To me Natural Horsemanship is a title given to a type of training that is not abusive. Now, I don't know where this name originated and agree that now it is used quite freely to market certain trainers products. I also feel that is just the world we live in today. Everything you own was probably advertised at one time or another. Is that why you bought the product? Who knows.
How is Natural Horsemanship different than other types of training? Well first I don't personally know any of you so I don't know what techniques you use. Are you using techniques that are "natural"? I'm sure all trainers use some techniques that are. But, I think only you can answer what type of trainer you are.
There you go. Bash away.
For those of you that know how to have a conservation (Conversation is a form of interactive, spontaneous communication between two or more people who are following rules of etiquette. It is polite give and take of subjects thought of by people talking with each other for company.) then I look forward to your opinions.
