symptoms of lyme disease in dogs |

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]

Vaccinating your dog doesn’t just protect him from rabies—it also protects your dog if he bites someone. Dogs who have bitten humans are required to be confined for at least 10 days to see if rabies develops.
Vogt-Koyanagi-Harada syndrome is a condition seen in dogs characterized by uveitis (inflammation of the inside of the eye), poliosis (whitening of hair), and vitiligo (loss of pigment in the skin).[62]
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]
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.
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.
Nuclear sclerosis is a consistent finding in dogs greater than seven years old. Nuclear sclerosis appears as a bilateral bluish-grey haziness at the nucleus, or center of the lens,[62] and has little effect on vision.[66] This is may be confused with cataracts.[67]
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.
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]
I am sorry to hear about this, Slugger. We would advise that anytime there is a such a drastic change in your pet’s behavior that you call to consult a vet. This sounds like a very specific incident that it will be hard to diagnose and treat from reading articles. Sending lots of healing vibes your way.
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!
Elbow dysplasia is a condition found more commonly in large breeds. It incorporates several different hereditary conditions of the elbow, including osteochondritis of the medial condyle of the humerus, fragmentation of the medial coronoid process of the ulna, and ununited anconeal process of the ulna.[6]

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]
Valley Fever is the most serious and life-threatening of the group, mainly impacting hot, dry, dusty desert areas of California, Arizona, and Texas. The fungi are usually buried in the soil but can be displaced a number of ways—earthquakes, construction, rain—and released into the air where dogs can inhale it. If your dog develops respiratory symptoms, the disease can be deadly.
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.
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]

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.
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.
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]

Tick-borne diseases are common in dogs. Lyme disease, or borreliosis, is caused by Borrelia burgdorferi and spread by Ixodes pacificus on the West coast of the United States and by I. scapularis (deer tick) in the rest of the U.S. Signs and symptoms include fever, joint swelling and pain, lameness, and swelling of the lymph nodes. It has been diagnosed in dogs in all 48 states of the continental U.S.[7] Ehrlichia canis, which causes canine ehrlichiosis, and Rickettsia rickettsii, which causes Rocky Mountain spotted fever, are both spread by the American dog tick, Dermacentor variabilis, and the brown dog tick, Rhipicephalus sanguineous.[8]
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.

heart disease in dogs |

Vogt-Koyanagi-Harada syndrome is a condition seen in dogs characterized by uveitis (inflammation of the inside of the eye), poliosis (whitening of hair), and vitiligo (loss of pigment in the skin).[62]
Gastric dilatation volvulus, or gastric torsion and bloat, primarily affects breeds with deep, narrow chests, such as Great Danes, St. Bernards, German Shepherds, Standard Poodles and Irish Setters. The stomach twists on its supporting ligaments, sealing off the exits, and the contents begin to generate gas pressure which is very painful and rapidly causes shock and necrosis of large areas of stomach tissue. It can be fatal within a few hours. Dogs who have experienced bloat are very susceptible to recurrences. Treatment involves stabilization and abdominal surgery to tack the dog’s stomach down to prevent recurrence (gastropexy).[21]
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.
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]
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.
Kennel cough is a term loosely used to describe a complex of respiratory infections—both viral and bacterial—that causes inflammation of a dog’s voice box and windpipe. It’s a form of bronchitis and is similar to a chest cold in humans.

