Our Labrador will swallow a rabbit rib cage the size of a small grapefruit in one piece. Would like to feed him the rest of the carcass, but worry he'll swallow leg bones in one piece too. I don't think he'll choke, he can eat pretty big bits of meat, but I do worry about how well a leg bone will make it through the other end! Is there a safe way to introduce them? Once given, it'll be impossible to get the meat back off him!
