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.

Great Product
My Dog loves this thing, and he tears up everything he gets a hold of, all the time. This thing has been durable like no other toy we have bought for him. Great product, highly recommend, and I would definitely buy it again, but I don’t think I’ll have to because this thing is built to last.

Heavy for small dogs
Great play toy for dogs, too big and heavy for a 5 pound dog