“Dogs will get a fever, they’ll feel kind of run down, they’ll get a runny nose, runny eyes, and a cough. That’s usually the main thing the main things will people will see,” he told CTV’s Your Morning Wednesday, adding that some dogs also develop mild diarrhea or vomiting.
Symptoms of chocolate poisoning include vomiting, diarrhea, pacing, panting, and shaking. More serious cases could cause an irregular heart beat, seizures, heart attack, or even death. If you think you dog has eaten any chocolate, do not wait to take him to the doctor.
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.
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]
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:
Parasites, particularly intestinal worms such as hookworms, tapeworms and roundworms, can be transmitted in a dog’s feces. Some tapeworms have fleas as intermediate hosts: the worm egg must be consumed by a flea to hatch, then the infected flea must be ingested (usually by the dog while grooming itself, but occasionally by a human through various means) for the adult worm to establish itself in the intestines. The worm’s eggs then pass through the intestines and adhere to the nether regions of the dog, and the cycle begins again.
There are several fungal diseases that are systemic in nature, meaning they are affecting multiple body systems. Blastomycosis, caused by Blastomyces dermatitidis, is a fungal disease that affects both dogs and humans, although it is only rarely zoonotic. It is found mainly in the United States in the Mississippi River and Great Lakes areas. It has also been reported in four Canadian provinces; Saskatchewan, Manitoba, Ontario and Quebec. Signs include weight loss, cough, fever, enlarged lymph nodes, draining skin lesions, eye inflammation with discharge, blindness, and lameness. Because dogs are ten times more likely to become infected from the environment than humans, they are considered to be sentinels for the disease. Treatment requires a minimum 60-90 day course of oral antifungal medication or in severe cases intravenous antifungal injections.[10]
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?
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]
Hydatidosis is caused by a cestode Echinococcus. This is usually noticed among dogs, wild dogs, foxes, etc. Due to its importance as a zoonosis, these worms are important to treat. Preventing hydatidosis is an easier task than treating the same. Anthelmintics such as praziquantel may help prevent this condition. Prohibition of the feeding of dogs with uncooked offals may be the best prophylactic measure against these tapeworms.

Patent ductus arteriosus* is one of the most common congenital heart defect in dogs around the world. It is inherited in toy and miniature Poodles, and seen commonly in German Shepherds, Pomeranians, Bichon Frises, and Malteses. Signs include a continuous heart murmur, bounding (strong) femoral pulse, tachypnea (increased breathing rate), dyspnea (labored breathing), and exercise intolerance.[49]
Some 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.
Welcome to the petMD Dog Symptom Checker, where you can easily search our 1,000+ dog health articles based on the symptoms your dog is experiencing. Simply select the area of the body that is being affected and then check off any appropriate symptom(s). Articles relevant to your query will appear below.
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.
Although germs from dogs rarely spread to people, they might cause a variety of illnesses, ranging from minor skin infections to serious disease. To protect yourself and your family from getting sick:
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.
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 (*).
If a lump is present, the first step is typically a needle biopsy, which removes a very small tissue sample for microscopic examination of cells. Alternately, surgery may be performed to remove all or part of the lump for diagnosis by a pathologist.
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]
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.
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.
2. Heartworm: Heartworm is a disease spread by mosquitoes and it has been diagnosed in all 50 states. While it is much more common in dogs, cats can also acquire the disease. If the infection is caught early enough in dogs, it can generally be treated, but there is no cure for feline heartworm disease. Therefore, the best way to keep your pets heart free of potentially deadly worms, is through a monthly preventative, prescribed by your veterinarian.

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.
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]

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.
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.
Sensitivity to anaesthesia can occur in any breed, but sighthounds have been the breeds most documented to have anesthetic concerns. Sighthounds are known to have prolonged recovery times from ultra short-acting thiobarbiturates such as thiopental.[164]
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]
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.

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.
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]
5. Distemper: Distemper is a tragic, often fatal disease of dogs and puppies. While the distemper virus is part of the typical puppy vaccine series, puppies too young for vaccination and dogs who were never vaccinated are most vulnerable. The virus typically comes along with neurological symptoms, nasal discharge, and high fevers. It also has a high mortality rate, and the rare dogs who survive infection often bear long-term effects, such as seizures and hardened paw pads.
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]
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]
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.
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.
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]

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.
Cerebellar abiotrophy is caused by the death of Purkinje cells in the cerebellum. It results in progressive ataxia beginning at a young age. It is most commonly seen in Kerry Blue Terriers and Gordon Setters.[56]

