 Some tribes used the dog as a draft animal to pull small travois (or sleighs) to help move from place to place; however, by the 18th century, many Southern Plains tribes adopted the horse culture and became nomadic.The tipi, an animal hide lodge, was used by Plains Indians as a dwelling because they were portable and could be reconstructed quickly when the tribe settled in a new area for hunting or ceremonies.Historically, the Arapaho had assisted the Cheyenne and Lakota people in driving the Kiowa and Comanche south from the Northern Plains, their hunting area ranged from Montana to Texas.
