Beau, i agree with you about the lunge... but Clinton Anderson??? it's terrible to watch! he's so agressive, poor horse, i don't understand what he wants, so how could the horse???
Yes, there are times when you could say he is aggressive with the horse. But think about how a wild herd of horses operate. When a mare gets out of line, do you think the stallion politely asks her to change her ways? NO.
He'll give her a warning look (ears pinned), and if she doesn't comply immediately, he won't hesitate to kick or bite her. Yes, you can call that aggressive, but it is how horses operate, and its how they understand.
Granted, this is a short small clip of how Clinton works with his horses, but it doesn't go into as much detail on how he is getting there like it does on his DVDs (much more step-by-step). Plus, keep in mind that this video is a short demonstration at an expo. Normally, you don't teach your horse all these things and to load in an hour. Instead, you do short 15 minutes sessions every day, working on ground manners and building on the previous result, to get the end result that may take weeks or months (depending on the horse).
The mare in the trailer loading video is VERY disrespectful. There's several instances in the video where she tries to shoulder into him and literally run him over. Again, if the horse is that
disrespectful, you are going to need to get aggressive with them to get your point across and keep yourself safe.
Really pay attention to his body posture. He is asking the horse to move with his body signals, giving them a chance to respond before he gets after them with the end of the lead rope. When this mare does the correct thing, he leaves her be. When she does something wrong (ex: run by too close to him = dangerous), he's going to correct her.
Plus, notice that CA's feet almost never move. He is making the horse do the work and move around HIM. He is telling the horse to move her shoulder, or hindquarters, or send her a certain direction, all with his body language.
Is Clinton aggressive? Absolutely (when he has to be). And with the horse in that video, who is very dangerously disrespectful, you have to be in order to achieve your end result with a horse that respects you as the leader.
But if you don't understand what you are seeing...... I can see how it looks "terrible to watch" to an untrained eye. (Granted, there's going to be people who don't like CA, just like there are people who don't like Parelli, or whoever else. There's always personal preference.)
