Abstract: The present disclosure relates to an SNP marker set for dog identification and a dog identification method using the same. The present disclosure can accurately and easily readably identify individual dogs through the SNP markers on the gene and combinations of the SNPs based on the simple results of AA/AB/BB (Homozygote/Heterozygote/Homo mutant) by using 381 single nucleotide polymorphisms (SNPs) on the gene, thereby proving to be useful for animal individual identification.
