He clearly has GSD in him... but he looks like a mix to me. His ears to do look very floppy, but one ear did stand in one of the pictures, that is a sign of hope. It is possible they will, or maybe they will just come up and have a slight bend towards the top. He looks very very much like a mix to me, so it depends on the other breed(s). He most definitely has GSD in him, though.
