Hyperflite's Jawz Pup disc is the toughest and best-flying puncture-resistant disc ever made. The Jawz Pup disc stands up to gnashing canine teeth better than any other competition disc. The Jawz Hyperflex Pup disc is an ultra-flexible version of the Jawz Pup disc that is about 80% as tough as the regular Jawz Pup disc but soft like Hypeflite's SofFlite Pup disc. Now the Jawz Pup comes in the popular glow plastic, allowing you to play catch until all hours of the night. Although the Jawz Pup disc is remarkably tough in normal canine play, it is not intended to be used as a chew toy. Jawz Pup discs do not float in water.
