I’ve bought so many of these, our 65lb golden loves them. She also loves to leave them outside in bushes never to be found again. She also seems to love just carrying them around like they are her therapy toy, They stand up to a LOT of chewing while playing fetch, and sometimes on the way back in the house. I’ve never seen a puncture but wouldn’t suggest leaving them unattended or using them as chew toys. They bounce great on packed dirt and have a faint whistle if thrown hard enough.
