The Science of Breast collars Used to keep the saddle from slipping backwards or as a safety measure to give the rider time to dismount in case a cinch or billet breaks. Western work with cattle requires a sturdier, thicker breast collar than English riding, which uses thinner straps of leather.Usually attached to the D rings that hold the latigo of the cinch. May also have a leather strap that goes betwen the horse's front legs and attaches to the cinch. Can be very decorative such as when used in full parade dress or just functional. When fitting your breast collar, attention should be paid to the shoulders, chest, and the area between the front legs of your horse. You do not want to restrict movement in the front or cause irritation. In general you should be able to fit your fist between the breastplate and the horse's chest and a hand's width between the wither strap and the withers. Be sure the buckles don' t rub and that the chest straps lie ABOVE the point of the shoulder so you don't restrict the motion. |
