The origin of Korean Native dog was studied by investigating the phylogenic relationships of Asian breed dogs. Polymorphic frequencies of 5 blood proteins of the breed, Hb(haemoglobin), Gmo(ganglioside monoxygenase). Es-2(esterase-2). Poa-2(post- albumin-3) and Ptf(pretransferrin) revealed that Sahalin and Eskimo dogs were the closest relatives to Korean native dogs. Polymorphic microsatellite loci analysis of 11 Asian native dogs also attested the same phylogenetic relationship of blood protein. Korean native dogs. Sapsaree. Jindo dog and Chejudo dog, formed a blood group and showed a close relationship with the Eskimo and Sahalin dogs. It was concluded that Korean native dogs were originated from the dogs of Northern part of Far East Asia from which Eskimo dog and Sahalin dog were also originated in the prehistoric age.
