Here is a picture of my Murfee...I have others but this is my male. He does have 2 ears but he doesn't hold them both up most of the time.
Some have more white on their backs but all of them should have a tri-colored head, 4 white legs, white chin and under belly and white tail tip. Some of them turn steel blue and light gold like the Yorkie but some keep their dark colors...one of my females and one of her puppies are steel blue/light tan/white but my others are all dark.
