The raw meat you are feeding has good protein, so gain 20% is what i would feed, its up to you but feeding 28% on top of Beef, Rabbit and fish is a lot of protein.I've often wondered about that Joe and I understand what you're saying but with Gain 28 and Redmills Racer being cheap dog foods, surely the quality of protein in them is poor ie sourced from veg etc??? I use the complete as a mixer and they don't get a lot...a max of 30% of their food :-)
