My black lab is ball obsessed and this has been his favorite ball for years. With the egg shape you can spin the ball and it takes wild bounces and this adds to the fun. My lab is rough on everything but he has never destroyed this ball. The only reason I keep buying more is that I live in the country and he will get side tracked and chase a rabbit or something he sees and comeback with no ball.
I have tried other balls that are weird shaped but this has by far been the best and the most fun for Milo.
