Contact your veterinarian immediately if your dog shows any of the clinical signs mentioned on the list above. Should your dog receive a diagnosis of cancer, you may wish to consult a veterinary oncologist, often employed by specialty veterinary practices and teaching hospitals.
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.
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.
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.
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.
Grapes and raisins can cause acute kidney failure in dogs  (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. The most common pathological finding is proximal renal tubular necrosis.
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.
Tetralogy of Fallot* is a congenital heart defect in dogs that includes four separate defects: pulmonic stenosis, a ventricular septal defect, right ventricular hypertrophy, and an overriding aorta. Keeshonds and Bulldogs are predisposed. Signs include cyanosis and exercise intolerance. Polycythemia is often present and, if severe, needs to be controlled with phlebotomy or drugs to suppress red blood cell production.
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.
Rabies, a fatal neurologic disease in animals and people, is caused by a virus. Animals and people are most commonly infected through bites from rabid animals. Infected dogs might have a variety of signs, but most often have a sudden behavioral change and progressive paralysis. Rabies is prevented by vaccination.
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.
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.
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.
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. 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. 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.
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.
So what is a severe case? How about up to 250 worms living in your dog for several years! Better just get the more cost-effective heartworm medication; there are pills, topicals, and injections, some of which also prevent other types of worms.
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.

On the other hand, acute kidney disease is largely preventable. Acute kidney disease is caused by a number of issues: poisoning, infection, or complication from medicines, to name a few. Symptoms are sudden and severe and can include fever, vomiting, change in water intake, change in appetite, and change in amount of urination.
My human went to the pumpkin patch and brought back several lovely pumpkins for the porch. I was bummed because I couldn’t get her to throw them like balls for me. They looked like balls. She saw how disappointed I was and got me this pumpkin dog toy. She throws it and I chase it, and we both smile. And I leave the real pumpkins alone.
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.
Rocky Mountain spotted fever* is a rickettsial disease that occurs in dogs and humans. It is caused by Rickettsia rickettsii and spread by ticks of the genus Dermacentor. Signs are similar to human disease, including anorexia, fever, and thrombocytopenia.
Distichia (including ectopic cilia) is an eyelash that arises from an abnormal spot on the eyelid. Distichiae usually cause no symptoms because the lashes are soft, but they can irritate the eye and cause tearing, squinting, inflammation, and corneal ulcers.
Because parvovirus can live in an environment for months, take extra care if there has been an infected dog in your house or yard. Parvo is resistant to many typical disinfectants and can be difficult to eradicate.
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.
