If the Alaskan coat is knotted, you can use a comb to comb the knotted hair, or you can shave the dog's hair shorter to make it easier to comb. It is best to bathe the dog twice a month. When using dog shampoo and conditioner, the hair will be smoother. You should also supplement your dog's nutrition at ordinary times, and let your dog eat more egg yolks, chicken breasts, lecithin and other foods.
