My experience with horses has been ongoing for over 30 years. I was first taught in the "soft train" method by my grandfather.
He taught me to ride at a very young age and believed in gentle training. It was through his teachings that I learned there are wrong ways to teach a horse.
If you come across someone who claims they "break" horses, they probably do just that. They break your horse's spirit instead of encouraging your horse to bond with you. "Breaking" your horse teaches force. Force creates an animal that acts upon fear and consequently will create a negative attitude. Both owner and animal will ultimately be frustrated in the end.
