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
Wolves are often infested with a variety of arthropod exoparasites, including fleas, ticks, lice, and mites. The most harmful to wolves, particularly pups, is "Sarcoptes scabiei" (or mange mite), though they rarely develop full blown mange, unlike foxes. Lice, such as "Trichodectes canis", may cause sickness in wolves, but rarely death. Ticks of the genus "Ixodes" can infect wolves with Lyme disease and Rocky Mountain spotted fever. The tick "Dermacentor pictus" also infests wolves. Other ectoparasites include biting lice, sucking lice and the fleas "Pulex irritans" and "Ctenocephalides canis".
