My pit bull is a year and a half old. That should say it all... tough, active, a bit destructive when it comes to toys and rawhide treats. =) He LOVES this thing! I will put it in the closet for a while and he digs it out when he realizes it's there. He will even play with it by himself, until I take it away. It isn't made to be a chew toy, it's made be retrieved. He's had it for about 3 months and with supervised use, it has truly stood up to the test. There are only a couple small holes in it, so I'll have to replace it soon. I DID NOT EXPECT a frisbee toy to last this long. Great job and thank you!
