A breed developed in the 18th century by the Nez Percé tribe of Native Americans and descended from the horses taken to the New World by the Spanish conquistadores in the 16 th century, the Appaloosa is famous for his colorful, spotted coat and striped hooves. Adopted as the state horse of Idaho in 1975, the Appaloosa was once called a “Palouse horse” after the Palouse River which is located in the US states of Idaho and Washington where the breed originated. The horse is favoured as an all around, compact saddle horse with powerful quarters and tractable disposition.
