If she is changing color & had her rabies shot a little while ago, I'm assuming she's around 5 months old, like my puppy. She is probably just blowing her puppy coat and starting to get her adult coat. I've had yorkies before and never knew they did this, but sure enough, my puppy has lost alot of her puppy hair and has new hair growth coming in. She's shed alot of the black on her head & has tiny tan growth about 1/4 inch long coming in. She's also lost black hair on her ears & has new tan growth there too.
