How is a half pastern marking defined?

A half pastern marking is defined as a white marking that covers only one half of the pastern joint. The pastern is the area of a horse’s leg between the fetlock and the hoof, and a marking in this area can vary in size and coverage. In this case, "half" indicates that the marking does not extend to the full joint, which helps differentiate it from a full pastern marking that would cover the entire joint. Understanding these markings is important in equine identification and assessment, as accurate descriptions contribute to the proper classification and understanding of individual horses.
