What is an interesting fact about the Appaloosa horse?

The Appaloosa is a breed of spotted horse that originated in the Pacific Northwest of the United States. Their defining characteristic is a speckled coat, which can range from a few random spots to a completely covered coat in an array of colors. Their spots are actually caused by a dominant genetic trait called "leopard complex." This trait produces areas of skin with fewer pigment-producing cells, resulting in the characteristic spots. Appaloosas are known for their intelligence and trainability, making them versatile for a variety of disciplines such as Western pleasure, trail riding, and even racing.
