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.
