My in-laws have a Rottweiler/Husky mix, and she had HUGE ears as a puppy (still somewhat now, but not nearly as disproportionate as it used to be). It honestly looked like someone took full, floppy rotty ears and stood them up like a husky's. So they started calling her a "Bat-Eared Rotsky".
I hadn't thought about that in a long time, and your thread reminded me of it. Haha! I also like "Rhodesian Dirtback". For some reason that name just really amuses me.
