However, you ought to learn that female German shepherds have four stages in their heat cycles. These heat cycles are Proestrus, estrus, metestrus, and anestrus.


Proestrus is the initial stage when your dog is in heat. It’s during this stage that you can note slight va*inal bleeding and vul*a swelling.

During this stage, the female German shepherd is reluctant to mate with a male stud. On average, this heat stage last for nine days.