Prostate cancer* is rare in dogs and occurs in both intact and neutered animals. It is malignant. The most common type is adenocarcinoma. Signs include blood in the urine and straining to urinate or defecate. It most commonly spreads to bone and the lungs.[161]
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.
Blastomycosis is another very serious fungal disease that affects dogs near the Great Lakes region and other Eastern U.S. river basins. The fungus lives in soil sheltered from the sun, mainly along riverbanks, lakes, and swamps. Most dogs who get it live within 400 meters of a body of water. Large breed male dogs are most at risk and symptoms typically include difficulty breathing, skin lesions, and loss of appetite.
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]
What to look for: Arthritis usually, but not always, affects dogs as they grow older. It is the most common health problem in older pets. Your dog will eventually begin to move around less and take more time getting up from lying or seated positions.
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.
“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.
Osteochondritis dissecans (OCD) is separation of immature articular cartilage from underlying bone. It is caused by osteochondrosis, which is characterized by abnormal endochondral ossification of epiphyseal cartilage. It is most commonly seen in the stifle, elbow, shoulder, and hock.[37]
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.
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.
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  
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]

Deafness* in dogs can be either acquired or congenital. Predisposing factors for acquired deafness include chronic infection, use of certain drugs, and most commonly, age-related changes in the cochlea. Congenital deafness can be genetic, seen sometimes in dogs with merle or white coats, or caused by in utero damage from infections or toxins.[75]
Dental disease is very common. Calculus is the most obvious sign, but gingivitis progressing to periodontitis is what results in tooth loss. Treatment involves scaling and polishing of the teeth under general anesthesia and treatment of any periodontal disease. Prevention is very important and can be accomplished through the use of special diets or treats, brushing, and plaque prevention gels.[176]
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]
If your veterinarian has diagnosed your dog with ringworm, he or she will explain what you must do to prevent the fungus from spreading to your other pets—and to the human members of the household. But keep in mind that if you have other pets, it’s likely that most of them have been exposed as well. Your veterinarian may recommend that you do the following:
Samoyed hereditary glomerulopathy (SHG) is an hereditary noninflammatory disease, of the renal glomeruli occurring in the Samoyed breed of dog. The disease has been shown to be a model for hereditary nephritis (HN) in humans[153]
Collie eye anomaly (CEA) is a congenital, inherited, bilateral eye disease of dogs involving the retina, choroid, and sclera. It can be a mild disease or cause blindness. It is known to occur in Smooth and Rough Collies, Shetland Sheepdogs, Australian Shepherds, Border Collies, and Nova Scotia Duck Tolling Retrievers.[62]
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]
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.
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]

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]

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.
How to treat: Sadly, arthritis cannot be cured, but there are things you can do to make it easier on your pet as he ages. Diet and nutrition are the two biggest things you can do to slow down the aging (and arthritis) process. Regular walks and a balanced diet of proper (age appropriate) food will keep your dog’s nutrition levels where they should be. Look for food labeled “Senior” and pay attention not to over or under feed. If your dog’s arthritis is severe, your vet can prescribe medications to alleviate the symptoms.
It’s great when our dogs are at optimum health however when you know something isn’t quite right, we all like to be well prepared as possible with the right information on how to deal with any health issues that may arise. There are a number of factors that can cause dog health issues, many of these are dependent on the breed of your dog, genetics, its age, physical fitness, diet and the environment in which you live in.

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.
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.
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.
Ear infections are a common canine health problem, and they can be caused by allergies, yeast, ear mites, bacteria, hair growth deep in the ear canal, and more. Symptoms your dog may have with an ear infection include:
Lyme disease* is a disease caused by Borrelia burgdorferi, a spirochaete, and spread by ticks of the genus Ixodes. Symptoms in dogs include acute arthritis, anorexia and lethargy. There is no rash as is typically seen in humans.[11]
Sensitivity to anaesthesia can occur in any breed, but sighthounds have been the breeds most documented to have anesthetic concerns. Sighthounds are known to have prolonged recovery times from ultra short-acting thiobarbiturates such as thiopental.[164]
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.
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.
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]
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.
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]

Kanye West’s Adidas Yeezy shoe designs are typically met with Air Jordan-level fanfare when they’re released, but fans are accusing the rapper of phoning it in with his most recent design, which some say resembles Crocs.
Atopy* is an allergy to a substance with which the dog is not necessarily in direct contact. It is a type I hypersensitivity to a substance that is inhaled or absorbed through the skin. Up to 10 percent of dogs are affected.[77] It is common in dogs, especially seen in breeds such as Labrador Retrievers, Golden Retrievers, and Shih Tzus. The most common symptom is itching. Affected areas include the underside, the face, the feet, and the ears.[78]
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).

