What she had in mind was getting that horse to pay attention to her. Horses always listen to the boss mare on what to do next, and clearly this horse doesn't trust Linda enough and looks into the distance for help. It's important to have your horse's attention. I've never seen anything this bad from the Parelli group (not that I follow Parelli strictly). I'm not sure if Linda was under pressure from being video taped or what?? This is a pretty awful video. She has a quote that goes something like "pressure and release is the cornerstone of horse training. But how you ask and when you release is where the art of horsemanship really is" or something along those lines. She ought to practice what she preaches!
