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.
Wolf
Being the most abundant carnivores, free-ranging dogs have the greatest potential to compete with wolves. A review of the studies in the competitive effects of dogs on sympatric carnivores did not mention any research on competition between dogs and wolves. Competition would favor the wolf, which is known to kill dogs, however wolves tend to live in pairs or in small packs in areas where they are highly persecuted, giving them a disadvantage facing large groups of dogs.
