Seasonal Allergies in Dogs: A Guide For Dog Owners

Published on 15 January 2026 at 08:00

A dog owner can manage seasonal allergies in dogs by identifying triggers early, adjusting daily routines, and seeking timely veterinary guidance when symptoms persist.

If you live in the countryside or visit it often with your dogs, you’ll already know that they absolutely love the fresh air, open fields and hedgerows. Just like us though, exposure to the countryside comes with a higher exposure to pollen, grasses, mould spores and insects, all common causes of seasonal allergies.

As a professional housesitting couple, we regularly care for dogs across Wiltshire, the Cotswolds and West Berkshire. Seasonal allergies are one of the most common health issues our clients flag to us, particularly in spring and late summer, when scratching, licking and irritated skin can quickly become uncomfortable for both dog and owner.

This guide is written for dog owners who want clear, practical advice, without fuss, on recognising and managing seasonal allergies in their dogs.

Why Seasonal Allergies Are Common in the Countryside

Seasonal allergies, sometimes referred to as atopic dermatitis, occur when a dog’s immune system overreacts to environmental allergens. In rural areas, exposure is often more intense due to:

  • High pollen counts from grasses, trees and crops
  • Damp environments encouraging mould and mildew
  • Increased contact with insects, including fleas and mites
  • Daily walks through long grass, woodland and farmland

Unlike food allergies, which tend to be year-round, seasonal allergies often follow predictable patterns linked to the farming and growing calendar.

What Are the Common Symptoms of Seasonal Allergies in Dogs?

The most common signs are skin-related and behavioural.

Dogs rarely sneeze like humans with hay fever. Instead, allergies usually show through the skin and ears.

Typical symptoms include:

  • Excessive scratching or rubbing against furniture
  • Licking or chewing paws, legs or belly
  • Red, inflamed or flaky skin
  • Recurrent ear infections or head shaking
  • Hair loss in specific areas
  • Restlessness, particularly after walks

If left unmanaged, constant scratching can break the skin, leading to infections that require veterinary treatment.

What Triggers Seasonal Allergies in Rural Dogs?

Countryside allergens differ from urban ones in both type and concentration.

Common rural triggers include:

  • Grass pollen – especially ryegrass and meadow grasses
  • Tree pollen – birch, oak and ash are frequent culprits
  • Weeds and wildflowers – nettles, ragweed and dock
  • Mould spores – common in damp barns, sheds and leaf litter
  • Insects – flea saliva is a major allergen even with low infestation

Dogs that spend long periods outdoors, work on farms, or walk daily through fields are naturally more exposed.

How Can Pet Owners Reduce Allergy Exposure at Home?

Small routine changes can significantly reduce allergen build-up.

Practical steps include:

  • Wipe paws and legs after walks using a damp cloth
  • Wash bedding weekly at a high enough temperature to remove pollen
  • Vacuum floors and sofas regularly, especially during peak seasons
  • Avoid letting dogs lie on freshly cut grass
  • Keep dogs out of barns or damp outbuildings where mould thrives

These steps don’t eliminate allergens, but they reduce the overall load on a dog’s immune system.

Should You Change Walks and Exercise Routines?

Yes, timing and location matter more than distance.

During high pollen seasons:

  • Walk dogs early morning or late evening, when pollen levels are lower
  • Avoid recently mown fields and hay meadows
  • Choose woodland tracks over open pasture during peak grass pollen months
  • Keep dogs on paths rather than allowing free running through long grass

From our experience as a mature, professional housesitting couple, small changes to walk timing alone often reduce symptoms within days.

When Should You Speak to a Vet?

Persistent symptoms should always be professionally assessed.

Contact your vet if:

  • Scratching or licking continues for more than two weeks
  • Skin becomes broken, infected or oozing
  • Ear infections recur
  • Your dog seems unsettled or uncomfortable despite routine changes

Veterinary options may include antihistamines, medicated shampoos, dietary support, or in more severe cases, immunotherapy.

Are Some Breeds More Prone to Seasonal Allergies?

Yes, genetics play a significant role.

Breeds commonly affected include:

  • Labradors and Golden Retrievers
  • West Highland Terriers
  • Spaniels
  • Bulldogs and French Bulldogs

Mixed-breed dogs can also develop allergies, particularly if they inherit sensitive skin.

A-Breed-Apart Insights

From our countryside housesitting experience:

  • Around two-thirds of dogs showing allergy symptoms reacted most strongly after walks through long grass rather than woodland
  • Paw-focused symptoms were more common than full-body itching
  • Many owners initially mistook allergies for behavioural stress

These observations highlight how closely environment and routine affect allergic reactions.

Step-By-Step: Managing Seasonal Allergies in Dogs

  1. Observe patterns – note when symptoms appear and after which activities
  2. Reduce exposure – adjust walks, wipe paws, clean bedding
  3. Maintain parasite control – fleas worsen allergic responses
  4. Support skin health – diet and gentle grooming matter
  5. Seek veterinary advice early if symptoms persist

Consistency matters more than quick fixes.
