Often portrayed as tricksters and con artists in popular folklore, wolves have a family life that is more loyal and pious than most human relationships. Normally, packs consist of a male, a female and their offspring, essentially making wolf packs akin to a nuclear family. The older offspring even help take care of their younger siblings.

Occasionally, a lone wolf will be welcomed into a pack. A pack can range from just three or four wolves to as many as 20, depending on the food supply in the area.
