"I was very surprised to see a review with a one-star rating. This toy has survived use by a lab; one that can peel the decorative finish off balls, walls--you name it. It is sturdy enough to withstand extensive chewing & tossing. Putting kibble in the open end (small enough to fall into the opposite end) provides the challenge of picking up the right end of the toy to dispense a treat--or dropping it just the right way or from the right height. Two months since purchase and still having fun!"
