  • Anal sac tumors grow quickly and have a moderate risk of spreading to other parts of the body. Depending on the tumor’s size, your pet could develop signs of straining to defecate or produce thin ribbon-like stool. An increased calcium level in the blood is consistent with anal sac tumors, which can cause other signs and result in kidney failure. The best and most well-described local treatment for the primary tumor is surgery. Radiation and chemotherapy may be considered if there is evidence of spread.

  • 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 tick-borne disease caused by the infectious bacterial organism Anaplasma phagocytophilum. It is transmitted through bites of the deer tick (also known as the black-legged tick) and the Western black-legged tick. A lesser form of anaplasmosis is caused by Anaplasma platys and is transmitted by the brown dog tick. Dogs with anaplasmosis often have many of the same symptoms as those with Lyme disease, and infection with both agents (co-infection) is not uncommon.

  • Hailing from Turkey, the Anatolian Shepherd Dog was bred to guard livestock. The breed is not well-known outside of his native land, except to fanciers. Guarding instincts are highly developed and can be misplaced if owners are not aware of this.

  • 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.

  • Anesthesia is accomplished by administering drugs that depress nerve function. It is important that you fully understand what will happen to your pet, and that you acknowledge that you understand the risks. Anesthetic monitoring in a veterinary hospital is similar to that found in any human hospital. With today's anesthetics, many of which are reversible, your pet should be almost completely normal by the time of discharge.

  • Anisocoria is a condition in which the pupils of the eyes are different sizes; in other words one pupil is larger than the other. Anisocoria is a sign of an underlying disease condition, therefore there are several different causes. Your veterinarian will begin by conducting a physical examination of your dog, including a detailed examination of the structures of the eye. The treatment and prognosis of anisocoria depend entirely on the underlying cause of the condition, and treatment will be tailored specifically to the diagnosis.

  • A dog that is not wanting to eat or is not eating, is a dog who has a potentially life-threatening medical condition. Many conditions can lead to the inability of your dog to eat or for your dog to lose his appetite completely. It is important to find the underlying cause so that an appropriate treatment plan can be created. Appetite stimulants may be prescribed and in some cases a feeding tube may be placed by your veterinarian. Decreased food intake or any change in eating habits warrants investigation by your veterinarian.
