The Jive Dog Ball is Amazing. We have a one year old wheaten terrier who loves to chew and has destroyed and eaten every tow imaginable (even those that claim to be industructable.)
We were at a point that we had decided to no longer give Dexter any toys. Then we found the Jive Ball. He loves this toy and can chew this toy and it doesn't even leave tooth marks. Best of all, we are now able to have fun, worry free play time again.
