While many of us are familiar with the sneezing, congestion, and itchy eyes that come with the change in weather, few realize that our pets can also suffer from allergies. At North Shore Veterinary Hospital, we see a surge in cases each spring and summer as pets react to allergens like pollen, mold, and grasses. If your dog or cat seems uncomfortable lately, they may be dealing with more than just spring fever.

Understanding Pet Allergies

Unlike humans, who typically express allergies through respiratory symptoms, pets often exhibit signs on their skin. Itchy, inflamed skin (a condition called allergic dermatitis) is one of the most common ways that dogs and cats react to seasonal allergens. Other symptoms can include:

  • Excessive scratching or licking
  • Red or irritated skin
  • Hair loss or thinning fur
  • Recurring ear infections
  • Watery eyes or sneezing
  • Scooting or licking anal areas

These symptoms can range from mild to severe, and may be mistaken for fleas or general discomfort. If symptoms persist or worsen, it’s important to consult your veterinarian.

What Causes Allergies in Pets? The main culprits are environmental allergens, including:

  • Tree pollen (common in early spring)
  • Grass pollen (late spring to summer)
  • Mold spores (especially after spring rain)
  • Dust and dander buildup from being indoors all winter

Some pets are also sensitive to insect bites, particularly from fleas and mosquitoes, which become more active in warmer weather.

To diagnose allergies your pet will need a thorough exam covering questions about your pet’s environment, behavior, and health history. Depending on the case, we may recommend skin testing or blood tests to identify specific allergens. Sometimes, ruling out other causes (like food allergies or parasites) is necessary to arrive at an accurate diagnosis.

Treatment Options Fortunately, there are several ways to help manage seasonal allergies in pets. Some common treatments include:

  • Antihistamines or corticosteroids: To reduce inflammation and itchiness.
  • Medicated shampoos and wipes: Help soothe irritated skin and remove allergens from the coat.
  • Allergy injections or oral immunotherapy: Custom treatments that help your pet build resistance to specific allergens.
  • Flea control: Essential to reduce itching and prevent secondary infections.
  • Dietary support: Omega-3 fatty acids and other supplements can help improve skin health and immune response.

Home Care Tips for Pet Allergy Relief

  • Wipe your pet’s paws and coat with a damp cloth after walks.
  • Vacuum frequently and use HEPA filters to reduce indoor allergens.
  • Bathe your pet regularly (with vet-approved shampoos).
  • Wash bedding and toys weekly.
  • Keep windows closed during high pollen days.
