Bailey went through a chewing phase. He probably still does, but we haven't found his destruction lately. For us it was the antlers that did the trick. As I have talked about before, these are all natural deer and or elk antlers which they shed each season. He likes the 4-5" ones that aren't too thick on one end. I got a few that are a bit wide on one side and he doesn't really like them as much. I just prefer him having antlers to bully sticks now that I know what they are!
