How long have you been giving them consistently? It may take until his next shed to see a difference. When it comes to dry skin, you see a difference pretty quickly, but if it is a coat quality issue, you have to have them on it for a while before they shed and then wait until after the shed. Neutering does affect coat and it really affects coat on breeds like the Golden. I’ve known many Goldens with the nickname Fluffbuff.
