well i will be a dissenter (wow, funny that!).
in addition to raw bones, bully sticks, moo tubes and all natural pig ears, my dog does get all natural compressed rawhides - he loves to gnaw on them and they take longer to eat than anything else (this dog can finish off a RMB or recreational bone in about 20 minutes!), so he has them when supervised, and i take them away once they get below 4-5 inches. they are the only thing he CANNOT break big pieces off of.
