See our "Focus Group" - www.youtube.com/watch?v=b9Ovei8M3m4&feature=youtu.be. Potentially avoids boredom for a period of time. Boredom is often the cause destructive behavior and anxiety. Initially, the toy is a bit slippery when new so some dogs can open the GameChanger. You can use a zip-tie run through all 4 holes which should keep it closed. After a few weeks of chewing and/or if it is left outside, the toy becomes less smooth and then harder to open.
