Wolves as pets and working animals
Generally speaking, on the basis of their experience, tame wolves are strictly "one-man dogs". They may be confiding and playful with the man who raised them, or even with his whole family, if fed and cared for by them, but they are suspicious and timid in the presence of strangers. They invariably retain certain reactions of wolf nature, as for instance, an incorrigible desire to kill chickens or other small livestock whenever opportunity arises.
Vancouver Island wolf
The Vancouver Island wolf ("Canis lupus crassodon") is a subspecies of grey wolf, endemic to Vancouver Island, British Columbia, Canada. It is very social with other wolves, and lives in packs of about five to thirty-five. It is very shy, and is rarely seen by humans. Wolves at the Pacific Rim National Park Reserve area have been known to attack and kill unguarded domestic dogs. There are also two Vancouver Island Wolves at the Greater Vancouver Zoo.