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.
For most dogs, insulin injections are necessary for adequate regulation of blood glucose. Once your pet’s individual insulin treatment is established, typically based on weight, you will be shown how to give him his insulin injections at home.
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]
As your veterinarian will explain, it’s important to always give your dog insulin at the same time every day and feed him regular meals in conjunction with his medication; this allows increased nutrients in the blood to coincide with peak insulin levels. This will lessen the chance that her sugar levels will swing either too high or too low. You can work with your vet to create a feeding schedule around your pet’s medication time. It is also important to avoid feeding your diabetic dog treats that are high in glucose. Regular blood glucose checks are a critical part of monitoring and treating any diabetic patient, and your veterinarian will help you set up a schedule for checking your dog’s blood sugar.
Cryptococcosis* is a fungal disease caused by Cryptococcus neoformans that affects both dogs and humans. It is a rare disease in dogs, with cats seven to ten times more likely to be infected. The disease in dogs can affect the lungs and skin, but more commonly the eye and central nervous system.[20]
Campylobacter spreads through contaminated food (meat and eggs), water, or contact with stool of infected animals. Dogs infected with Campylobacter might show no signs of illness at all or might have diarrhea and a slight fever.
Chocolate poisoning symptoms can last up to 72 hours. PetMD offers this chocolate toxicity meter to gauge your dog’s level of poisoning, but it’s still best to see a vet right away. For a true life story, read our post, My Dog Ate Chocolate. Here’s What Happened Next.
Pemphigus is an uncommon autoimmune skin disease. The most common form in dogs is pemphigus foliaceus, which manifests as erosions and crusting of the skin and mucocutaneous junctions. Pemphigus vulgaris is more rare and manifests as blister-like lesions in the mouth and at mucocutaneous junctions. Bullous pemphigoid is most commonly seen in Dobermanns and Collies and appears as a scald-like lesion of the groin.[81]
Mouse and rat poisons containing cholecalciferol cause hypercalcemia and hyperphosphatemia in dogs. Clinical signs include depression, loss of appetite, vomiting blood, weakness, and shock. Treatment is as above for recent exposure. When hypercalcemia occurs (which can take 1 to 2 weeks), treatment is with intravenous fluids (saline), diuretics, corticosteroids, and calcitonin. Long term prognosis is good once the dog is stabilized.
Cryptorchidism is when one the testicles is retained in the abdomen or inguinal canal past a normal stage of development. It is a common occurrence in dogs and is thought to be a sex-limited autosomal recessive trait.[6]
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.

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.
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]
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]
What to look for: No one wants to think about their dog getting cancer. It is one of the biggest killers in dogs and one of the most expensive diseases to treat. Look out for unusual odors, lumps, drastic weight loss, or long-lasting changes in behavior.
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]

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.
Cryptosporidium can cause profuse, watery diarrhea with cramping, abdominal pain, and nausea in both animals and people. Illness in people is usually self-limiting and lasts only 2-4 days, but can become severe in people with weakened immune systems.
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.
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.
Uveitis* is inflammation within the eye. Anterior uveitis (inflammation of the iris and ciliary body) is most common in dogs. The disease is usually immune-mediated in dogs, but may also be caused by trauma, cataracts, infectious canine hepatitis, leptospirosis, ehrlichiosis, or systemic fungal infections.[73]

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]
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]
There has been some speculation that walking dogs in particular areas of the countryside may be a contributing factor, but the Forestry Commission has yet to warn of any specific sites being dangerous, reassuring dog owners by saying “Many thousands of dogs are walked in the countryside every day and it is important to remember that only a very small number of dogs have been affected.”
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.

