I got this for my dad's dog, Casey. Was unsure what to expect. I'm surprised to see some bad reviews because Casey is a young, very tough chewer and she has now had her zisc for about 8 months, and besides a few non-harmful scratches and some doggy slobber, it's in perfect condition! Frisbees I've gotten her in the past were hard plastic and caused her mouth to bleed or she chewed to pieces in a matter of seconds. She carries this in and out of the house herself. She loves it and it's one of her favorite toys. I'm here to see what else I can get her similar to the zisc for christmas. I would recommend it 110 percent. And I'm not one to usually take the time to leave reviews
