I have bounced around from a pigskin stick type edible thing to a dogzilla barbell shape to recently at Walmart a bacon flavored plastic edge bone-shape thing with textured rubber like stuff in the middle portion. He really digs this last one and hasn't even scratched it in a week of hard chewing. The pigskin sticks were great but when we traveled they digested slow and he would barf pieces up along with anything else in the tummy. The dogzilla barbell worked great but at the first piece I saw on the floor after a month of use out it went. We are phasing out of the chew phase thankfully.
