There’s something special about watching your dog sniff their way through spring grass or your cat bask in a warm summer breeze. But when seasonal allergies hit, those peaceful moments can turn into weeks of scratching, licking, and discomfort. If your pet seems extra itchy or unsettled this time of year, you’re not alone—and you’re not without options.

At Twin Lakes Veterinary Hospital, we’ve walked with many Orillia pet parents through the ups and downs of seasonal allergies. We understand the frustration (and the worry) of watching your pet struggle, and we’re here to help you find answers—and relief.

What Are Seasonal Allergies, Really?

Seasonal allergies (technically known as atopic dermatitis) happen when your pet’s immune system overreacts to something in their environment—often something harmless, like pollen or mold spores. The result? Inflammation, itching, and discomfort that can make even the calmest pet feel miserable.

Unlike food allergies or flea bites, seasonal allergies tend to flare up during certain months—typically spring and summer here in Ontario, when pollen and other allergens are at their peak. Learn more about different types of allergies from the AKC.

What’s Causing It?

There’s no single answer, but some common triggers include:

  • Tree and grass pollen
  • Mold spores from leaves, mulch, or damp ground
  • Dust mites
  • Insect bites or stings
  • Fleas, which can make seasonal allergies worse

Some pets have a genetic predisposition, meaning their breed or family history makes them more susceptible. Others may develop allergies over time, especially if their immune system or skin barrier is compromised.

Year-round parasite prevention is especially important—because even a few flea bites can escalate allergy symptoms fast.

How Do I Know If It’s Allergies?

It’s not always obvious. But here are some of the signs we see most often in allergic pets:

Common Symptoms

  • Itchy skin (especially paws, belly, ears, and underarms)
  • Excessive licking or chewing at certain spots
  • Red or irritated skin
  • Hair loss or patchy fur
  • Frequent ear infections or head shaking
  • Sneezing or coughing (more common in cats)
  • Restlessness or irritability—especially when itching interrupts sleep

Even mild symptoms can affect your pet’s mood and comfort. Over time, untreated allergies can cause deeper issues, including skin infections, thickened skin, and chronic inflammation.

What If We Don’t Treat It?

We get it—mild allergies can feel manageable at first. But unfortunately, they tend to get worse with time. Pets may start scratching more aggressively, damaging their skin and opening the door for secondary infections like yeast or bacteria.

You may also see:

  • Ear infections that keep coming back
  • Behavior changes from lack of sleep or chronic discomfort
  • Increased risk of food sensitivities due to a “leaky” skin barrier

Catching allergies early—and managing them proactively—can make a huge difference for your pet’s long-term health.

How We Diagnose Seasonal Allergies

When you come in for an allergy consultation, we start with a thorough physical exam and a discussion of your pet’s history, home environment, diet, and lifestyle.

Depending on what we find, we may recommend:

  • Skin cytology (a look under the microscope for infection or inflammation)
  • Skin scrapings to rule out mites or other parasites
  • Ear swabs if infections are present
  • Allergy testing (blood or intradermal) to identify specific triggers

We’ll always walk you through the why behind every test—and tailor our plan to what’s best for you and your pet.

Treatment: What Relief Looks Like

We approach allergy care from multiple angles, depending on your pet’s symptoms and triggers:

Medical Treatments

  • Antihistamines – mild and often effective for early symptoms
  • Corticosteroids – powerful relief during flare-ups (used short-term)
  • Cytopoint® or Apoquel® – targeted medications to stop the itch
  • Immunotherapy – allergy shots or drops designed to “retrain” the immune system

Topical Therapies

  • Medicated shampoos to remove allergens and calm inflamed skin
  • Leave-on sprays or mousses
  • Ear cleaners to prevent secondary infections

Nutrition & Supplements

  • Omega-3 fatty acids to reduce inflammation
  • Hypoallergenic or limited-ingredient diets
  • Skin barrier supplements (like vitamin E or ceramides)

Daily Routines That Can Help

Sometimes small changes at home make the biggest difference:

  • Wipe your pet’s paws after walks to remove pollen
  • Avoid peak pollen times for outdoor activities (early morning or windy days)
  • Use air purifiers and keep windows closed during high pollen days
  • Wash bedding weekly and vacuum often
  • Consider frequent bathing (with vet-recommended products)

Preparing for Your Appointment

Before your visit, jot down:

  • When the symptoms started and how they’ve changed
  • Photos or videos of skin, licking, or ear behavior
  • A list of food, treats, medications, and supplements
  • Any questions you want to ask (we love when clients come prepared!)

Questions like:

  • What allergens are most likely in our area?
  • Can we treat this at home—or is medication needed?
  • How long will it take for my pet to feel better?
  • Will my pet need lifelong care?
