This study was performed to induce the estrus in 9 anestrus Shih-tzu bitches by intramuscular injection of pregnant mare serum gonadotrophin (PMSG) 50IU/kg for 10 consecutive days and by intravenous injection of human chorionic gonadotrophin (hCG) 1,000IU/Head on Day 10. The day when the first injection of PMSG was counted as Day 0 of experiment. All of the bitches were monitored by vaginal discharges, displays the perineal region, vaginal swelling and male acceptances. The 9 bitches (100%) showed vaginal discharges and vaginal swelling, and were mated. The 5 bitches out of 9 bitches were pregnant (55.6%) and 4 bitches were non-pregnant (44.4%). The 3 bitches out of 5 pregnant bitches were spontaneously delivered (33.3%) and litter size were $1.66{\pm}1.15\;(1{\sim}3\;pups)$ pups. The 2 bitches were diagnosed as early embryonic death on days 38 and 41 after first injection of PMSG. These results indicated that rates of estrus induction, pregnancy and delivery were 100%, 55.6% and 33.3%, respectively, using PMSG and hCG.
