Conformational term. The point of the croup is visibly higher or lower then the point of the withers. If the withers are higher than the croup a horse is said to be over-built in front, if the withers are lower than the croup it is over-built behind (croup-high). During growth, young horses are frequently 'unlevel' with the croup and the withers at unequal heights, this may be regarded as normal.
