What marking extends past the fetlock and onto the cannon bone, stopping about halfway to the knee or hock?

The marking that extends past the fetlock and onto the cannon bone, stopping about halfway to the knee or hock, is referred to as a half-stocking. This type of marking is characterized by its specific location on the horse’s leg, providing a distinction between it and other markings. A half-stocking typically covers part of the cannon bone while leaving the upper part of the leg exposed, which helps in the identification and evaluation of individual horses based on their unique coat patterns.

In contrast, a full stocking would cover the leg all the way up to the knee or hock, while a snip is a small white marking usually located on the horse's nose. A pastern marking covers only the area around the pastern joint, which is lower than the fetlock. Each of these markings serves as a unique identifier for horses but is distinct in terms of their coverage and location on the horse's body.
