My golden is a very itchy/sensitive dog. After trying a million foods, Purina Sensitive Skin and Stomach is the food I have found works the best for him. His itching is hardly there (I think his issues are chicken and potatoes)--and his hot spot issues have decreased tremendously....occasionally he'll still get a tiny one--but I've tried some foods that have given him serious hot spots in a matter of two days (one cup of new food being added in). I will say I'm not 100% thrilled with his coat on this food compared to some others--but I'm picking and choosing my battle there. I also continue to look because I don't feel his energy level on the PP is as good as it is on other foods. But he is 10 now....so maybe he's just settled....I don't know. His coat is not horrible by all means--and my lab also eats this and her coat is fantastic. But I think she got good coat genes, too.

Good luck!
Oh and NO gas for either dog on this either.
Edited to also add--I did try Acana Pacifica for him--and he did well on it. I only fed 3 small bags of it and getting it from the store became impossible and then they closed (or so I thought--but found out today, they reopened under a new name/place). But he is not carrying the Acana now. I'd definitely try it again if I could get it with ease.
