This study was carried out to investigate the general characteristics such as semen volume, pH, sperm motility and sperm concentration of the semen collected from Korean Jindo dogs by the mothod of Digital manipulation of penis, and the effect of temperature and preservation time on motility of fresh semen. Multiple ejaculates were collected from four male Korean Jindo dogs. The results obtained in this experiment were as follows : 1. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction and the small volume of third fraction from the ejaculate were 3.29ml, 6.30, 96.70% and 1.64times108 cells/ml, respectively. 2. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the first fraction from the ejaculate were 1.16ml, 6.10, 6.67% and 5.07times105cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the second fraction from the ejaculate were 2.30ml, 6.33, 97.66% and 1.92times108cells/ml. Average semen volume per ejaculate, semen pH, sperm motility and sperm concentration of the third fraction from the ejaculate were 3.24ml, 6.51, 93.33% and 3.13times107cells/ml. 3. Motility of fresh semen during preservation were higher at 17^{circ}C than at 5^{circ}C or 36^{circ}C. When preservation temeprature was 17^{circ}C, motility were 95.75% at 1 h, 90.00% at 6 h, 84.25% at 12 h, 68.00% at 18 h, 36.25% at 24 h and 28.75% at 30 h, respectively.
