Thanks everyone! When we got him, the shelter guessed Pomeranian/Sheltie. Our veterinary technician thought Chihuahua mix, and we think Papillon/Pomeranian. But we really don't know.
BEautiful photos. My guess would be pap mix as well. THe cat ones where you brought out the eye color and blanched all color but the tongue are way cool.
SAlly is a doll. I have always been a sucker for white eyelashes.
