I have kongs and jollys and they last a long time, but anything else I let my dog play with doesn't last long. He likes rope toys, but they turn to threads pretty quick. I found some rope toys made out of fleece on amazon that he plays with them all the time and they last. It's been two moths since I bought them, I've only let him have two of the five and both of those are still in good shape. According to the write up, the maker of these toys has a GSD and started making these because all the other toys got tore up so quickly. I just thought I would pass this on in case anyone is interested.
