A group of wild dogs or canids that live together and carry out the activities of subsistence in this way is known as a pack. The pack has a marked hierarchical structure that all the members that compose it must respect, meaning not doing so will be expelled or eliminated from the group. The pack is considered wild because it cannot coexist harmoniously with the human being, despite the fact that in many cities, due to animal abandonment and poverty, groups of violent and wild dogs abound.
The pack can be made up of several specimens of the animal in question. Normally, the term pack is applied only to groups of dogs such as dogs, wolves, jackals and others. Curiously, the fox (despite being a dog) does not form packs since it lives alone or in pairs. The packs basically serve to facilitate the different subsistence tasks of the group, especially with regard to obtaining food. Needless to say, by acting together the dogs achieve greater effectiveness in this task, being able to hunt more frequently, they can also get larger animals that otherwise could not be hunted.
As is to be expected in any type of group, the packs are ordered through deep and marked hierarchies, which can also happen in the case of some felines such as the lion. The packs are usually led by a male (known as an alpha male), the one who guides the pack and who can establish his leadership through physical strength over the rest.
Depending on the animal in question, the pack will have different characteristics, very particular to each case. This has to do with elements such as the formation of pairs within the herd, the duration of its members in the group (if it is for life, or until a certain moment of the biological cycle), the functions that each member fulfills within it, etc.
