My dogs love Petstages Durable Sticks . They are not as hard as a Nylabone but not soft enough to break pieces off . They just slowly wear down as the dog chews . The most my dogs have gotten off are shavings .. My Airedale is an extremely aggressive chewer and he can't break it up . Petstages Durable Stick Dog Chew Toy, Medium
Here is Oscar chewing his durable stick ..
