The pancreas is an organ near the stomach and small intestine that produces enzymes needed for digestion, as well as hormones such as insulin that regulate blood sugar levels. Dogs with exocrine pancreatic insufficiency (EPI) are unable to digest nutrients in their diet properly, resulting in maldigestion, weight loss, and abnormal feces than can appear unusually pale and fatty. The disease can be congenital, genetic (such as in German shepherds), or acquired through pancreatic damage. Prognosis is good with treatment, although rarely diabetes is associated with the condition.

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 short faced (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 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.

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.
