To maximize fertility when breeding dogs, it is necessary to estimate the female's day of ovulation. Because of this, a luteinizing hormone (LH) may be given to female dogs in order to control ovulation and regulate the bitch’s cycle, allowing breeding to be timed accordingly. The period of maximum fertility occurs approximately five to six days after the LH peaks. In this time, multiple breedings may be done by inseminating the bitch up to three times per week after progesterone levels rise. Frozen semen, though less likely to work than fresh chilled semen, may be used to inseminate the bitch – a single insemination five or six days after LH hormones peak is common. It is important to time insemination based on progesterone levels in order to improve chances of conception.
Living and Management
After initial fertility-maximizing measures have been taken, a follow up pregnancy examination can be done to determine the success of the procedure. This can be done via vaginal specimens. The gestation period for dogs lasts approximately 63 days from ovulation.
