I can't positively answer your question however, our pup is 16 weeks and at first the left ear was up, then they were both up, then the left ear dropped and the right ear stayed up. Now once in a while they are both up, then both down. I personally think it is what it is and eventually they will both go up. Mom and Dad had both ears up and I trust that his will both be up in the end.
