My labs dont try to destroy stuff. They just like to gnaw on something once in awhile. This has lasted a very long time. Has the typical dents and other gnaw marks, but has otherwise withstood the test of time. The different texture (very firm but with mild "give") and spots to focus on has made this a favorite go-to toy when the need to gnaw comes about. We often do bully sticks and yak chews for the majority of their chewing needs, but the nylon style also seems to hit the spot.
