I have seach threads and this is teething I guess. Tucker is almost five months. He has always have up ears. Two days ago one fell. It is amazing how different he looks. His ears were already shaved. I don't care if they are up or down, I just hope that both ears do the same thing. Does anyone know if Yorkies can grow to be adults and have one ear up and one down? My vet said the laid down ear would most likely go back up. How long does it take to go back up if it is teething? I was just curious about this new look, and I want you to know, that I would still love him if he had no ears
