It is one thing when you do something with purpose and achieve a result, what I saw Parelli do was different. It was shocking the animal for the sake of shocking it.Ummmmm..you think that "shaking the snot out of a rope" is inhumane? I am confused about your statement because then I cant understand why you would prefer the ways of the late Ray Hunt or Buck Brannaman. They too will harshly discipline a horse IF NEEDED and will use physical contact if necessary.
So you may be a little misinformed about their methods or have never actually been to a three day clinic in person, as I have several times (as well as Dennis Reis ,also of the same" camp" and I love those methods, BTW).
I had NO PROBLEM with Buck Brannaman backing my 2 year old colt all the way across the arena while WHACKING him across the chest with the end of the training rope. My colt to my surprize, had a serious hole in his manners that I had missed . Buck was asking him to do something and the colt reared and struck at Buck. I was glad to see it fixed. And I would have done the same thing. Buck didn't leave welts.. but I probably would have.
As well those guys MAY rope a horse around its neck in the round pen to get control if a horse is either trying to jump out or panicking and wont stop running. Do you think yanking a horse around to face up on a neck rope is also inhumane?
So I don't quite get it, why do you think a hard rope shaking is more inhumane that whacking a horse?
