This study aims to construct the basic data of ground-scratching behaviors of Korean native dog, Jindo-Gae (Canis lupus familiaris) and to estimate the frequency of ground-scratching, especially natural and artificial environments. Ground-scratching rate of female and male dogs are 1 : 40.25. Ground-scratching after feacal-marking rate by male is 17.9 times higher than female. Ground-scratching behavior of jindo-Gae thought to a multiple sign combining visual and chemical elements. Native dogs thought to a missing link in dog domestication, thus behavioral comparisons between wolves and Korean native dogs are needed.