The first sign of Alabama Rot is skin sores that have not been caused by a physical injury. These sores can present as lesions, swelling, a patch of red skin, or may be open and ulcer-like. The sores are most commonly found below the knee or elbow or occasionally on the stomach or face. Usually, this will cause localised hair loss and the dog will begin licking the wound. These lesions will be followed – between two and seven days later – with outward symptoms of kidney failure: reduced appetite, fatigue, and vomiting. 

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.
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.

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]
Does your dog wolf his food down in a blink of an eye? Then he may be at risk of bloat, which is basically an enlarged stomach; this can become even more complicated if the stomach also turns. This prevents fluid and air from escaping the stomach, which prevents the dog from belching or vomiting.
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]
The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.
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]
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.
Samoyed hereditary glomerulopathy (SHG) is an hereditary noninflammatory disease, of the renal glomeruli occurring in the Samoyed breed of dog. The disease has been shown to be a model for hereditary nephritis (HN) in humans[153]
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]
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.
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.
Canine parvovirus is an acute illness, which means that symptoms develop suddenly, usually within 3–10 days of exposure. In most cases, dogs that are infected with the virus do not develop the disease (called asymptomatic infection). Canine parvovirus often is fatal in puppies. Sometimes, puppies collapse and die without showing prior signs of infection.

Tapeworms* are also common and in the dog are usually Dipylidium caninum, which is spread by ingesting fleas and lice. Also common is Taenia pisiformis, spread by ingesting rabbits and rodents. Rare tapeworm infections are caused by species of the genera Echinococcus, Mesocestoides, and Spirometra. There are usually no symptoms.[6]

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]
Although the name suggests otherwise, ringworm isn’t caused by a worm at all—but a fungus that can infect the skin, hair and nails. This highly contagious disease can lead to patchy areas of hair loss on a dog and can spread to other animals—and to humans, too.
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.
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.

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.
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 (*).
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]

what causes yeast infections in dogs |

Gastric dilatation volvulus, or gastric torsion and bloat, primarily affects breeds with deep, narrow chests, such as Great Danes, St. Bernards, German Shepherds, Standard Poodles and Irish Setters. The stomach twists on its supporting ligaments, sealing off the exits, and the contents begin to generate gas pressure which is very painful and rapidly causes shock and necrosis of large areas of stomach tissue. It can be fatal within a few hours. Dogs who have experienced bloat are very susceptible to recurrences. Treatment involves stabilization and abdominal surgery to tack the dog’s stomach down to prevent recurrence (gastropexy).[21]
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.
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]
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]
“The cause of Alabama Rot, clinically known as idiopathic cutaneous and renal glomerular vasculopathy (CRGV), is still unknown and there is no known way to prevent a dog from contracting the disease,” said David Walker, from Anderson Moores.
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]
Does your dog wolf his food down in a blink of an eye? Then he may be at risk of bloat, which is basically an enlarged stomach; this can become even more complicated if the stomach also turns. This prevents fluid and air from escaping the stomach, which prevents the dog from belching or vomiting.
Vestibular disease* is an uncommon condition in older dogs. Most cases are idiopathic, but it can also be caused by otitis interna, or inner ear infection, tumors, and encephalitis. Signs include nystagmus, head tilt, circling, vomiting, and falling to one side. Idiopathic vestibular disease will usually resolve in a few days to a few weeks.[173]
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]
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?
Ringworm is a condition caused by a fungus that can infect skin, hair, and nails of both people and animals. Ringworm is transmitted from animals to people through direct contact with an infected animal’s skin or hair. Puppies are most commonly affected and can have circular areas of hair loss anywhere on the body.
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]
Female cats and dogs are seven times more likely to develop mammary tumors if they are not spayed before their first heat cycle.[73] The high dietary estrogen content of the average commercial pet food may be contributing factors in the development of mammary cancer, especially when these exogenous sources are added to those normal estrogens produced by the body. Dog food containing soybeans or soybean fractions have been found to contain phytoestrogens in levels that could have biological effects when ingested longterm.[74]
Uveitis* is inflammation within the eye. Anterior uveitis (inflammation of the iris and ciliary body) is most common in dogs. The disease is usually immune-mediated in dogs, but may also be caused by trauma, cataracts, infectious canine hepatitis, leptospirosis, ehrlichiosis, or systemic fungal infections.[73]
However, there is one cause of chronic kidney disease that is preventable: dental disease. In the advanced stages of dental disease, bacteria from the dog’s gums can enter the bloodstream and damage vital organs, like the kidneys.
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]
Hops, a plant used in making beer, can cause malignant hyperthermia in dogs, usually with fatal results. Certain breeds, such as Greyhounds, seem particularly sensitive to hop toxicity, but hops should be kept away from all dogs. Even small amounts of hops can trigger a potentially deadly reaction, even if the hops are “spent” after use in brewing.[49]
How to treat: Prevention is your best option. It starts with getting your dog shots every year. You should also monitor your dog’s activity to make sure he isn’t interacting with rabies infected animals in the wild. If you suspect that your dog has rabies, call Animal Control immediately and avoid your dog as much as possible.
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.
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]

