Grass Pollen Allergy in Dogs: Prevention and Relief

Grass pollen allergy in dogs causes skin reactions rather than sneezes. Here's how to spot it, how to test for it, and how to manage it.

Grass pollen allergy in dogs doesn’t show up as a runny nose — it shows up as itchy paws, hot spots and a miserable, scratching pet. Here’s how to manage it.

Not the same as hay fever

Grass pollen allergy in dogs is fairly common. You’d expect — since grass pollen is an inhaled allergen — that symptoms would mirror what humans experience: runny nose, sneezing, watery eyes. They don’t.

Dogs allergic to grass pollen most commonly break out in skin reactions instead.

What to look for

The signs of canine grass pollen allergy include:

  • Ear infections
  • Red, raw hot spots
  • Hair loss
  • Excessive scratching
  • Face and ear rubbing on the floor or furniture
  • Chewing on paws

If your dog is doing several of these together and the timing lines up with pollen season, grass is a likely candidate.

Confirming the diagnosis

To determine that grass pollen is the offending allergen, your dog will need veterinary testing — typically a physical examination, blood tests, and intradermal testing. Intradermal testing involves injecting various potential allergens into the skin in tiny amounts to see which ones produce a reaction. It’s the most reliable way to identify the specific trigger.

Prevention — what actually helps

Grass pollen is difficult to control entirely, but several practical measures cut exposure significantly:

  1. Keep the grass in your garden mowed short and limit your dog’s exposure to tall grasses and weeds. If possible, create an area for the dog that is primarily gravel or sand to reduce contact with grass.
  2. Wipe the dog down with a damp cloth before bringing them back inside. This removes grass pollen clinging to the fur and reduces the irritation it causes.
  3. Discourage rolling in grass. If you see the dog rolling, use a training command to stop it. Over time, this can deter the behaviour and prevent future rolls in the hay.
  4. Vacuum your home and wash dog bedding frequently to remove the pollens carried in by pets and people.

Protective boots are also a good option for dogs whose paws are the worst-affected area. Rubber boots or therapeutic paw boots keep the pollen off the paws entirely while still letting the dog go outside.

Frequently asked questions

How does grass pollen allergy show up in dogs?
Not the way it shows up in humans. Rather than runny noses or sneezing, dogs break out in skin reactions — ear infections, raw red hot spots, hair loss, and constant scratching, face-rubbing on the floor, and chewing on paws.
How is grass pollen allergy diagnosed?
Through veterinary tests including a physical examination, blood tests, and intradermal testing — where small amounts of various potential allergens are injected into the skin to identify which ones trigger a reaction.
Can grass pollen allergy be controlled?
Not eliminated, but managed. Keep grass cut short, rinse the dog’s feet and legs after going outside, keep the dog indoors when pollen counts are elevated, and consider protective boots to minimise contact with grass at the paws.
What's the fastest natural relief for an itchy, hot spot-covered dog?
Dermagic Skin Rescue Lotion for general itching and inflamed skin, and Hot Spot Salve for any raw patches. The lotion soothes and protects, the salve dries up hot spots within days while creating a protective barrier.
What can I do indoors to help?
Vacuum regularly and wash dog bedding frequently to remove grass pollens carried in on pets and people. Wipe the dog down with a damp cloth before bringing them back into the house. And discourage rolling in tall grass with a training command.
