The Pinto Horse Association of America (PtHA) registers horses, utility horses, ponies and miniature horses of various pedigrees with certain kinds of pinto coat colors. The word pinto is Spanish for "paint." In general terms, pinto can apply to any horse marked with unpigmented pink-skinned, white-haired areas on its coat. The Pinto Horse Association of America provides the owners and riders of pintos with a show circuit and a breed organization. The primary requirement for PtHA registration is coat color; the pinto is not a true breed, but a color breed.
This registry is distinct from the American Paint Horse Association, which registers Paint horses. The Paint Horse is bred as a stock horse suitable for western riding, and comes from American Quarter Horse and Thoroughbred lineage. The Pinto Horse Association of America does not specialize solely in stock horse breeding, though some PtHA-registered horses are stock horses. Most horses with the recognized color pattern registered by the American Paint Horse Association qualify for the PtHA as well, though the reverse is not true.
The Pinto Horse Association of America was formed in 1956 for "colored" horses. The aim of the association was to provide a competition venue for spotted horses and to track their pedigrees. [1] The need for the organization arose in part due to the exclusion of horses with excessive white, called cropouts, from many traditional breed registries. Many registries that have relaxed their regulations regarding coat color in recent years historically denied papers to some examples of the breed. Spotted horses also faced discrimination in the show ring, as solid coat colors were preferred.
To qualify for full registration with the Pinto Horse Association of America, a horse must exhibit a cumulative four square inches of white coat with underlying pink skin in the so-called "qualifying zone." The qualifying zone excludes the face from the ear to the corner of the mouth, and the corner of the mouth to the chin. The legs from the knee and hock down are also not part of the qualifying zone. Ponies must have a cumulative three square inches of pink-skinned white coat, and Miniature horses need to exhibit two square inches of such white coat. [2]
Fully registered horses are divided into two categories: Tobiano and Overo. The application of these terms to PtHA Pinto horses is not based on genetics, but rather on a visual description. This may be because whether or not a pattern crosses the back affects how the topline is perceived visually, such as when horses are judged on their conformation. Horses that are labeled "tobiano" by the PtHA are described as having a coat that "appears to be white with large flowing spots of color, often overlapping. Spots of color typically originate from the head, chest, flank and buttock, often including the tail." [2] This definition is largely accurate in describing the genetic condition of the tobiano spotting pattern.
The Pinto Horse Association of America's designation of "overo" also depends on a visual description: "a colored horse with white markings. Spots of white appear to be jagged and usually originate on the animal's side or belly spreading toward the neck, tail, legs and back. White almost never crosses the back." [2] A variety of genetically distinct white spotting patterns produce coat colors that fit into the PtHA's "overo" category, including frame overo, which is associated with Lethal white syndrome. splashed white, sabino-type and Dominant white patterns also fit this description.
Horses which lack the minimum amount of white, but exhibit "Pinto characteristics" such as blue or parti-colored eyes, leg white above the knee or hock, white or multi-colored hooves and minimal body white may be registered as Breeding Stock. Solid white horses are also registered as Breeding Stock. [3]
The non-white areas of the coat may be listed on PtHA papers as bay, bay roan, black, blue roan, brown, buckskin, chestnut, cremello, dun, gray, grulla, palomino, perlino, red dun, red roan, seal brown, silver dapple or sorrel. [4]
Registration with the Pinto Horse Association of America is primarily based on coat color. Miniature and pony stallions, mares, and geldings may be registered with undocumented parentage, as may horse mares and geldings. Horse stallions must have documented parentage including a sire and dam registered with the PtHA itself, or as one of the following breeds: American Paint Horse, Quarter Horse, Thoroughbred, Arabian horse, National Show Horse, Morgan horse, American Saddlebred, Standardbred horse, Missouri Fox Trotter, Tennessee Walking Horse, Andalusian horse, Lusitano, Hanoverian, Holsteiner, Trakehner, Westphalian, and Oldenburg. [5]
No horses or ponies with draft horse ancestors or characteristics, or those of the Appaloosa breed (leopard complex) are permitted.
