Artificial Insemination is usually carried out with good quality fresh semen drawn and inserted into the cranial part of the vagina via a catheter immediately after semen is collected from the male. Using this method, the semen is deposited directly in front of the cervix or as close to the cervix as possible.
If the semen quality is not as good as required, a positive of using this method means it can be tested prior to insemination. A semen extender can be added to improve the quality and performance of the semen, thus improving the chances of producing a litter.
In some circumstances, a natural mating can be difficult to achieve if the bitch / dog is inexperienced or uncomfortable, they may have trouble mating even if physiologically the bitch is ready to mate. Any significant size mismatch between the two, or should either party be dog aggressive, this can be over come using the AI method of insemination.
