Key Points
Seasonal allergies in dogs are extremely common. However, unlike people, dogs experience allergies primarily through their skin, not sneezing.
Telltale signs include excessive paw licking, persistent scratching (especially at the belly, ears, and groin), and recurring ear infections that flare during spring, summer, or fall.
Treatment ranges from simple home management like wiping paws and adding omega-3 supplements to prescription medications your veterinarian may recommend.
If you've been seeing TV commercials for dog allergy medications lately, you're not alone.
With spring flowers blooming and summer grass shooting up, seasonal allergies in dogs are a concern for many pet parents, especially those watching their pups scratch themselves raw or lick their paws constantly.
Fortunately, canine seasonal allergies are manageable. While there's no cure, most dogs can find real relief with a combination of at-home care and veterinary treatment. Here's what you need to know about recognizing, managing, and treating seasonal allergies in dogs.
What are dog seasonal allergies?
Seasonal allergies in dogs, also called atopic dermatitis or atopy, occur when a dog's immune system overreacts to harmless environmental substances like pollen, grass, mold, or dust mites. Unlike food allergies or flea allergies, seasonal allergies flare at specific times of year, typically during spring, summer, and fall, depending on your location.
The key difference between dogs and people is that dogs experience allergies primarily through their skin, not their respiratory system. While you might get a runny nose and watery eyes from pollen, your dog is more likely to develop itchy skin, ear infections, and paw-licking behavior.
Certain breeds are more predisposed to allergies, including Labrador Retrievers, Golden Retrievers, German Shepherds, Bulldogs, Pugs, Terriers, and Setters.
Throughout my years in the clinic, I’ve also noticed a strong correlation between unusual colors and skin issues. For example, that fancy lilac Bulldog, dilute blue Pit Bull, or silvery Labrador is almost guaranteed to have chronic ear infections, saliva-stained paws, or a brittle, patchy coat.
So, while you may want a dog who can spark a conversation about their unique color, be prepared to invest in quality skin care products and potential ongoing dermatological care.
Signs and symptoms of dog seasonal allergies
Recognizing seasonal allergies in dogs isn't always straightforward, since symptoms can overlap with food allergies or flea allergy dermatitis.
Food allergies cause year-round symptoms and may include gastrointestinal issues like vomiting and diarrhea. Flea allergy dermatitis is a separate condition where even a few flea bites can trigger a massive reaction.
Here are the top three telltale signs of atopic dermatitis in dogs:
Persistent itching
The hallmark symptom of allergies is nonstop itching, especially on the paws, belly, ears, armpits, groin, and around the eyes. You might notice your dog scratching constantly or rubbing their face on the carpet.
Excessive paw licking
Persistent paw licking or chewing is another major red flag. Dogs pick up allergens through their paws when they walk on grass or through pollen. If your dog's paws are always damp or stained reddish-brown from saliva, allergies are a likely culprit.
Ear infections
Chronic ear infections are extremely common in dogs with seasonal allergies. The ears become warm, red, and inflamed, often with a musty odor.
Other common seasonal allergy symptoms in dogs include:
Common dog allergy triggers
In practice, I’ve found that many pet parents are surprised by how many things can trigger an allergic reaction. Dogs are constantly picking up allergens through their paws, coat, and skin, especially after rolling in the grass, hiking wooded trails, or just lounging in the backyard. Even leaving the windows open on a breezy day can lead to itchy skin, as pollen drifts in and coats every surface.
The most common seasonal allergens include:
Tree pollen in the spring
Grass pollen in late spring and summer
Weed pollen and ragweed in the fall
Mold spores are a year-round occurrence, and they’re worse in damp conditions
Dust mites are a year-round indoor allergen
How to help your dog with allergies at home
If your dog suffers from mild to moderate seasonal allergies, you can help calm a flare or keep allergic reactions at bay with these at-home strategies:
Wipe down
Wipe paws, belly, and coat after outdoor time to remove surface pollen. The veterinarian I work for recommends making a simple “tea bath” by steeping a regular black tea bag in warm water and leaving the bowl by the door. After your dog comes inside, gently wipe their paws and belly with the cooled tea. The tannins in black tea can help soothe irritated skin, dry out hot spots, and remove allergens that may be clinging to the fur.