Pinto horses can be any of the major physical conformation types. For competition purposes, horses and ponies registered with the PtHA are classified by their heights and their type. Animals which measure no more than 34 inches at the withers (8.2 hands high) are classified as "Miniature"; between 34 and 38 inches (8.2 to 9.2hh) as "Miniature B"; 38 to 56 inches (9.2 to 14hh) as "Pony" and anything exceeding 14 hands high at the withers fits into the PtHA's "Horse" category.
Pleasure-type Pintos are suitable for pleasure riding and are typically of Arabian, Andalusian or Morgan breeding and conformation. Pleasure-type Pinto ponies are typically of Welsh pony, Classic Shetland pony or Arabian breeding. Some of these animals, depending on aptitude, may cross over into the Saddle type category, particularly the National Show Horse.
Saddle-type Pintos display the carriage and animation of high-stepping horse breeds, and many are gaited horses typically with Saddlebred, Hackney, or Tennessee Walker breeding and conformation. Saddle-type Pinto ponies are predominantly of American Shetland, Hackney pony or American Saddlebred breeding.
The original purpose of the Pinto Horse Association of America was to provide a competition venue for "colored" horses. [2] Horse shows open only to horses registered with the Pinto Horse Association of America are held year-round and all across the United States. [6] Pinto Horse Association shows offer a wide variety of classes in various disciplines, including western riding, saddle seat riding and driving, hunt seat riding, dressage, equitation, gymkhana, and rodeo events. [7]
Palomino is a genetic color in horses, consisting of a gold coat and white mane and tail; the degree of whiteness can vary from bright white to yellow. Genetically, the palomino color is created by a single allele of a dilution gene called the cream gene working on a "red" (chestnut) base coat. Palomino is created by a genetic mechanism of incomplete dominance, hence it is not considered true-breeding. However, most color breed registries that record palomino horses were founded before equine coat color genetics were understood as well as they are today, therefore the standard definition of a palomino is based on the visible coat color, not heritability nor the underlying presence of the dilution gene.
The American Paint Horse is a breed of horse that combines both the conformational characteristics of a western stock horse with a pinto spotting pattern of white and dark coat colors. Developed from a base of spotted horses with Quarter Horse and Thoroughbred bloodlines, the American Paint Horse Association (APHA) breed registry is now one of the largest in North America. The registry allows some non-spotted animals to be registered as "Solid Paint Bred" and considers the American Paint Horse to be a horse breed with distinct characteristics, not merely a color breed.
The Morgan horse is one of the earliest horse breeds developed in the United States. Tracing back to the foundation sire Figure, later named Justin Morgan after his best-known owner, Morgans served many roles in 19th-century American history, being used as coach horses and for harness racing, as general riding animals, and as cavalry horses during the American Civil War on both sides of the conflict. Morgans have influenced other major American breeds, including the American Quarter Horse, Tennessee Walking Horse and the Standardbred. During the 19th and 20th centuries, they were exported to other countries, including England, where a Morgan stallion influenced the breeding of the Hackney horse. In 1907, the US Department of Agriculture established the US Morgan Horse Farm near Middlebury, Vermont for the purpose of perpetuating and improving the Morgan breed; the farm was later transferred to the University of Vermont.The first breed registry was established in 1909, and since then many organizations in the US, Europe and Oceania have developed. There were estimated to be over 175,000 Morgan horses worldwide in 2005.
Lethal white syndrome (LWS), also called overo lethal white syndrome (OLWS), lethal white overo (LWO), and overo lethal white foal syndrome (OLWFS), is an autosomal genetic disorder most prevalent in the American Paint Horse. Affected foals are born after the full 11-month gestation and externally appear normal, though they have all-white or nearly all-white coats and blue eyes. However, internally, these foals have a nonfunctioning colon. Within a few hours, signs of colic appear; affected foals die within a few days. Because the death is often painful, such foals are often humanely euthanized once identified. The disease is particularly devastating because foals are born seemingly healthy after being carried to full term.
