Short answer: Double-coated dogs — Huskies, German Shepherds, Golden Retrievers, Bernese, and their mixes — "blow their coat" twice a year, and the spring blow-out hits hard as New England warms up. The undercoat releases in clumps over roughly two to four weeks. The fix is frequent de-shedding, never shaving, and — for heavy coats — a professional de-shed with a high-velocity dryer that pulls out loose undercoat a home brush can't reach.
Every March and April, whether you're in a Seaport condo or a Lynnfield colonial, the same thing happens: the tumbleweeds arrive. If you own a double-coated dog, the New England spring shed is a rite of passage — and one of the most-Googled dog questions this time of year.
What "blowing coat" actually is
Double-coated breeds have two layers: a coarse outer guard coat and a dense, soft undercoat that insulates. As daylight lengthens and temperatures climb, the dog sheds that winter undercoat in bulk to prep for summer. This isn't the light, year-round shedding of a Lab — it's the undercoat releasing in handfuls, especially around the neck, hips, chest, and tail, over a two-to-four-week stretch. It happens again in fall to grow the winter coat back.
The number-one rule: never shave a double coat
It's tempting to think shaving a Husky in July keeps it cool. It does the opposite. The double coat regulates temperature in both directions and shields skin from sunburn; shave it and you damage the coat's ability to insulate and protect — sometimes permanently — and it can grow back patchy or coarse. Manage the undercoat instead. Don't remove the whole system.
Managing the shed at home
During a coat blow, daily brushing is both realistic and helpful. The right tools matter more than raw effort: an undercoat rake to reach the dense underlayer, a slicker brush to lift loose hair and distribute skin oils, and a metal comb to catch what's left and find early mats.
Work through the coat in sections, and don't overdo de-shedding tools on the guard coat — aggressive use can damage it. A bath before a big brush-out actually loosens undercoat and speeds things along, as long as you dry thoroughly; trapped moisture against the skin of a thick-coated dog invites hot spots.
When to call in a professional de-shed
There's a point where a home brush simply can't keep up — and that's where a professional de-shedding appointment changes everything. A groomer's high-velocity dryer physically blows loose undercoat out of the coat down to the skin, removing volumes of fur no handheld tool matches, followed by a thorough rake and comb-out. For a Husky or Shepherd mid-blow, one good professional de-shed can spare you weeks of vacuuming and keep the coat healthy. It's also the appointment where we catch skin issues, early mats behind the ears and in the "armpits," and — critically on the North Shore in spring — ticks hiding against the skin.
Add a de-shed to a daycare or boarding day and your dog comes home clean, comfortable, and dramatically less fluffy, without you spending the weekend with a rake.
Health notes
Sudden, patchy, or year-round excessive shedding beyond the normal seasonal blow can signal diet gaps, parasites, or skin issues — worth a vet conversation. Good nutrition (adequate omega fatty acids, and zinc for northern breeds) supports coat health. And keep fresh water available; a shedding, warming dog needs it.
FAQ
Why is my dog shedding so much in spring? Double-coated breeds blow their winter undercoat as it warms — a normal 2–4 week process.
Should I shave my Husky in summer? No — shaving a double coat harms insulation and sun protection and can damage regrowth.
Is a professional de-shed worth it? For heavy double coats, yes — a high-velocity dryer removes far more undercoat than home brushing.
