"The Whoopi dog is a an 11 yr old chocolate lab that loves to chase her ball. Tennis balls were no match for this retriever. Rolling around in the grass and chewing on the ball left nothing to be chased after a few throws. The last Kong Ball dog toy lasted for well over a year until the jealous dogs next door snuck into the yard one night and "stole" it....Had to purchase another one to put the smile back on the muzzle of an otherwise dejected pooch...lol!!!"
"I have the 3" ball, which is solid through and through. My pit absolutely loves it! It's fantastic, because he would just tear tennis balls apart. Twelve dollars on one ball, versus who knows how much on can after can of tennis balls!"