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]
Epilepsy in dogs can be a primary, idiopathic, inherited disorder or secondary to previous head trauma or CNS infections. Idiopathic epilepsy is commonly found in breeds such as German Shepherd Dogs, Beagles, and Dachshunds. The most common sign recurring generalized seizures beginning at a young adult age.[56]
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]
Veterinary parasitology studies both external and internal parasites in animals. External parasites, such as fleas, mites, ticks and mosquitoes can cause skin irritation and are often carriers of other diseases or of internal parasites.
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.
People start showing signs 2-14 days after exposure; these may include fever, rash, headache, nausea, vomiting, abdominal pain, and muscle pain. RMSF can develop into a serious illness if not promptly treated.
Blastomycosis is another very serious fungal disease that affects dogs near the Great Lakes region and other Eastern U.S. river basins. The fungus lives in soil sheltered from the sun, mainly along riverbanks, lakes, and swamps. Most dogs who get it live within 400 meters of a body of water. Large breed male dogs are most at risk and symptoms typically include difficulty breathing, skin lesions, and loss of appetite.
Nutritious mass-market food abounds, says Linda Case, author of Dog Food Logic, but some of the best products come from smaller companies that make food in their own US facilities. Sure, you can feed your dog on 15 cents a day, but making the investment in higher-priced food, say at a few dollars a day, can mean the difference between giving your dog chicken and serving it ground chicken heads (yes, gross!). Tip: Grain should not be one of the first two ingredients on the label, and the protein source should be named (“trout” not “fish,” for example). Bonus: Worried about pet-food recalls? Follow the American Veterinary Medical Association on Twitter @AVMARecallWatch or its Facebook page to stay informed.
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.
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]
Yes, puppies are a bundle of energy, but even they need disciplined exercise like leash walks. However, don’t start running and hiking with your pooch until your larger-breed dog is at least 1.5 years old. This will help avoid injuries while the growth plates in the legs and other long bones are still knitting closed. Tip: Be sure to build up your dog’s endurance, just as you did your own, if you’re hoping to take it with you on those marathon-training runs.

Canine parvovirus is an acute illness, which means that symptoms develop suddenly, usually within 3–10 days of exposure. In most cases, dogs that are infected with the virus do not develop the disease (called asymptomatic infection). Canine parvovirus often is fatal in puppies. Sometimes, puppies collapse and die without showing prior signs of infection.
Tick-borne diseases are common in dogs. Lyme disease, or borreliosis, is caused by Borrelia burgdorferi and spread by Ixodes pacificus on the West coast of the United States and by I. scapularis (deer tick) in the rest of the U.S. Signs and symptoms include fever, joint swelling and pain, lameness, and swelling of the lymph nodes. It has been diagnosed in dogs in all 48 states of the continental U.S.[7] Ehrlichia canis, which causes canine ehrlichiosis, and Rickettsia rickettsii, which causes Rocky Mountain spotted fever, are both spread by the American dog tick, Dermacentor variabilis, and the brown dog tick, Rhipicephalus sanguineous.[8]
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]

