For some reason, these are my dog's favorite balls. If he can't find one, he searches everywhere and really doesn't want to play with tennis balls or anything of a different texture. These are smooth - they are lightweight and don't last forever, but at this price, that's fine. He doesn't destroy them intentionally.
These balls are AMAZING! when we lose Lolas, she will seriously just lay around and whimper until we go buy her new ones. I tried buying her Tennis balls, and other kinds but it just is not the same. They are cheap, very durable for the amount of play they get at our house, and DEFF worth the money.
