The Hide-A-Squirrel toy is designed to encourage your dog to interact with it by enticing the dog to try and get all of the squirrels out of the tree stump. Unfortunately my dog didn't have any interest in taking the squirrels out of the tree, as much as I encouraged him, although he was interested in the squirrels themselves. He just tossed the tree stump around for a bit, and the little squirrels were chewed to pieces within minutes.
