Great to know. A few people had me convinced he was a Mal. Again, not that it mattered because he is quite simply awesome no matter what he is
From my uneducated point of view:
His build does look more Mal like to me in that his hips are not low like a lot of GSD's I see. He is very slender and extremely agile and fast. His build is more slight than many GSD's I've seen too, so that's why I thought that he might be a Mal (in addition to a couple of people telling me that he was).
