Seasonal Allergies in Dogs: Signs, Causes, and How to Help
As a vet, one of the most common issues I see each spring and summer is dogs struggling with itchy skin, irritated paws, or constant scratching. Much like people, dogs can suffer from seasonal allergies, triggered by environmental allergens such as pollen, grass, mould, or dust mites.
These allergies can develop at any age and often worsen over time. While rarely dangerous, they can cause considerable discomfort if left untreated.
Recognising the Signs of Seasonal Allergies
Dogs with environmental allergies usually show symptoms through their skin rather than their respiratory system.
Common signs include:
● Persistent scratching, licking, or chewing at the paws, belly, or ears
● Red, inflamed, or flaky skin
● Recurrent ear problems
● Hair loss or thinning patches from over-grooming
● Rubbing the face or body along furniture or the ground
Because these symptoms can also be caused by fleas, food sensitivities, or infections, it’s important to have your dog examined by a vet for an accurate diagnosis.
What Causes Seasonal Allergies in Dogs?
Seasonal allergies occur when the immune system overreacts to otherwise harmless environmental substances. Common triggers include:
● Tree, grass, and weed pollens
● Mould spores
● Dust mites
● Fleas or flea saliva
Some breeds, such as Retrievers, Terriers, and Bulldogs, are genetically more prone to allergic skin disease, but any dog can be affected.
Managing and Treating Seasonal Allergies
Allergies can’t be cured, but they can be successfully managed with the right combination of home care and veterinary support.
1. Minimise allergen exposure
Wiping your dog’s paws, belly, and legs after walks can reduce pollen build-up. Regular vacuuming and washing bedding also help limit dust and mould exposure indoors.
2. Bathing and grooming
Using a mild, vet-approved shampoo can remove surface allergens and soothe irritated skin. Frequent brushing helps distribute natural oils and supports the skin barrier.
3. Flea prevention
Even small numbers of fleas can make allergies worse. Keep up with year-round prevention as advised by your vet.
4. Nutritional support
A balanced diet containing essential fatty acids can strengthen the skin barrier and reduce inflammation. Some dogs benefit from veterinary diets formulated for skin health.
5. Veterinary treatment
If home measures aren’t enough, your vet can discuss options tailored to your dog’s needs. These may include short-term relief for itching and inflammation or longer-term strategies such as prescription diets or desensitisation therapy. Because every dog’s allergy profile is different, professional guidance is vital before starting any treatment.
When to See Your Vet
If your dog is persistently itchy, losing fur, or developing repeated ear or skin infections, it’s time to seek veterinary advice. Early management prevents secondary infections and chronic discomfort.
With a personalised plan, most dogs can stay comfortable and enjoy the outdoors without constant scratching - no matter the season.
