I saw these yesterday, checked they were grain free, and bought some. One box, regular size, of "clean apple crisp," and one box, regular size, "clean carrot crunch."

This evening, I opened the apple ones, cut in half and delivered. WOW, all 4 pups ran happily off to their respective corners and had a blast! Kept them busy for 15 minutes.
