Wolf packs are established according to a strict hierarchy, with a dominant alpha male at the top and alpha female not far behind. Usually this male and female are the only animals of the pack to breed. Packs consist of between five and ten animals – usually offspring from several years. All of a pack’s adults help to care for young pups by bringing them food and watching them while others hunt.

Wolves live and hunt in packs. They are known to roam large distances, perhaps 20 km in a single day. Wolf packs in the far north often travel hundreds of km each year and this is due to them following migrating herds.
