Anaphylactic Reactions

Anaphylactic reactions are severe and potentially fatal allergic reactions. Have you ever seen a person suddenly swell up or nearly die from eating peanuts because he was allergic to them? Or somebody suddenly rushed to the hospital after he had eaten a lobster because he was allergic to seafood? These are examples of anaphylactic reactions, which can cause life-threatening reactions within minutes.

Anaphylactic reactions in dogs can sometimes occur when your dog is stung by a bee or a wasp or due to a certain medication or when they react to certain medications or vaccines. According to The Spruce Pets, the excessive amounts of histamines in the body during an anaphylactic reaction may lead to low blood pressure, difficulty breathing, and narrowing of airways—bringing the body into a shock.