Bath time
Bathe regularly with hypoallergenic or oatmeal-based shampoo to remove allergens and soothe skin. Aim for once a week during allergy season. Oatmeal baths and topical coconut oil may provide comfort but won't address the underlying allergy.
Add supplements
Omega-3 fatty acid supplements (fish oil) have solid evidence for reducing skin inflammation. Check with your veterinarian on dosing.
Cleanse the air
Use a HEPA air purifier indoors to reduce airborne allergens.
Wash bedding
Wash dog bedding frequently in hot water to kill dust mites and remove pollen.
Minimize exposure
Limit outdoor time during the peak pollen hours of early morning and late afternoon.
Always check with your veterinarian before introducing new supplements or treatments.
Diagnosing seasonal allergies in dogs
If you suspect your dog has seasonal allergies, a veterinary visit is the next step. Diagnosis typically involves ruling out other conditions that can cause similar symptoms, like parasites, bacterial or yeast infections, and food allergies.
Your veterinarian will start with a thorough physical exam and may recommend skin scrapings or cytology. If food allergies are a possibility, an elimination diet trial lasting eight to 12 weeks may be suggested.
For dogs with confirmed environmental allergies, two main testing methods are available:
Blood testing: Serum testing measures your dog's immune response to specific environmental allergens. A blood sample is sent to a lab, and results indicate which pollens, molds, or other substances your dog is reacting to.
Intradermal skin testing: Intradermal testing is performed by a veterinary dermatologist and is considered more precise. Small amounts of allergens are injected under the skin to see which ones cause a reaction. This test is often used before starting immunotherapy.
Both methods help pinpoint exactly what your dog is allergic to, which can guide treatment and allergen avoidance strategies. If your veterinarian recommends in-depth diagnostic testing, learn more about dog allergy testing and what to expect.
Allergy treatment options for dogs
Once seasonal allergies are confirmed, your veterinarian can recommend a treatment plan based on symptom severity. In addition to environmental management, options may include:
OTC antihistamines: Medications like Benadryl or Zyrtec can provide mild relief for some dogs. Always consult your veterinarian before giving your dog any human medication, as proper dosing is critical.
Topical therapies: Medicated shampoos and topical treatments can help manage secondary skin infections from excessive scratching. Your veterinarian may prescribe antibacterial or antifungal shampoos or topical sprays.
Prescription anti-itch medications: Prescription medications like JAK inhibitors (Apoquel, Zenrelia, Numelvi) and injectable biologics (Cytopoint) are highly effective for many dogs with moderate to severe allergies. These work by blocking itch signals or immune responses and require veterinary prescription and monitoring.
Corticosteroids: Corticosteroids like prednisone are fast-acting for acute flare-ups but aren't ideal for long-term use due to potential side effects.
Immunotherapy: Immunotherapy, including allergy shots or drops, is the closest thing to a long-term solution. A custom treatment based on your dog’s allergy test results gradually desensitizes the immune system and can significantly reduce symptoms over time, though results may take six to 12 months.
If your dog develops ear infections or skin problems from allergies, your veterinarian will treat those as well, often with antibiotics or antifungal medications.
Managing your dog's allergies long-term
Living with a dog who has seasonal allergies takes some trial and error, but most pet parents find a routine that works. The key is starting treatment before peak allergy season to prevent symptoms from escalating.
Keep a log of when and where your dog's symptoms flare to help your veterinarian fine-tune treatment and identify specific triggers.
Managing seasonal allergies can involve regular veterinary visits, ongoing medications, and potentially allergy testing. Pet health insurance plans can help cover eligible vet bills for allergy diagnosis and treatment, so explore Pumpkin Dog Insurance plans to find the right coverage for your pup.
