Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Aggressive chewers have met their match.
Size: 10.5 inch Rubber Flex Tread
We purchased this toy in 2022, it finally broke last night. Four years of rough play with 2 boxers who are aggressive chewers. They would tug together, gnaw on it for hours, and often leave it outside exposed to the elements, but this toy just kept going. It was by far their favorite toy, it kept them busy for hours. I just ordered a replacement. Well worth the money, perfect size. Highly recommend.

Durable, fun, and safe for my dog
Size: 10.5 inch Rubber Flex Tread
I have a 10 month old, 50 lb mutt who has the musculature of a pit bull and the muzzle of a GSD. Buttercup’s favorite past-time is shredding toys into teeny tiny bits, but sometimes those bits don’t come back out of her mouth. She can’t have tennis balls, stuffies, anything with a squeaker, silicone toys, plastic toys, rubber toys with spikes or small appendages, anything with rope, or most chews & bones. She chewed her first and only $8+ XL bully stick like a corn chip. Finding indoor enrichment is a challenge. Buttercup is extremely pleased with this tire tug thingy, it is very ergonomic for both her and me to get a handle on it, it has more movement than any other toy she can safely have, and it’s very durable. After more than a week, there’s only a little bit of tread missing, which is definitely the best-case outcome with a super chewer. I think this is a good alternative to GoNut toys because it’s solid & dense while also a little bit easier & more interesting to play with, and very unlike GoNuts, this Tonka toy is very reasonably priced. I also think this it’s a good size for almost any breed of dog—I could definitely picture a little Boston or Frenchie dangling from one end. Highly recommended!

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.
