Dog Allergies in Spring: UK Complete Guide 2026

Why Spring Allergies Are a Growing Problem for UK Dogs

For many UK dog owners, spring brings more than longer walks and sunshine -it brings the start of months of scratching, licking, and discomfort for their pets. Canine allergies are now one of the most common reasons for veterinary appointments in the UK, and spring triggers are the single biggest category.

Unlike humans, who typically show hay fever symptoms in the nose and eyes, dogs most commonly react through their skin. This is called atopic dermatitis -an allergic response where the skin barrier becomes inflamed, itchy, and vulnerable to infection. The skin of an allergic dog is like a house with a leaky roof: once the barrier is compromised, everything gets in.

The good news? With the right knowledge, spring allergies are manageable. This guide covers the causes, symptoms, management strategies, and how DogWalkWeather can help you plan walks that minimise your dog's exposure to allergens.

Common Spring Allergens in the UK

Tree Pollen (March to May)

The spring allergy season in the UK typically begins with tree pollen, peaking between March and May. Tree pollen counts are highest on warm, dry, windy days -conditions that are becoming more common in UK springs due to climate change.

Common allergenic trees in the UK:

Birch -the most common UK tree allergen; affects dogs who live near parks and residential streets
Oak -widespread across UK woodland; pollen season overlaps with birch
Ash -common in urban areas and countryside
Hazel and alder -early spring allergens, typically January to March

How to recognise tree pollen allergies in dogs:

Itchy front paws (dogs lick and chew paws because pollen settles there)
Itchy face and ears (facial pruritus)
Redness between toes
Ear infections that recur in spring

Grass Pollen (May to August)

Grass pollen is the most common allergen for UK dogs overall. In the UK, grass pollen season typically runs from May through August, peaking in June and July. This overlaps with peak tick season and the warmest walking weather -making spring and summer a challenging time for sensitive dogs.

Grass allergens affect dogs through:

Direct contact during walks
Inhalation during outdoor activities
Transfer from fur to skin when dogs lie on grass

Symptoms specific to grass allergies:

Belly and groin itching
Underarm (axilla) redness
Licking of private areas
generalised itching after walks in grassy areas

Weed Pollen (June to September)

Weed pollen extends the allergy season through summer and into early autumn. Common UK allergenic weeds include:

Plantain -widespread, especially on disturbed ground
Nettle -common in woodland edges and parks
Dock -found near paths and in grasslands
Mugwort -more common in southern England

Recognising Allergy Symptoms in Your Dog

Early Signs (What to Look For)

Dogs rarely show sudden severe reactions to allergens. Instead, allergies develop gradually over days and weeks of exposure. The first signs are often subtle and easily mistaken for normal behaviour.

Early warning signs:

Behaviour	What It Might Mean
Chewing or licking paws	Pollen trapped between toes
Scratching ears or shaking head	Ear inflammation from allergens
Rubbing face on furniture or carpet	Facial skin irritation
Red or brown staining between toes	Persistent licking from itch
Thin fur or bald patches on tail or legs	Self-trauma from scratching
Excessive grooming	Attempting to remove allergens

Moderate to Severe Signs

When allergies are left unmanaged, the skin barrier breaks down further, leading to secondary problems:

Hot spots -localised areas of raw, infected skin from obsessive scratching
Yeast infections -warm, moist ears and paws are breeding grounds for Malassezia
Bacterial skin infections -broken skin allows bacteria to enter
Skin thickening -chronic inflammation causes the skin to become leathery and dark
Behavioural changes -constant discomfort leads to irritability, restlessness, and poor sleep

When to See a Vet

Allergy management is a veterinary responsibility. Here is when you should book an appointment:

See your vet if your dog:

Scratches so much it disrupts sleep or daily life
Has broken skin, hot spots, or signs of infection
Is constantly chewing paws to the point of redness or bleeding
Has recurring ear infections (more than 2 per year)
Shows signs of hives, facial swelling, or breathing difficulty (possible anaphylaxis -emergency)

What the Vet Might Do

Veterinary allergy management may include:

Skin and coat examination -to assess damage and rule out other conditions
Skin scrapes or cytology -to identify secondary infections
Food elimination trial -to rule out food allergies (food allergies cause year-round symptoms, not just spring)
Allergy testing -intradermal skin testing or blood tests to identify specific allergens
Immunotherapy -a long-term desensitisation treatment (allergy shots) tailored to your dog's specific allergens
Medication -Apoquel, Cytopoint (monoclonal antibody injection), antihistamines, or short-term corticosteroids

Managing Spring Allergies: A Practical Guide

Walk Timing and Planning

The most effective non-medical strategy for spring allergies is smart walk timing.

