Their undersides are buff and their tales are black tipped. Tail length is around 4 inches, but it varies from individual to individual. Prairie dogs have sharp incisors used to clip their food and strong hind legs so that the prairie dog is able to stand upright.
Prairie dogs live in coteries, which consist of several towns.
These towns are a complex series of underground tunnels which keep the prairie dog safe from fires and predators. Among the list of predators are hawks, various snakes, the now extinct black footed ferret, and man. Prairie dogs are remarkably sociable animals. Kissing, hugging, or touching noses are common greetings among the individuals of the coterie. Relationships within the coterie vary seasonally.
