Have you ever wondered if dogs can have allergies? Did your veterinarian tell you to avoid certain areas and food items just because your dog might be allergic to them? If so, then you might have a lot of questions in your head regarding the same. Don’t worry, we are here to enlighten you, so you can make wise, informed decisions.


Let’s start with understanding what allergies are and their causes.

What is an allergy?

It is the overreaction of the immune system to a particular external substance, called an allergen. Meaning if your dog’s immune system thinks that pollen is something that is not supposed to be entering the body, it causes a reaction against it. This leads to an allergic reaction; usually, these reactions are unnecessary.

When your dog is exposed to allergens, it triggers an immune response in their body that leads to the release of histamine. The unnecessary release of too much histamine can cause your dog a lot of discomfort including inflammation, itching, and swelling. There can be various reasons that can cause an allergic reaction in your dog; most allergens are proteins from plants, insects, animals, or foods.
