Our Ausie chews toys up within hours, or days at best. He loves to play frisbee, but unless we put them up, he destroys them within a few days. We got him a large "Zisc" for Christmas and it's still alive and well and we don't take it away from him. He absolutely loves it. We tracked this site down to buy 2 more, smalls...one for the car, and one for the front yard. It's not the best frisbee flyer, but it's tuff as steel. In fact we're banking on the Zisc success to try their balls and the triple ball toy.