The American Saddlebred is a horse breed from the United States. This breed is referred to as the "Horse America Made". Descended from riding-type horses bred at the time of the American Revolution, the American Saddlebred includes the Narragansett Pacer, Canadian Pacer, Morgan and Thoroughbred among its ancestors. Developed into its modern type in Kentucky, it was once known as the "Kentucky Saddler", and used extensively as an officer's mount in the American Civil War. In 1891, a breed registry was formed in the United States. Throughout the 20th century, the breed's popularity continued to grow in the United States, and exports began to South Africa and Great Britain. Since the formation of the US registry, almost 250,000 American Saddlebreds have been registered, and can now be found around the world, with separate breed registries established in Great Britain, Australia, continental Europe, and southern Africa.
Skewbald is a colour pattern of horses. A skewbald horse has a coat made up of white patches on a non-black base coat, such as chestnut, bay, or any colour besides black coat. Skewbald horses which are bay and white are sometimes called tricoloured. These horses usually have pink skin under white markings and dark skin under non-white areas. Other than colour, it is similar in appearance to the piebald pattern. Some animals also exhibit colouration of the irises of the eye that match the surrounding skin. The underlying genetic cause is related to a condition known as leucism. The term is also used to describe spotting patterns in various other animals, such as goats.
The Quarab is a horse breed from the United States, developed from a part-Arabian cross of Arabian horses, American Quarter Horses and Paint horses. Members of the breed are found that resemble all three of the foundation breeds, leading to three recognized types: Straight or Foundation, Stock and Pleasure. Although there have been records of crosses between the three breeds throughout the history of their respective registries, the first Quarab registry was formed in 1984, but later went out of business. In 1999, the International Quarab Horse Association was formed and remains the leading force in Quarab breeding. In order to be registered with the IQHA, horses must have at least 1/8 blood from both the Arabian and stock horse types.
A pinto horse has a coat color that consists of large patches of white and any other color. The distinction between "pinto" and "solid" can be tenuous, as so-called "solid" horses frequently have areas of white hair. Various cultures throughout history appear to have selectively bred for pinto patterns.
Tobiano is a spotted color pattern commonly seen in pinto horses, produced by a dominant gene. The tobiano gene produces white-haired, pink-skinned patches on a base coat color. The coloration is almost always present from birth and does not change throughout the horse's lifetime, unless the horse also carries the gray gene. It is a dominant gene, so any tobiano horse must have at least one parent who carries the tobiano gene.
Overo refers to several genetically unrelated pinto coloration patterns of white-over-dark body markings in horses, and is a term used by the American Paint Horse Association to classify a set of pinto patterns that are not tobiano. Overo is a Spanish word, originally meaning "like an egg". The most common usage refers to frame overo, but splashed white and sabino are also considered "overo". A horse with both tobiano and overo patterns is called tovero.
Sabino describes a distinct pattern of white spotting in horses. In general, Sabino patterning is visually recognized by roaning or irregular edges of white markings, belly spots, white extending past the eyes or onto the chin, white above the knees or hocks, and "splash" or "lacy" marks anywhere on the body. Some sabinos have patches of roan patterning on part of the body, especially the barrel and flanks. Some sabinos may have a dark leg or two, but many have four white legs. Sabino patterns may range from slightly bold face or leg white markings—as little as white on the chin or lower lip—to horses that are fully white.
The Spotted Saddle Horse is a horse breed from the United States that was developed by crossing Spanish-American type gaited pinto ponies with gaited horse breeds, such as the Tennessee Walking Horse. The result was a colorful, smooth-gaited horse, used in the show ring and for pleasure and trail riding. Two registries have been created for the breed, one in 1979 and the other in 1985. The two have similar registration requirements, although one has an open stud book and the other is slightly more strict with regard to parentage requirements, having a semi-closed stud book. The Spotted Saddle Horse is a light riding horse, always pinto in color. Solid-colored foals from registered parents may be registered for identification purposes, so their pinto-colored foals have documented parentage. They always perform an ambling gait, rather than a trot, in addition to the gaits of walk and canter, performed by all breeds.
