We use Charlie Bear Cheese and Egg treats for rewards, and we use Nylabones for chewing. Both of our dogs will do ANYTHING for the Charlie Bears. We like them because they are small and only have about 3 calories each, so they don't mess up their diet. As for the Nylabones, they like them so much that they will fight over who gets the favorite one. How they decide which of the 4 or 5 they have out is their favorite, I don't know.
