Introduction
When most people hear the term ‘anaphylactic shock’ they think of the allergic reaction that produces swelling in the throat and bronchial airways in people. Anaphylactic shock can occur in dogs as well, but due to the way the condition affects dogs their symptoms are vastly different. While the symptoms may differ, anaphylactic shock in dogs is just as much of an emergency situation as in people.
Symptoms of Anaphylactic Shock in Dogs
The allergic anaphylactic reaction in people causes swelling of the bronchial airways because the reaction first attacks the lungs. In dogs, the reaction goes straight to the liver. As a result, the symptoms of anaphylactic shock in dogs are focused on gastrointestinal signs. These symptoms will develop within minutes, or up to one hour, after the dog has been exposed to the allergen.
The first signs of anaphylactic shock in dogs are normally sudden and severe diarrhea and vomiting. These symptoms are quickly followed by shock symptoms which include: pale gums, a rapid heart rate, shallow but rapid breathing, cold limbs, and a decrease in mental clarity. If untreated, the anaphylactic shock will lead to seizures, coma, and then death.
Dogs suffering from an anaphylactic episode normally do not display respiratory distress or swelling around the throat or face. If the condition is caused by an allergen that entered through the skin, such as a bee sting or injected medication, than swelling or bruising may appear around the site.
If you notice anaphylactic shock symptoms in your dog, take your dog to a veterinarian or emergency clinic immediately. The reaction can rapidly deteriorate in minutes into a life threatening condition if it is not immediately treated.
