Flea allergy
In a pet allergic to fleas, a single bite can drive days of intense itching, so "I've never seen a flea on him" doesn't rule it out. For pets with other allergies, their skin is so sensitive that they react more to a flea bite than they would otherwise. Our mild, damp climate keeps fleas around all year, which makes year-round prevention a key part of allergy symptom control.
