I got this toy because my golden Cody started chewing up books and other things when home alone and bored. He loves his "food cube" and knows to go get it when I ask for it. It took him about 5 minutes to figure this out, we put it on the easiest setting for that first time, after a week we had to put it on the "Max" setting, because he just emptied it too fast. It definately works better on carpeted floors, is super noisy, and gets stuck under or behind things and t hen he can't figure out how to get it out. I can't leave him alone with it because he seems to like to perform, if I leave the room he gets bored with it and won't play again until I come back to watch him. My only complaint with this is that I haven't been able to figure out how to get the thing open to clean it. Its supposed to be easy to do, but all I end up doing is hurting my fingers trying.
