coup de hache

CONT: A horse with a short neck set on low, but carried high (so that there is a noticeable dip in front of the withers and outward bulge under the neck) will be more inclined to do a high action gait in some ventroflexion (hollow body position) than one with a neck set on low and carried low.
CONT: The ewe neck is the one whose underneck shows a considerable bulge, while its topline shows a dip in front of the withers.
