18 Month old GSD doing SchH. Working on bungee tie out. Full bite, but he's either a little chewy or excessive re-grips? Not sure. I noticed during rebite he pushes his head forward. He is chewy on tug, working on that and making progress. We are going to do this for 4 weeks at 3 times a week, or 12 times and see if progress has been made. Comments welcome.
