I do NOT get what they are trying to accomplish with the horse. Maybe it's because I'm watching it without the sound out of respect for others in the room? But what the hell is this woman doing? This is what I see: Horse walking calmly behind her, so she starts violently flailing the lead at him, horse gets really tense, and she continues to flail it.
What the heck is going on here?
You totally missed the actions that caused them to ask the horse to back off...horse rushes forward and passed handler, or rushes up against handler, pushes at handler, etc...THESE are the actions they were retraining the horse against. When he was walking nicely, they left him alone. Yes, they were still teaching him to back off per cue (which started with a light lead shake), it was only when he persisted in pushing against that, and still went rushing foward and evaded what the handler (s) were asking, that they upped the level of the cue.
I don't see fear in that horse...and I think some people tend to think that ask, tell, demand is "too hard" for a horse to understand. I don't. What do horses do to each other in the pasture? Pin an ear, and look in the direction of the horse being 'asked' to move, if that don't work a few steps toward horse, and if that don't work, the horse telling other horse to move, steps into action; either biting or by kicking the other horse to make him MOVE NOW! I am totally "for" being as kind as I can to a horse, but I WILL be as firm as necessary to keep myself, AND the horse out of danger, and being injured. If that means the occasional pop by a lead rope clip so be it, because I would prefer to have the horse aware of me, than running over or right by me, like the Arab in this video. That's asking for trouble...more so for the handler, but the horse could get loose, and be in even more danger, so the street goes both ways.
Now am I 'into' the NH craze? No, because I've used alot of similar methods since I was a kid, and was taught those methods by other trainers who had been in the training business for years and years prior to that...I prefer to call it common sense and just good horsemanship. NH, if you want to call it that has been around for years and years...it's just that popular trainers have made it more "well known".