Allergen exposure follows predictable patterns:

Time of Day	Pollen Count	Recommendation
Early morning (6-8am)	High	Grass pollen rises with morning dew
Midday to afternoon	Highest	Warm air holds pollen close to ground
Late afternoon (5-7pm)	Still high	Pollen settles slowly after peak
After rain	Lowest	Rain washes pollen from the air
Evening (after 8pm)	Lower	Cooler air, less turbulence

Best strategy: Walk your allergic dog after heavy rain or during light drizzle. The DogWalkWeather app shows hourly rain probability and pollen risk forecasts -use it to plan around the driest, cleanest windows.

Post-Walk Care Routine

For dogs with confirmed spring allergies, a consistent post-walk routine is essential:

Step 1: Paw wipe-down

Wipe your dog's paws with a damp cloth or pet-safe wipe after every walk. Pollen clings to paw pads and between toes and is a major source of ongoing exposure.

Step 2: Face and belly rinse

Use a pet-safe allergy wipe or damp cloth to wipe your dog's face, chin, and belly -areas where pollen settles during walks.

Step 3: Coat brushing

Brush your dog's coat after every walk to remove pollen trapped in fur. Long-haired breeds need extra attention.

Step 4: Ear check

Dogs with spring allergies are prone to ear infections. Check ears for redness, discharge, or smell after each walk. Clean ears with a vet-approved solution if needed.

Step 5: Omega-3 supplement

Omega-3 fatty acids (EPA and DHA) improve skin barrier function and reduce inflammation. Fish oil supplements are the most effective source. Speak to your vet about appropriate dosage for your dog's weight.

Environmental Management

At home:

Wash your dog's bedding weekly in hot water (above 60°C)
Vacuum carpets and upholstery regularly -pollen settles into soft furnishings
Use an air purifier with a HEPA filter in rooms where your dog spends most time
Keep windows closed on high pollen days
Wipe your own clothes and hands before touching your dog on high pollen days

In the garden:

Avoid walking your dog on freshly mown grass
If you have a garden, mow lawn regularly before pollen heads develop
Avoid planting allergenic trees close to your dog's favourite outdoor area

Medication and Treatment Options

For dogs with significant spring allergies, medication is often necessary:

Apoquel (oclacitinib): A daily tablet that blocks the itch signal. Fast-acting, effective, and suitable for long-term use. Available by prescription only. Cytopoint (lokivetmab): A monoclonal antibody injection given monthly. Targets and neutralises the key itch-causing protein (interleukin-31). Particularly useful for dogs who resist oral medication. Antihistamines: Less effective in dogs than in humans, but worth trying under vet guidance. Some dogs respond well; most respond partially. Common options include cetirizine and chlorpheniramine. Steroids (corticosteroids): Powerful anti-inflammatories used short-term for severe flare-ups. Effective but carry significant side effects with long-term use. Not recommended for ongoing spring allergy management. Immunotherapy: The only long-term cure for environmental allergies. Involves a series of allergy shots or drops containing small amounts of your dog's specific allergens. Takes 6-12 months to take full effect but can provide lasting relief for many dogs.

UK Spring Pollen Calendar for Dog Owners

Understanding the UK pollen calendar helps you anticipate when your dog's symptoms are most likely to flare:

Month	Primary Pollen	Peak Risk
January	Hazel, alder	Low -but dogs sensitised in previous year may start early
February	Hazel, willow	Low-Moderate
March	Hazel, elm, birch	Moderate -start of peak season
April	Birch, oak, ash	High
May	Grass begins, tree pollen continues	Very High
June	Grass peak, weed pollen begins	Peak season
July	Grass peak	Peak season
August	Grass declines, weed peak	Moderate-High

FAQ

Can dogs get hay fever like humans?

Yes, but they show it differently. Humans get runny noses and itchy eyes. Dogs get itchy skin, especially paws, ears, and face. If your dog is excessively scratching in spring and summer, suspect seasonal allergies rather than a cold.

Are some breeds more prone to spring allergies?

Yes. Breeds predisposed to atopic dermatitis include: Labrador Retrievers, Golden Retrievers, French Bulldogs, West Highland White Terriers, Jack Russell Terriers, Dalmatians, Boxers, and German Shepherds. If you have one of these breeds, start your spring allergy management early.

Can I give my dog human antihistamines?

Some human antihistamines are used in dogs under veterinary supervision, but dosing is weight-dependent and some human formulations contain decongestants that are toxic to dogs. Always consult your vet before giving any human medication to your dog.

Does diet affect spring allergies?

Diet doesn't directly cause environmental allergies, but nutrition significantly affects skin barrier function. Dogs with seasonal allergies benefit from:

High-quality protein sources
Omega-3 supplements (fish oil)
Foods containing prebiotics for gut health
Avoiding ingredients your dog has a confirmed food sensitivity to

Is there anything I can do before spring starts?

Yes -this is called proactive management. Starting allergy medication 2-4 weeks before your region's pollen season begins is far more effective than treating symptoms after they appear. If your dog had spring allergies last year, book a vet appointment in February to set up a management plan for this year.
