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
Gray wolves typically dominate other canid species in areas where they both occur. In North America, incidents of gray wolves killing coyotes are common, particularly in winter, when coyotes feed on wolf kills. Wolves may attack coyote den sites, digging out and killing their pups, though rarely eating them. There are no records of coyotes killing wolves, though coyotes may chase wolves if they outnumber them. Near identical interactions have been observed in Eurasia between gray wolves and golden jackals, with the latter's numbers being comparatively small in areas with high wolf densities. Gray wolves are the most important predator of raccoon dogs, killing large numbers of them in the spring and summer periods. Wolves also kill red, arctic and corsac foxes, usually in disputes over carcasses, sometimes eating them. In Asia, they may compete with dholes, though there is at least one record of a lone wolf associating with a pair of dholes in Debrigarh Wildlife Sanctuary.
