The rider must trust the horse with proper training the horse will know exactly what to do. If you are scared, the horse can tell and he will be scared also. The horse trusts you. A horse with proper training will do what you want with the smallest of tug on the reins. Horses aren't just a random animal they can be a best friend. You can tell them your feelings and deepest secrets and they can't tell any one.
This is my blog dedicated to Horses.
