4fourpaws..... I am not quite sure if I understand the post
It says she is male dog social, does that mean she is not accepting other females?
I hope you find a good home for her, but having worked in rescue for many years, my advice to you is to hang on to dear life to the families who are willing to adopt her already. No they might not be ideal, they might need a bit introduction to a GS and a bit help, but if you already have families who have the heart and desire to adopt her, it sure beats being euthanized.
Can you tell me a bit more about where she is located, and maybe since she already is in a foster home, the parents can accept a bit longer stay until the perfect family comes around
