“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.”
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.

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.

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.

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. Signs include increased appetite, increased drinking and urination, a pot-bellied appearance, muscle weakness, and lethargy. Cushing’s can be caused by overuse of steroid medications; in some cases, stopping the medication is enough to solve the problem. Diagnosis can be difficult as there are no tests with both high sensitivity and specificity. Treatments inclulde mitotane, trilostane, ketoconazole, or selegiline. Surgery is used in some cases of adrenal tumors.
Subaortic stenosis, or SAS, is a genetic ailment that causes a narrowing of the passage of blood between the heart and the aorta. This leads to heart problems and sometimes sudden death. It affects larger breeds such as the Newfoundland Dog and the Golden Retriever. In some dogs, such as collies, the blue merle or harlequin coloring is actually the heterozygote of a partially recessive gene preventing proper development of the nervous system; therefore, if two such dogs are mated, on the average one quarter of the puppies will have severe genetic defects in their nervous systems and sensory organs ranging from deafness to fatal flaws.
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.
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.
People become infected with dog hookworms while walking barefoot, kneeling, or sitting on ground contaminated with stool of infected animals. Hookworm larvae enter the top layers of skin and cause an itchy reaction called cutaneous larva migrans. A red squiggly line might appear where the larvae have migrated under the skin. Symptoms usually resolve without medical treatment in 4-6 weeks.
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.
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.
Cocoa within chocolate contains theobromine, a chemical stimulant that, together with caffeine and theophylline, belongs to the group of methylxanthine alkaloids. Dogs are unable to metabolize theobromine effectively. If they eat chocolate, the theobromine can remain in their bloodstreams for days, and dogs may experience fast heart rate, severe diarrhea, epileptic seizures, heart attacks, internal bleeding, and eventually death. “One ounce of milk chocolate per pound of body weight is a potentially lethal dose in dogs.” In case of accidental intake of chocolate by especially a smaller dog, contact a veterinarian or animal poison control immediately; it is commonly recommended to induce vomiting within two hours of ingestion. If chocolate ingestion is suspected (mostly dark or baking chocolate), hydrogen peroxide can be used to safely induce vomiting, then making a trip to the veterinarian is suggested. Large breeds are less susceptible to chocolate poisoning, but can still die after eating four ounces of chocolate.
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.
People who are infected with brucellosis will usually become sick within 6-8 weeks of exposure. Sick people will have flu-like symptoms that last 2-4 weeks. Sometimes brucellosis can become a chronic illness that can be difficult to treat.
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.
Avoid bites and scratches from dogs. Dog bites might become seriously infected or might be a source of rabies. Be cautious with unfamiliar animals. Approach dogs with care, even if they seem friendly.
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.
Female cats and dogs are seven times more likely to develop mammary tumors if they are not spayed before their first heat cycle. 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.

As the name suggests, an infected mosquito injects a larva into the dog’s skin, where it migrates to the circulatory system and takes up residence in the pulmonary arteries and heart, growing and reproducing to an alarming degree. The effects on the dog are quite predictable, cardiac failure over a year or two, leading to death. Treatment of an infected dog is difficult, involving an attempt to poison the healthy worm with arsenic compounds without killing the weakened dog, and frequently does not succeed. Prevention is much the better course, via heartworm prophylactics which contain a compound which kills the larvae immediately upon infection without harming the dog. Often they are available combined with other parasite preventives.
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.
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.

Vaccinations are an important preventative animal health measure. The specific vaccinations recommended for dogs varies depending on geographic location, environment, travel history, and the activities the animal frequently engages in. In the United States, regardless of any of these factors, it is usually highly recommended that dogs be vaccinated against rabies, canine parvovirus, canine distemper, and infectious canine hepatitis (using canine adenovirus type 2 to avoid reaction). The decision on whether to vaccinate against other diseases, including leptospirosis, Lyme disease, Bordetella bronchiseptica, parainfluenza virus, and canine coronavirus, should be made between an owner and a veterinarian, taking into account factors specific to the dog.
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.
