Hi,
I have given my pups meaty pork neck bones and ground pork with no ill effects. But my main source of raw meaty bones is chicken backs. You can also use wings, beef necks, knuckles, etc. As long as it's not cooked it's ok for dogs. Depending on your dog's jaw the bigger bones might be a challenge but you dont want the pieces too small, in case they gulp them down. My only reservation on feeding bones is the weight bearing legs from chicken and turkeys-- I grind these (bones and all) and mix with veggie pulp on occasion. My other problem with these bones is there's not enough bone in something like a chicken leg quarter to provide for balanced calcium. So when I use this I also sprinkle on some crushed egg shells to add more calcium.
I have heard that some dogs can get the runs from beef. And there can be a possibility of parasites from pork. My pups have been eating this way since January and they're doing fine. Watch you dog and see. You are the best judge of how he is doing.
