As the seasons change on Long Island, so do the allergens that can affect our pets. Dogs and cats, just like humans, can suffer from seasonal allergies, but they often show symptoms in ways that differ from us. Here’s a breakdown of what to expect during each season and how to help your pets manage their allergies.

Spring: Tree Pollens and Mold

Common Allergens

• Tree Pollen: Early spring sees high levels of pollen from trees such as oak, maple, and birch.
• Mold Spores: Increased rainfall and humidity can lead to mold growth, which becomes a significant allergen during the spring months.

Symptoms in Pets

During spring, pets may begin to show signs of atopic dermatitis, such as itching, licking their paws, or rubbing their faces. Dogs often develop red or inflamed skin, and cats may cough, sneeze, or overgroom, leading to bald patches.

What You Can Do

• Wipe your pet’s paws after walks to remove pollen and mold.
• Bathe your pet more frequently (e.g. weekly) using hypoallergenic shampoo.
• Keep your windows closed when possible, and use air purifiers to reduce pollen in the home.

Summer: Grass Pollens and Dust Mites

Common Allergens

• Grass Pollen: Late spring to early summer brings an increase in grass pollens, particularly from species like Kentucky bluegrass and ryegrass.
• Dust Mites: Dust mites thrive in warm, humid environments and can affect pets throughout the summer months.

Symptoms in Pets

If your pet suffers from seasonal allergies, summer is when symptoms can escalate. You may notice your pet scratching more than usual, chewing on their paws, or developing hot spots (painful, inflamed areas of skin). Cats may exhibit coughing or sneezing along with excessive grooming.

What You Can Do

• Avoid walking your pet during peak pollen times (early morning and late afternoon).
• Keep grass in your yard trimmed and clear away any leaves or debris that may harbor allergens.
• Use a dehumidifier to reduce moisture in the air and minimize dust mites.

Fall: Weed Pollens and Mold

Common Allergens

• Weed Pollen: As summer ends, weed pollens (such as ragweed) peak, and this can affect pets during late summer into early fall.
• Mold Spores: Mold continues to be a problem during the fall, especially in areas with fallen leaves or damp conditions.

Symptoms in Pets

By the time fall rolls around, pets may continue to struggle with itchy, inflamed skin or persistent ear infections. Dogs may lick their paws or rub their faces excessively, while cats may overgroom or develop bald patches. If allergies are not treated, these symptoms can lead to secondary infections or even hair loss.

What You Can Do

• Remove fallen leaves and debris around your home to reduce mold exposure.
• If your pet spends more time outside, make sure to wipe down paws and coat after walks.
• Avoid walking during peak pollen times to limit exposure to allergens.

Winter: Year-Round Triggers (Dust Mites and Mold)

Common Allergens

• Dust Mites: Although outdoor allergens decrease, dust mites can still be a problem in your home, especially during colder months when pets are indoors more.
• Mold Spores: In areas with high humidity or moisture, mold can continue to be a significant allergen year-round.

Symptoms in Pets

During winter, pets with allergies may continue to experience symptoms such as itching, redness, or skin irritation, though they may be more noticeable because of less outdoor activity.

What You Can Do

• Use air purifiers to reduce indoor allergens like dust mites and mold.
• Wash pet bedding and vacuum regularly to keep the environment clean and allergen-free.
• Consider bathing your pet more frequently to help remove allergens from their coat.
