My mixed breed dog chews through EVERYTHING we give him. The black Kongs designed for much bigger dogs don't stand a chance with him. Tennis balls last minutes, literally. Enter the Jive - he's had this ball for a solid two weeks, and aside from some surface scratches, this ball looks exactly the way it did when we bought it. I love that I have a toy I can allow my dog to go to town on without keeping an eye out to make sure he hasn't shredded or swallowed any of it. This is also a great, sturdy ball to play fetch with. Teh blue color makes it easy to find wherever it lands. Thank you, West Paw!
