Just like people, pets can develop seasonal allergies that cause discomfort, itching, and other frustrating symptoms. As the seasons change in Texas, many pets begin to experience allergic reactions to pollen, mold, dust, and other environmental irritants. Unlike humans, who often suffer from sneezing and congestion, pets frequently exhibit allergies through skin irritation, ear infections, and excessive scratching.

At High Point Animal Hospital, we help pet owners understand, manage, and treat allergies in dogs and cats. Identifying the symptoms early and taking proactive measures can make a significant difference in your pet’s comfort and overall health.

What Are Seasonal Allergies in Pets?

Seasonal allergies, also known as atopic dermatitis, occur when a pet’s immune system overreacts to allergens in the environment. These allergens are often harmless but cause an exaggerated immune response in sensitive pets.

Common Environmental Allergens

  • Tree, grass, and weed pollen (especially in spring and fall)
  • Mold spores (common in damp environments)
  • Dust mites and household dust
  • Flea saliva (can trigger flea allergy dermatitis)
  • Chemical irritants (such as cleaning products, perfumes, or air fresheners)

Some pets are more prone to developing seasonal allergies than others. Certain breeds—including Labrador Retrievers, Golden Retrievers, French Bulldogs, and Siamese cats—tend to be more genetically predisposed to allergic reactions.

Signs and Symptoms of Seasonal Allergies in Pets

Recognizing early allergy symptoms can prevent discomfort and complications like skin infections, ear infections, and hot spots.

Skin and Coat Symptoms

  • Persistent itching, scratching, or chewing at the skin
  • Red, inflamed skin or rashes
  • Hair loss or thinning fur
  • Hot spots (areas of irritated, infected skin)
  • Dry, flaky skin (especially on the belly, paws, or armpits)

Ear and Paw Symptoms

  • Frequent head shaking or scratching at the ears
  • Recurrent ear infections
  • Excessive licking or chewing on paws
  • Swollen, red, or sensitive paw pads

Respiratory Symptoms

  • Sneezing or coughing
  • Watery or red eyes
  • Nasal discharge or congestion
  • Reverse sneezing (common in small dog breeds)

If your pet’s symptoms persist or worsen, a veterinary evaluation is necessary to rule out other conditions like parasites, bacterial infections, or food allergies.

Diagnosing Seasonal Allergies in Pets

Because allergy symptoms can overlap with skin infections, fungal conditions, and autoimmune disorders, proper diagnosis is key. At High Point Animal Hospital, we take a comprehensive approach to identifying and managing allergies.

Veterinary Diagnostic Methods

  • Physical examination – Evaluating skin health, ears, and coat condition
  • Skin cytology tests – Identifying secondary bacterial or yeast infections
  • Allergy testing – Blood tests or intradermal skin testing to pinpoint allergens
  • Elimination diet trials – Used to differentiate food allergies from seasonal allergies

Allergy testing is particularly useful for pets with chronic, severe symptoms that do not respond to routine management.

Treatment Options for Seasonal Allergies

1. Medications to Control Allergy Symptoms

  • Antihistamines – Help reduce itching and mild allergic reactions
  • Corticosteroids – Provide relief from severe inflammation (used short-term)
  • Prescription allergy medications – Apoquel and Cytopoint target allergic reactions at the source
  • Allergy-specific immunotherapy (ASIT) – Allergy shots designed to desensitize the immune system

For pets with severe, chronic allergies, immunotherapy may be the most effective long-term solution.

2. Topical and At-Home Treatments

  • Medicated shampoos – Help wash allergens off the skin and soothe irritation
  • Omega-3 fatty acid supplements – Strengthen the skin barrier and reduce inflammation
  • Ear cleaners – Prevent secondary ear infections caused by allergies
  • Hypoallergenic pet wipes – Clean paws and fur after walks to remove pollen

Explore the benefits of regular pet grooming from the ASPCA.

3. Environmental Management and Prevention

  • Keep pets indoors during peak pollen hours (early morning and evening)
  • Wipe down paws and fur after outdoor activities to reduce allergen buildup
  • Vacuum frequently and use HEPA air purifiers to minimize indoor allergens
  • Wash pet bedding and toys regularly to remove dust mites and pollen

For small pets, ensure bedding is changed frequently, and keep enclosures free from dust and mold buildup.

When to See a Veterinarian

If your pet’s allergy symptoms are persistent, severe, or leading to infections, veterinary care is necessary. Signs that require a visit to the vet include:

  • Excessive scratching or licking that leads to sores
  • Persistent ear infections or head shaking
  • Hair loss, red skin, or thickened patches of skin
  • Respiratory distress, wheezing, or difficulty breathing

Untreated allergies can result in chronic pain, infections, and reduced quality of life. A customized allergy treatment plan from High Point Animal Hospital can provide lasting relief.
