The prairie dog is a kind of squirrel. It has brown fur and a short tail. Prairie dogs eat grasses, leaves, roots, and seeds. Some types of prairie dogs live in big colonies and dig enormous burrows. Members of the colony use different sounds to signal each other about danger. For example, If
wolf approaches, a prairie dog will bark to warn members of the colony. The prairie dogs then go to their burrows. Prairie dogs also have a special
