@Patty:
Mine are rarely given bones and I'm sceptical about chicken wings as if they're from free range chicken they can splinter. Chickens reared in crates or enclosed spaces are sold for meat at a very early age when the bones are still relatively soft. These should be ok. Mine only have artificial or sterilized bones. They love Nylabones which do seem to be good for the teeth.
As someone who feeds raw, and sees fine powder poo, trust me dogs digest the raw just fine. In fact I don't give sterilized bones as so hard they can crack their teeth and I have had some very aggressive chewers. Take a flashlight and check your dog's teeth occasionally and remove hard bones if you start seeing crack lines.
Dogs eat and process far harder bones than chicken… pork neck and others... Do what you feel comfortable with, but please be aware there are now masses of raw meaty bone feeders and the dogs are healthy and fine.
