I had hopes for this dog puzzle. To be fair, my dog is medium size, weighs 24 lbs., and has lost a few of his small front bottom teeth. This item is too hard for him to retrieve treats. I could see him really work with it but he got really frustrated. Probably better for larger dogs with more powerful jaws. For my dog, it was not.
