Seasonal Allergies in Dogs and Cats: Causes, Symptoms, and Relief

Home » News » Seasonal Allergies In Dogs And Cats Causes Symptoms And Relief

If your pet is scratching more than usual, licking their paws, or has watery eyes, they might be dealing with seasonal allergies. Just like humans, dogs and cats can react to pollen, mold, and other allergens in the environment. Knowing what causes allergies, how they develop, and the signs to look for can help you keep your pet comfortable during allergy season.

What Causes Seasonal Allergies in Pets?

Seasonal allergies happen when a pet’s immune system overreacts to things like pollen from trees, grass, and weeds, as well as mold and fungi. These allergens are most common in certain seasons:

Spring: Tree pollen
Summer: Grass pollen
Early Fall: Weed pollen
Year-round: Mold and fungi (depending on where you live)

When pets encounter these allergens – either by breathing them, touching them, or even licking them off their fur – their bodies react, leading to allergy symptoms.

How Do Allergies Develop?

A pet’s immune system is designed to fight off harmful substances, like bacteria and viruses. But with allergies, the immune system mistakenly sees something harmless—like pollen—as a threat. This leads to inflammation, itching, and other allergic reactions.

Some pets only have allergies during certain times of the year, while others may have reactions year-round. In some cases, seasonal allergies can get worse over time, leading to more serious symptoms.

Signs Your Dog or Cat Has Seasonal Allergies

If your pet has allergies, you might notice:

Excessive itching: Scratching, biting, or licking their paws and body
Skin irritation: Redness, rashes, or hair loss from scratching
Ear infections: Red, inflamed, or smelly ears
Eye problems: Watery, red, or swollen eyes
Sneezing and runny nose: Like humans, pets can have cold-like symptoms

Dogs often get skin and ear infections due to allergies, while cats may show more respiratory issues like sneezing and watery eyes.

How to Help Your Pet Feel Better

There are several ways to reduce allergy symptoms and keep your pet comfortable:

Regular baths: Washing your pet removes pollen and soothes itchy skin. Talk to your veterinary team about a shampoo that won’t dry your pet’s skin.
Medication: Talk to your vet about antihistamines or other treatments to reduce itching and swelling.
Allergy shots (immunotherapy): This long-term treatment helps your pet’s immune system get used to allergens over time.
Clean environment: Use air purifiers, wipe your pet’s paws after outdoor walks, and wash their bedding often.

If your pet has allergy symptoms, a visit to your vet for advice on treatment options can set you up for success. Allergies cannot be cured, but can be managed successfully. With the right care, your furry friend can stay happy and comfortable all year long.
