Raw hides chew toys or bones - what do you give?

I don't like to give any of those things an occasional kong stuffed maybe but they finish them in a few minutes and then start breaking up the rubber and I don't want them to swallow them. They might get a hoof once in awhile no problem with them but they lose interest, The baked bones last the longest and even when they lose interest they always come back to it sometimes I give bully sticks but they need to be supervised. So it really comes down to not giving them much of anything,
