Valley fever is an infection called Coccidioidomycosis, caused by the soil-dwelling fungus Coccidioides immitis. In the US, it is more commonly found in the southwestern states. Dogs are infected by inhaling spores released by disturbance of soil. These spores infect the lungs, forming spherules, and may migrate to different areas of the body, including the bones, joints, eyes, and rarely the brain. Dogs with weakened immune systems can become ill. Most dogs that are treated appropriately will recover from this disease.

Vestibular disease is when a cat suddenly develops incoordination, falling or circling to one side, involuntary darting of the eyes back and forth, a head tilt, and often nausea or vomiting. Most cases are idiopathic, meaning the exact cause is unknown. Idiopathic vestibular disease is a short-term, self-resolving condition with a good prognosis.

Vestibular disease refers to a sudden, non-progressive disturbance of balance. It is more common in older dogs. Clinical signs include a head tilt, loss of balance, and nystagmus. Causes of vestibular disease include middle or inner ear infections, drugs that are toxic to the ear, head trauma or injury, tumors, and hypothyroidism. This article discusses signs, diagnosis, treatment, and prognosis for dogs with this condition.

Too much vitamin A can lead to poisoning. While somewhat uncommon in North America, vitamin A toxicity is sometimes diagnosed in cats that are fed primarily table scraps. There seems to be considerable variability in how susceptible individual cats are to this problem. It takes a long time for the clinical signs associated with vitamin A toxicity to develop; symptoms do not usually appear until the cat is at least middle-aged.

Vitamin D poisoning occurs when a cat ingests a toxic dose of vitamin D. A common source of vitamin D poisoning is when a cat accidentally ingests rodenticides containing vitamin D. The initial clinical signs of poisoning occur anywhere from 8 to 48 hours after ingestion and include depression, weakness, and appetite loss. Vomiting, increased drinking and urination, constipation, and dehydration typically follow these signs.

Vomiting may be caused by disorders of the stomach, but is a clinical sign that can occur with many diseases and problems. Different types of vomiting are reviewed. Any required tests are determined based on physical examination of your cat and questions regarding how your cat has been acting and feeling at home.

Vomiting is the forceful evacuation of stomach contents. It is a clinical sign of a disease. Most cases of acute vomiting resolve quickly with simple treatment, without the underlying cause being diagnosed. Any required tests are determined based on physical examination of your pet and the signs your dog has been displaying at home.

Von Willebrand's disease causes an inability for blood to clot resulting in excessive bleeding. If this disease is suspected, initial screening tests include a complete blood count (CBC), buccal mucosal bleeding time, and a coagulation profile. More advanced diagnostics include assays that assess the quantity and functionality of vWF. DNA testing is available and most commonly used to evaluate animals used in breeding programs.
