Protecting Dogs and Cats Against Seasonal Allergies in Spring
October 3, 2025

Springtime in Bellevue brings blooming flowers, longer days, and warmer weather, but it also comes with pollen, mold, and other allergens. While many people prepare for sneezing and watery eyes, pets can suffer too. At Cat & Dog Clinic of Bellevue, we often see an uptick in visits during spring for itchy dogs and cats that are showing signs of allergies. 

By learning to manage spring pet allergies in Bellevue, exploring strategies for allergy prevention for cats and dogs, and finding effective ways of treating seasonal allergies in pets, you can keep your four-legged friend comfortable and healthy during the allergy season.

Why Seasonal Allergies Happen in Pets

Allergies occur when the immune system overreacts to substances in the environment. Common triggers for pets in spring include:

  • Tree and grass pollens
  • Mold spores
  • Dust and dander that increase indoors during seasonal cleaning
  • Flea bites that worsen skin sensitivity

Just like humans, pets’ bodies treat these allergens as threats, leading to uncomfortable symptoms.

Seasonal Allergies in Pets: Signs to Watch For

The signs of seasonal allergies in pets often look different than in people. Instead of sneezing or watery eyes, many dogs and cats show skin-related symptoms. Watch for:

  • Persistent scratching, licking, or chewing at paws and belly
  • Red, inflamed, or irritated skin
  • Recurrent ear infections or head shaking
  • Hair loss or thinning patches of fur
  • Excessive grooming in cats
  • Coughing or sneezing in some cases

If your pet shows these signs each spring, seasonal allergies may be the culprit. Pet MD has a post on skin allergies in dogs, which you can find here.

Spring Pet Allergies in Bellevue

The Pacific Northwest’s lush greenery and long growing seasons make spring pet allergies in Bellevue especially common. Pollen counts often rise quickly in spring, and rainy weather can increase mold growth. Dogs who spend time outdoors may carry allergens into the home, while indoor cats are still exposed when windows are open or allergens are tracked inside.

Local families should pay extra attention to pets during these months, as allergy symptoms can worsen without treatment.

Allergy Prevention for Cats and Dogs

Prevention is the first step in reducing discomfort. Some practical allergy prevention for cats and dogs includes:

  • Bathing pets with gentle, vet-approved shampoos to remove allergens from fur and skin
  • Wiping paws after outdoor walks to limit pollen exposure indoors
  • Keeping windows closed on high-pollen days
  • Washing bedding, blankets, and toys frequently in hot water
  • Using air purifiers to reduce allergens inside the home

These small adjustments can significantly improve your pet’s comfort.

Treating Seasonal Allergies in Pets

Sometimes prevention isn’t enough, and treatment becomes necessary. Options for treating seasonal allergies in pets may include:

  • Medications prescribed by a veterinarian to control itching and inflammation
  • Topical sprays, shampoos, or ointments to soothe skin irritation
  • Dietary adjustments, such as adding omega-3 fatty acids to support skin health
  • Allergy testing and immunotherapy in persistent cases

Every pet is different, so treatments must be tailored to individual needs.

When to See a Veterinarian

Persistent scratching, skin infections, or behavioral changes should prompt a veterinary visit. Left untreated, seasonal allergies can lead to secondary infections, chronic discomfort, and reduced quality of life. We can identify the cause and create a personalized plan for relief.

Fun Facts About Pet Allergies

  • Dogs often develop allergies between one and three years old, making early recognition important.
  • Cats are more likely to overgroom than scratch when dealing with itchy skin.
  • Flea allergy dermatitis is one of the most common allergic conditions seen in dogs and cats.

These facts highlight why attention to seasonal symptoms is so important.

Common Mistakes Owners Make

  • Assuming itching is caused by fleas without veterinary confirmation
  • Over-bathing pets with harsh shampoos that dry out skin
  • Ignoring early signs until symptoms worsen
  • Trying home remedies without veterinary guidance

Avoiding these mistakes helps pets get proper care faster. Click here to find another blog we’ve written on allergies.
