The ball is fine, the perfect size, but in my specific case my dog would get scared every time she jumped. He has not tried to break it down so that he can boat, he has directly bitten it. He does not use it for what is supposed to be used but he loves it because he can pick it up with his teeth in many places and throw it into the air. So, it's not what I expected, but he still likes it very much. Plastic is hard, as more people have already commented. For the price it has is very good
