she sounds and looks like she has leather ears...Mei Ling had it but I am happy to say that finally her hair is beginning to grow back....it was driving me nuts! Clean it with rubbing alcohol and apply the lotrimin cream daily...here is a link to Terri's website that describe the care of Winter ears aka Leather ears...
Alex's Yorkie Care Frequently Asked Questions. Page 3.
also the first attached pictures is of Mei Ling when we were battling the Winter ears...and the 2nd is the most recent and you can see the hair fuzz coming back in...hehe
