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.
Wolf
Globally, gray wolf diet is predominantly composed of large () and medium-sized () wild ungulates, with local population variations due to the mix of wild ungulates, smaller prey and domestic species consumed. All terrestrial mammalian social predators feed predominantly on terrestrial herbivorous mammals that have a body mass similar to that of the combined mass of the social group members. The gray wolf generally specializes in preying on the vulnerable individuals of large prey, with pack of timber wolves capable of bringing down a moose. Digestion only takes a few hours, thus wolves can feed several times in one day, making quick use of large quantities of meat.
