Westie LOVES this toy
Color: U.S.A, Size: Medium
My pup (Westie) adores this toy. This is actually our second one. The ball itself is resistant but the straps will be obliterated. Would definitely recommend! Totally worth the price!

Not durable
Color: Black/White, Size: Large
If you have a dog who likes to pop things then this toy isn't it. Within 5 min she had this ball popped. It was made to sound like it was durable for this type of thing but it definitely is not so just be aware. Now if you have a dog who doesn't pop things easy then this would be a good toy

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.
