The domestic donkey is a sturdy mammal of the horse family. People have kept it for over five thousand years for transporting goods and working in agriculture.
The domestic donkey differs from the horse by its long ears, smaller size, and ability to go without water for a long time. It helps transport loads through mountains and deserts where machinery is useless.
