WHAT I LEARNED
Color: U.S.A, Size: Medium
i AM NOT SURE THAT 4 STARS IS A FAIR SCORE, MY DOG IS AN AGGRESSIVE CHEWER, NEEDLESS TO SAY WITHIN 2 DAYS ALL THE TABS WERE OFF, BUT THERE WERE NUBS LEFT AND SHE CAN USE THAT. HERE IS A WHAT NOT TO DO, BRING IT TO THE DOG PARK, THEY ALL HAVE A BLAST BUT IF YOUR A BULLY/PIT MIX AND DECIDE TO SINK THEIR TEETH INTO IT, IT DOES DEFLAT. LESSONS LEARNED STILL A FUN TOY.

Sturdy ball with pump
Color: Black/White, Size: Medium
Thick material so it won't pop so easy. Comes with a hand pump and 2 ball needles. Tabs for the dog to carry in his mouth. Although my dog bites the whole thing to carry. Savage loves it!
