There's a round Kong with lots of slits that you can stuff pieces of treats inside (food is too small and is too easily dispensed)....mine have never like the regular big Kongs or the Nylabone type stuff. You're on the right track in finding something to replace her "rock fetish". I remember a neighborhood Golden when I was growing up....I don't think I ever saw her without a tennis ball in her mouth....back when kids and dawgs ran wild
