Dogs + Medical Conditions

  • Bladder stones can be a significant problem for dogs. Bladder stones set the stage for chronic urinary tract infection, and some bladder stones (struvites) grow more quickly if the dog already has a urinary tract infection. Diet selection can play a role, and it is important to follow your veterinarian’s recommendations to prevent recurrence.

  • In North America, obesity is the most common preventable disease in dogs. Almost 50% of domestic dogs are overweight. Scientific evidence now reveals that fat tissue is biologically active; it secretes inflammatory hormones and creates oxidative stress on the body's tissues, both of which contribute to many diseases and decreased quality of life. Treating obesity as a chronic, low-level inflammatory condition is the new approach.

  • Open fontanelles are soft spots in the skull, or gaps between the skull’s growth plates. They can be normal in young puppies, especially small breeds, and typically close or harden by 9-12 weeks of age. This handout discusses causes, diagnosis and treatment of open fontanelles in small breed puppies.

  • Rarely, ovarian tissue can be left behind when a dog is spayed. This leads to the ongoing secretion of hormones such as estrogen and progesterone that can result in a dog continuing to have a heat cycle. Ovarian remnants are difficult to diagnose, but vaginal cytology combined with hormone testing can be used to confirm the presence of functional ovarian tissue. Surgical treatment is typically recommended to prevent other health conditions from developing.

  • The pancreas is a vital organ that produces enzymes to assist in food digestion and hormones such as insulin, which regulates blood sugar or glucose metabolism. Pancreatitis is inflammation of the pancreas. Common clinical signs include decreased appetite, nausea, vomiting, lethargy, diarrhea, and abdominal pain. Diagnosis is generally made with laboratory testing and/or abdominal ultrasound. Successful pancreatitis management will depend on early diagnosis and prompt medical therapy. The prognosis depends on the severity of the disease and the response to initial therapy.

  • Pancreas-specific lipase is a form of lipase produced only in the pancreas and is highly specific to the pancreas. Blood values increase only when there is pancreatic inflammation. A version of the cPLI test can now be used in-clinic (SNAP fPL© from IDEXX). Ideally, the sample should also be sent to the laboratory to get an actual value of cPLI to help with treatment and monitoring.

  • Panniculitis is a localized inflammation of the tissues under the skin, causing a firm swelling (nodule) that may ulcerate and drain fluid. It is a common problem in cats and is less common in dogs. There are several causes of panniculitis, but in younger animals with a single lump, the cause is often blunt trauma and, in cats, it is often caused by bite wounds from fighting. An accurate diagnosis relies on the microscopic examination of tissue and the most common treatment is the surgical removal of the lump(s).

  • Chronic superficial keratitis (CSK), or pannus, is a potentially blinding disease affecting the cornea. Any dog breed can be affected by pannus, but it is predominantly seen in German shepherds, Belgian shepherds, and border collies. Diagnosis is based on medical history and clinical signs. Treatment involves using topical corticosteroids or other immune-modulating drugs. If diagnosed early and treatment plans are followed, many dogs can have a good prognosis and live a normal life.

  • Panosteitis is a painful inflammation of the outer surface or shaft of one or more long bones of the legs. It is sometimes called growing pains. Panosteitis is a condition that affects young, rapidly growing dogs. Panosteitis will be suspected if the patient shows pain when pressure is applied to the affected bone(s). The diagnosis is confirmed by X-rays, which usually show a characteristic increase in the density of the affected bones. Although this disease will spontaneously resolve, during episodes of lameness the condition is very painful. At these times, treatment is supportive, using pain medication and anti-inflammatory drugs as needed.

  • Papillomas are benign, sometimes multiple, tumors caused by viruses. They are commonly known as warts. The virus is transmitted through direct contact from an infected pet or the pet’s environment (e.g., toys, food bowls, or bedding) and gain access to the body when the skin becomes softened by moisture, through cuts and abrasions, or with the assistance of insects. Pets with immature immune systems such as young dogs and puppies, and those that are immune compromised, are more prone to developing papilloma tumors. The tumors often disappear within 1-2 months because the animal slowly develops an immunity to them. However, sometimes they persist, and surgical removal is necessary.
