THE BREED STANDARD
The National Show Horse shall strive to produce an athletic horse which retains size, beauty and refinement. Specifically, the following traits are desirable:
A. Motion - Balanced and obvious power from the hind-quarters flowing into an elevated front end, the front legs showing both flexion and extension;
B. Neck - Very long, set high on the shoulder and relatively upright with fine throatlatch. The neck should be shapely but without a pronounced crest;
C. Head - Relatively small, short and refined with large eyes and small, well placed ears and a straight or slightly concave profile (a "roman nosed" or convex profile is not desirable);
D. Pronounced withers and a very deep and well laid-back shoulder;
E. Proportionately short back closely coupled with a long hip and relatively level top line (moderately sloping croup not to be penalized);
F. Legs - Correct from all angels with long forearms and short cannon bones in front and long, well-angled pasterns front and rear;
G. Refinement of bone but not lacking in substance, especially in the chest, girth, shoulder and hip;
H. A relatively high-set tail, natural and flowing;
I. When observed at rest or in motion, the horse must exhibit a natural presence and, when animated, extreme brilliance. The horse must exhibit high carriage when showing or relaxed.
