Only give him raw bones and only the ones that are too large for him to swallow whole. I give my dogs their raw meat and bones, that they are going to chew up and swallow outside. The bones that they are just going to chew on for recreation, they get in the house. I have been giving my dogs raw bones as long as I have had dogs, 20 years or more, and I have never had a problem. I wouldn't particularly want chicken bones all over my house, but I don't worry about beef or pork. Ribs are great to give your dogs, because the bones are soft enough that they actually eat the whole thing, not just chew on it, if they are big enough to chew it up.
