All dogs LOVE rawhides, however, they are not good for them. I would not give your dog anymore, even though he does like them. These can get caught in their throats and choke to death and can cause diahhrea etc....
The best bone you can get for your dog is a raw marrow bone from your butcher. Search the archives in this forum, there is lots of good advice about chew toys and food.
