Just like humans, dogs can suffer from seasonal allergies—and in a climate like Québec’s, where seasons bring drastic environmental changes, many pets experience discomfort that often goes unnoticed. For dog owners across the province, knowing the signs, causes, and ways to relieve seasonal allergies is key to keeping your furry friend comfortable and healthy year-round.
In this guide, we’ll cover what seasonal allergies are, how they affect dogs, the specific allergens common in Québec, and what pet parents can do to prevent and treat flare-ups effectively.
Understanding Seasonal Allergies in Dogs
Seasonal allergies in dogs—also known as atopic dermatitis or environmental allergies—are hypersensitive reactions to allergens like pollen, mold spores, grass, and dust mites. While some dogs have allergies all year, many only show symptoms during certain seasons when specific allergens are more prevalent.
Unlike humans, who often experience sneezing and watery eyes, dogs typically exhibit allergies through skin irritation. You might notice your dog scratching more, licking its paws, or developing red, inflamed skin.
Why Some Dogs Are More Prone
Certain dog breeds are genetically more predisposed to developing allergies. Breeds like Boxers, Golden Retrievers, Labrador Retrievers, Bulldogs, Terriers, and Poodles tend to be more susceptible. However, any dog—regardless of breed or age—can develop seasonal allergies.
Common Allergens in Québec
Québec’s varied climate and rich biodiversity mean that different allergens are present depending on the time of year. Here’s a breakdown of the most common allergens by season:
Spring (April–June)
-
Tree pollen: Birch, maple, oak, and elm trees release pollen that can trigger allergic reactions.
-
Mold spores: As snow melts and humidity increases, mold growth on dead leaves and organic debris can spike.
Summer (June–August)
-
Grass pollen: Kentucky bluegrass and ryegrass are common allergens for dogs in Québec.
-
Insect bites: Fleas, mosquitoes, and black flies can provoke allergic skin reactions.
Fall (September–November)
-
Weed pollen: Ragweed is one of the most aggressive fall allergens, peaking in late August through September.
-
Mold: As leaves decay, mold spores return in high numbers.
Winter (December–March)
-
Indoor allergens: Dust mites and mold in poorly ventilated homes may cause symptoms to persist indoors during the colder months.
Symptoms of Seasonal Allergies in Dogs
Recognizing the signs early can help you intervene before your dog’s discomfort becomes severe. Keep an eye out for the following symptoms:
-
Itchy skin (pruritus): Constant scratching, chewing, or biting, especially around the paws, belly, armpits, and ears.
-
Red or inflamed skin: Hot spots or irritated areas that may become infected.
-
Excessive licking: Particularly of the paws, which may become stained brown from saliva.
-
Ear infections: Recurring infections, head shaking, or scratching at the ears.
-
Watery eyes or nasal discharge
-
Hair loss or thinning fur
-
Respiratory issues (less common): Sneezing or coughing in response to airborne allergens.
Some of these symptoms can also indicate food allergies, parasites, or other medical conditions, so it’s important to consult your veterinarian for a proper diagnosis.
Diagnosing Allergies in Your Dog
A veterinarian may suspect allergies based on clinical signs and seasonal patterns. They may perform:
-
Skin tests: Intradermal allergy testing is similar to human allergy tests.
-
Blood tests: To identify antibodies to specific allergens.
-
Elimination trials: Used primarily for food allergies but may help rule out other causes.
Your vet may also recommend ruling out parasites like fleas or mites, which can mimic allergy symptoms.
Treatment Options
There’s no “cure” for seasonal allergies, but there are many effective ways to manage your dog’s symptoms.
1. Medications
-
Antihistamines: Like Benadryl or Reactine (under veterinary guidance) can help mild symptoms.
-
Steroids: Prescribed for short-term relief in severe cases, though not recommended long-term.
-
Immunotherapy: Allergy shots tailored to your dog’s specific triggers can help desensitize their immune system over time.
-
Apoquel & Cytopoint: Prescription medications designed to target itching and inflammation caused by allergies with fewer side effects than steroids.
2. Topical Treatments
-
Medicated shampoos: Anti-itch or antifungal shampoos can soothe irritated skin.
-
Paw soaks: Rinsing your dog’s paws after walks can reduce allergen buildup.
-
Balms or creams: For hot spots or dry, cracked skin.
3. Environmental Management
-
Regular bathing: Once a week with a gentle, hypoallergenic shampoo can wash away allergens.
-
Wipe-downs: Use a damp cloth to clean your dog’s coat and paws after outdoor play.
-
Air purifiers: Help reduce indoor allergens during high pollen seasons.
-
Vacuum frequently: Especially if your dog spends time on furniture or rugs.
-
Leash control during high pollen days: Keeping your dog on a short, secure leash helps avoid unnecessary contact with grasses and plants that may trigger reactions.

Natural Remedies & Supplements
Some pet parents in Québec prefer more natural approaches, especially for mild allergies. Always consult your vet before introducing supplements:
-
Omega-3 fatty acids: Found in fish oil, help reduce inflammation and promote skin health.
-
Coconut oil: May relieve itching when added to food or applied topically.
-
Quercetin: A natural antihistamine found in apples and kale.
-
Probiotics: Support gut health, which is closely linked to immune response.
Preventing Seasonal Allergies
While you can’t prevent your dog from ever being exposed to allergens, you can reduce their impact by:
-
Keeping your lawn trimmed to limit pollen exposure.
-
Walking during low-pollen times, such as early morning or after rainfall.
-
Using washable bedding and washing it weekly in hot water.
-
Sealing windows during high pollen months to limit allergens indoors.
The Impact of Climate Change in Québec
Climate change has begun to affect pollen seasons across Canada, including Québec. Warmer temperatures and extended growing seasons mean longer pollen seasons—and worse symptoms for allergic pets.
According to recent studies, ragweed season in Québec has lengthened by nearly three weeks over the past few decades. That means dogs who previously only had mild symptoms may now need more consistent allergy management.
When to See a Vet
If your dog shows any of the following signs, it’s time for a veterinary consultation:
-
Scratching or licking becomes constant or obsessive.
-
Open sores, scabs, or signs of skin infection appear.
-
Symptoms do not improve with at-home treatments.
-
Your dog seems lethargic, loses appetite, or shows behavioral changes.
What Québec Pet Owners Should Specifically Watch For
In Québec, each season brings unique risks and challenges. Here are a few region-specific tips for pet parents:
-
Watch for road salt in winter, which can irritate already sensitive paws.
-
Be cautious in humid spring and fall months, when mold grows rapidly in forests, parks, and backyards.
-
Choose allergy-friendly trails or parks—some areas are known for ragweed or grass pollen concentrations.
-
Ask your vet about flea prevention year-round, especially if you travel to warmer parts of Canada or the U.S. with your pet.
