Emergency Situations

  • 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.

  • Anorexia (a loss of appetite) and lethargy (a feeling of listlessness and general inactivity) are commonly seen in sick pet birds. While not diagnostic for any specific disease, these signs can indicate severe illness in a bird that requires immediate medical attention. Birds rarely get sick overnight. Usually birds are ill before pet owners notice outward signs of illness.

  • A cat that is not wanting to eat or is not eating, is a cat who has a potentially life-threatening medical condition. Many conditions can lead to the inability of your cat to eat or for your cat to lose her 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.

  • Anticoagulant rodenticides are poisons used to kill mice, rats, and other rodents by preventing blood clotting. Poisoning occurs when a cat ingests rodenticide. Anticoagulant rodenticides cause excessive bleeding by interfering with vitamin K1 recycling in the body. Vitamin K1 is needed for the body to make certain clotting factors which enable blood to clot and help to control bleeding.

  • Anticoagulant rodenticide is used to kill mice, rats, and other pests. Poisoning occurs when a dog ingests rodenticide accidentally. Anticoagulant rodenticides cause excessive bleeding by interfering with vitamin K1 recycling in the body. Vitamin K1 is needed for the body to make certain clotting factors which enable blood to clot and help control bleeding.

  • An aortic thromboembolism results when a blood clot is dislodged and travels through the aorta, becoming lodged in a distant location. This causes severely reduced blood flow to the tissues receiving blood from that particular part of the aorta, leading to decreased oxygen in the tissues. Mixed breed cats, Abyssinian, Ragdoll, and Birmans are the most commonly affected. Sudden paralysis and pain, usually in the rear legs, are the most common clinical signs of aortic thromboembolism, although weakness and lameness may be seen. Other signs may include decreased or absent pulses in the femoral arteries of the rear legs, rapid breathing or difficulty breathing, vocalization from pain, vomiting, and the nailbeds and footpads may be pale or bluish. Initially, cats may need to be treated as inpatients. Drugs to prevent platelets from clumping together will be prescribed. The expected course of this disorder is days to weeks for full recovery of function to the legs, but the prognosis in general is very poor.

Aortic thromboembolism is a rare occurrence in dogs and can be associated with can be associated with endocarditis, cancer, sepsis, hyperadrenocorticism, and with increased protein-loss through diseased kidneys.

  • Arsenic poisoning is the accidental ingestion, skin contact, or inhalation of products containing a toxic dose of arsenic. Clinical signs can include abdominal pain, salivation, vomiting, diarrhea, staggering, weakness, rapid weak pulse, lethargy, low body temperature, collapse, and death. Supportive therapy is a crucial part of treating arsenic poisoning.

  • Aspirin is a commonly used over the counter nonsteroidal anti-inflammatory drug (NSAID) and is used to treat fever, pain, inflammation (swelling), and clotting disorders in humans. Aspirin poisoning occurs when a cat ingests a toxic dose of aspirin, either through misuse or accidentally. Clinical signs depend on how much aspirin was eaten. Treatment for aspirin poisoning depends on how quickly the cat is seen by the veterinarian.
