the lumbosacral vertebral canal. It is most commonly seen in German Shepherd Dogs. Signs include pain, weakness, and rear limb muscle atrophy.[59]
7. Flea and tick borne diseases: Fleas and ticks are certainly undesirable guests on your pets fur, but they are more than just unwelcome creepy crawlies. These tiny passengers can carry serious diseases that can cause profound illness in both pets and people. Want to keep your cats, dogs, and human family healthy? Use a monthly topical flea and tick preventative, vacuum regularly, and always check your pets and yourself after playing with other animals or in grassy fields.
Tetanus* is a disease caused by the bacteria Clostridium tetani following wound contamination. Dogs are not very susceptible to tetanus. Signs include difficulty opening the mouth and eating, contraction of the facial muscles, and rigid extension of the limbs. Dogs may also get localized tetanus, signs of which include stiffness of a limb spreading to the rest of the body.[183]

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]
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]
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.

Due to the indiscriminate nature of a dog’s appetite, gastrointestinal upset is a frequent occurrence in dogs. The most common symptoms are anorexia, vomiting, and diarrhea. Foreign body ingestion can lead to acute obstruction of the gastrointestinal tract, a very dangerous condition. Acute pancreatitis can also result from dietary indiscretion.
What to look for: The signs of obesity might seem obvious, but having regular weight checks is important in order to keep records of your dog’s weight over time. It is important to recognize your dog’s weight gain early to give him the best chance possible for recourse.
Inflammatory bowel disease (IBD)* is a group of diseases in dogs that are idiopathic and characterized by the presence of inflammatory cell infiltrates in the stomach and/or intestinal walls. It is a common condition. Signs include vomiting, diarrhea, and weight loss. Treatment is with dietary modification and use of medications such as corticosteroids, metronidazole, sulfasalazine, and azathioprine.[145]
People become infected with dog hookworms while walking barefoot, kneeling, or sitting on ground contaminated with stool of infected animals. Hookworm larvae enter the top layers of skin and cause an itchy reaction called cutaneous larva migrans. A red squiggly line might appear where the larvae have migrated under the skin. Symptoms usually resolve without medical treatment in 4-6 weeks.
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.
Be aware that dogs might shed Campylobacter, Giardia, hookworms, roundworms, and other germs in their stool. Plan to clean up after your pet frequently. Wash your and your child’s hands thoroughly with soap and water after feeding or cleaning up behind dogs.
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.

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]
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]
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]
Hemolytic anemia* is a type of regenerative anemia found in dogs characterized by destruction of the red blood cell. The most important type is immune-mediated hemolytic anemia, which can be a primary disease or secondary to cancer, infection, drugs, or vaccinations. Antibodies are present on the cell surface, leading to lysis and severe anemia. Other causes of hemolytic lesion include hypophosphatemia, exposure to toxins such as lead, infections such as ehrlichiosis or babesiosis, and rarely, neonatal isoerythrolysis.[45] The behavioral condition pica, especially when involving the eating of concrete dust, tile grout, or sand, may be a sign of hemolytic anemia, indicating the need for a complete blood count to investigate a possible diagnosis.[46][47]
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]

Physical elements of certain dog breeds also affect susceptibility of individuals to skin problems, such as wrinkled skin or excessive skin folds. For instance, skin-fold dermatitis is a skin infection more prevalent in breeds such as the bulldog, cocker spaniel, and English Springer spaniel.[17]
Because infection can potentially spread over a dog’s body and infect other animals and people, it is important that you see your vet for an accurate diagnosis if your pet is showing any signs of a skin problem.

