It is important to note that female German Shepherds can only get pregnant during a very specific time in their estrus cycle, which lasts about 1-3 days. This is known as the "fertile window" and it occurs about 10-14 days after the first day of bleeding.
To ensure that you breed your female German Shepherd at the right time, it is important to monitor her for signs of estrus, such as:
* Swollen and reddened vulva
* Increased urination
* More frequent licking of the vulva
* Flirting with male dogs
* Increased activity and restlessness
If you notice any of these signs, it is important to contact your veterinarian to confirm that your dog is in estrus and to determine the best time to breed her.
