Dogs + Medical Conditions

  • Dermatomyositis is hereditary, immune-mediated disease of the skin muscles and blood vessels affecting primarily collies, Shetland Sheepdogs and mixes of these breeds. Other breeds can experience similar disease. Signs are usually first recognized in puppies but can present in young adulthood. Signs include: skin lesions (crusty erosions, patchy alopecia or ulcers) around the eyes, lips, face, ear flaps or tail tip, foot pad lesions; atrophy of chewing muscles or difficulty chewing; stiff gait and megaesophagus in severely affected dogs. Skin biopsies are diagnostic. Treatment involves treating secondary bacterial infections, reducing sun exposure, EFAs, and immunomodulatory medications including tetracycline, niacinamide, pentoxifylline, cyclosporine and corticosteroids. Prognosis varies depending on severity.

  • Diabetic ketoacidosis is a medical emergency that occurs when there is not enough insulin in the body to control blood sugar (glucose) levels. It is important for your veterinarian to perform appropriate tests in order to diagnose this disease as similar signs can occur with other medical conditions. Treatment involves hospitalization with IV fluids, short acting insulin and electrolyte replacement. The most important step in prevention is ensuring proper insulin dosing is being administered.

  • Discoid Lupus Erythematosus (DLE) is an autoimmune condition that causes skin sloughing particularly around the nose causing scabbing and erosions that can become infected with bacteria. It can also affect the ear flaps, genitals and rarely spread through the entire body. DLE is diagnosed by submitting skin biopsies of affected areas for histopathological analysis. As well as antibiotics to treat secondary bacterial infections, treatment involves suppression of the immune system including tacrolimus or steroid ointments/creams applied to the affected area. Some dogs will need tetracycline and niacinamide or stronger anti-inflammatories such as cyclosporine or corticosteroids. These treatments can be weaned once lesions resolve but flare-ups will likely occur, needing rechecks and repeat therapy. Sun exposure must be minimized as UV light can worsen the disease. If untreated, lesions can develop into squamous cell carcinoma.

  • Discospondylitis is a bacterial or fungal infection of the intervertebral disks and the adjacent vertebral bones. It primarily affects dogs, though rarely can affect cats. It affects large breed dogs more often and generally starts clinically as back pain. The diagnosis and treatment of this condition are outlined in this handout.

  • An ectopic ureter is an anatomical defect that is present at birth in some dogs. In a dog with ectopic ureters, the ureters do not attach to their normal location in the bladder. Dogs with ectopic ureters may dribble urine or be prone to frequent bladder infections. Signs, diagnosis, treatment, and prognosis are discussed.

  • Evan’s syndrome is the term used when a pet has both immune-mediated hemolytic anemia (IMHA) and immune-mediated thrombocytopenia (ITP). With this condition, the body destroys its own red blood cells and platelets. Prognosis is variable and depends on the underlying cause and the pet’s general condition at the time of diagnosis. Relapses are common.

  • Facial paralysis is a condition that occurs suddenly, affecting the facial nerve. Paresis (partial paralysis) or paralysis causes weakness of facial muscles and reduced ability or inability to blink or produce tears. This handout explores causes, signs, treatment, and prognosis for this condition.

  • Fanconi syndrome affects the ability of the kidney tubules to re-absorb certain electrolytes and nutrients such as potassium and glucose, allowing them to spill into the urine. This causes excessive drinking and urination and ultimately kidney disease. Basenjis are most commonly affected. It is often diagnosed based on glucosuria without hypoglycemia. Though reversal of this disease is not possible, treatment involves supplementation with different minerals and electrolytes as well as standard treatments for management of kidney disease. Regularly monitoring of blood parameters is recommended to allow early intervention if the disease is worsening. Fanconi-like syndrome has occurred in dogs ingesting certain chicken jerky treats and can be resolved by discontinuing these treats.

  • An FHO, or femoral head ostectomy, is a surgical procedure that aims to restore pain-free mobility to a diseased or damaged hip by removing the head and neck of the femur (the long leg bone or thighbone). This procedure is commonly recommended for smaller dogs, especially those who are at a healthy weight. Active dogs often experience better results with FHO than less-active dogs. It is important to follow your veterinarian's post-operative instructions. Most dogs will show signs of complete recovery approximately six weeks post-operatively.

  • To be classified as a fever of unknown origin (FUO), the body temperature must be above 103.5°F (39.7°C) for longer than a few days, with no obvious underlying cause based on history and physical examination. A fever is beneficial to the body, but if a fever remains above 106°F (41.1°C) for more than a few days, several consequences occur within the body and can be life threatening. If your pet has a fever, your veterinarian will perform a thorough physical examination, perform diagnostic blood tests, urine culture, and possibly other diagnostic tests. Antibiotics are often prescribed.
