The Sapsaree is a nearly extincted Korean native dog whose historic habitat has included much of the Southeastern Korea. The only existing population of Sapsaree consists of 50 dogs living in the small area of Kyung-San Goon in Kyung-Pook Province. Field observations of the population indicated the presence of two distinct morphological phenotypes that are divided into Blue- and Yellow-Sapsaree. A RFLP (Restriction Fragment Length Polymorphism) analysis using pV47-2 probe and Sapsaree DNA indicated the existance of two distinct genetic stocks concordant with the morphological phenotypes.