The American Paint Horse Association (APHA) is a breed registry for the American Paint Horse. It is currently headquartered in Fort Worth, Texas. It was founded in 1965 with the merging of two different color breed registries that had been formed to register pinto-colored horses of Quarter Horse bloodlines. One of these organizations was the American Paint Quarter Horse Association and the other was the American Paint Stock Horse Association.
A cropout, crop-out or crop out is a horse with body spots, including pinto or leopard complex spotting, or "high white" horse markings, with a sire and dam who both appeared to have been solid-colored. There are several variations in the definition, depending on the breed registry involved. There are multiple genetic reasons that may cause a horse to be a cropout. Sometimes solid-colored horses throw cropouts because some spotting patterns are recessive genes that are not necessarily expressed unless the relevant allele is inherited from both parents. Other times a gene may be a dominant or incomplete dominant but so minimally expressed that the horse looks solid but can pass flashy color on to its offspring.
Splashed white or splash is a horse coat color pattern in the "overo" group of spotting patterns that produces pink-skinned, white markings. Many splashed whites have very modest markings, while others have the distinctive "dipped in white paint" pattern. Blue eyes are a hallmark of the pattern, and splash may account for otherwise "solid" blue-eyed horses. Splashed white occurs in a variety of geographically divergent breeds, from Morgans in North America to Kathiawari horses in India. The splashed white pattern is also associated with congenital deafness, though most splashed whites have normal hearing. Splashed white can be caused by multiple variants across two different genes, for which genetic testing is available.
The Quarter Pony is a breed of pony that is similar to the American Quarter Horse. It stands up to 14.2 hands high and was developed from American Quarter Horse foundation bloodstock. The breed was originally developed from Quarter Horses that did not meet the American Quarter Horse Association's height requirement. It is bred to look like a small Quarter Horse, although the various registries also allow crosses with other breeds, including Paint horse, Appaloosa and Pony of the Americas, all stock types. It is one of the most versatile horse breeds there are. There are three registries for the Quarter Pony, all with slightly different registration requirements. The first registry was begun in 1964, and two more were started in the 1970s. The breed is used today in a variety of Western and English riding disciplines.
Roan is a horse coat color pattern characterized by an even mixture of colored and white hairs on the body, while the head and "points"—lower legs, mane, and tail—are mostly solid-colored. Horses with roan coats have white hairs evenly intermingled throughout any other color. The head, legs, mane, and tail have fewer scattered white hairs or none at all. The roan pattern is dominantly inherited, and is found in many horse breeds. While the specific mutation responsible for roan has not been exactly identified, a DNA test can determine zygosity for roan in several breeds. True roan is always present at birth, though it may be hard to see until after the foal coat sheds out. The coat may lighten or darken from winter to summer, but unlike the gray coat color, which also begins with intermixed white and colored hairs, roans do not become progressively lighter in color as they age. The silvering effect of mixed white and colored hairs can create coats that look bluish or pinkish.
The Pintabian horse is an American part-Arabian horse breed. It has over 99% Arabian blood, but also exhibits the tobiano color pattern, which is not found in purebred Arabians. The registry began using the term "Pintabian" in 1992 and trademarked the word in 1995. which is the official registering authority for Pintabian horses worldwide.
The American Indian Horse is defined by its breed registry as a horse that may carry the ancestry of the Spanish Barb, Arabian, Mustang, or "Foundation" Appaloosa. It is the descendant of horses originally brought to the Americas by the Spanish and obtained by Native American people. The registry was created in 1961 when some breeders of Colonial Spanish Horse bloodlines considered the Spanish Mustang breeders to be departing from the original "Indian horse" phenotype. The organization was started "for the purpose of collecting, recording and preserving the pedigrees of American Indian Horses." The registry also allows the "hybrids [sic] and descendants" of the original Spanish Colonial Horse to be registered. Horses registered with other breed registries to be double-registered with this organization if the horses meet the conformation requirements.
