We've had this Zisc frisbee for a few weeks and our 16 month chocalate lab that has destroyed many a toy, furniture etc has not put a mark on the Zisc. As recommended on another review we use for exercise only. We fly and he chases it 15-20 times until we burn off some his energy. We rinse off the dirt from the yard and were good to go the next time. We also have the huck but haven't had the need t use it yet.
