They are not kidding, this ball is truly indestructible. I've gotten several for my dogs so they have plenty to share. Two of my dogs are beyond super chewers (bully breeds). One of the balls is missing the section that's glued into most of them, but the structure has still held up. And my dogs LOVE them.

Tough STINKY ball

Size: Large, Color: Red

This ball is the only one I've found that my dog can not destroy in seconds. He can chew on it for a few weeks before he works a hole in it. That's the good part. The bad side is the horrible smell! It doesn't seem to bother him, but it is horrible to my nose. It is so awful that I tried soaking it and dish soap and vinegar water overnight to see if I could make it go away. It was a little bit better but still stunk. Anybody got other suggestions on what could make the smell go away?

A good toy for chewers!!

Size: Large, Color: Blue

My dog loves this ball! The best part is that he hasn't destroyed it yet. He's a real chewer and has destroyed several toys since I got him about 6 months ago. The ball is very solid and a the squeak is not annoying. A great toy

My dog loves it, holds up well

Size: Large, Color: Blue

My German Shepherd absolutely loves this ball! He is a pretty aggressive chewer and it has held up really well, not indestructible but it lasts. We currently have three and he always has one in his mouth.

Lasted a year with a Great Dane

Size: Large, Color: Red, Size: Large, Color: Red

It lasted an entire year as my Great Dane’s favorite squeaky ball. The only reason it’s failing is because the squeaker no longer works great.
