Artificial insemination with frozen canine semen using vaginal endoscope was performed in a two years old Golden Retriever to investigate the feasibility of this technique. The bitch was in her second estrus. Blood progesterone concentration was evaluated every two days to decide the timing of insemination since vaginal bleeding was observed. Insemination was performed twice in 48 hours interval on the fourth and sixth posterior to LH surge, respectively. The volume of frozen semen injected was 1.5 ml $(1{\times}10^{8}$ sperms/1ml of semen). The bitch was pregnant and she whelped a female pup on sixty one days after first insemination.
