Medical Conditions

  • 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.

  • Chronic Kidney Disease in Cats

    Los riñones tienen diferentes funciones. Su principal función es limpiar la sangre de toxinas y sustancias de deshecho, regular el nivel sanguíneo de ciertas sustancias esenciales como el sodio o el potasio, ayudar a conservar el agua del cuerpo y producir la orina.

  • 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 refers to abnormal function of a part of the kidneys called the tubules, which normally reabsorb water, electrolytes, and nutrients that are critical to normal metabolic function. In dogs with Fanconi syndrome, the tubules do not properly reabsorb electrolytes and nutrients; instead, they allow them to spill back into the urine and be expelled.

  • 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.

  • Eosinophilic granuloma complex is a term used to describe three forms of skin lesions in cats: 1) eosinophilic plaque, 2) eosinophilic granuloma and 3) indolent ulcers. These lesions have a characteristic microscopic appearance due to the presence of eosinophils, which are a form of inflammatory cell. The term is descriptive, referring to the microscopic appearance of the lesion.