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.
Campylobacter spreads through contaminated food (meat and eggs), water, or contact with stool of infected animals. Dogs infected with Campylobacter might show no signs of illness at all or might have diarrhea and a slight fever.
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]
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.
For most dogs, insulin injections are necessary for adequate regulation of blood glucose. Once your pet’s individual insulin treatment is established, typically based on weight, you will be shown how to give him his insulin injections at home.
This tick-borne illness is another highly preventable disease. It is caused by a bacteria transmitted by slow-feeding deer ticks that have been attached to the dog for at least 18 hours. It’s the most common of the tick-related illnesses.
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]
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]
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]
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]
Rabies is a viral disease that may affect the brain and spinal cord of all mammals, including cats, dogs and humans. This preventable disease has been reported in every state except Hawaii. There’s good reason that the very word “rabies” evokes fear in people—once symptoms appear, rabies is close to 100% fatal.
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 (*).

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

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  
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]
Dog treats are often given to pets as a reward for something they did or just to let them chew on a bone, which works their jaw muscles and helps keep their teeth clean.[63] Although dog treats carry high benefits for dogs’ teeth, they can also be a source of problems when given excessively. The human food treats are usually the ones that cause the most trouble for dogs.

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]
Ticks* are an external parasite of the dog and can spread diseases such as Lyme disease, Rocky Mountain spotted fever, babesiosis, and ehrlichiosis. They can also cause a neurological disorder known as tick paralysis.[32]

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.
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.
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]
Dog treats given excessively can be a cause of obesity. The type of food fed has a direct bearing on the tendency of a dog to become overweight. Table scraps, treats, even premium high-energy dog foods can contribute to obesity.[64] Therefore, it is highly important to closely monitor the quantity of treats that a dog gets especially when the dog’s activity is diminished. Dog treats are more likely to be linked to obesity in old dogs, since in their old age they are less likely to be active and exercising. On the other hand, active dogs require and use more calories, so dog treats are not a cause of concern in younger and highly active dogs.
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]
The best way to diagnose a worm problem is with a visit to the vet. Treatment depends on which type of worm your dog has, but generally includes an oral medication and may require follow-up. Don’t try treating worms yourself: A medication that kills roundworms, for example, doesn’t kill tapeworms.
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. Humans and dogs become infected through contact with water, food, or soil containing urine from infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. In dogs, transmission most commonly occurs by drinking puddle, pond, or ditch water contaminated by urine from infected wildlife such as squirrels or raccoons. The liver and kidney are most commonly damaged by leptospirosis. Vasculitis can occur, causing edema and potentially disseminated intravascular coagulation (DIC). Myocarditis, pericarditis, meningitis, and uveitis are also possible sequelae.[5]

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.
“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.
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]
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.

They’re commonly known as hot spots, but the medical term for those bare, inflamed, red areas you often see on dogs is acute moist dermatitis — a bacterial skin infection. Anything that irritates your dog’s skin enough to make him scratch or chew can lead to the pain and itch of hot spots, which, if left untreated, can quickly grow larger.
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. 
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.
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]
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.
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]

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.
For most dogs, insulin injections are necessary for adequate regulation of blood glucose. Once your pet’s individual insulin treatment is established, typically based on weight, you will be shown how to give him his insulin injections at home.
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?
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.
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.

Congenital diaphragmatic hernia* is uncommon, and is usually caused by trauma. Congenital diaphragmatic hernias are usually communications between the peritoneum and pericardium and are usually incidental findings.[178]
Because diarrhea can easily lead to dehydration, be sure your dog has plenty of clean water available, then take your pooch to the vet if the diarrhea persists for more than a day, or immediately if there’s also fever, lethargy, vomiting, dark or bloody stools, or loss of appetite.

Rabies (hydrophobia) is a fatal viral disease that can affect any mammal, although the close relationship of dogs with humans makes canine rabies a zoonotic concern. Vaccination of dogs for rabies is commonly required by law. Please see the article dog health for information on this disease in dogs.[1]
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.
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]

