A sled dog's coat on a weekly schedule
The Chinook, the rare sled breed from New Hampshire, carries a thick double coat in tawny shades, with a soft dense undercoat, a coarser outer layer, and longer hair at the neck, shoulders, and tail. Weekly grooming with an undercoat rake and a slicker, worked in sections to the skin, keeps that undercoat breathing and removes dead hair before it packs. The breed sheds lightly to moderately between blows, so the weekly session is more inspection than battle: it is also the moment to feel for lumps under all that coat, check the feathering behind the legs for tangles, and confirm the skin is clean and calm.
The blow: when weekly becomes daily
Once or twice a year a Chinook sheds its undercoat in earnest, and the grooming schedule has to change with it. During a blow, brief daily brushing removes far more hair, far more kindly, than a single exhausting weekly session, and it prevents the loosened undercoat from felting into the guard hairs around the neck and britches. A bath partway through, followed by truly complete drying, which takes patience in this coat, helps the remaining dead hair release. Expect hair on everything for a few weeks regardless; daily sessions reduce the chaos and keep the dog comfortable while the new undercoat grows in.
Rules for a northern double coat
A Chinook's coat should not be clipped or shaved: the double layer insulates against cold and, less obviously, against heat and sun, and regrowth can return patchy with the texture changed. Bathing should be infrequent, since the coat carries little odor and the skin under a dense undercoat dries slowly and irritates if washed often; when a bath happens, rinse longer than seems necessary and dry to the skin. Snow and ice ball up in the longer hair between the toes in winter work, so feet deserve a check after snowy outings, and nails should be looked at every couple of weeks year-round. Ears, being upright and open, need only a regular glance.
A Chinook routine through the working year
A Chinook kept as a working or hiking dog adds a few seasonal notes to the weekly brush. In winter, check the longer hair between the toes after snowy outings, because ice balls form there and change the dog's gait on a long run; in summer, the same weekly session should include a tick check, since the dense coat around the neck hides them well. Condition matters in a breed built to pull: run your hands over the ribs under all that coat whenever you brush, because a Chinook's weight is easy to misjudge by eye. The coat will tell you the seasons before the calendar does.
Coat changes worth a vet conversation
A Chinook losing hair in patches outside the normal blow, developing bald spots that do not regrow, or scratching constantly under the coat should be seen by a vet, because that dense undercoat hides skin disease until it is well established. A sudden change in coat texture, heavy dandruff throughout, or lumps felt during the weekly brush also belong on the appointment list. Older Chinooks that resist grooming around the hips or shoulders may be sore rather than stubborn. Logging the weekly brush-outs and the daily blow-season sessions in KinsLe Care Teams keeps your Chinook's coat care consistent across the household.
