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.
