As Spring Blooms, So Do Allergies: Pets Face Seasonal Pollen Surge

Urban veterinarians report rising allergy symptoms in dogs and cats as pollen and pollution collide

Tokyo — A Season of Beauty, and of Itch

As Tokyo’s parks come alive with cherry blossoms, another annual arrival stirs quietly beneath the surface: a surge in pet allergies. While humans reach for tissues and antihistamines, their furry companions may also be suffering — often in silence.

Veterinarians across the capital are seeing an uptick in dogs and cats exhibiting symptoms commonly associated with seasonal allergic rhinitis, or hay fever. In dense urban environments, where pollen mingles with air pollutants, the effects can be particularly pronounced.

Scratching, Sneezing, and Something More

“It’s not just a few sneezes,” says Dr. Ayaka Fujimoto, a veterinarian in Shibuya. “We’re talking about persistent skin irritation, red eyes, inflamed paws, and even respiratory issues.”

Among the most commonly reported behaviors: excessive licking or scratching, frequent sneezing, watery or red eyes, and patchy fur loss. While some pet owners might dismiss these as harmless quirks, experts warn that they may signal more serious allergic reactions to tree, grass, or weed pollen.

City Living: A Hidden Catalyst

In high-rise apartments and along car-clogged streets, pets are particularly vulnerable. Unlike their rural counterparts, urban pets are exposed not only to natural allergens, but also to particulates from vehicle emissions and construction dust — all of which can worsen allergic responses.

Even the simple act of walking outside can turn hazardous during peak pollen season. Vets recommend brushing or wiping your pet’s fur and paws immediately after returning home — especially before entering shared spaces like elevators.

Combatting Pollen, One Routine at a Time

Reducing exposure is the first line of defense. Pet owners are encouraged to adopt habits that minimize pollen contamination indoors. These include:

• Brushing and wiping down pets after every outdoor excursion

• Using air purifiers with HEPA filters in common areas

• Vacuuming and cleaning soft surfaces like carpets and curtains regularly

• Replacing air conditioning filters more frequently during spring and summer months

These small changes, experts say, can significantly reduce airborne allergens in the home.

Early Intervention Is Key

Should symptoms persist, professionals stress the importance of early veterinary consultation. “We have access to allergy testing and can tailor treatment plans based on the pet’s individual sensitivity.

Treatment may include antihistamines, topical creams, dietary changes, or even immunotherapy — all aimed at relieving the pet’s discomfort and improving their quality of life.

A Season to Enjoy — For All Species

While spring remains a beloved time for humans and animals alike, it also presents challenges for sensitive pets. With a watchful eye, a clean home, and guidance from veterinary professionals, pet owners can ensure their companions thrive during even the sneeziest of seasons.
