Ive been wanting to feed my guys raw bones for awhile now, mostly for the teeth cleaning benefits and as a treat. Ive been mostly looking into turkey and or duck necks but I can never find them. When I looked at the grocery store they had beef marrow bones and suet, pig hocks, the usual bone in chicken pieces, and chicken livers. I didn't see any either when I want to the more organically based grocery store. And I can only find marrow bones at the petstores. Where do you normally find things like turkey/duck necks? What are other raw bones that are good for helping keep their teeth clean?
