Good for non chewers
Color: Large size (ø 7.4")
Dog lived it for the 4 minutes before he chewed a large hole in it. Definitely not for heavy chewers.

This is actually a fantastic dog toy!
Color: Large size (ø 7.4")
I originally got this for my golden retriever. He loves all things ball-shaped and I figured the handles would make this really easy for him to carry and for me to tug. It was a fantastic hit not only with the retriever but my lab and even my older Great Dane also love this toy. It's about the size of a soccer ball and covered in a nice rubber that can be chewed off if you have a destructive player but is more than durable enough for tossing around the house or even in the yard. Chewability-wise, The Dane managed to chew a couple of chunks off the handle part but he's probably a pretty extreme example. I think this would hold up just fine for most dogs' play. I just have to supervise it with my Dane so that he doesn't chew it into a pile of rubber. The biggest surprise of this ball was the fact that it has one of those slide whistles in it that makes a noise as it tumbles and rolls around. This proved irresistible to the Golden Retriever and the Lab. Every time they hear the slide whistle inside, they get up from wherever they are and focus 100% on this ball. It has some heft to it and it bounces a little but not as much as a regular ball its size, it's fun for the little ones to play with inside but it's primarily an outdoor dog toy. The handles are big enough for a human hand to hold them comfortably. It rolls in a hard-to-predict way that is extra helpful for the smaller dogs to chase.

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.