Pythiosis is a disease cause by a water mould of the genus Pythium, P. insidiosum. It occurs primarily in dogs and horses, but can also affect humans. In dogs it affects the gastrointestinal system and lymph nodes, and rarely the skin.[24]
Pyometra is an infection of the uterus. It is a common and potentially fatal condition in dogs. The main risk period for a female is for eight weeks after her peak standing heat (or estrus cycle) has ended.[6]
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]
1. Obesity: Obesity has become as serious of a problem in our pets as it is in the human population. Sadly, overweight pets are more prone to heart disease, diabetes, arthritis, and premature death. But while underlying disease or slow metabolism might be a factor, all too often, pet obesity is caused by doting pet parents who overfeed and underexercise their cats and dogs. There is no quick fix for obesity, but, just like with a human diet, check with your veterinarian for feeding and exercise guidelines. It might be as easy as swapping the dog treats with green beans or giving your cat a five-minute run with the laser pointer before bed. It might sound crazy, but when it comes to obesity, we can love our pets to death. You can help your dogs and cats live long lives by giving them the tools to stay light on their paws.
An infectious disease is caused by the presence of organisms such as viruses, bacteria, fungi, or parasites (either animalian or protozoan). Most of these diseases are spread directly from dog to dog, while others require a vector such as a tick or mosquito.[1] Certain infectious diseases are a concern from a public health standpoint because they are zoonoses (transmittable to humans).
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]
Infected people will typically have a red “bull’s eye” rash at the site of the tick bite that appears about 7 days after being bitten. Flu-like symptoms quickly follow the rash. If not treated, this disease can spread to other parts of the body and cause symptoms such as arthritis and loss of facial muscle tone (Bell’s palsy). Lyme disease can be fatal.
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.
Finding out that a loved one has cancer can be very scary and confusing. When that loved one is your dog, it’s important to keep in mind that different veterinarians might have different views on the best way to treat the disease. It’s always a good idea to seek out a second opinion, perhaps from a veterinary oncologist, and carefully review your options.

Echinococcosis is a parasitic disease caused by eating or drinking food and water contaminated with a specific type of tapeworm eggs or through contact with an infected animal. Dogs become infected by eating tissue of an infected animal. Dogs rarely show any signs of disease, but if they are infected with a large number of worms, dogs can have diarrhea and enteritis.
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]
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]
Dermal fragility syndrome, also known as Ehlers–Danlos-like syndrome, is a rare condition in dogs characterized by increased skin elasticity and poor wound healing. There appears to be a genetic basis for the disease.[83]
So keep those chompers clean! Brush regularly throughout your dog’s lifetime—meaning at least once a week—offer bully sticks or other hard chew toys to remove plaque, or get a professional teeth cleaning done at your vet’s office, which requires anesthesia but is quite effective.
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.
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]
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.
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.

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.
How to treat: Sadly, arthritis cannot be cured, but there are things you can do to make it easier on your pet as he ages. Diet and nutrition are the two biggest things you can do to slow down the aging (and arthritis) process. Regular walks and a balanced diet of proper (age appropriate) food will keep your dog’s nutrition levels where they should be. Look for food labeled “Senior” and pay attention not to over or under feed. If your dog’s arthritis is severe, your vet can prescribe medications to alleviate the symptoms.

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

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.
The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.
Laryngeal paralysis is unilateral or bilateral paralysis of the larynx. In dogs it can be congenital, seen in the Bouvier des Flandres, Bull Terrier, Dalmatian, Rottweiler and Huskies, or an acquired, idiopathic disease, seen in older Labrador Retrievers, Golden Retrievers, St. Bernards, and Irish Setters. Signs include change in voice and difficulty breathing.[61]
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.
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]
We created a list for you and and any other dog owners too, so feel free to share! Print it out and/or save somewhere you can easily reference that way you have these conditions top of mind and know what symptoms to look for in case your dog is ill.
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.
Yes, puppies are a bundle of energy, but even they need disciplined exercise like leash walks. However, don’t start running and hiking with your pooch until your larger-breed dog is at least 1.5 years old. This will help avoid injuries while the growth plates in the legs and other long bones are still knitting closed. Tip: Be sure to build up your dog’s endurance, just as you did your own, if you’re hoping to take it with you on those marathon-training runs.

A dog who is up to date with his vaccinations and who has been bitten by a possibly rabid animal should also be given a rabies booster vaccine immediately and kept under observation (length will vary depending on your state laws).
