In this study, we analyzed the microsatellite DNA poly-morphisms for pedigree verification in Kyungju dog (Dongkyung-i) which is one of the Korean breed dogs. A total of 51 Dongkyung-i samples were genotyped using 8 microsatellite markers. The number of alleles observed at single locus ranged from 4 to 12, with average number of alleles per locus of 8.5. The expected heterozygosity and polymorphic information contents (PIC) values of the 8 microsatellite loci were $0.6162{\sim}0.8746$ (mean 0.7587) and $0.5461{\sim}0.8512$ (mean 0.7167), respectively. Of the 8 markers, PEZ3, PEZ6, PEZ12 and FHC2054 loci had relatively high PIC values (>0.7) in Dongkyung-i. Pedigree verification of Dongkyung-i was analyzed based on alleles observed. The results of the parentage testing were noted significant differences compared with breeders. These results show basic information of conservation and research in Dongkyung-i, and further studies of genetic pedigree in Dongkyung-i will be needed.

Until now, there are no scientific studies for Dongkyung-i(DKI) dog, which is recently called as Deng-Kyun. This study is aimed to investigate the characteristics of DKI. According to visiting studies, DKI is an active, live and muscular dog. The dog is willing to announce the approach of strangers friendly. As the results of morphological studies, DKI is medium sized and the average weight is 22.6 kg. Its coat has mainly yellowish brown color and short hair. Morphologically, the dog showed vestigial tail and muscular and sturdy pelvic limbs. As the results of radiological studies, DKI is characterized as the absence of coccygeal vertebrae or the coccygeal agenesis. We concluded that DKI may be a Korean native canine breed characterized as short or non-tail dog. Also, we suggested that this characteristic dog is valuable to develop as a Korean native breed.
