Studies on Dochmoides stenocephala (Railliet, 1884), the northern carnivore hookworm.

This work was prompted as the result of a survey done on the parasites of sled dogs in the vicinity of Fort Simpson, N.W.T., during the summer of 1956. The incidence of hookworm infection was found to be 95 per cent in 70 dogs examined. This parasite has been found in dogs from points; all across northern Canada and as far north as Ellesmere Island (Cameron et al. 1940). It has also been reported by Law (1933) from arctic fox taken in the region of Hudson Bay who also mentioned that Hadwen had found it in Alaskan dogs. This suggests that the parasite is particularly well adapted for life in a northern environment
