The Criollo (in Spanish), or Crioulo (in Portuguese), is the native horse of Uruguay (1910), Argentina (1918), Brazil (1932) and Paraguay. It may have the best endurance of any horse breed in the world next to the Arabian. In fact, due to the criollo's low basal metabolism, it may be a better long-distance horse than the Arabian in prolonged races over a week in duration with no supplemental feed. The breed, known for its hardiness and stamina, is most popular in its home countries.

The word criollo originally referred to human and animals of pure-bred Spanish ancestry that were born in the Americas, or, in Portuguese crioulo, to animals or slaves born in the Americas. In time, the meaning of the word would simply come to refer to native breeds of the Americas.

Breed characteristics

The criollo is a hardy horse with a brawny and strong body with broad chest and well-sprung ribs. They have sloping strong shoulders with muscular necks, short and strong legs with good bone structure and resistant joints, low-set hocks and sound hard feet. The medium to large size long-muzzled head has a straight or slightly convex profile with wide-set eyes. The croup is sloping, the haunches well-muscled, and the back, short with a strong loin.

The criollo is tractable, intelligent, willing and sensible. Criollo horses average 14.3 hands high, being the maximum height for stallions and geldings of 14 to 15 hands high. The difference between the maximum and minimum height for mares is approximately 2 cm (one inch). The line-backed dun is the most popular colour, but the breed may also come in bay, brown, black, chestnut, grullo, buckskin, palomino, blue or strawberry roan, gray and overo colours.

The breed is famous for their endurance capabilities and ability to live in harsh conditions, as their homeland has both extreme heat and cold weather. They are frugal eaters, thriving on little grass. They have good resistance to disease and are long-lived horses.

Breed history

The breed dates back to a 1535 shipment of 100 Pure Bred Spaniards - Andalusian stallions coming from Cadiz, Spain, to the Rio de la Plata imported by Buenos Aires founder, Pedro de Mendoza.

In 1540, Indian hostility forced the Spaniards to abandon Buenos Aires and release 12 to 45 horses. When Buenos Aires was resettled in 1580, it is estimated that the feral horse population numbered around 12,000. Since they largely reproduced in the wild, the criollo developed into an extremely hardy horse capable to survive the extreme heat and cold, subsist with little water, and live off the dry grasses of the area. Settlers later came and started capturing horses for riding and for use as pack animals. The Native Americans had already been doing that many years before.

Throughout the 19th century a large proportion of the horses were crossed with imported European Thoroughbred, coach and draft horse stallions, and a larger, coarser, long striding multi-purpose, saddle cart horse resulted. However, the crossbreeding nearly ruined the native Spanish horse type. In 1918, the Argentine breeders decided to create a pure-bred criollos registry, and the breeder's association was then formed in 1923. Much infighting occurred between the bands of Emilio Solanet and Enrique Crotto. The first promoted the Asian type crioulo and the latter the taller African type with a coarse convex head, fallen croup, thinner mane and tail.

It was not until 1934 that Dr. Solanet was able to firmly take control of the breeders association. He set a new goal for the breed with a shorter, more compact stock horse which emulated the Chilean Horsebreed that he admired so much. In 1938, 70% of the registered crioulos were culled because they did not possess the phenotype aspired by Dr. Solanet and his followers. The new breed standard, about which he had written in 1928, was finally made available to the public once he was assured that the breeders were more united in their breed objectives. It would not be until 1957 that the registry was closed for Argentine native breeds, but the registry has remained open for the Chilean Horse breed that has been so influential in giving shape to the crioulo as a better stock horse. Nevertheless, the breed maintains its own identity in a taller, leggier and squarer body conformation with a more angular hock that gives it the long stride it requires to cover the great distances in the flat Argentine plains known as "pampas". The modern crioulo head has a straight facial profile and a shorter muzzle with longer ears than is typical in the Chilean Horse breed.


The breeders implemented rigorous endurance tests to help evaluate horses for breeding. In these events known as "La Marcha", the horses are ridden over a 750 km (466 mi) course to be completed in a 75 hours split in 14 days. No supplemental feed is allowed. The horses are required to carry heavy loads of 245 lb (110 kg) on their backs and may only eat the grass at the side of the road. At the end of the day, a veterinarian checks the horses.

Today, the horse is used mainly as a working-cow horse, but it is also considered a pleasure and trail horse which contributed a great deal to the Argentine polo pony. They are also excellent rodeo and endurance horses. The national rodeo competition is known as "paleteada", and it involves a paired team of horses and riders that approach a steer from both sides at a full run. The steer is sandwiched in between the two horses that lean onto the bovine, practically carrying it down a 60 m long delineated path beyond which the horses must not go during the defined trajectory. It is an amazing demonstration of control that can literally pick up a steer and place it wherever it needs to be.

One example of the breed's fantastic endurance was the ride made by the Swiss-born Argentine rider Professor Aimé Félix Tschiffely (1894–1954) between 1925-28. Tschiffely took two criollos, 16-year-old Mancha and 15-year-old Gato, on a 13,350 mile (21,500 km) trek from Buenos Aires to Manhattan, New York, crossing snow-capped mountains, the world's driest desert, the thickest tropical jungles, riding in all types of weather. Alternating the riding and packing between the two horses, the trio took three years to finish the trip. Although Prof. Tschiffely went through many hardships on the trip, including a bout of malaria, from the Pampas across La Quiaca, from La Paz, to Cuzco, Lima, Trujillo, Quito, Medellin and Cartagena. They rode up to 5,900 metres above sea level, through Passo El Cóndor, between Potosi and Chaliapata, (Bolivia), the horses did wonderfully well in a wide array of extreme topographies and climates. Gato lived to be 36 and Mancha, 40. They lived the last years of their lives as celebrities in La estancia El Cardal (El Cardal Ranch), the breeding establishment of the man most credited for developing the crioulo breed, Dr. Emilio Solanet.

In 1987, Jorge Saenz Rosas, owner of the Argentine Estancia Cristiano Muerto, offered his criollo Sufridor to the American Louis Bruhnke and the Russian-French Vladimir Fissenko for a horseback ride from the Beagle Channel in Tierra del Fuego up to the shores of the Arctic Ocean in Deadhorse, Alaska. After traveling for five and a half years, the ride was accomplished in the summer of 1993. Having made the entire journey, the Criollo Sufridor is likely the horse that has traveled the furthest in a single direction. The ride was chronicled in the book Sufridor, Emece (2000), written by Louis Bruhnke.
