Kind of just bumping this for you.
As for the brown spots - were they a "sore" at one point? Often times, yorkie skin will heal "brownish" and then turn normal again later, it's strange. I'd probably take her to the vet again and get a skin scrape to see if it's fungal. The brown spot isn't shaped like a ring is it?
