Instructions
Position the saddle tree--which refers to the frame on which the saddle is built-- just above the horse's shoulder bone or scapula. The shoulder bone points upward at the base of the horse's hairline and usually forms a prominent hump in the shoulder. The front or pommel of the saddle tree should be just above the bone so that the weight is evenly distributed across the shoulders. The horn should line up directly between the horse's ears and not slip from side to side.
Place a horse blanket or other suitable padding under the saddle before strapping on the stirrups and bridle. The padding provides space between the saddle and the horse thus allowing the horse's skin to breathe.
Check the saddle to assure it is the proper size for your horse. The saddle should be wide enough to sit across the horse's spine without slipping or leaning to one side. A professional saddler can measure your horse and custom-make a saddle. The length of the saddle is also important. The rear of the saddle or cantle should be six inches to one foot from the start of the horse's haunches. If the saddle is too long, extra weight will press on the horse's spine and back legs.
Strap the saddle on by securing the straps underneath the horse. The saddle should fit snugly but not so tightly as to rub the horse's skin raw or strain it when the horse breathes. The rule of thumb is that you should be able to place two fingers easily under the stirrup cinch so that the horse has enough room.
Proper Position of a Western Saddle
The Western saddle is standard in most North American horse riding events and the most popular choice for personal use. While there are many variations of this saddle design for different activities, the Western saddle is distinct and recognizable. The saddle horn is one of its more prominent features. It protrudes from the center of the saddle in the front and is designed to prevent the rider from sliding forward onto the horse's neck. The Western saddle is designed to comfortable for both the horse and rider, but it requires proper positioning and placement. An improperly positioned saddle places strain on the horse and rider and can cause serious injury or saddle wear.
