von Willebrand disease* is a common inherited disease in dogs caused by a deficiency of a protein called von Willebrand factor, which is involved in blood clotting. The disease varies from mild to severe, depending on the amount of von Willebrand factor present in the dog. Signs include spontaneous bleeding and excessive bleeding following surgery, injury, or during an estrous cycle.
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.
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.
Weese advises that, if you’re out and see a dog that’s coughing and looks sick, keep your dog away from that animal. If your dog does become sick with a cough or runny nose, keep it away from other pets for at least 2 weeks.
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.
Systemic lupus erythematosus (SLE)* is an immune system disease characterized by the presence of antibodies to nucleic acid and/or antibodies to red blood cells, platelets, lymphocytes, clotting factors, and thyroglobulin. The disease can result in deposition of immune complexes or autoimmune disease. Immune complex deposition can cause vasculitis, meningitis, neuritis, and joint and skin disease. The most commons signs are hemolytic anemia or thrombocytopenia.
Heart valve dysplasia (including mitral and tricuspid valve dysplasia) is a congenital heart abnormality in dogs. Dysplasia of the mitral and tricuspid valves – also known as the atrioventricular (AV) valves – can appear as thickened, shortened, or notched valves. Chordae tendineae are also usually abnormal.

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.
Toxocara roundworms cause a parasitic disease known as toxocariasis. Dogs and people can become infected by accidentally swallowing roundworm eggs from the environment. In addition, larval worms can cross through the placenta, milk, or colostrum of a mother dog, passing the infection to her puppies. Infected puppies usually do not develop and grow well and might have a pot-bellied appearance.
Cataracts* are an opacity in the lens of the eye. Most cataracts in dogs are caused by a genetic predisposition, but diabetes mellitus is also a common cause. The only effective treatment is surgical removal.
Nasal cancer makes up one to two percent of all types of tumors in dogs. Adenocarcinoma is the most common type, followed by sarcomas such as fiborsarcoma and chondrosarcoma. Signs include sneezing and bloody nasal discharge.
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. Prostatis can be associated with BPH. Bacteria causing prostatitis include E. coli, Staphylococcus spp., Streptococcus spp., and Mycoplasma spp.
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:

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.
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). 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.
Cor triatriatum*, specifically cor triatriatum dexter, occurs in dogs and is characterized by a fibrous division of the right atrium into two chambers, usually with a hole in between them. It results in right heart failure (ascites). It can be treated by balloon valvuloplasty or surgical resection.

“The first sign that is normally seen is a skin sore that isn’t caused by a known injury. Most commonly these sores are found below the elbow or knee and appear as a distinct swelling, a patch of red skin or are open and ulcer-like.
“He is soooo cute,” you thought when you first laid eyes on your dog. And—yay!—he seemed to like you too. So you brought him home—only to realize that maybe you weren’t totally prepared for the work this relationship involved. Well, your mom was right (again): Owning a dog IS a big responsibility, from training to feeding to keeping it stress-free. “We don’t have that many years with our dogs,” says Whole Dog Journal editor Nancy Kerns. Here’s how to make sure each day is filled with health—and happiness for you both.
There are topical medicines to repel and kill ticks you put directly on your dog’s fur, like Frontline and K9 Advantix. There are also pills, like NexGard, and even collars your dog can wear, like Preventic. Just keep in mind the effectiveness of topical medicines decreases through the month, especially if your dog goes swimming or has a bath. Year-round prevention is best.
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.

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.
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.
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.

There are some bacteria that are contagious from dog to dog. The most notable of these are Bordetella bronchiseptica, one of the causes of kennel cough, Leptospira sp, which cause leptospirosis, and Brucella canis, cause of brucellosis in dogs. There are also common tick-borne bacterial diseases, including Lyme disease, ehrlichiosis, and Rocky Mountain spotted fever.
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.
Being familiar with these common dog health issues should help you know which ones you can treat yourself, and when it’s time to see a vet. If you find yourself visiting the vet often perhaps pet insurance is something you should consider. It can greatly reduce your out-of-pocket cost when visiting your veterinarian. Check out our Pet Insurance Comparison to see which pet insurance providers might be a good fit for your family.
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.
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.
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

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

Hemorrhagic gastroenteritis is a disease of dogs characterized by sudden vomiting and bloody diarrhea. The symptoms are usually severe and can be fatal if not treated. It is most common in young adult dogs of any breed, but especially small dogs such as the Toy Poodle and Miniature Schnauzer.
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. 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.
Renal failure (kidney failure) * is common in dogs and may be found in acute or chronic forms. It is defined by a loss of function of about 75 percent of the filtration system of the kidney and characterized by azotemia and low specific gravity of the urine. Acute renal failure can be caused by loss of blood supply, hypercalcemia, or toxins such as ethylene glycol (antifreeze) or aminoglycoside antibiotics (see: ethylene glycol poisoning). Chronic renal failure can be congenital and/or inherited or caused by cancer, infection, hypertension, glomerulonephritis, amyloidosis, progressive interstitial fibrosis, or any of the causes of acute renal failure.
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.
Retinal dysplasia is an eye disease affecting the retina. It is usually a nonprogressive disease and can be caused by viral infections, drugs, vitamin A deficiency, or genetics. Retinal dysplasia is characterized by folds or rosettes (round clumps) of the retinal tissue.
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.
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.
The frequency of bilateral glaucoma with a genetic base in purebred dogs is higher than in any species except humans. Cataracts in dogs either have a genetic base or can also be caused by diabetes. Nuclear sclerosis resembles a cataract but is actually a normal age-related change.
About 4.5 million Americans receive dog bites each year, many of which require immediate medical attention. Young children 5 to 9 years old are most likely to bitten by dogs, with boys being bitten more often than girls.
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 risk for contracting rabies runs highest if your dog is exposed to wild animals. Outbreaks can occur in populations of wild animals (most often raccoons, bats, skunks and foxes in this country) or in areas where there are significant numbers of unvaccinated, free-roaming dogs and cats.
Umbilical hernia* is a failure of the umbilical ring of the abdominal wall to close. They are very common and can be caused by genetics or by traction on the umbilical cord or by the cord being cut too close to the body. They are corrected by surgery.
Granulomatous meningoencephalitis (GME) (including Pug Dog encephalitis and other noninfectious causes of meningoencephalitis) is an inflammatory disease of the central nervous system of dogs. It is a form of meningoencephalitis. The disease is more common in female toy dogs of young and middle age.
