Medical Conditions

  • 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.

  • A feather cyst is a malformation of a feather follicle whereby the feather(s) do not exit the skin, and instead become buried in a cyst under the skin. They can become quite large and be painful to the pet. These cysts require veterinary attention and if injured, may bleed extensively.

  • Feather loss occurs either because the bird is truly losing feathers or because the bird, or its cage-mate, is picking out its feathers. Feather Destructive Behavior (FDB) is a general classification that describes the many types of damage a bird can do to its own feathers, including feather picking. Feather loss and feather-picking can also be caused by diseases that result in irritation or pain for the bird, or damage to, or inappropriate growth of feathers. Feather loss and feather-picking are complicated problems. For specific advice, your bird should have a thorough work-up by a veterinarian familiar with birds.

  • 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 cats, especially those who are at a healthy weight. Active cats often experience better results with FHO than less-active cats. It is important to follow your veterinarian's post-operative instructions. Most cats will show signs of complete recovery approximately six weeks post-operatively.

  • 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.

  • There are several common diseases or conditions that may affect the pet ferret. Like dogs, ferrets may get heartworms, distemper virus, heat stroke and a variety of cancerous conditions. Yearly veterinary health examinations are recommended to assess the presence or absence of any of the diseases listed above.

  • 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.

  • Fibrocartilaginous embolus (FCE) or fibrocartilaginous embolic myelopathy (FCEM) refers to a condition caused by a piece of fibrocartilaginous material thought to originate from an intervertebral disc, lodging in an artery or vein, causing decreased blood flow to an area of the spinal cord. Confirmatory diagnosis requires MRI. Treatment is primarily supportive.

  • Fibrocartilaginous embolus (FCE) or fibrocartilaginous embolic myelopathy (FCEM) refers to a condition caused by a piece of fibrocartilaginous material thought to originate from an intervertebral disc, lodging in an artery or vein, causing decreased blood flow to an area of the spinal cord. This condition is more common in younger, large-breed dogs; however, certain small breeds and all ages can be affected. Confirmatory diagnosis requires MRI. Treatment is primarily supportive. Recurrence is unlikely.
