Anaphylactic Shock Symptoms in Dogs

Anaphylactic shock, or anaphylaxis, is the result of a serious allergic reaction. If not treated properly, it can lead to death. Anaphylaxis can cause serious cardiovascular and respiratory distress. This sudden reaction can be caused by virtually anything, including environmental factors, insect bites and diet.
  1. Symptoms

    • Symptoms of anaphylaxis in dogs are not the same as those in other mammals, but they are just as life threatening. They occur almost immediately after contact with the allergen. The first signs of anaphylaxis include the rapid onset of one or more of the following symptoms: vomiting, urination, itchiness, hives, diarrhea and defecation.

      If left untreated, symptoms can become more serious and may include fatigue, cold limbs, elevated heart rate, weakness, difficulty breathing, drooling, shallow breathing, weak pulses, excitement and depression.

    What to Do

    • If anaphylactic shock is not treated in a timely manner, a dog will almost always have a seizure and collapse. This may result in coma or death. Get your dog to the vet right away if you see any of the symptoms stated above. Once your dog has been treated, try to identify what caused the anaphylaxis so you can avoid a reaction in the future.

    Common Causes

    • Dogs are hypersensitive to insect bites and vaccines. Those who spend the majority of their time outside are especially likely to get insect bites and bee stings -- leaving them at a high risk for severe allergic reactions. Environmental causes can be dust, pollen or anything else your dog can inhale. Many owners find that their dogs diets can cause hives and itching, too. Fillers in dog foods can set off off such reactions. If this happens, switch your dog to an organic dog food.
