For most natural matings or artificial inseminations with fresh semen, breeding should begin 2-3 days after the LH surge , and continue every 2 or 3 days until The goal of breeding is to inseminate the bitch four days before ovulation and then every two days until the final insemination at two days after ovulation. The https:// ensures that you are connecting to the Every 2 to 3 days, blood samples should be evaluated for progesterone levels and insemination occurs.

In the past 2 to 3 decades, several strategies were developed to escape the subjectivity in the semen evaluation, related to the experience and skills of the observer, the method of specimen preparation, staining technique and number of cells evaluated, and wich is particularly important when the fertility potential of preserved sperm cells has to be ascertain. Besides regulations on performing AI to a bitch, attention must be paid to issues concerning the semen collection and use.
