This looks like a lot more fun than a Buster Cube, because it seems like it would roll more easily, and make it more likely that dogs would figure out that it's the rolling that makes it dispense treats. And if Pretzel can carry it bigger dogs like mine would have no trouble picking it up either.
I had a wonderful boy who loved the Buster Cube, but thought he could make it dispense treats by barking at it. He was so funny. It's been a little over five years now. Excuse me. I have something in my eye.
