I don't do a lot of reviews because I realize many are objective opinions. However, in this case I felt it was necessary to warn others. Our dogs are aggressive chewers. Their last rubber bones (not these) which we've purchased before, and recently purchased again, were destroyed quickly. Chunks of rubber came off the ends. Since those didn't hold up like they used to, I found these harder bones hoping they would last longer. They were able to gnaw into the hard plastic within a few minutes. This created sharp edges that cut their mouths. When I saw a bit of blood on the bones, I took them away from the dogs and threw them away. I wondered why they quit chewing on them after being so excited at first. Also, these are hard enough to damage a tooth.

Pups have shown zero interest in these toys….

Color: Purple & Blue

I would agree that these are indestructible being neither of my dogs have shown any interest in these at all. At this rate they should last forever…
