Abstract. This paper presents the results of paleoparasitological studies of canine paleofeces from the Early Holocene site on Zhokhov Island, located on the New Siberian Islands in the Arctic East Siberia and dated to approximately 9200–8600 years ago. The aims of the study were: 1) to identify parasitic diseases in dogs through archaeoparasitological analysis of their excrement; 2) to determine possible routes of infection; 3) to use the obtained data to reconstruct the economic activities, domestic practices, and diet of the ancient population that left the Zhokhov Island site. In search of evidence, 34 samples of fossil dog feces yielded by the excavations at the Zhokhov site in 2002 and 2003 were analyzed. Eggs of tapeworms of the genus Dibothriocephalus, presumably Dibothriocephalus latus, were found in 91,18 % of the samples, and eggs of cestodes of the family Taeniidae were identified in 32,35 % of the samples. The high level of diphyllobothriasis infection in dogs indicates the significant role of fishing in the economic activities of the inhabitants of the Zhokhov site, despite the small number of direct archaeological evidence of this activity. The presence of eggs of the family Taeniidae indicates that dogs were fed reindeer meat. The results of the study allowed us to reconstruct the diet of dogs and, indirectly, of humans, assess the risk of zoonotic infections, and determine the parasitic burden on the Early Holocene population of the Arctic zone of East Siberia.

Keywords: dogs, Arctic, Early Holocene, permafrost, paleoparasitology, canine paleofeces, dog diet, Dibothriocephalus latus, Taeniidae.
