Dog loves it
Size: 10.5 inch Rubber Flex Tread
I would buy this again and again. It’s extremely durable and has held up great with my 9 month old Saint Bernard puppy. We even call it his “pacifier” because every night he grabs it and chews on it until he falls asleep. Definitely a favorite in our house!

Tough toy, but the yellow tire broke at the seam
Size: 10.5 inch Rubber Flex Tread
It was fun while it lasted and it got a lot of use, but it finally gave out after 6+/- months? Great tug toy. My dog is a 70# mutt with a strong bite and he's chewed through pretty much every other toy he's ever had. This one lasted longer than any of the others by quite a bit. He did zero chew damage to the tires, but the yellow tire in the middle broke at the seam. No tear, the seam just came undone at 90 degree angles. I'm going to look for something else this time but this wasn't bad considering how long it lasted and it wasn't very expensive. If I don't find anything tougher, I may purchase another one of these down the road.

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.
