I have a husky who malts too. During winter months, the dogs coat becomes fuller and can get quite matted. I would assume it is natural, as these dogs are bred for life in arctic conditions (snow, cold etc,...) they will easily adapt to cold, winter conditions by producing a thicker coat to keep them warm. Its quite simply a matter of getting out your grooming brush at the beginning of summer, and brushing out the "thick bits" (mine are usually around the leg and chest areas), until the excess hair is removed! (Just be glad they don't 'actually' malt like some other breeds who lose hair continuously on your furniture!!!)
