The Paso Fino is a naturally gaited light horse breed dating back to horses imported to the Caribbean from Spain. Pasos are prized for their smooth, natural, four-beat, lateral ambling gait; they are used in many disciplines, but are especially popular for trail riding. In the United States two main groups of horses are popularly called "Paso Fino:" One, also known as the Pure Puerto Rican Paso Fino (PPR), originated in Puerto Rico. The other, often called the Colombian Paso Fino or Colombian Criollo Horse (CCC), developed in Colombia. Though from similar Spanish ancestors, the two groups developed independently of one another in their home nations.
These two groups have been frequently crossbred in the United States and Europe. In recent years, a trend has developed favoring preservation breeding to preserve the undiluted bloodlines of each group.
The Paso Fino name means 'fine step'. The Paso Fino is a blend of the Barb, Spanish Jennet, and Andalusian horse and was bred by Spanish land owners in Puerto Rico and Colombia to be used in the plantations because of their endurance and comfortable ride. All Pasos share their heritage with the Peruvian Paso, the American Mustangs, and other descendants of Colonial Spanish Horses. Puerto Rican and Colombian horses, as well as Paso Finos from Cuba and other tropical countries, have been interbred frequently in the United States to produce the modern American Paso Fino show horse.
