Alaskans have less hair and need to supplement their nutrition. Let them eat more egg yolks, chicken breasts, lecithin, etc., especially during the moulting period, so that the new hair will grow longer. Okay, but you also need to comb your dog's hair every day to prevent the hair from getting tangled. When bathing your dog, use dog-specific shower gel instead of human shower gel to avoid irritating the skin.
