Some of my dogs are chewers, some aren't. Some will chew for a long time, some just for a few minutes. I ONLY give them hooves and antlers. Rawhide makes me nervous as I have heard horror stories of the problems they can cause. Same with bully sticks which are basically rawhide.
Several of my dogs have never had anything BUT antlers and hooves. We call them "bones" and who are they to know the difference.
