long reining a horse

Question

long reining a horse   hello sir, what are the benefits of long reining a horse?

Answer
hi -- by long reining or line driving the horse you are getting the horse use to the bit in his mouth,  you follow behind and as you turn the horse with the reins you teach the horse about the pressure of the bit in his mouth and he learns what you want him to do, by turning left or right and stopping  etc.  thanks ED HESS
