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 (*).
“Chase has no known medical history, so everything was on the table, and that was a problem,” owner Scott Picken said. “It wasn’t until the fourth vet visit that a blasto test was done and by the time it came back positive, he was pretty sick.”
How to treat: A steady diet and regular exercise are the two things needed when your dog is overweight. It’s important to recognize the severity of your dog’s obesity and be sure to administer the right changes in nutrition and exercise. Too much exercise, or too significant a reduction in food, can cause other issues, so you should consult your vet before making any drastic changes to the diet.

Demodicosis, also known as demodectic mange, is caused by Demodex canis mites which live in small numbers in sebaceous glands and hair follicles. These mites can cause inflammation and hair loss, and may also lead to secondary bacterial infections such as fever, lethargy, and enlarged lymph nodes.
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.
Note: Do not attempt to handle or capture a wild animal who is acting strangely (i.e., a nocturnal animal who is out during the day, an animal who acts unusually tame). Report the animal to local animal control officers as soon as possible.
Ever think, “I should Spin more,” and then remember how much you hate Spinning? Same for dogs. Not every dog is a runner or a swimmer or will want to play fetch. In fact, says Case, “If you haven’t started your dog swimming before the age of 1 or 2, it’s not going to like it”—even if it has webbed feet. “There are many more owners who want their dogs to swim than there are dogs that want to get in the water.” Tip: There’s no real data on the optimum cardio workout for dogs, says Kerns, “but the more you can get your dog outside—with the sun overhead and grass under its paws—the better.”
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.
Lick granuloma also known as acral lick dermatitis, is a skin disorder in dogs resulting from an urge to lick the lower portion of the leg. The lesion from the incessant licking is a thickened, firm, oval plaque.
Alcohols Commonly encountered alcohols in veterinary medicine are isopropanol and methanol found in household products and ethanol from alcoholic beverages. They all pose toxicity to dogs. Isopropanol which is found in rubbing alcohol has twice the toxicity of ethanol; however methanol which can be found in windshield washer fluid does not have the same retinal and neuronal toxicity on dogs as it does to humans and primates due to the differences in the way its metabolite formic acid is processed.
Pica is an appetite for, or the behavior of eating, non-nutritive substances (e.g., sand, coal, soil, chalk, paper etc.). Pica can be dangerous to dogs, with a risk from eating dirt near roads that existed prior to the phaseout of tetraethyllead in gasoline or prior to the cessation of the use of contaminated oil (either used, or containing toxic PCBs) to settle dust. In addition to poisoning, there is a risk of gastro-intestinal obstruction or tearing in the stomach or blockage of the esophagus.
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.
Thrombocytopenia* is a common condition in dogs characterized by low platelet counts. Platelets are used in clotting the blood, so dogs with this condition may have spontaneous bleeding or prolonged bleeding following surgery, injury, or during an estrous cycle. Causes include some rickettsial infections such as ehrlichiosis, cancers such as hemangiosarcoma, or immune-mediated disease.

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.

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.
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.
Certain types of dog or puppy adoptions, like international pet adoption, might not be suitable for your family because of the risk for disease. This is particularly true if young children, pregnant women, or persons with weak immune systems are living in the household. Persons with weak immune systems may include the elderly or people with an illness such as diabetes or HIV/AIDS, or those undergoing chemotherapy.
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.
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.

Some dog owners opt for no treatment of the cancer, in which case palliative end of life care, including pain relief, should be considered. Regardless of how you proceed after a diagnosis of cancer in your pet, it is very important to consider his quality of life when making future decisions.

Spondylosis*, known as spondylosis deformans in dogs, is growth of osteophytes on the ventral and lateral surfaces of the vertebral bodies. It is usually an incidental finding on radiographs and rarely causes symptoms.
Osteoarthritis*, also known as degenerative arthritis, is a common condition in dogs characterized by progressive deterioration of articular cartilage in the joints of the limbs. It can cause a great deal of pain and lameness. Treatment options include medications such as NSAIDs, corticosteroids, and joint fluid modifiers such as glycosaminoglycans. Other treatments include surgery, massage, warm compresses, chiropractic, and acupuncture.
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).
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.
The best outcomes seem to be achieved by catching it early and the animal receiving high-quality veterinary care. Whilst some infected dogs do survive the treatments of skin sores and kidney failure, unfortunately, many do not – it is estimated that treatment is only successful in around 20-30% of cases.
