I think it depends alot on what suits the dog - the dog is bound to have the final say! I don't know much about raw feeding that lots of people have mentioned, but I know the nutrient levels and calorific values would have to be thought out to ensure a balanced diet is given. I would worry about bones and how they could cause injury and what comes out the other end too!! My two are quite happy on their complete Arden Grange anyway.
