I have never given my dogs Bully sticks but I do know about pig ears. They are not bad, but if chewed too quickly, the dog can choke on them easily. Rawhides are not good for dogs, if left or barried they can get soggy and moldy, hurting the dog if it is later eaten, it is not healthy either, no matter how much the pet store or advertiser claims it is it is not so please do not buy rawhides... any kind!
