The one bone to rule them all
This bone is definitely the favorite of all the different rubber bones we’ve tried. In fact, we did a green rubber bone test of two we bought to replace an old one and it was a clear winner. I don’t think it’s a matter of the sqeaky getting damaged as some dogs may eventually puncture the bone itself and then it won’t squeak. My little goober has serious teeth and she cannot stop squeaking this one. Also it bounces and I can throw it pretty far.

A replacement
This is a replacement for one my dog wore out after a year. This toy is great 👍 it is made very well. Our dog loves the squeaker and resists constant chewing. Lasted a year lol 😆
