Spring Allergies in Dogs & Cats Explained

As the weather becomes milder and plants begin to bloom, many pets start spending more time outdoors. For some dogs and cats, however, spring can also bring itchy skin, irritated paws, watery eyes and other uncomfortable symptoms linked to seasonal allergies.

If your pet seems more uncomfortable during the spring months, allergies may be one possible cause. Understanding what to look for, what may be triggering the problem, and when to seek veterinary help can make a real difference to your pet’s comfort.

This article is intended for general guidance only and should not replace professional veterinary advice. If your pet is unwell or showing concerning symptoms, please contact your veterinary surgeon.

What are spring allergies in pets?

Spring allergies happen when a pet’s immune system overreacts to something in the environment. In spring, common triggers include pollen from trees, grasses and weeds, as well as mould spores and other airborne particles.

In people, allergies often cause sneezing and runny noses. In pets, especially dogs, allergies more commonly affect the skin. Cats can also develop skin irritation, but some may show respiratory signs such as sneezing or watery eyes as well.

Seasonal allergies are sometimes called “atopy” or “atopic dermatitis” when they affect the skin. This simply means an allergy-related skin condition triggered by environmental allergens.

Which pets are most affected?

Both dogs and cats can suffer from seasonal allergies, although dogs are more commonly affected. Some pets are also more prone than others.

Dogs

Dogs with environmental allergies often begin showing signs from a young adult age, although symptoms can develop earlier or later. Certain breeds may be more likely to develop allergic skin disease, including:

• West Highland White Terriers
• Labrador Retrievers
• Golden Retrievers
• Boxers
• French Bulldogs
• Staffordshire Bull Terriers

Cats

Cats can also develop allergies to pollen and other seasonal triggers. In cats, allergy signs can sometimes be mistaken for overgrooming, stress-related grooming, or flea problems, so veterinary assessment is important.

Common spring allergy symptoms in dogs and cats

The signs of seasonal allergies can vary from pet to pet. Some have mild itching for a few weeks, while others become very uncomfortable and may need prescription treatment to control their symptoms.

Common signs in dogs

• Itching, scratching or rubbing
• Licking or chewing the paws
• Red, inflamed skin
• Ear irritation or recurrent ear infections
• Rubbing the face or muzzle
• Hair loss caused by licking or scratching
• Watery eyes
• Skin infections developing alongside the allergy

If your dog struggles with itchy skin during spring, it may be helpful to explore our dog allergy products and dog skin and coat products once you have spoken with your veterinary surgeon.

Common signs in cats

• Overgrooming or excessive licking
• Itchy skin or scabs, especially around the head and neck
• Hair thinning or bald patches
• Sneezing
• Watery or irritated eyes
• Ear irritation
• Skin redness or discomfort

For cats with skin-related concerns, our cat allergy products and cat skin and coat products may be relevant, depending on your vet’s advice.

What causes spring allergies?

Pets with seasonal allergies usually react to allergens in their environment rather than to something they have eaten. During spring, common triggers include:

• Tree pollen
• Grass pollen
• Weed pollen
• Mould spores
• Dust and outdoor particles stirred up in dry weather

When these allergens come into contact with the skin, paws, ears or airways, they can trigger inflammation. This often leads to itching, redness and discomfort.

It is also worth remembering that flea allergy can flare up at the same time of year. Even one flea bite can cause intense irritation in sensitive pets, so it is important not to assume the problem is only caused by pollen. Keeping up to date with flea, tick and worming treatments is an important part of ruling out other common causes of itching.

How are seasonal allergies diagnosed?

There is no single at-home test that can reliably confirm spring allergies in pets. Your veterinary surgeon will usually diagnose the condition by looking at your pet’s symptoms, when they occur, and whether other common causes of itching have been ruled out.

Your vet may consider:

• Fleas or flea allergy
• Food allergy
• Mites or other parasites
• Skin infections
• Ear disease
• Other underlying health conditions

In some cases, your vet may suggest further tests or refer your pet for allergy testing, particularly if symptoms are severe or ongoing.

Treatment options for spring allergies

Treatment depends on the severity of the allergy, the type of symptoms your pet is showing, and whether there are any secondary problems such as skin or ear infections.

1. Avoiding or reducing exposure

It is not usually possible to avoid pollen completely, but small changes can help reduce your pet’s exposure:

• Wipe your pet’s paws and coat after walks or time outdoors
• Wash bedding regularly
• Vacuum more often during high pollen periods
• Keep grass short in the garden where practical
• Try walking dogs early or later in the day if pollen counts are particularly high

2. Medicated washes and skin support

Some pets benefit from gentle shampoos, mousse products or topical skin support recommended by a vet. These may help remove allergens from the coat and soothe irritated skin.

You can also browse our dog supplements, cat supplements and premium supplements if your veterinary surgeon recommends nutritional support as part of a wider skin-care plan.

3. Prescription allergy medication

Some pets need prescription-only medication to control itching and inflammation. This may include tablets, liquids, spot-on treatments or injections, depending on the pet and the condition being treated.

Prescription treatment should only be used under veterinary guidance. If your pet has already been prescribed medication, you can find out more about how to order a prescription medicine, browse prescription medicines, or read our prescription FAQs.

4. Treating ear or skin infections

Allergic pets are more prone to secondary infections. If your pet has sore ears, a bad smell from the skin, sticky discharge, or worsening redness, your vet may need to prescribe treatment for the infection as well as the allergy itself.

Supportive products for ongoing care may sometimes be useful alongside veterinary treatment, such as dog ear products, cat ear products, dog eye products or cat eye products, depending on your pet’s needs.

When should you contact your veterinary surgeon?

It is always sensible to speak to your vet if your pet has ongoing itching or recurring skin problems, especially if symptoms are new or getting worse.

You should contact your veterinary surgeon promptly if your pet:

• Is scratching constantly or seems very uncomfortable
• Has broken skin, bleeding, swelling or sores
• Has a bad smell from the skin or ears
• Develops hair loss or bald patches
• Has red, sore or discharge-filled eyes
• Is shaking their head or appears to have painful ears
• Has difficulty breathing or severe sneezing
• Seems unwell in themselves, quiet or off their food

These signs may suggest infection, significant inflammation, or another problem that needs proper diagnosis and treatment.

Can spring allergies be prevented?

Seasonal allergies cannot always be prevented, especially in pets that are naturally prone to them. However, careful management can reduce flare-ups and help keep your pet more comfortable.

• Keep flea prevention up to date
• Monitor for early signs of itching each spring
• Book a vet check if symptoms return each year
• Follow treatment plans exactly as prescribed
• Use pet products responsibly and only as directed

If your dog or cat has a history of seasonal skin trouble, it can help to prepare early by checking your supplies and discussing a plan with your vet before symptoms become severe.

Helping your pet stay comfortable this spring

Spring allergies can be frustrating for both pets and owners, but with the right support, many dogs and cats can be kept comfortable throughout the season. Early symptom awareness, good parasite prevention, and prompt veterinary advice are often the best ways to stop mild irritation turning into a more serious skin problem.
