What are the different kinds of environmental allergies?

Household Allergies

The most common type of environmental allergy is called a household allergy. These are caused by the dander of the dog, cat, or other pet. The dog or cat is not usually the source of the problem, but the dander can become airborne.

When the dander is airborne, it is called an airborne allergen. The allergen can be carried on the air currents to the home and then settle on the carpet, bedding, and furniture. 

When the dog or cat is in the house, it is also possible for the dander to be in the air and cause the symptoms.

Airborne allergens can treat with antihistamines and corticosteroids.

Animal Allergies

Animal allergies are the most common form of environmental allergies in dogs. These allergies are caused by the animal dander found on the animal’s skin and hair. 

The allergy is caused by the dog’s immune system mistakenly reacting to the animal dander. Animal dander is a protein that contains protein molecules.

Some animal dander proteins are the same as human proteins. When the dog’s immune system reacts to the animal dander, it causes the dog to develop an allergy. 

The dog will sneeze, lick and scratch its face, ears, and eyes, and will have itchy watery eyes.

Allergic Rhinitis

An allergic rhinitis is a common form of rhinitis. It is a hay fever-type caused by an allergic reaction to pollen. Pollen is a plant-based allergen that is found in the air.

The most common types of pollen are grass pollen, tree pollen, weed pollen, and mold spores.

Dust Allergies

Dust allergies are the third most common type of environmental allergy in dogs. These allergies are caused by the dust that is found in the environment. Then, when the dog’s immune system reacts to the dust, it causes the dog to develop an allergy.

Cockroach Allergies
