The moulting period for adult Alaskan dogs generally lasts about 3 months. There are two moulting periods every year, from March to May in spring and from September to November in autumn; Alaskan puppies are about three months old. Moulting begins, and the moulting period will last for about 3 to 6 months, until all the lanugo hair has been replaced at 8 to 11 months. When your dog is moulting, it is best to pay more attention to diet and hygiene so that the hair will be healthier.
