Mustangs are known for being wild in the United States west. They are found in all colors, and usually stand from 13 to 16 hands.
10,000 years ago, Mustangs roamed the Americas. Then they vanished until the Spanish arrived with their Barb horses. Lots of Indidan Tribes loved the Mustang, so they brought them further into America. Then the settlers came and the only herds were of escaped or abandoned horses. The Wild Free Roaming Horse and Burro act was passed in 1971 protecting Mustangs from slaughter. The government established Herd Managment areas and the Mustangs there are for adoption.
The Mustangs are found in all colors, even spotted patterns like the Appaloosa.
