What Breed is My Puppy?

I adopted this baby from a rescue organization; she was simply labeled "mixed breed". She is approximately 13 weeks old, 16 inches tall at the shoulders and 20 inches long (not including tail). She seems to have a typical Whippet temperament; lays on her bed endlessly then gets up and sprint laps around the yard. However she has such a pretty face that it reminds me of German Shepherd.
