Seriously, if this is your definition
To me Natural Horsemanship is a title given to a type of training that is not abusive
Then we have to set about defining what is abusive, and there lies a lot of our issues.
I look at horses interacting, especially mares with their foals, and I see a lot of physical interaction, horses kick and bite each other when they are sorting out disputes, or keeping order.
I start to cringe when people talk about bits, shoes, whips and spurs being abusive, none of them are abusive to me, they CAN be abusive, but are not de facto abusive.
I want a training system that is designed to help me find the best way of training, and each horse is different, as I said on the other thread I believe, I take what works for me, and ignore what I don't.
