Markings on horse
Horse
The horse is one of two extant subspecies of Equus ferus, or the wild horse. It is a single-hooved mammal belonging to the taxonomic family Equidae. The horse has evolved over the past 45 to 55 million years from a small multi-toed creature into the large, single-toed animal of today...

. Most horses have some markings, and they help to identify the horse as a unique individual. Markings are present at birth and do not change over the course of the horse's life. Most markings have pink skin underneath most of the white hairs, though a few faint markings may occasionally have white hair with no underlying pink skin. Markings may appear to change slightly when a horse grows or sheds its winter coat, however the difference is simply a factor of hair coat length, the underlying design does not change.

On a gray horse
Gray (horse)
Gray or grey is a coat color of horses characterized by progressive silvering of the colored hairs of the coat. Most gray horses have black skin and dark eyes; unlike many depigmentation genes, gray does not affect skin or eye color Their adult hair coat is white, dappled, or white intermingled...

, markings visible at birth may become hidden as the horse turns white with age, but markings can still be determined by trimming the horse's hair closely, then wetting down the coat to see where there is pink skin and black skin under the hair.

Facial markings

Facial markings are usually described by shape and location. There may be more than one distinct facial marking and if so, will be named separately. Occasionally, when a white marking extends over an eye, that eye may be blue instead of brown, though this is not consistently seen in all cases.

Common facial markings are:
  • Blaze: a wide white stripe down the middle of the face.
  • Strip, stripe, or race: a narrow white stripe down the middle of the face.
  • Bald Face: a very wide blaze, extending to or past the eyes. Some, but not all, bald faced horses also have blue eyes.
  • Star: a white marking between or above the eyes. If a stripe or blaze is present, a star must be significantly wider than the vertical marking to be designated separately.
  • Snip: a white marking on the muzzle, between the nostrils.


Additional terms used to describe facial markings include the following:
  • Faint: A small, yet permanent marking that usually consists of white hairs without any underlying pink skin.
  • Interrupted: A marking, usually a strip or blaze, that is broken and not solid for the entire length of the face.
  • Connected: Occasionally used to describe distinctively different markings that happen to be joined to one another
  • Irregular or crooked: A marking, usually a strip or blaze, that does not have a more or less straight path.
  • Lip markings: have no specialized names, usually are described by location, such as "lower lip," "chin", etc. Lip markings may indicate presence of the sabino

Leg markings

Leg markings are usually described by the highest point of the horse's leg that is covered by white. As a general rule, the horse's hoof

From tallest to shortest, common leg markings are:

  • Coronet: white just above the hoof, around coronary band, usually no more than 1 inch (2.5cm) above the hoof.

Additional terms used to describe white leg markings include:
  • Irregular: A marking within the broad confines of a given height, but with significantly uneven edges. Indicated by the highest point of the white. Most often used to describe certain types of stockings.
  • Partial: An irregular marking that only extends up part of the leg to the height indicated, sometimes with the other side of the leg dark. Usually used to describe socks and other short markings.

Horses may develop white markings over areas where there was an injury to the animal, either to cover scar tissue from a cut or abrasion, or to reflect harm to the underlying skin or nerves.

Natural markings

Birdcatcher spots are small white spots, usually between 1 mm and 1 inch (25.4 mm) in diameter. It is not yet known what controls their expression, although it is believed that they are not genetic. Birdcatcher spots occur in many breeds. These spots may occur late in a horse's life, or may occur and then disappear.

Ticking or Birdcatcher ticks are markings that involves white flecks of hair at the flank, and white hairs at the base of the tail, called a "skunk tail". These patterns are permanent and probably genetic. It is thought that this roaning

     horses often develop patches of solid (dark) hair on the roan sections of their bodies wherever there has been any scratch or damage to underlying skin, even if only slight. These are sometimes called "corn marks" or "corn spots."


Scarring on a horse usually results in white hairs growing in over the injured area, though occasionally there may be no hair growth over the scar at all.
  • Saddle marks may be seen on the back or withers as a patch of white hairs, usually a result of wearing an improperly-fitted saddle for long periods, but also could be related to straightforward long-term saddle wear, unclean saddle blankets and other causes. White marks just forward of the withers may be the result of an ill-fitting horse blanket

    s), can also be used to identify a horse.

Other identifying features

Horses can be uniquely identified by more than just markings or brands. A few other physical characteristics sometimes used to distinguish a horse from another are:
  • Whorls, colloquially known as "cowlicks": divergent or convergent patches of hair found anywhere on the body but mostly on the head, neck, chest, belly, or just in front of the stifles.
  • "Glass" eye, "Moon" eye, "China" eye, "Wall" eye or "Night" eye: A blue eye. Horses with blue eyes are less common than horses with brown eyes, but can see equally well.
  • Chestnuts
    Chestnut (horse anatomy)

    : A callous-like area on the inside of the horse's leg that has a subtle pattern, but one unique to each horse. It has been proposed that chestnuts could be used as a type of "fingerprint" to identify a horse, but the idea has failed to become widespread in practice, probably in part because the chestnut continually grows and sheds, making precise measurement a challenge.
  • "Prophet's thumbs," or muscle dimples, are small indentations in the muscle, usually found on the horse's neck.

Coat Colors with distinctive patterns

Some horse coat colors are distinguished by unique patterns. However, even for horses with coat colors that are arranged in a manner unique to each individual horse, these patterns are not called "markings." Some coat colors partially distinguished by unique patterning include:
