Wolves as pets and working animals
Some wildlife centers housing captive wolves prohibit handlers from entering wolf enclosures if they happen to have a cold or other vulnerability which the wolves can detect. Captive wolves are generally shy and avoid eye contact with humans other than their owner, as well as not listening to any commands made by any other humans. They usually vacate rooms or hide when a new person enters the establishment. Even seemingly friendly wolves need to be treated with caution, as captive wolves tend to view and treat people as other wolves, and will thus bite or dominate people in the same situation in which they would other wolves. Ordinary pet food is inadequate, as an adult wolf needs 1–2.5 kg (2–5 lbs) of meat daily along with bones, skin and fur to meet its nutritional requirements. Wolves may defend their food against people, and react violently to people trying to remove it. The exercise needs of a wolf exceed the average dog's demand. Because of this, captive wolves typically do not cope well in urban areas. Due to their talent at observational learning, adult captive wolves can quickly work out how to escape confinement, and require constant reinforcement by caretakers or owners, which makes raising wolves difficult for people who raise their pets in an even, rather than subordinate, environment.
Lone wolf (trait)
In the animal kingdom, lone wolves are typically older female wolves driven from the pack, perhaps by the breeding male, or young adults in search of new territory. Many female wolves between the ages of one to four years old leave their family to search for a pack of their own. This has the effect of preventing inbreeding as there is typically only one breeding pair in a wolf pack. Very few wolves will simply remain lone wolves; as such, these lone wolves may be stronger, more aggressive and far more dangerous than the average wolf that is a member of a pack. However, lone wolves have difficulty hunting, as wolves' favorite prey, large ungulates, are troublesome for a single wolf to bring down alone. Instead, lone wolves will generally hunt smaller animals and scavenge carrion.
