A jennet or Spanish jennet was a small Spanish horse.[1] It was noted for a smooth naturally ambling gait, compact and well-muscled build, and a good disposition. The jennet was an ideal light riding horse, and as such spread across Europe and provided some of the foundation bloodstock for several horse breeds in the Americas.

The Andalusian, also known as the Pure Spanish Horse or PRE (pura raza española[1]), is a horse breed from the Iberian Peninsula, where its ancestors have lived for thousands of years. The Andalusian has been recognized as a distinct breed since the 15th century, and its conformation has changed very little over the centuries. Throughout its history, it has been known for its prowess as a war horse, and was prized by the nobility. The breed was used as a tool of diplomacy by the Spanish government, and kings across Europe rode and owned Spanish horses. 

Strongly built, and compact yet elegant, Andalusians have long, thick manes and tails. Their most common coat color is gray, although they can be found in many other colors. They are known for their intelligence, sensitivity and docility.

The Barb or Berber horse (Berber: Ayis Amaziɣ, ⴰⵢⵢⵙ ⴰⵎⴰⵣⵉⴳ; Arabic: حصان بربري) is a North African breed of riding horse with great hardiness and stamina. It is closely associated with the Berber or Amazigh peoples of the Maghreb. It has influenced a number of modern breeds, including many in northern and western Africa.

The Barb is now bred primarily in Morocco, Algeria, Spain and southern France. Due to difficult economic times in North Africa, the number of purebred Barbs is decreasing. The World Organization of the Barb Horse, founded in Algeria in 1987, was formed to promote and preserve the breed. In 2014, the FEI recognized the Barb horse as their Horse of Honor at the World Equestrian Games in Normand

The mustang is a free-roaming horse of the Western United States, descended from horses brought to the Americas by the Spanish. Mustangs are often referred to as wild horses, but because they are descended from once-domesticated animals, they are actually feral horses. The original mustangs were Colonial Spanish horses, but many other breeds and types of horses contributed to the modern mustang, now resulting in varying phenotypes. Some free-roaming horses are relatively unchanged from the original Spanish stock, most strongly represented in the most isolated populations.
