One of his favorite chew toys!
Durable for aggressive chewers! I'm glad I purchased this dog toy and I'd definitely buy it again,... however i don't think he'll ever destroy this one... So we're good here!

Poor quality.
The little nodes on the ring break off and my dog ate them. Hopefully it will pass.

Not for super aggressive chewers even though..
My 10 month old Mastiff chewed this pretty well for a couple hours but I had to take it away from him as it has pieces missing and its not a complete ring anymore.
Definitely not indestructible or even close to indestructible.
I was sure hoping though. But nope.
