Puncture resistant Jaws dog frisbee disc

The Jaws dog disc frisbee is really tough. We have a testing lab here with 11 Pembroke Welsh Corgis. Few toys stand the test of time with our crew. Thought when we were given a sample who would pay 15.95 for a frisbee, but they outlast any pet store frisbee by years. Only thing bad is we have 4 of these in our pond somewhere.
