[question name="Tara"]I attended a short course on horse behavior at New Bolton Center where you explained how a twitch works and your recommendations for how to use it most effectively. It seemed to make so much sense why sometimes it works and sometimes it doesn’t, and especially why horses can get to hate the twitch. Can you describe that in your column in The Horse magazine so I can show my employees and refer friends to their web site? I think it would be helpful if you could show the timeline for the endorphins that are released when the twitch is used. Also, please go over the part about how to fix a horse that is difficult or impossible to twitch.
