The yellow hair on the back of Alaska's front legs may be caused by improper care or malnutrition. The dog needs to be cleaned carefully. If it cannot be cleaned, the yellow hair can be cut off. At the same time, the dog needs to be supplemented with nutrition. Groom the dog's hair more often to promote blood circulation, take the dog to bask in the sun every day, bathe the dog regularly and deworm the dog. If you persist for a period of time, the color of the new hair will turn white.
