Bought this for my large American Bulldog - she didn't like it at first and I was a bit disappointed because of the expense, but now its one of her favorite toys. She brings it to me when she wants to play fetch, loves to shake it like crazy with the rope and the irregular bouncing keeps her interest. We've had it nearly a year and it has held up - she doesn't chew her toys other than the rough play. I only rated it a four because it's a bit expensive - but it has lasted longer than her other balls....so worth it.