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.
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.
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.
Dilated cardiomyopathy (DCM) is a disease of heart muscle resulting in decreased myocardial contractility. The left ventricle compensates for this disease by growing larger (eccentric or volume overload hypertrophy; AKA dilation). The left atrial is also dilated when the disease is severe. It is seen in large/giant dog breeds such as Boxers, Great Danes, and Doberman Pinschers. It is usually idiopathic, but can also be caused by taurine deficiency in American Cocker Spaniels or doxorubicin use. A mutation in the gene that encodes for pyruvate dehydrogenase kinase 4 is associated with DCM in Doberman Pinschers in the USA.[50] Dilated cardiomyopathy usually ultimately results in congestive heart failure. Atrial fibrillation is common in giant breed dogs with DCM. Doberman Pinschers more commonly have ventricular arrhythmias (e.g., premature ventricular complexes; ventricular tachycardia) that predispose them to sudden death (i.e., ventricular fibrillation).[49]

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]
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]
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]
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.
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.
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]
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.
Thrombocytosis* is a condition characterized by an excess of platelets. Most cases are physiologic (caused by exercise) or reactive (secondary to some cancers, blood loss, or certain drugs). Rarely the condition is caused by a primary bone marrow disorder. In this last case, the platelets may not function normally, causing the blood to not clot properly.[44]
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).
Laboratory tests include blood tests (e.g., to detect a low white blood cell count) and other tests to detect the virus (e.g., ELISA, electron microscopy). ELISA (enzyme-linked immunosorbent assay), which detects the presence of the virus in stool, is used most often. In some cases, recent immunization with the live virus can produce a false positive test result.
What to look for: Since kennel cough is a respiratory infection, it can be easily transmitted from one dog to another when they interact. Look for lethargy, coughing, leaky nose and eyes or loss of appetite as common signs that your dog might have kennel cough.
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]
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]
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.
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.
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]

Cocoa within chocolate contains theobromine,[34] a chemical stimulant that, together with caffeine and theophylline, belongs to the group of methylxanthine alkaloids. Dogs are unable to metabolize theobromine effectively. If they eat chocolate, the theobromine can remain in their bloodstreams for days, and dogs may experience fast heart rate, severe diarrhea, epileptic seizures, heart attacks, internal bleeding, and eventually death.[35] “One ounce of milk chocolate per pound of body weight is a potentially lethal dose in dogs.”[36] In case of accidental intake of chocolate by especially a smaller dog, contact a veterinarian or animal poison control immediately; it is commonly recommended to induce vomiting within two hours of ingestion. If chocolate ingestion is suspected (mostly dark or baking chocolate), hydrogen peroxide can be used to safely induce vomiting, then making a trip to the veterinarian is suggested. Large breeds are less susceptible to chocolate poisoning, but can still die after eating four ounces[37] of chocolate.
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]
Hypothyroidism is the most common endocrine disease in dogs. It can be caused by autoimmune destruction (lymphocytic thyroiditis) or idiopathic atrophy of the thyroid gland.[99] These two causes are responsible for over 95% of the hypothyroidism cases in dogs.[100] Signs include decreased appetite, weight gain, hair loss, dry skin/coat, skin that is cold to the touch, recurring skin infections, and lethargy. The dog may also seek out warm places to lie. The symptoms of hypothyroidism are shared with many other medical conditions; it may not be the first thought when a diagnosis is made.[101] Symptoms may not appear until 75% or more of the gland is non-functional. In less than 10% of hypothyroidism cases, the problem is not with the thyroid gland itself, but with the pituitary gland in the brain. The pituitary gland produces a thyroid stimulating hormone (TSH);[102] without this hormone to signal the thyroid gland to produce its thyroid hormone, the thyroid gland remains inactive.[100] Treatment is with oral thyroid hormone supplementation.[103][104] Lack of enough iodine in the diet can produce a form of hypothyroidism; without the proper amount of it, the thyroid gland fails to produce enough thyroid hormone.[100] Myxedema coma is a rare but serious aspect of the disease that is a medical emergency.[105]

Tracheal collapse is characterized by incomplete formation or weakening of the cartilagenous rings of the trachea. It is most common in small and toy breeds. Signs include a cough (often called a “goose honk cough” due to its sound), especially when excited.[6]
“Anytime you’re out with your dog,” says Pat Miller, author of The Power of Positive Dog Training, “one of you is training the other.” Better for it to be you. Begin as early as 8 weeks, before it picks up bad behaviors, and continue even into old age to keep your dog sharp. Make training about reward, not punishment. (Old-school devices like choke collars injure and instill fear, Miller says, “the most common cause of canine aggression.”) When housebreaking, “keep your puppy under close supervision and take it outside more often than he needs to go,” says Miller. “Reward it when it goes to the bathroom so it learns that this is the right way to do it.” Tip: “A well-trained dog has more opportunities to improve its physical health,” Miller adds. Walks, fetch, and agility training are more fun for you both if your dog will come when called, wait when asked, and greet other people and pups politely.

