All three of my babies shine blue and green.
I know Eva has a silky coat, but her puppy coat seemed sparse
compared to her litter mate. She is changing though, and is now growing in a thicker coat that started on her legs. I have no idea what her saddle color will be, right now it is black as night, but she is breaking a light gold/bleached blond on her head.

(Eva is 6 months)
My little Doc's coat shines and never tangles, but unlike Eva it is thick AND silky. He has not started breaking, he is still black and tan. (Doc is 15 weeks)
Bella has a thicker coat too, her saddle is silky and soft, but she gets knotty on her legs and underbelly if I don't brush her everyday. Probably from Doc chewing on her legs.

Bella is breaking that sootie or dark gray color on her head. (Bella is 25 weeks)
Yorkies are the most puzzling breed I've ever had, as far as coat color, and everyone I know is waiting (with great anticipation) for the next piece of the puzzle, the next clue ... it's like watching an artist paint a murial, with each stroke of the brush we try to get a glimpse so as to spark our imaginations and yet we wait with baited breath for the day we can stand, with excitement, to view the breeders work, the finished masterpiece, our beautiful Yorkies.
It's like the never ending GIFT.
