Spring Allergies in Dogs and Cats: What to Watch For

Pets experience seasonal allergies differently than most people expect, since the human-typical sneezing and watery eyes pattern is actually less common in dogs and cats — the more frequent presentation is skin-related, which catches a lot of owners off guard when they're looking for a "sneezing" pattern that doesn't quite match what's actually happening.

Itchy, inflamed skin is the most common allergy symptom in dogs and cats, often concentrated on the paws (excessive licking or chewing), ears, belly, and face — a pet who's suddenly much more itchy starting in spring, without a clear cause like fleas, points toward environmental allergies as a likely culprit.

Secondary skin infections often follow the initial allergic itching — the scratching and licking response to allergy-related itch can break the skin's protective barrier, allowing bacterial or yeast overgrowth that compounds the original problem, sometimes requiring its own separate treatment beyond just managing the allergy itself.

Ear infections increase in frequency during allergy season for many dogs, since the same inflammatory response affecting skin elsewhere on the body often affects the ear canal too — recurring ear infections that seem to follow a seasonal pattern are worth investigating as a potential allergy sign.

True respiratory allergy symptoms do occur but less commonly than the skin presentation — occasional sneezing, watery eyes, or mild coughing tied to spring pollen can happen, just less frequently as the primary symptom compared to skin-related signs.

What to do: If you notice increased itching, paw licking, or ear issues starting with a seasonal pattern (worse in spring, improving in other seasons), discuss allergy management with your vet — options range from managing symptoms during flare-ups to more comprehensive allergy testing and long-term management for pets with significant, recurring seasonal symptoms.
