Medical Conditions

  • Addison’s disease is caused by the decreased release of the hormones cortisol and aldosterone from the adrenal cortex. Most commonly caused by immune-mediated destruction, Addison’s disease can also be caused by trauma, infection, neoplasia or hyperadrenocorticism treatment. Clinical signs are non-specific and often come and go. Common signs include lethargy, vomiting, diarrhea, increased thirst and urination, and weight loss. Some patients present in an Addisonian crisis which includes severe weakness, severe vomiting and diarrhea and requires immediate medical intensive care in hospital. Addison’s is diagnosed using history, bloodwork, urinalysis, and ultimately an ACTH stimulation test. Addison’s is treated by administering synthetic replacements for aldosterone and cortisol. Prognosis is good once dogs have been stabilized on medication.

  • Hypoadrenocorticism, also known as Addison’s disease, is a condition in which the adrenal glands do not produce enough glucocorticoids (steroids) to allow normal body function. This condition is considered rare in cats, but numerous cases have been reported. Affected cats often have a history of waxing and waning periods of lethargy, decreased appetite, and weight loss. Long-term, cats with hypoadrenocorticism require medications to supplement the substances released from the adrenal glands.

  • One of the most common medical conditions affecting cats is allergy. Flea allergy, food allergies, atopy, and contact allergies are examples of allergies in cats, with flea allergy being the most common cause. Flea allergy is a response to proteins or antigens present in the flea's saliva, and just one fleabite may cause such intense itching that the cat may severely scratch or chew itself, leading to the removal of large amounts of hair. Food allergy testing is conducted by feeding an elimination or hypoallergenic diet. If your cat's symptoms improve after the food trial, a presumptive diagnosis of food allergy is made.

  • An allergy is a state of over-reactivity or hypersensitivity of the immune system to a particular substance called an allergen. Most allergens are proteins from plants, insects, animals, or foods. In the dog, the most common symptom associated with allergies is itching of the skin, either localized (in one area) or generalized (all over the body). The symptoms of allergies can be confused with other disorders, or occur concurrently with them. Therefore, do not attempt to diagnose your dog without veterinary professional assistance.

  • One of the most common conditions affecting cats is allergy. An allergy occurs when the cat's immune system "overreacts" to foreign substances called allergens or antigens. Allergens and antigens are simply foreign proteins that the body's immune system tries to remove.

  • Most people know someone who is allergic to certain foods, such as strawberries or nuts. Food allergy is one of the five most common allergies or hypersensitivities known to affect dogs. In a pet with an allergy, the immune system overreacts and produces antibodies to substances that it would normally tolerate.

  • Amyloidosis occurs when amyloid proteins are deposited outside of cells in various tissues and organs causing tissue and organ dysfunction. It is uncommon in cats, except for Abyssinians, Siamese, Burmese, Tonkinese, Devon Rex, and Oriental Shorthair breeds. Signs depend on the organs involved, but kidney involvement is most common. If kidneys are involved signs include mouth ulcers, weight loss, vomiting, and dehydration. For cats with liver involvement, signs include weakness, pale gum color, distended abdomen, rapid heart rate, rapid breathing, abdominal pain, and collapse. There is no specific medication for the treatment of amyloidosis in cats, with treatment focusing on kidney support.

  • Amyloidosis occurs when amyloid proteins are deposited outside of cells in various tissues and organs, causing tissue and organ dysfunction. It is uncommon in dogs, except in Beagles, Chinese Shar Peis, Collies, Treeing Walker Hounds, and English Foxhounds. Signs depend on the organs involved, but kidney involvement is most common. If kidneys are involved signs include mouth ulcers, weight loss, vomiting, and dehydration. For dogs with liver involvement, signs include weakness, pale gum color, distended abdomen, rapid heart rate, rapid breathing, abdominal pain, and collapse. There is no specific medication for the treatment of amyloidosis in dogs, with treatment focusing on kidney support. Shar Peis may be treated with colchicine to reduce the effects of amyloid deposition.

  • The anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. The walls of the sac produce a foul smelling fluid which is released whenever the cat passes a bowel movement. The anal sacs or their ducts can become inflamed or infected due to a variety of causes. Most cats will respond well to pain relief medications and antibiotics (for several days until the swelling and inflammation have subsided. If a cat has several episodes of anal sac disease, and diet or supplements do not relieve the problem, the anal sacs can be removed surgically.

  • Commonly called 'anal glands', the anal sacs are two small pouches located on either side of the anus at approximately the four o'clock and eight o'clock positions. Numerous specialized sebaceous (sweat) glands that produce a foul smelling secretion line the walls of the sacs. Each sac is connected to the outside by a small duct that opens just inside the anus.
