This method does work in very certain special cases. I'd try very hard not to use it as you're just asking for a high-headed, or worse, rearing horse. But I'd be comfortable using it on an already rearing horse if he was actually being violent, not acting out of confusion, pain, or was taught to rear at one point in his life.
I'm really confused by their contradictory teachings. Isn't it suppose to go apply little pressure and don't take it off until the horse moves/does what it's suppose to? And if it doesn't move keep increasing pressure, but never actually remove pressure until its done as that's the reward?
So if wiggling the rope is the cue for backing up and the horse doesn't respond to slight wiggle, wiggle harder? So if the release of pressure is the reward, isn't stopping the wiggle so you can get enough impulsion to smack the horse a good one just completely wrong? Watch the horse's face, the wiggle stops, he relaxes, he thinks he did good. Than wack!
And the stopping to let the horse think! Gah, he wasn't thinking about what he just learned, he was off staring at the other horses and sky and grass. And then he walked up and touched his owner on the back with no discipline, so he thinks, why can't I walk behind her any other time?
And he is rushing because he's not paying attention to the leader then all of sudden the leader is going a different away. He has to catch up. I don't find him disrespectful, I find him not being made to pay attention and acting like a young, immature horse who just hasn't been properly taught.
Also, if you listen to Linda "I don't care if he goes past me way out there, just not near" So, he's not even being taught to stay behind the shoulder. So he runs past, Flap those elbows! He runs past another time, he's backed up and smacked with the snap. Also, her whip is always waving around, probably a big reason why he doesn't rush as much with the owner, she doesn't have the whip flopping about.
When the owner is calm and not rushing and turning as fast as possible the horse does pretty well, and I think most of his problems were he wasn't paying attention and then the leader turned and he had to rush to catch up. I don't find him disrespectful, I find him not paying attention.
I hate the marketed NH. I like NH, just not the marketed NH. And it's been a bad day already, so excuse my rant
