I'm pretty confused. Do dogs eat the bone or not? A friend of mine got a few deer rib bones for me and they're freezing for a couple of days before I give them to my dog. I askled for ribs because of the knuckle/femur bone thing, if I shouldn't give rib bones what kind of bones should I get? I've heard that chewing on the bones is good for their teeth and helps with doggy breath and that's my main motivation for giving him the bones.
