This is a picture of a horse with a saddle pad on. The correct position of a saddle pad is directly underneath the horse's saddle. A horse with a saddle pad on should have a clean saddle pad placed just behind the shoulders. A horse with a saddle pad on should have the saddle put on top of the saddle pad, and you should check to make sure that the seam of the saddle pad is lifted up into the gullet at the center of the saddle. This helps prevent pressure on the withers of a horse with a saddle pad on.
