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.
Irish wolfhound
The Wolfhound of today is far from the one that struck fear into the hearts of the Ancient Romans. Irish Wolfhounds are often favored for their loyalty, affection, patience and devotion. Although at some points in history they have been used as watchdogs, unlike some breeds, the Irish Wolfhound is usually unreliable in this role as they are often friendly toward strangers, although their size can be a natural deterrent. However, when protection is required this dog is never found wanting. When they or their family are in any perceived danger they display a fearless nature. Author and Irish Wolfhound breeder Linda Glover believes the dogs' close affinity with humans makes them acutely aware and sensitive to ill will or malicious intentions leading to their excelling as a guardian rather than guard dog.
