I have limited rawhide experience since our vet warned us about issues with them (choking, impactions, disease if not from US,etc). Our lab had one or two as a special treat and highly supervised. It never upset his stomach, although he had a cast iron stomach.
Riley gets a 12 in bully stick about every week. It usually takes him that long to finish one. I take the old one away when it is about 2in and give him the new one. He's not a heavy chewer though. And he has a deer antler to chew on.
He also gets a stuffed frozen kong to keep him busy. My favorite puzzle for him is to take a rinsed out 2L soda bottle and put small treats or kibble in it. It'll be loud as he bats it around, but it takes him 30-45 min to get his dinner (1/3c) out of the bottle. The shape makes it challenging. I sometimes crinkle it a little to make it harder.