Vaccine reactions are adverse events which occur following vaccination, including granuloma formation, but most commonly the term vaccine reaction is used to describe a type I hypersensitivity reaction. The most common signs are facial swelling and hives, but more rarely very serious signs such as hypotension and collapse may occur.[180]

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.
Atrial septal defect* is a hole in the division between the heart atria (upper chambers of the heart). It is an uncommon abnormality in dogs. Most are not clinically significant, but large defects can cause right heart failure and exercise intolerance. Standard Poodles are the most common breed diagnosed with ASD in the USA.[49]

MRSA can be transmitted back and forth between people and animals through direct contact. In people, MRSA most often causes skin infections that can range from mild to severe. If left untreated, MRSA can spread to the bloodstream or lungs and cause life-threatening infections.
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]
Thyroid cancer* is rare and usually nonproductive in dogs (unlike in cats, in which it causes hyperthyroidism). One-third of thyroid tumors are small benign adenomas; the rest are malignant carcinomas, usually large and invasive.[161]
It’s not uncommon to find your dog eating feces. Some consume their own or other dogs’ feces; others seem to prefer cat feces (which, due to the feline digestive system,[65] are high in protein and consumed by many animals in the wild) This can be harmful if the feces has any pathogens or parasites or contain excreted drugs.

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.

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.
Coccidioidomycosis* is a fungal disease caused by Coccidioides immitis or Coccidioides posadasii that affects a variety of species, including dogs. In dogs signs of primary pulmonary disease include a cough, fever, weight loss, anorexia, and lethargy. Disseminated disease occurs when the fungus has spread outside of the lungs and may include clinical signs such as lameness, pain, seizures, anterior uveitis, and localized swelling.[17] Diagnosis of Valley Fever may include multiple tests, including serology and radiology. According to a study performed in the Tucson and Phoenix area, 28% of dogs will test positive for exposure to the fungus by two years of age, but only 6% of the dogs will be ill with clinical disease.[18] There is an increased risk of infection associated with amount of time spent outdoors, a larger roaming space accessed by the dog, and increasing age.[19]
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]
Leukemias* are progressive proliferation of cancerous white blood cells within the bone marrow, resulting in destruction of the bone marrow and pancytopenia in many cases. Types of leukemia in dogs include acute lymphoblastic leukemia, acute myelocytic leukemia, acute monocytic leukemia, acute myelomonocytic leukemia, acute megakaryocytic leukemia, chronic lymphocytic leukemia, chronic myelogenous leukemia, chronic basophilic leukemia, and chronic eosinophilic leukemia (or hypereosinophilic syndrome).[161]
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]
Ringworm infections in people can appear on almost any area of the body. These infections are usually itchy. Redness, scaling, cracking of the skin, or a ring-shaped rash may occur. If the infection involves the scalp or beard, hair may fall out. Infected nails become discolored or thick and may possibly crumble.
It takes just three weeks for one flea to turn into an infestation of 1,000 biting bugs. A very common canine health problem, fleas are easy for your dog to pick up, but they’re also easy to treat. Signs your dog may have fleas include:

So you’ve just adopted your puppy. There is a lot for both of you to learn in those first few weeks and a few basic things you need to do to make sure your puppy stays healthy and to protect your family from catching any nasties from your puppy.
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.
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.
Antifreeze (ethylene glycol), due to its sweet taste, poses an extreme danger of poisoning to dogs and cats if ingested. Even a very small amount such as a tablespoon can easily prove fatal. The antifreeze itself is not toxic, but is metabolized via the liver to the toxins glycolate and oxalate, which cause intoxication and vomiting, metabolic acidosis, and finally acute kidney failure leading to seizures and death. By the time clinical signs are observed, the kidneys are usually too damaged for the dog to survive so acting quickly is important. Immediate treatments include inducing vomiting by using apomorphine or dilute hydrogen peroxide solution (if this can be done shortly after ingestion), but these merely reduce the amount absorbed – immediate veterinary treatment is still usually imperative due to the high toxicity of the compound. Medical treatments may include fomepizole (preferred treatment) which competes favorably with the toxin in the body, ethanol which competes favorably in the liver long enough to allow excretion to take place, activated charcoal to further reduce uptake of undigested product, and hemodialysis to remove toxins from the blood. Dogs should not be allowed access to any place in which an antifreeze leak or spill has happened until the spill is completely cleaned out. Some brands of antifreeze contain propylene glycol instead of ethylene glycol and are marketed as being less harmful or less attractive to animals.
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]
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.
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.

