Emergency Situations

  • The pupil is a round opening in the middle of the iris that allows light to pass through the eye to the retina. The pupil constricts or dilates (enlarges) according to the amount of light that enters the eyes, with both pupils normally dilating in dim light and constricting in bright light.

  • 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.

  • 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. Sudden paralysis and pain, usually in the rear legs, are the most common clinical signs of aortic thromboembolism.

  • An aortic thromboembolism results from a blood clot that is dislodged and travels within 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. Aortic thromboembolism is a rare occurrence in dogs.

  • Arsenic poisoning is the accidental ingestion, skin contact, or inhalation of products containing a toxic dose of arsenic. The most common cause of arsenic poisoning in dogs is ingestion of ant baits that contain 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.

  • Aspirin is a commonly used over the counter nonsteroidal anti-inflammatory drug and is used to treat fever, pain, inflammation (swelling), and clotting disorders in humans. Aspirin poisoning occurs when a dog ingests a toxic dose of aspirin, either through misuse or accidentally. he most common side effect of aspirin is gastrointestinal irritation, which can lead to signs such as a decreased appetite, vomiting, diarrhea, and abdominal pain. Treatment for aspirin poisoning depends on how quickly the dog is seen by the veterinarian.

  • Atrial fibrillation describes very rapid contractions, or 'twitching', of the heart muscle, confined to the atria, or the top chambers. Most of the time, atrial fibrillation in cats occur secondary to heart disease.

  • Anemia is not a specific disease but rather it is a symptom of some other disease process or condition. Anemia is a medical term referring to a reduced number of circulating red blood cells (RBC's), hemoglobin (Hb), or both. Hemoglobin delivers oxygen to the cells and tissues of the body, and a patient who is anemic will suffer from symptoms related to a lack of oxygen.
