Spring flowers and sunny weather may feel refreshing to people, but for some pets, seasonal changes bring nonstop itching, licking, and scratching instead. At Olympia Veterinary Hospital, your Tumwater, WA veterinary clinic, seasonal allergy flare-ups are one of the most common reasons dogs and cats visit us during warmer months. Pets with allergies often become uncomfortable long before owners realize what is happening, especially when symptoms begin gradually.

Seasonal allergies don’t just make pets a little itchy—they can bother your pet’s skin, ears, paws, and even their mood. While we humans might reach for the tissues when allergies hit, our pets usually show their discomfort by scratching, licking, or developing irritated skin. Knowing what to watch for and how to help can make allergy season a lot more bearable for your four-legged family member.

What Causes Seasonal Pet Allergies?

Seasonal pet allergies pop up when your pet’s immune system decides to treat harmless things like pollen or dust as if they’re public enemy number one.

Common seasonal triggers include:

• Grass pollen
• Tree pollen
• Weed pollen
• Mold spores
• Dust
• Outdoor plants

When pets come into contact with allergens, the immune system may respond with inflammation and irritation. That inflammation often affects the skin first, especially in dogs.

If you live in a place where the seasons like to keep you guessing, your pet might have allergy flare-ups in spring, summer, or fall—depending on which allergens are making their grand entrance.

Why Pets Show Allergies Through Their Skin

While we humans tend to sneeze and sniffle our way through allergy season, our pets usually show their allergies on their skin and in their ears.

Seasonal allergies in dogs commonly cause:

• Itching
• Paw licking
• Ear infections
• Red skin
• Hair loss
• Hot spots

Kitties, on the other paw, might start over-grooming, develop scabby spots, or end up with irritated skin.

If your furry pal is scratching up a storm, it’s not just because they’re bored—those allergies can make them downright miserable.

Some pups get so determined with their scratching, you’d think they were trying out for a spot in a rock band—right on your living room rug.

Seasonal Allergies in Dogs

Seasonal allergies in dogs are especially common and may worsen during warmer months when pollen levels rise.

Dogs with allergies often develop irritation around:

• Paws
• Ears
• Belly
• Armpits
• Face

You might catch your dog chewing on their feet after a stroll outside or giving your couch a good face rub—classic allergy moves.

Some dogs also develop recurrent ear infections linked to allergies because inflammation affects the ears as well as the skin.

The bad news? If allergies are left unchecked, those symptoms usually get worse over time.

Cat Allergy Symptoms Can Look Different

Cats like to keep us guessing, including how they show allergy symptoms. Sometimes it’s tricky to spot the signs at first.

Common cat allergy symptoms include:

• Excessive grooming
• Bald patches
• Scabs around the neck or head
• Ear irritation
• Itching
• Sneezing

Some cats are so sneaky with their overgrooming that you never catch them in the act—you just find mysterious bald patches popping up like magic.

Your feline overlord might also get a bit cranky or decide to hide out more than usual if allergies are making them uncomfortable.

Why Pets Become Itchy During Spring

Springtime means pollen is in the air—and that means lots of itchy pets coming through our doors.

Allergens may cling to:

• Fur
• Paws
• Bedding
• Furniture
• Carpets

After outdoor exposure, allergens remain on the skin and coat, continuing to trigger irritation even after your pet comes back inside.

Some dogs seem fine indoors but begin scratching intensely after walks, hikes, or playtime outside.

Paw Licking and Chewing

One of the most noticeable signs of seasonal pet allergies is excessive paw licking.

Pets often lick or chew paws because allergens collect between the toes and around paw pads after outdoor exposure.

Signs of irritated paws may include:

• Red skin
• Brown saliva staining
• Swelling
• Constant licking
• Limping

Some dogs become so focused on paw licking that owners initially mistake it for a behavioral habit instead of an allergy problem.

Ear Infections and Allergies

Recurring ear infections are frequently linked to allergies, especially in dogs.

Allergic inflammation can create warm, moist conditions inside the ears, which may allow yeast or bacteria to overgrow.

Signs of ear problems include:

• Head shaking
• Ear scratching
• Redness
• Odor
• Discharge

Pets with chronic ear issues often need both allergy management and treatment for active infections.

Hot Spots and Skin Irritation

Hot spots are inflamed areas of skin that may develop quickly after scratching, licking, or chewing.

These painful skin lesions may appear:

• Red
• Moist
• Swollen
• Tender

Dogs with thick coats are especially prone to hot spots during warm weather.

Because hot spots can worsen rapidly, veterinary treatment is often needed to reduce discomfort and prevent infection.

Can Seasonal Allergies Affect Behavior?

Absolutely. Pets dealing with chronic itching and irritation often become restless, frustrated, or less playful.

Behavior changes may include:

• Trouble sleeping
• Irritability
• Increased clinginess
• Restlessness
• Hiding behavior in cats

Your furry friend may not understand why they feel uncomfortable, which can affect mood and daily routines.

Some pets lose interest in normal activities because constant itching is exhausting.

Allergy Treatment for Pets

Allergy treatment for pets depends on symptom severity, lifestyle, and the underlying triggers involved.

Your veterinarian may recommend:

• Prescription medications
• Flea prevention
• Medicated shampoos
• Ear treatments
• Dietary changes
• Skin support therapies

There is rarely a quick fix for allergies. Treatment usually focuses on managing inflammation and reducing discomfort long-term.

The goal is to help your furry pal enjoy a better quality of life while minimizing flare-ups.

Bathing and Grooming Can Help

Regular grooming may help reduce the amount of allergens trapped in the coat and on the skin.

Helpful grooming strategies include:

• Wiping paws after walks
• Regular brushing
• Veterinary-approved shampoos
• Keeping bedding clean

Bathing pets too often without veterinary guidance can dry the skin and worsen irritation, so balance matters.

Cats generally have strong opinions about baths, most of them negative.

Flea Prevention Still Matters

Even if seasonal allergies are triggered primarily by pollen or environmental allergens, flea prevention remains important.

Flea bites can dramatically worsen itching in allergic pets. Some animals are so sensitive that even a single flea bite can trigger severe irritation.

Year-round parasite prevention often plays an important role in allergy management plans.

Why Veterinary Diagnosis Matters

Many skin conditions look similar on the surface. Allergies, infections, parasites, and hormonal disorders may all cause itching and skin irritation.

Your veterinarian may recommend:

• Skin exams
• Ear evaluations
• Allergy discussions
• Diagnostic testing
• Cytology or skin sampling

Accurate diagnosis helps your veterinary team create the most effective treatment plan for your pet’s specific needs.

Supporting Pets During Allergy Season

While allergies cannot always be prevented completely, some habits may help reduce flare-ups.

Helpful tips include:

• Keeping pets clean after outdoor time
• Washing bedding regularly
• Using consistent flea prevention
• Monitoring symptoms early
• Scheduling routine veterinary visits

Early treatment often helps reduce more severe skin irritation and secondary infections later.
