Dogs get hay fever too — but instead of sneezing, they itch. If your dog scratches more in spring or fall, seasonal allergies are a likely culprit.
Seasonal allergies in dogs are usually environmental (pollen, grass, mold) and, unlike in people, show up mainly as itchy skin, ears, and paws rather than sneezing. They flare at predictable times of year. Relief ranges from bathing and wiping down after walks to vet-prescribed medication like Apoquel or Cytopoint for dogs whose itch disrupts their life.
Dogs get hay fever — but it shows on the skin
Here's what surprises owners: seasonal allergies in dogs rarely cause the sneezing you'd expect in a person. Instead they itch — paws, ears, belly, face — and get recurrent ear infections, worse at predictable times of year. If your dog reliably flares each spring or fall, seasonal allergy is the likely culprit even without a single sneeze.
Get ahead of the season
Because the timing is predictable, you can prepare. Start the cheap defenses — post-walk wipe-downs, more frequent bathing, flea control — before the season peaks rather than after your dog is already miserable. Owners who plan ahead often need less medication than those who react once the itch is in full swing.
When NOT to reach straight for the strong stuff
Do not use the strongest prescription as a first reflex for a mild seasonal flare, and avoid human allergy pills without veterinary direction — they're not the right choice on your own and the dose isn't a guess. Save the prescription options for when the simple measures aren't enough; your vet decides.
Seasonal cost planning
The upside of seasonal allergies: you may only need medication for part of the year. The prep layer is cheap; when a vet prescribes something like Apoquel for the peak weeks, a vet-reviewed pharmacy is usually cheaper than the clinic. We list prices openly so you can plan around the season.

How seasonal allergies look in dogs
Itching, licking, chewing, recurrent ear infections, and red or irritated skin — worse at certain times of year. The face, paws, belly, and ears are common hot spots. [1]
Simple things that help
Wiping paws and coat after walks, regular bathing with a gentle shampoo, and keeping the home clean reduce the pollen load on your dog.
When to involve a vet
If the itch is constant or causing skin damage, a veterinarian can confirm allergies and prescribe medication such as Apoquel (oclacitinib) to control it. The right choice and dose are veterinary decisions.
Frequently asked questions about seasonal allergies in dogs
Can I give my dog Benadryl for allergies?
Sometimes it helps mild cases, but it's not right for every dog and the dose isn't a guess — ask your vet.
Do seasonal allergies go away?
They tend to recur each season, so management is ongoing rather than a one-time fix.
