I don't understand why you're hating on everyone who takes advice from a trainer like Clinton.
I don't know where this comes from. I don't 'hate' anyone or any method. I take it that you have not been around here (at the Horse Forum) for very long. I recommend Clinton Anderson all of the time. When people have disrespectful to downright spoiled horses on the ground, he is the one I recommend (and have for more than 10 years).
What I was trying to say is that people that 'know' horses and are qualified to train them, do not HAVE to do ground work to accomplish everything anyone else does, either in the saddle on in hand.
There seems to be a real misconception about the necessity of doing a LOT of groundwork in order to get a very broke and very respectful horse. A good horseman and trainer will get everything done correctly with little or no groundwork. They just do not need it.
I know some very respected horsemen, many who have trained and shown World Champions that do almost no groundwork and would rather have a horse brought to them that has had little or no groundwork done with them other than being halter-broke.
When I trained for the public, I preferred to have a horse brought to me that was not even halter-broke than one that had had a lot of ground handling. I used to start no less than 50 horses a year for many years. I definitely preferred them unhandled than to have been handled by someone that did not know what they were doing. It took me a LOT more time to undo the problems that a handled horse came with.
I do not dislike the methods of the modern clinicians. They work with people that do not have the experience or background to take on a green horse without getting killed. These people are safer on the ground. These are the people that use longing or leading to get a horse to go somewhere while the competent rider just rides them through it. The competent rider is not wrong for just riding the horse where he points its head and the novice is not wrong for getting off and leading the horse where they are afraid to ride it.
Every time I read that someone thinks you HAVE to get off and lead a horse that will not cross water or a bridge or go past the pigs, donkeys or lamas in someone's back yard, I see a picture of an old cowboy trying to get across a steep gulley with water or mud in it to head off the herd of cattle he is trying to gather. I can just hear him saying "Zeke! I'll go head them cows as soon as I get off and longe my horse a while so he will cross this durned gulley!" Old 'Zeke' is a good enough rider to just ride his horse there.
Neither way is wrong, but a lot of people seem to think you absolutely have to do a ton of groundwork to get a really broke horse -- and you don't!
