Current Review of Artificial Insemination in Dogs.

Artificial insemination is the collection of semen from the male and the subsequent insertion of the collected semen into the female. Artificial insemination may be requested for several reasons, including inability to achieve a mating or due to the use of fresh chilled or frozen semen. A good understanding of the cycle of the bitch is imperative for maximizing pregnancy rates, as poor timing of insemination is the most common cause of subfertility in the bitch. Insemination techniques commonly undertaken in the bitch include vaginal insemination, surgical intrauterine insemination, and transcervical insemination.
