This study aims to construct the basic data of faecal-marking behaviors of Korean native dog breed, Jindo-Gae (Canis lupus familiaris) under the influence of spay and neuter and to estimate the frequency of faecal-marking, especially natural and artificial environments. Faecal-marking rate of female and male dogs are 3.43 : 1. Faecal-marking after urination by male is 13 times higher than female. Ground-scratching after feacal-marking by male is 24 times higher than female. Faecal-marking by jindo-Gae thought to a multiple sign combining visual and chemical elements and their faecal-marking postures are similar. Native dogs shows that a missing link in dog domestication, thus behavioral comparisons between wolves and Korean native dogs are needed.

This stuy aims to construct the basic data of urine-marking behaviors of Korean native dog breed, Jindo-Gae (Canis lupus familiaris) under the influence of spay and neuter and to estimate the frequency of urine-marking, especially natural and artificial environments. Most urination by male were RLU(87.3%)and by female were SQ(66.3%). Urine-marking by jindo-Gae thought to a multiple sign combining visual and chemical elements, also seem to sex dimorphism behavior. Native dogs shows that a missing link in dog domestication,thus behavioral comparisons between wolves and Korean native dogs are needed.
