We became totally disillusioned with complete dog food and now cook for our adult dogs. We give some raw but on the whole most is cooked. Lots of veg, people graded meat, poultry etc, we add bran. Eggs, yogurt + cheese make up the protein. Dogs are much happier, healthy and never leave a crumb. It might be more work, but well worth the effort. It is an alternative to feeding totally raw.
