I have a 12 week old pb staffy and i have been giving him bones ever day since he was 6 weeks old. i give him chicken necks, carcasees, wings, lamb bones etc etc etc. I always give them raw never ever cooked. I have never had a problem with him. I agree with zee8477 as a dog digestive system can process them no problems. Have you tried a chicken carcase so the dogs have to chew them up without swallowing chunks???
