Dogs + Emergencies

  • Acetaminophen (Tylenol, Paracetamol, APAP, N-acetyl-p-aminophenol) is a pain relief and fever-reducing medicine people use for many types of pain. Acetaminophen is available in many forms including tablets, capsules, gel caps, melt away tablets, rectal suppositories, and liquids. Acetaminophen is often found in homes with pets. Poisoning may happen when pets get into the owner’s medications.

  • Acetaminophen (Tylenol), a common human drug used to control pain in fever, can be poisonous to dogs if inappropriate doses are given. Acetaminophen is occasionally recommended by veterinarians and should only be given under their direction. Young and small dogs have a higher risk for toxicity.

  • Acute hemorrhagic diarrhea syndrome, also known as hemorrhagic gastroenteritis, is an acute disorder of dogs characterized by vomiting and bloody diarrhea. There are several possible causes and contributing factors involved and diagnosis is often a process of eliminating other causes of bloody stools and gastrointestinal distress. Affected dogs will appear severely ill and, if left untreated, may die. In most cases, the disorder appears to run its course in a few days if the dog is given appropriate supportive care.

  • Acute respiratory distress syndrome, also known as shock lung, is a life-threatening complication of critical illness in dogs, such as systemic infection or disease, severe trauma, or near-drowning. Treatment involves targeting the underlying cause while also supporting the dog's compromised lung function with the use of an oxygen cage, an oxygen line direct to the dog's nasal passages, or in severe cases, a mechanical ventilator. Unfortunately, the prognosis for this condition is poor.

  • Ethanol overdose by ingestion, inhalation, or skin absorption leads to alcohol poisoning. Isopropanol (isopropyl alcohol/rubbing alcohol) and methanol (methyl alcohol) can also cause alcohol poisoning. If a pet is not showing clinical signs, decontamination may be performed, including inducing vomiting (for ingestions) or bathing (for skin exposure). Other therapies are discussed. Recovery is expected within 24–36 hours of the onset of signs.

  • 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.

  • Anisocoria is a condition in which the pupils of the eyes are different sizes; one pupil is larger than the other. Anisocoria is a symptom of an underlying condition or disease that needs to be identified and treated. Prognosis is guarded pending the diagnosis and treatment. Blindness may occur as a result of the underlying condition.

  • A dog that does not want to eat, or is not eating, is a dog with a potentially life-threatening medical condition. Many conditions can lead to the inability of your dog to eat or 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.

  • 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 that enable blood to clot and help control bleeding.

  • An aortic thromboembolism (ATE) results when a blood clot is dislodged and travels through the aorta, becoming lodged in a distant location. This clot causes severely reduced blood flow to the tissues receiving blood from that section of the aorta, leading to decreased oxygen in the tissues. Aortic thromboembolism is a rare occurrence in dogs and can be associated with endocarditis, cancer, sepsis, hyperadrenocorticism, and increased protein loss through diseased kidneys. This article outlines clinical signs, treatment, monitoring, and prognosis for dogs with this condition.
