Superb Toy!!!! Our 4 year old lab absolutely loves it ... in fact he has chosen this over his previous favorite (the Tux)! Durable, stretchy, fun for the dog and the family to play together... I am a HUGE fan of the zogoflex material.  In fact... the West Paw / Zogoflex toys are the only ones in our house - because they are the only ones that will last past a week or so!  The Bumi has brought great amusement, fun, laughter and entertainment to our household - our lab absolutely loves it!!!!! Would DEFINITELY buy again and again.