Although Echinococcus invades many different organs of the body, most people who are infected with the disease will not have any signs of illness for years. Symptoms start when the slow-growing cysts become large enough to press on the organs they have invaded. The tapeworms grow slowly in several different organs of the body, most commonly the liver and lungs.
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.
Common treatments include surgery, chemotherapy, radiation and immunotherapy or a combination of therapies. Success of treatment depends on the type and extent of the cancer and the aggressiveness of the therapy. Of course, early detection is best.
“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.
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.

Sick sinus syndrome* is most commonly seen in female Miniature Schnauzers. It is characterized by sinoatrial node dysfunction and may include atrioventricular node disease and bundle branch block. Electrocardiogram findings include sinus bradycardia, sinus arrest, sinoatrial heart block, and atrial tachycardia. The major clinical sign is fainting (syncope).[49]

Conjunctivitis* is inflammation of the conjunctiva. In dogs it is most commonly caused by mechanical irritation (such as by entropion, ectropion, or trichiasis), allergies, and keratoconjunctivitis sicca. Any bacterial infection is usually secondary.[70]
  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.

Older, small breeds of dogs are prone to congestive heart failure due to degeneration of the mitral valve. This condition is known to be inherited in Cavalier King Charles Spaniels. Degenerative valve disease is the most common form of heart disease in dogs.[23] Mitral insufficiency leads to turbulent blood flow and increased pressure in the left atrium. This causes increased pressure in the pulmonary blood vessels and pulmonary edema (a build-up of fluid in the lungs). Decreased output of blood by the left ventricle causes the body to compensate by increasing sympathetic tone and activating the renin–angiotensin–aldosterone system (RAAS). Increased sympathetic tone leads to increased peripheral vascular resistance and increased heart rate and contractility of the heart muscle. Chronic elevation of sympathetic tone damages the heart muscle. Activation of the RAAS results in increased retention of water and sodium by the kidneys, vasoconstriction, and other effects that result in increased blood volume. It also results in an increase in diastolic pressure and leads to pulmonary edema. Treatment for congestive heart failure has historically focussed on two types of drugs that address these concerns: diuretics (especially furosemide), which decrease blood volume, and ACE inhibitors, which interrupt the RAAS. Recently, pimobendan – which increases the force with which the heart muscle contracts, and is also a vasodilator – is being more widely used in the treatment of congestive heart failure caused by valvular disease. A major veterinary study, called the QUEST study (QUality of life and Extension of Survival Time), published in September 2008 found that dogs with congestive heart failure receiving pimobendan plus furosemide had significantly better survival outcomes than those receiving benazepril (an ACE inhibitor) plus furosemide.[24] However, ACE inhibitors and pimobendan have different mechanisms of action, and many veterinary cardiologists recommend they be used concurrently. Within the past decade, a new surgical technique has been developed for mitral valve repair that replaces or strengthens the mitral valve chords with polytetrafluoroethylene (PTFE) prostheses and tightens the mitral valve ring to reduce or eliminate regurgitation.[25][26][27][28]
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.
Newborn puppies receive antibodies from their mothers that help provide immunity, but immunity to CPV wears off before the puppies’ immune systems are developed enough to destroy the virus and fight off infection.
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]
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]
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]
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.
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]
To avoid acute kidney disease, keep human medications away from your dog, unless advised otherwise by your vet. Also, keep antifreeze away from dogs; they like the taste but it’s quite poisonous, even in low doses. There are various ways dogs can get their paws on antifreeze, including licking it off the garage floor or getting it from winterized pipes.
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]
Some fungi are worse than others; there are diseases that only affect the skin and there are diseases that affect the entire body – the liver, lungs, and brain. The latter is much worse and can be deadly.

