What is the name of the seasonal shedding period common in double-coated breeds?

The story behind the answer

Blowing coat is the common term for the dramatic, seasonal shedding in double-coated breeds (e.g., Huskies, German Shepherds). During this period, they shed large amounts of undercoat to adjust insulation as daylight and temperatures change. Unlike “seasonal molt” (a term more typical for birds) or “winter blowout” (too season-specific), “blowing coat” accurately describes the big release of underfur that can occur in spring and sometimes fall.

Why it happens: the dense undercoat keeps dogs warm; when seasons shift, hormones triggered by changing daylight prompt the coat to loosen. Memory tip: think of a fan “blowing” tufts of fur like snow. Grooming help: frequent brushing with an undercoat rake and a bath can speed the shed; avoid shaving double-coated dogs, as it can damage coat function and make temperature regulation harder.
