For dirt argument: Of course I use a cloth Frisbee not outside in the dirt. We find it perfeckt for the house! My Collie Loves it flipped cardboard pieces to catch (and zurueckzuflippen) as playing cards from the wrist. Unfortunately the box was quickly ended and soft chew .... Normal rubber or plastic Frisbees he does not like, bounce him too hard in the mouth. The Flybee but is now his dearest toy in the house. It is also small enough so that it can do no great hall damages in the apartment and can be super flick at close range! Besides, I no longer befuelle it with treats. This irritated him namely! It separates feed and play meticulously! Even after the game he'd rather a delightful spoken praise and cuddly massages! American Collie flat, very people oriented. So - try material Frisbee - for all dogs with a sensitive mouth!