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]
4. Parvovirus: Commonly called “parvo,” this virus is terribly common in parts of the country with low vaccination rates and can be seen in cats and dogs (although the disease cannot be spread cross-species). Parvo is most frequently seen in puppies and kittens who have not yet been vaccinated. The mortality rate depends on how quickly the symptomsare caught by the owner and addressed by a veterinarian and the strength of a pet’s immune system. Most survivors of parvovirus do not harbor long-term effects.

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]

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.
Ocular tumors* in dogs are found in the eyelid, conjunctiva, third eyelid, cornea, sclera, iris, ciliary body, retina, choroid, optic nerve, and orbit. The most common types are Meibomian gland adenoma (eyelid), papilloma (eyelid), melanoma (eyelid, conjunctiva, sclera, iris, ciliary body, choroid), squamous cell carcinoma (conjunctiva), adenoma (ciliary body), adenocarcinoma (ciliary body), lymphoma (retina, choroid, ciliary body), medulloepithelioma (retina, choroid), ganglioglioma (retina, choroid), osteosarcoma (orbit), mast cell tumor (orbit), and optic nerve sheath meningioma.[161]
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]
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]
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.

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]
Pulmonic stenosis* is a congenital heart disease in dogs characterized by right ventricular outflow tract obstruction. Most commonly the narrowing occurs at the pulmonary valve but it can also occur below the valve (subvalvular) or above the valve (supravalvular). The most commonly affected breeds include terriers, Bulldogs, Miniature Schnauzers, Chihuahuas, Samoyeds, Beagles, Keeshonds, Mastiffs, and Bullmastiffs. Signs may include exercise intolerance, but often there is only a heart murmur.[49]
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]

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:
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]

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.

My dog was having seizures quite regularly, I had been to vets and they did not have answers. This is my empty nest child. So we constantly were changing his diet, I prayed about his health constantly and one day my husband and I were talking about it and it was like a light bulb went off in my head. STOP THE DAIRY! I used to feed him cheese like it was good for him. We have stopped the dairy for over a month and he hasn’t had a seizure since. I know this probably isn’t the answer for all fur babies but it was for mine and it changed his life.
Sudden acquired retinal degeneration (SARD) is a disease in dogs causing sudden blindness. It can occur in any breed. The cause is unknown, but possibly involves either autoimmune disease, a toxin, or Cushing’s disease. Symptoms include sudden permanent blindness, dilated pupils, and loss of the pupillary light reflex.[62]
This list of dog diseases is a selection of diseases and other conditions found in the dog. Some of these diseases are unique to dogs or closely related species, while others are found in other animals, including humans. Not all of the articles listed here contain information specific to dogs. Articles with non-dog information are marked with an asterisk (*).
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]
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.

How to treat: Again, assess the behavior leading up to the vomiting. If there was nothing unusual, then there’s probably no need to be concerned. If the vomiting is persistent, however, or you noticed your dog acting differently before the vomiting, there could be a number of things wrong and it’s best to take your dog to your vet to get him checked out.
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.
Kennel cough is an infectious respiratory disease which can be caused by one of several viruses or by Bordetella bronchiseptica. It most commonly occurs in dogs in close confinement such as kennels.[14]
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]
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!
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]
Cases of the mystery illness have been confirmed in at least 27 counties in England and Wales since 2012, with 14 cases confirmed in 2016 alone (to end April) and possibly two further unconfirmed cases in Scotland and Northern Ireland – the first   in these two countries

What to look for: Thankfully, rabies is not as common today as it once was due to the development of vaccinations, but it is still possible for your dog to become infected with rabies even if he has received his shots. Symptoms of rabies include heavy, thick drool and aggressive behavior.
Learn to watch your dog closely, and you’ll be surprised by how much it communicates how it feels, mentally and physically. The position of its ears and tail, it’s breathing, whether it often scratches or licks its paws can all be signs of distress. “Chronic behaviors and symptoms must be addressed,” says Kerns. “Healthy dogs don’t show symptoms on a daily basis.” Tip: Consider starting a health notebook or a calendar, so you can track when you administer meds, change food, or notice new behaviors, like obsessive grooming.
Alabama rot dog disease is on the rise once again in the UK, but how big a threat is it to your dog? Here is our expert guide explaining what it is, how to spot the signs and what you can do to protect your dog from catching this deadly disease. 
Complications include dehydration, secondary infections, sepsis and a condition in which part of the intestine slips into the part below it (called intussusception). CPV also can damage the spleen. Dogs that have another health condition are at increased risk for developing severe complications and illness.
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]
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]
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.

