She looks like a tiny GSD!
My brother adopted a German Shepherd/Border Collie named Nahla a few months back. She's about 3 years old and is as big as she'll get.
She looks like a 25lb black German Shepherd to me (aside from the white on her toes and the tiny white patch on her chest).
This is her, "THERE IS A CAR PULLING UP, I WONDER WHO'S INSIDE!" face, which shows off her big ears pretty well.
I swear, if they could find a way to guarantee that that cross always looked like tiny German Shepherds...
