Spanish mustangs are a breed of horse that descended from the horses brought to the Americas by Spanish explorers in the 16th century. These horses are known for their hardiness, agility, and adaptability to various environments. They typically have a strong build, with a short back and sturdy legs, making them well-suited for rugged terrains. Over time, Spanish mustangs have developed into a distinct breed, often found in the western United States. They are recognized for their unique colors and patterns, which can vary widely. These horses are also valued for their intelligence and strong bond with humans, making them popular among equestrians.
