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.
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.

Some cancers can be cured, while others cannot. Please note that if your dog’s cancer is not curable, there are still many things you can do to make your pet feel better. Don’t hesitate to talk to your vet about your options. And remember good nutrition and loving care can greatly enhance your dog’s quality of life.
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. 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.
Dog hookworms are tiny worms that can spread through contact with contaminated soil or sand. Dogs can also become infected with hookworms through accidentally ingesting the parasite from the environment or through their mother’s milk or colostrum. Young puppies are most often affected and might have dark, bloody stool and anemia. Severe infections in some puppies can lead to death.
If your dog becomes sick or dies soon after purchase or adoption, take your dog to the veterinarian promptly, and inform the pet store, breeder, or rescue organization about the pet’s illness or death. Make sure to tell your veterinarian if the pet was adopted internationally. Thoroughly clean the area occupied by your pet, and consider waiting at least a few weeks before purchasing or adopting another pet.
Cardiomyopathy, or disease of the heart muscle, is also seen in dogs and is associated with large breeds (the exception being Cocker Spaniels, a medium-sized breed). Dilated cardiomyopathy is seen in Great Danes, Irish Wolfhounds, St. Bernards, Dobermanns, Boxers, and other large breeds. Dobermanns, in addition to heart muscle failure, are prone to ventricular arrhythmias. Boxer dogs are predisposed to a unique cardiomyopathy with clinical and histological changes analogous to human arrhythmogenic right ventricular cardiomyopathy (ARVC). The disease has been termed “Boxer cardiomyopathy” or “Boxer ARVC”, and is characterized by development of ventricular tachyarrhythmias. Affected dogs are at risk of syncope and sudden cardiac death. Myocardial failure and congestive heart failure are rare manifestations of this disease.
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.
Orthopedic diseases in dogs can be developmental, hereditary, traumatic, or degenerative. Because of the active nature of dogs, injuries happen frequently. One of the most common of these is an anterior cruciate ligament injury, a condition which often requires surgery. Bone fractures are a frequent occurrence in outdoor dogs due to trauma from being hit by cars. Degenerative joint disease is common in older dogs and is one of the most likely reasons for prescription of non-steroidal anti-inflammatory drugs.
Infectious diseases that affect dogs are important not only from a veterinary standpoint, but also because of the risk to public health; an example of this is rabies. Genetic disorders also affect dogs, often due to selective breeding to produce individual dog breeds. Due to the popularity of both commercial and homemade dog foods, nutrition is also a heavily studied subject.
Antifreeze* is very dangerous to dogs and causes central nervous system depression and acute renal failure. Treatment needs to be within eight hours of ingestion to be successful. See Ethylene glycol poisoning.
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.
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.
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.
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.
Staphylococcus aureus is a common type of bacteria that is normally found on the skin of people and animals. Methicillin-resistant Staphylococcus aureus (MRSA) is the same bacterium that has become resistant to some antibiotics. Dogs and other animals often can carry MRSA without being sick, but MRSA can cause a variety of infections, including of the skin, respiratory tract, and urinary tract.
Rocky Mountain spotted fever (RMSF) is a bacterial disease transmitted to dogs and people by ticks. Dogs show a variety of symptoms similar to those in people, including fever, lameness, coughing, vomiting and diarrhea, and swelling of the face or extremities.
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.
Malignant histiocytosis (histiocytic sarcoma) is an aggressive cancer found primarily in certain breeds including the Bernese Mountain Dog, rottweiler, golden retriever and flat coated retriever. It is characterized by infiltration of the joints, lungs, spleen, lymph nodes, and other organs by malignant histiocytes.
Pulmonary hypertension* is high pressure in the pulmonary artery. In dogs it can be caused by heartworm disease, pulmonary thromboembolism, or chronic hypoxemia (low oxygen). It can result in right-sided heart disease (cor pulmonale). Signs include difficulty breathing, cyanosis, and exercise intolerance.
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.

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.
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.
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.

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.
“Some will get secondary infections with bacteria. Some dogs can die but it’s pretty uncommon. That’s more likely in dogs that already have other diseases: respiratory disease, heart disease or other things that make them more likely to get a serious illness,” he said.
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.
“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.
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.
Bilious vomiting syndrome is vomiting in response to bile-induced inflammation of the stomach. Bile salts interfere with the gastric mucosal barrier, allowing acid to irritate the stomach lining and cause gastritis.
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.
Coccidioidomycosis* is a fungal disease caused by Coccidioides immitis or Coccidioides posadasii that affects a variety of species, including dogs. In dogs signs of primary pulmonary disease include a cough, fever, weight loss, anorexia, and lethargy. Disseminated disease occurs when the fungus has spread outside of the lungs and may include clinical signs such as lameness, pain, seizures, anterior uveitis, and localized swelling. Diagnosis of Valley Fever may include multiple tests, including serology and radiology. According to a study performed in the Tucson and Phoenix area, 28% of dogs will test positive for exposure to the fungus by two years of age, but only 6% of the dogs will be ill with clinical disease. There is an increased risk of infection associated with amount of time spent outdoors, a larger roaming space accessed by the dog, and increasing age.
Diabetes insipidus* in dogs can be central, caused by a lack of antidiuretic hormone (ADH), or nephrogenic, caused by a lack of response of the kidneys to ADH. Neither form is common. Central diabetes insipidus (CDI) is usually idiopathic, but can also be caused by head trauma or tumors of the brain. Nephrogenic diabetes insipidus (NDI) can be primary (hereditary) or secondary (caused by a variety of metabolic and renal diseases, including Cushing’s syndrome and pyometra). Because the disease is characterized by an inability to concentrate urine, the most common sign is increased drinking and urinating. Treatment of CDI is to use desmopressin, a synthetic analog of ADH. Treatment of NDI is to treat the underlying cause, if any.

Insecticides* used in dogs for fleas and ticks commonly contain either organophosphates or carbamates. they can be absorbed through the skin, conjunctiva, gastrointestinal tract, and lungs. Organophosphates inhibit acetylcholinesterase irreversibly and carbamates inhibit cholinesterase reversibly. Toxicity occurs through overdosage with an appropriate product or use of an agricultural product. Signs for both include hypersalivation, vomiting, lethargy, tremors, difficulty walking, weakness, and death.
Glomerulonephritis* is the presence of immune complexes in the glomerulus, resulting in leakage of protein into the urine. It can be caused by cancer, heartworm disease, pyometra, rickettsial infection, or systemic lupus erythematosus. It can result in chronic kidney failure, hypoalbuminemia, which can cause ascites and peripheral edema, and nephrotic syndrome, which can cause hypertension or hypercoagulability.
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.
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).
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.
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.
