Indestructible Frisbee My Mastiffs Break All Toys. Can Find Few Indestructible Toys For Them, But They Are Getting A Little Bored.?

My mastiffs break all toys. Can find few indestructible toys for them, but they are getting a little bored.? - indestructible frisbee

I have 2 English Mastiff. They are still puppies, but the beginning of all cable, stuffed animals, etc. I have successfully Kong (was black), a floating rubber bone, a thigh bone and a bone Nyla. I was a football, soccer and softball. A Frisbee, motocross tires, and two balls and rope toys hanging from a tree. They seem to be annoying (especially inside) and I wonder if it is not a cheap toy indestructible. They love to play with them, but keep the tears over her and her big money to buy them. Ideas?
