Great chew toy
Size: 10.5 inch Rubber Flex Tread
This is my second time buying the Tonka rings. My dog loves this chew toy. It does take him a bit to destroy them. I give this toy to him as a reward otherwise it be destroyed in 3 days. I have a pitty. So other dogs it should last longer. They are shin whackers and hurt when they connect. So I make sure to watch the dog and toy around small kids and elderly to be safe. They are heavy and made well.

Finally a toy we can leave out!
Size: 10.5 inch Rubber Flex Tread, Size: 10.5 inch Rubber Flex Tread
There are very few toys that we can leave out for our 11 month old golden. Which is a shame because as a small puppy, we taught him to bring us a toy to initiate play instead of nipping. Ropes or stuffies never lasted more than a few minutes so they always had to be taken away. One time he brought us a benenbone to play tug. So I tried this as a last resort. Finally something we can keep out for him! It’s not completely indestructible. He has figured out how to pull bits of tread off. But he chewed hard on it for a solid 20 minutes and it’s still intact with the exception of a few small tread pieces. Can’t say that for 99% of the other dog toys on the market! UPDATE: OK, so it's definitely not indestructible. After a few days of dedicated gnawing, he has almost chewed through the yellow ring so we can't leave him too unsupervised with it. I'm still going to leave it as 5 stars since it's the best tug toy that I have found so far and we have tried a lot! I may buy another one and just make sure I don't let him freely chew on it for any length of time.

Really wanted this toy to be better...
Size: 10.5 inch Rubber Flex Tread
I got this toy because I have 3 large dogs that all like to pull things. I can't always play with them even though they follow me everywhere wanting to play, so I saw this toy and thought it would be good because it would give them something they can tug away at with each other. I saw the thick rubber and thought it would last awhile, but I was wrong. My German Shepherd and Pyrenees mix chewed though the first tire rather quick, and before I realized, I was finding chunks of tire around the house and yard. Thankfully, none of them tried to eat it. It seems like it could be a good toy for an aggressive chewer IF they are smaller and not as strong as these large dogs are, but it did not hold up long to mine.

Buy it you won’t regret it
This is the best toy ever! My Rottie loves it and can entertain herself for quite a while. The unpredictability of its bounce when tossed keeps her guessing and moving getting lots of energy out. Great for tug as well, or roll it on flat surfaces, it’ll go forever! She love the squeaky too
