I love this toy.
It comes in three sizes and it cannot be destroyed, at least my dogs have not been able to break them and believe me they destroy toys fast. But this ball is fabulous. It does not open up so what you do is find the right size treat and put them in the ball thru the holes and hand it over.
I purchase mine from.....
www.busydogball.com
sizes:
2" ball for tiny to small dogs
4" ball for medium dogs
7" ball for larger dogs
CAUTION: Do not buy a ball that fits inside your dogs mouth. buy the ball a bigger size :)
