The question you are asking is a little unclear. I think you are trying to ask what the average adult size of a German Shepherd is at a particular age. An adult female GSD should reach anywhere from 50-85 pounds depending on breeding lines. Complete growth in large breed dogs is not usually reached until at least 18 months of age, though the majority of their growth has stopped by on year. Based on the photo you have provided and the age, Soska looks to be a very appropriate size at this time.
