Epiphora or excessive tearing from the eyes can be a sign of tear duct blockage or more serious eye problems. Clinical signs include dampness beneath the eyes, reddish-brown staining of the fur beneath the eyes, odor, skin irritation, and skin infection. The facial anatomy of brachycephalic breeds may play a role in this condition. Treatment may include flushing of the nasolacrimal duct, or surgery to open the lacrimal puncta. The prognosis is variable and dependent on whether the underlying cause can be found and treated.

Ectropion, or outward rolling of the eyelid, can cause problems such as recurring conjunctivitis and drying out of the cornea. The clinical signs are a "sagging" or outward-rolling lower eyelid, although ectropion can affect any of the eyelids. A thick mucoid discharge often accumulates along the eyelid margin. Diagnosis is usually made on physical examination. Testing for hypothyroidism and for antibodies against certain muscle fibers may be done if looking for underlying causes. The treatment for mild ectropion generally consists of medical therapy; if the condition is severe, surgical correction can be performed to shorten the eyelids.

Entropion, or rolling in of the eyelids, is seen in many breeds and is considered a hereditary disorder. Most dogs will squint, hold the eye shut, and tear excessively (epiphora), though some patients will develop a mucoid discharge. Entropion can cause additional eye problems, such as corneal ulcers, perforations, or development of pigment on the cornea interfering with vision and chronically irritating to the dog. Entropion is corrected with surgery.

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.

False pregnancy refers to a display of maternal behaviors, combined with the physical signs of pregnancy following estrus, in unspayed female dogs that are not actually pregnant. Signs include physical and behavioral changes, outlined in this article. Mild cases typically are not treated, but treatment may be needed for more serious cases. If your dog is not used for breeding, spaying is recommended.

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.

Feline idiopathic cystitis (FIC) includes a set of clinical signs associated with abnormal urination and is the diagnosis when there is no identifiable cause of the clinical signs. Cats often suffer waxing and waning of symptoms such as straining to urinate, blood in urine, and inappropriate urination. Treatment and prognosis are discussed.

This handout provides information on Feline Immunodeficiency Virus (FIV) in cats. Included is information on how the disease is transmitted, the clinical signs, the recommendations for isolation of the infected cats, and potential treatment guidelines should your cat be infected with this virus.
