The Quarab Horse is a breed from the United States which was developed from a 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 (an even cross between the Arabian and stock horse types), Stock (a heavier emphasis on stock horse breeding) and Pleasure (a heavier emphasis on Arabian breeding).
The first Quarab registry was formed in 1984, even though there have been records of crosses between the three breeds throughout the history of their respective registries. The first Quarab registry later went out of business and 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.
There are Quarab Horses that are found to have characteristics of both Arabian and stock horse (Quarter Horse or Paint Horse) bloodlines. The characteristics of Quarab Horses are based on the ratio of Arabian to stock horse blood. The more Arabian types tend to have longer necks and barrels and level croups, however, the more stock horse types do tend to have more muscular legs and rounded croups.
When it comes to their height, these horses can range from 14 to 16 hands (56 to 64 inches, 142 to 163 cm). The International Quarab Horse Association accepts horses of all colors and patterns, with the exception of leopard complex spotting, which is not accepted.
There are three recognized types of Quarabs: Straight or Foundation, Stock and Pleasure. Straight/Foundation horses are an almost even blend of Arabian and stock horse traits, showing the influence of both bloodlines equally. This type is sought by most breeders, and is the type on which the registry standard is based. The Stock type Quarab has a greater amount of either Quarter or Paint horse breeding and traits; this type is often used by ranchers and Western riding breeders. The Pleasure type shows a strong Arabian influence, with less traits from the stock horse - these horses are often favored by endurance riders.
