Lead poisoning* is uncommon in dogs. Exposure to lead is from eating paint chips from lead-based paint (found in houses painted prior to 1950), and eating lead objects such as shot, fishing sinkers, or counterweights. Signs of poisoning include vomiting, diarrhea, blindness, seizures, and tremors.
Corneal dystrophy is a condition characterized by bilateral, noninflammatory opacity of the cornea. It appears as grayish white lines, circles, or clouding of the cornea. Corneal dystrophy can also have a crystalline appearance.
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.
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.
A dog who is up to date with his vaccinations and who has been bitten by a possibly rabid animal should also be given a rabies booster vaccine immediately and kept under observation (length will vary depending on your state laws).
Rabies is a viral disease that may affect the brain and spinal cord of all mammals, including cats, dogs and humans. This preventable disease has been reported in every state except Hawaii. There’s good reason that the very word “rabies” evokes fear in people—once symptoms appear, rabies is close to 100% fatal.
If your dog will be housed outside, provide shelter such as a doghouse for when it is cold or rainy and shade for when it is hot. Protecting your dog from the changes in weather will reduce stress and help keep it healthy.

The source of the disease is unknown, with the Environment Agency ruling out any chemical contamination in water supplies. Experts believe the disease is “very similar” to Alabama Rot, thought to be related to a toxin produced by E. Coli bacteria. However, no evidence of this has been found after no signs were shown on the infected dogs.

“Be aware of it and insist a blasto test be done early,” Picken says. “It’s a small price to pay to eliminate the possibility of a tragic outcome. I found the perfect rescue dog and was ecstatic about the thought of having so many good years with him. To go from that to the heartbreak of losing him so quickly is a pretty steep fall.”
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.
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.
Ectropion (eyelid folding outward) is a common condition in dogs, usually affecting the lower lid. Breeds associated with ectropion include the Cocker Spaniel, the St. Bernard, the Bloodhound, and the Basset Hound.

Pica in dogs may be a sign of Immune-mediated hemolytic anemia, especially when it involves eating substances such as tile grout, concrete dust, and sand. Dogs exhibiting this form of pica should be tested for anemia with a Complete blood count including Hematocrit levels, or Packed cell volume.
In people, children are most often affected with roundworm. There are two forms of the disease in people. Ocular larva migrans happens when the larvae invade the retina and cause inflammation, scarring, and possibly blindness. Visceral larva migrans occurs when the larvae invade parts of the body, such as the liver, lung, or central nervous system.
Intussusception* is characterized by telescoping of one part of the gastrointestinal tract into another part, forming an obstruction. It is most common in dogs six to eight months old. Surgery is necessary for treatment.
Diabetes mellitus in dogs is type 1, or insulin dependent diabetes: a lack of insulin production due to destruction of pancreatic beta cells. Current research indicates no evidence of type 2 diabetes in dogs. Among the causes of diabetes mellitus in dogs are autoimmune disease or severe pancreatitis. Forms of diabetes which may not be permanent, depending on the amount of damage to the beta cells of the endocrine pancreas, are transient and secondary diabetes. Some causes of transient or secondary diabetes are Cushing’s syndrome, glucocorticoid, progestin or other steroid use, and the hormones of pregnancy or heat. In these cases, correcting the primary medical issue may mean a return to non-diabetic status. Common signs include weight loss, increased drinking and urination, and cataracts. Treatment involves insulin replacement therapy, and use of a diet high in fiber and complex carbohydrates. Oral diabetes medications cannot be used for dogs because none repair or surmount the permanent damage to the beta cells of the pancreas.
There has been some speculation that walking dogs in particular areas of the countryside may be a contributing factor, but the Forestry Commission has yet to warn of any specific sites being dangerous, reassuring dog owners by saying “Many thousands of dogs are walked in the countryside every day and it is important to remember that only a very small number of dogs have been affected.”
Vaccine reactions are adverse events which occur following vaccination, including granuloma formation, but most commonly the term vaccine reaction is used to describe a type I hypersensitivity reaction. The most common signs are facial swelling and hives, but more rarely very serious signs such as hypotension and collapse may occur.
Because diarrhea can easily lead to dehydration, be sure your dog has plenty of clean water available, then take your pooch to the vet if the diarrhea persists for more than a day, or immediately if there’s also fever, lethargy, vomiting, dark or bloody stools, or loss of appetite.
Leptospirosis is a zoonotic disease caused by bacteria of the genus Leptospira. Humans and dogs become infected through contact with water, food, or soil containing urine from infected animals. This may happen by swallowing contaminated food or water or through skin contact, especially with mucosal surfaces, such as the eyes or nose, or with broken skin. In dogs, transmission most commonly occurs by drinking puddle, pond, or ditch water contaminated by urine from infected wildlife such as squirrels or raccoons. The liver and kidney are most commonly damaged by leptospirosis. Vasculitis can occur, causing edema and potentially disseminated intravascular coagulation (DIC). Myocarditis, pericarditis, meningitis, and uveitis are also possible sequelae.
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.
Chocolate is a common cause of poisoning in dogs. The toxic principles in chocolate are theobromine and caffeine. Baker’s chocolate is the most dangerous form since it contains higher concentrations of these drugs, followed by semi-sweet, dark, and then milk chocolate. Signs include vomiting, diarrhea, tremors, difficulty walking, seizures, and heart problems.
Liver failure* is common. Signs include vomiting, loss of appetite, weight loss, and jaundice. Causes include bacterial or viral infection, toxic insult, cancer, copper storage diseases, or it may be idiopathic.
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.
6. Rabies: Rabies is the disease made famous in the hearbreaking scene in Old Yeller. Thankfully, the widespread use of the rabies vaccine in recent years has made its occurrence in pets in the U.S. quite rare. However, it is still present in wild animal populations, and because rabies is always fatal, it’s critical to make sure that your pets are current on their rabies vaccination.
