Every spring, dog owners notice the same pattern — more scratching than usual, paws being chewed, a face being rubbed along the carpet. It is easy to attribute this to the heat, insects, or simply a quirk of the season. But for many dogs, what is actually happening is an allergic response to the same airborne pollen that causes hayfever in their owners.
Yes, dogs can get hayfever — though what it looks like in dogs is quite different from the sneezing and streaming eyes we associate with the condition in people. Understanding the signs helps you recognise it sooner, manage it more effectively, and avoid months of unnecessary discomfort for your dog.
How Seasonal Allergies Work in Dogs
Like humans, dogs can develop allergic sensitisation to airborne allergens including grass pollen, tree pollen, mould spores, and dust mites. The immune system identifies these harmless particles as threats and mounts an inflammatory response. In dogs, however, this response manifests primarily through the skin rather than the respiratory tract.
The condition is more accurately termed canine atopic dermatitis or canine atopy, and it is one of the most common allergic conditions seen in veterinary practice. Certain breeds are genetically predisposed — including Labrador and Golden Retrievers, Bulldogs, Boxers, West Highland White Terriers, and German Shepherds — though any dog can develop atopic disease.
Signs Your Dog May Have Hayfever
The symptoms of seasonal allergy in dogs tend to be most pronounced during spring and summer, correlating with peak pollen periods. The most common signs include:
Persistent scratching
Particularly around the face, ears, armpits, groin, and between the toes. The itching is often intense and can lead to redness, hair loss, or broken skin if left unmanaged.
Chewing or licking paws
One of the most characteristic signs of environmental allergy in dogs. Pollen settles on the paws during walks and is absorbed through the skin, triggering a localised allergic response. Repeated licking causes the fur between the toes to turn a reddish-brown colour from saliva staining — a telltale sign.
Rubbing the face
Dogs with facial irritation will rub their muzzle and eyes against furniture, carpets, or the ground. Redness around the eyes and muzzle is common.
Recurring ear infections
Allergic inflammation in the ear canal creates conditions in which yeast and bacterial infections thrive. Dogs with atopy often present with recurrent otitis externa — a pattern that persists until the underlying allergy is managed.
Sneezing or watery eyes
Less dominant than in humans, but some dogs do show mild respiratory or ocular signs during high pollen periods.
Skin redness, hot spots, or rashes
Particularly in skin folds and on the abdomen. Chronic scratching can lead to thickened, darkened skin over time if the allergy is left unaddressed.
Is It Pollen or Something Else?
Seasonal allergies are not the only cause of itching in dogs, and distinguishing between them matters for treatment. Flea allergy dermatitis is the most common cause of skin disease in UK dogs and produces a very similar picture — intense itching, particularly around the base of the tail and lower back. Food allergy is another important differential, typically causing year-round rather than seasonal symptoms but occasionally difficult to separate from environmental allergy without a structured elimination diet trial.
The seasonal pattern is the most useful distinguishing feature of pollen allergy. If symptoms begin each spring, worsen through summer, and improve significantly in autumn and winter, environmental allergens — most likely pollen — are the probable cause. A vet can help confirm this and rule out the other common differentials.
What Can You Do to Help?
- Wipe paws after every walk. A damp cloth or pet-safe wipe used on your dog’s paws, legs, and underbelly after outdoor time removes pollen before it is absorbed or licked off. This simple step makes a meaningful difference for many atopic dogs.
- Bathe regularly during pollen season. Bathing every one to two weeks with a veterinary-recommended shampoo removes accumulated pollen from the coat and provides temporary relief from skin irritation. More frequent bathing can dry the skin, so follow your vet’s guidance on frequency.
- Keep grass short in your garden. Freshly cut grass releases significantly more pollen than long grass. Mowing regularly, or keeping your dog away from areas of freshly cut grass, reduces exposure during peak periods.
- Maintain rigorous flea control. Even a single flea bite can trigger a significant response in an allergic dog and will compound existing pollen allergy symptoms. Year-round, veterinary-prescribed flea treatment eliminates one major variable.
- Speak to your vet about medical management. Options have expanded considerably in recent years and now include targeted anti-itch medications that provide rapid, effective relief with a favourable safety profile. A vet assessment is the most direct route to getting your dog comfortable.
Frequently Asked Questions
- Do dogs sneeze from hayfever?
Some dogs do sneeze in response to pollen, but respiratory symptoms are much less dominant in dogs than in humans. The primary presentation in dogs is skin-based — itching, paw chewing, and ear problems are far more characteristic of canine pollen allergy than sneezing.
- Which dog breeds are most prone to hayfever?
Certain breeds have a known genetic predisposition to atopic dermatitis, including Labrador Retrievers, Golden Retrievers, West Highland White Terriers, Boxers, Bulldogs, and German Shepherds. However, any breed can develop environmental allergies, and mixed-breed dogs are not immune.
- Can I give my dog antihistamines for hayfever?
Some antihistamines are used in dogs under veterinary guidance, but human formulations should never be given without veterinary advice — some contain ingredients such as xylitol that are toxic to dogs. Antihistamines also tend to be less effective in dogs than in humans for controlling atopic symptoms. A vet can advise on whether they are appropriate and at what dose.
- Will my dog’s allergies get worse each year?
Canine atopy often does progress over time, with sensitisation extending to additional allergens and symptoms becoming more pronounced as the dog ages. Early veterinary involvement and consistent management generally produce better long-term outcomes than waiting until symptoms are severe before seeking help.
- When should I take my dog to the vet for allergy symptoms?
A vet assessment is advisable if your dog is scratching to the point of causing broken skin or hair loss, has recurring ear infections, is visibly uncomfortable for more than a few days, or if over-the-counter measures are not providing adequate relief. Early management prevents secondary infections and skin changes that are harder to treat once established.
