I keep hearing different definitions of 'natural horsemanship' but none that I actually feel fits.
Horsemanship isn't 'natural' however you look at it. Being ridden is one of the most UNnatural things for a horse to put up with.
Some people feel that natural horsemanship is simply training while keeping the horse's natural instincts in mind. Using herd dynamics in order to reach one's goals. But that is no different than regular horsemanship.
Some people feel that natural horsemanship is training with the least amount of force and gadgets possible. But that is no different than regular horsemanship.
The conclusion I've come to is that 'natural horsemanship' is nothing more than a brand name people use in order to make money. Not saying that the actual training they are trying to advertise is phooey, but a lot of it is simple brand power.
The old school trainers (Ray Hunt, the Dorrance brothers, Buck Brannan) never used the term 'Natural Horsemanship'. They just called it 'horsemanship'.
Good training is good training. Going back to ancient Greece, using the 'popular' definition of natural horsemanship, one could argue that Xenophon was the first real natural horsemanship trainer.
I guess what I'm trying to get to is where does regular 'common sense training' end and 'natural horsemanship' begin?
