You know, asking about food for your dog on a forum is not a smart idea. You should visit a special site at least. Personally, I read this website when I needed to help my dog to overcome years infection. Visiting a vet was really expensive and I decided that the internet is able to give me all the necessary information
We've tried foods such as solid gold, and wellness and also find that not only is it very expensive, it still leaves their coats very dry. Raw meats are very high in protien, and the natural oils in the raw meats are put to very good use with the dogs as far as their skin and coats. You can also feed them raw veggies, but we've found that our blue nosed pits do fine on just raw meat alone, just no pork. Beef chicken liver etc. The first week introduce your dog to raw foods in portion. After the raw foods kick in you will notice a completely different dog.
