They are weaned when they are about seven weeks old but will stay near their mother for another two weeks. Female prairie dogs are very aggressive when they have pups. They will often fight with other females to guard their territory and their pups. Female prairie dogs will invade the burrows of other female prairie dogs and kill any pups they find. The black-tailed prairie dog has one litter a year.
Prairie dogs are very social animals.
They are active in the day. They live in large colonies or towns. A prairie dog town may have thousands of prairie dogs in it. A prairie dog town is separated into smaller neighborhoods and neighborhoods are divided into smaller family groups. A family group or coterie is made up of a male, one to four females and their young.
