Types of pet allergies

Of all the types of pet allergies, cat and dog allergies are very common.2 In fact, 3 in 10 people with allergies experience a reaction to cats and dogs, and cat allergies are twice as common as dog allergies.2 But any animal with fur or feathers can cause an allergic reaction — such as rabbits, guinea pigs, or ferrets.

What causes pet allergies?

Allergies happen when the immune system treats certain harmless substances as though they are allergens, which your body considers a threat. An allergic reaction to pets is caused by proteins found in animals’ saliva, urine, and dander (particles of dry skin).2 To make matters worse, your critter’s fur can collect irritants such as pollen, mold spores, and other outdoor allergens. 

When you’re exposed to these allergens, the reaction can cause itchy, irritated eyes and nasal congestion.2

Unfortunately, there’s no such thing as a dog or cat that is 100% hypoallergenic. The dander from pets that causes an allergic reaction isn’t affected by the length of fur or by how much your pet sheds,1 but rather by proteins found in animals’ saliva, urine, and dander.2

Pet allergy symptoms may include:1



Runny nose

Itchy, watery eyes*

Exposure to pet allergens can trigger other pet allergy symptoms, such as wheezing, difficulty breathing, and other respiratory symptoms.1 Some experience a skin rash, hives, eczema, or itchy skin, either as part of their symptoms or upon direct contact.*

*Nasacort® is not indicated for relieving these symptoms and should only be used as directed for nasal-allergy-symptom relief.

Tips for managing pet allergies1,2,3

Keep pets well groomed: Enlist another family member or friend to brush your furry friend daily and wash them weekly.1

Clear the air: Invest in an air purifier with a certified allergy and asthma filter.1

Designate a no-pet zone: Banish your pets from the bedroom! Then you’ll have at least one fur-and-feather-free room.1

Wash your hands: Keep your hands clean by washing thoroughly with soap throughout the day.3

Keep your house clean: Vacuum and wash throw rugs frequently, and keep surfaces throughout the home clean and uncluttered. Clean your pet’s bed and favorite furniture thoroughly and regularly.2

Try over-the-counter medication: Have an effective allergy medication on hand to relieve pet allergy symptoms, such as a nasal allergy spray.1
