I boutgh this for my foster puppy that loves squeaky bouncy toys and she LOVES them, she carries one with her everywhere. It is great to play fetch or for her to play by herself, it keeps her occupied. For reference she is a 7m old 30lb Heeler/Pit mix and very much a puppy chewing and ripping everything off. These have hold pretty well, we've had them for a few weeks now and they are still going.