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.
Between approximately 10 and 30 percent of dogs in the United States receive nutritional supplements.[66] A survey of U.S. pet owners in 2006 found that the most commonly used supplements were multivitamins and chondroprotective agents.[67]
Cardiomyopathy, or disease of the heart muscle, is also seen in dogs and is associated with large breeds (the exception being Cocker Spaniels, a medium-sized breed). Dilated cardiomyopathy is seen in Great Danes, Irish Wolfhounds, St. Bernards, Dobermanns, Boxers, and other large breeds. Dobermanns, in addition to heart muscle failure, are prone to ventricular arrhythmias. Boxer dogs are predisposed to a unique cardiomyopathy with clinical and histological changes analogous to human arrhythmogenic right ventricular cardiomyopathy (ARVC).[29] The disease has been termed “Boxer cardiomyopathy” or “Boxer ARVC”, and is characterized by development of ventricular tachyarrhythmias.[30] Affected dogs are at risk of syncope and sudden cardiac death.[29] Myocardial failure and congestive heart failure are rare manifestations of this disease.[30]
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]
How to treat: First, determine what the allergen is. Common allergies can be treated by changing your dog’s food or the shampoo you use when bathing. Seasonal or environmental allergies can be treated with medications, but those will eventually weaken the immune system if administered repeatedly.
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.
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]
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]
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]

Dilated cardiomyopathy (DCM) is a disease of heart muscle resulting in decreased myocardial contractility. The left ventricle compensates for this disease by growing larger (eccentric or volume overload hypertrophy; AKA dilation). The left atrial is also dilated when the disease is severe. It is seen in large/giant dog breeds such as Boxers, Great Danes, and Doberman Pinschers. It is usually idiopathic, but can also be caused by taurine deficiency in American Cocker Spaniels or doxorubicin use. A mutation in the gene that encodes for pyruvate dehydrogenase kinase 4 is associated with DCM in Doberman Pinschers in the USA.[50] Dilated cardiomyopathy usually ultimately results in congestive heart failure. Atrial fibrillation is common in giant breed dogs with DCM. Doberman Pinschers more commonly have ventricular arrhythmias (e.g., premature ventricular complexes; ventricular tachycardia) that predispose them to sudden death (i.e., ventricular fibrillation).[49]
Complications include dehydration, secondary infections, sepsis and a condition in which part of the intestine slips into the part below it (called intussusception). CPV also can damage the spleen. Dogs that have another health condition are at increased risk for developing severe complications and illness.

Consider fencing in your yard rather than tying your dog outside. A fence will not only give your pet room to play, but also will protect it from wild animals and reduce the risk of strangers interacting with your dog. Several studies have shown that dogs on a chain are more likely to bite than those in a fenced yard.
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.

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.
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]
Other diseases affecting dogs include endocrine diseases, immune-mediated diseases, and reproductive diseases. Diabetes mellitus, Cushing’s syndrome, Addison’s disease, and hypothyroidism are the most common endocrine diseases. Immune-mediated hemolytic anemia is a devastating disease that causes severe anemia in dogs through destruction by the immune system. It has been associated with vaccinations and certain drugs, although many cases are idiopathic. A similar but less severe immune disease is immune-mediated thrombocytopenia, characterized by destruction of platelets by the immune system. Clinical signs include bruising and petechiae (pinpoint bruising, often seen in the mouth). Common reproductive diseases include pyometra (distension of the uterus with pus), mammary tumors, and benign prostatic hyperplasia.
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.
Sarcoptic mange is a parasitic skin disease that is caused by a tiny mite. Mange is transmitted between animals through close contact. In dogs, the mite causes severe itching and self-inflicted wounds from scratching.
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]
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]
