BUILT FOR GENTLE CHEWERS This high-flying disc is lightweight yet tough. The Zisc is gentle on dog's mouths; it's soft, pliable, floatable, and flies far. Zisc is tough enough to handle zoomies but gentle on teeth and gums. The bright colors are perfect for spotting in the grass at the park or mysteriously wedged between the couch cushions. It bounces, it floats, and when it gets that inevitable layer of slobber, just toss it in the dishwasher.
