If Alaska's coat is not shiny, you need to supplement your dog's nutrition. Let the dog eat more food rich in protein, vitamins, and trace elements. You can also give the dog lecithin, so that the dog's hair will also become shiny. Moreover, you should comb your dog's hair every day to promote blood circulation. When bathing, you should use dog-specific shower gel. Do not use human shower gel, otherwise it will damage the dog's hair and skin.
