One of my daughters used to raise Chows. One of them scratched herself bloody in one spot, so on the advice of friends she rubbed Avon's Skin so Soft on it. Hair came in so soft and lovely DD had the dog stripped and rubbed her all over with Skin so soft often.
One of my cats was scratching a lot so I rubbed some coconut oil on her fur and rubbed it in to the skin. That helped a lot. I also use it on my own hair.
