As prairie dogs often live in areas with environmental hazards such as hail, blizzards and floods as well as drought and prairie fires, caves offer an important protection for them. Caves can help prairie dogs to control body temperature (thermoregulation) 5-10 ° C in winter and 15-25 ° C in summer. Burrows are 5.10 meters (16-33 feet) long and 2.3 meters (10.06 feet) underground. More research is known as the rim of the crater, which can be up to 1 m.

When hiding from predators, prairie dogs use less deep chambers tend to be usually less than a meter below the surface, children's rooms 2-3 meters below the surface. Very social, prairie dogs live in large colonies or "towns" collections of prairie dog families that can span hundreds of acres. Family groups of prairie dogs are the basic unit of society.

The females remain in their natal groups for life and therefore the source of stability in the groups of men leave their natal groups when they encounter another group of family, uphold and carry some families have more breeding females of a grown man can control in order to have more than one adult male in his creation. Two or three groups of females are controlled by a male. However, among these groups of women, no friends. The area occupied prairie dog average from 0.05 to 1.01 acres. The male inhabitants of a territory which defends and agonistic behavior between two men from different families seem to defend their territories. the fight against prairie dogs bite, kick and ram the other.
