  • 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 are lined with a large number of sebaceous (sweat) glands that produce a foul smelling fluid.

  • 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.

  • Anal glands are located on either side of the anus and normally produce secretions that are pushed when feces is evacuated from the rectum. An anal sac tumor is a tumor of made up of cells originating from the glands of the anal sac. These tumors can spread and therefore staging is recommended prior to surgery. To diagnose these tumors, a fine needle aspirate can be placed from the outside and into the anal sac to retrieve cells. After surgery, chemotherapy may be considered. Radiation therapy has also been considered as a primary or secondary treatment option.

  • Anaphylaxis is an acute severe allergic reaction caused by an overreaction of the body’s immune system to an allergen such as a food protein, medication, vaccine antigen or other chemical. The most common signs include itching, cutaneous edema, hives, excessive drool, vomiting, diarrhea or respiratory distress. Diagnosis is made based on history and physical exam.

  • Anaplasmosis is a disease that affects dogs, but can also affect people. It rarely affects cats. Multiple species of ticks can transmit the disease. Diagnosis is relatively simple and treatment is effective.

  • Anemia is a medical term referring to a reduced number of circulating red blood cells, hemoglobin, or both. It is not a specific disease but rather it is the result of some other disease process or condition. The most easily observed and common clinical sign of anemia is a loss of the normal pink color of the gums. Several tests are performed on blood samples to diagnose anemia. If your cat's anemia is so severe that it is life threatening, a blood transfusion will be needed.

  • Anemia has a wide variety of causes and appropriate treatments based on the specific cause. Signs of anemia include the loss of the normal pink color of the gums, loss of energy or stamina, weight loss, labored breathing, loss of appetite, a faster than normal heart rate, or signs of blood loss. Several tests are performed to diagnose anemia and additional testing may be required to determine the specific cause. Toxins, infectious diseases, or cancer are some possible causes. Prognosis is variable depending on the underlying cause and how early anemia is diagnosed.

  • The word anesthesia comes from the Greek meaning "lack of sensation". Anesthesia is accomplished by administering drugs that depress nerve function. With general anesthesia, the patient is made unconscious for a short period. During this unconscious state, there is muscular relaxation and a complete loss of pain sensation.
