Tripe mince and whitetail.
When I was growing up, my grandmother bred German Shepherd's , all of which were fed a raw diet because my Grandfather was a butcher. The difference between the health of her dogs and the dogs of other breeders was massive, she made a lot more for her pups just because her dogs just always looked so healthy. I'm from Ireland and dogs eating a raw diet is really rare but it's really beneficial. I personally don't believe people should have dogs if they're not fed a raw diet.
