It’s allergy season for humans, and many of us are carrying tissues and rubbing itchy, swollen eyes. But did you know that your pet could be suffering from allergies, too?

Environmental allergens, like the things that bloom at this time of year, can bother your pet, and there are several other things you might not realize they can be allergic to as well.

We talked with Dr. Andrea Lam, Clinical Assistant Professor of Dermatology at the Cummings School of Veterinary Medicine at Tufts University, to find out about pet allergens — and how we can help our furry friends cope.

But first, how can you tell if allergies are getting to your pet? “Itching is the main symptom,” says Dr. Lam. “However, pets show they are itchy in a variety of ways. Dogs and cats will scratch, rub against furniture, shake their heads or overgroom.”

If you notice your pet is doing these things, you should talk to your your vet. She can help diagnose what’s causing the signs and potentially run some basic lab tests to check for secondary yeast or bacterial infections (a common problem for allergic pets) as well as prescribe the appropriate treatments to help relieve itching and/or treat the infection, says Dr. Lam.

Below, take a look at a handful of things you might not have realized your cat or dog could be allergic to.

  • cat itching
  • dust, dustpan and broom
  • dog eating from bowl
  • dog rolling in grass
  • cat and dog

What Could Your Pet Be Allergic To?

House Dust Mites

Do you sneeze when your home is dusty? House dust mites are another common allergen for our pets. Avoidance, long-term medications or desensitization through allergy shots are possible solutions, says Dr. Lam.

Seasonal Allergies

Pollens, molds and other environmental allergens can bother your cat or dog, too. “Pets with seasonal allergies can be treated both with long-term medications, or they can be desensitized to their allergens through allergen-specific immunotherapy (allergy shots), just like in people,” Dr. Lam explains.

Other Pets and People

Much like we can be allergic to cat or dog dander, humans have dander that our pets can be allergic to as well. And cats and dogs can even be allergic to each other’s dander. There is a different allergen in felines, known as the fel D1 protein. It is often found in saliva and oil gland secretions and likely plays a role in canine allergies to cats, too, Dr. Lam says. If allergy tests show your dog or cat is allergic to you, allergy shots are a long-term medical option.
