Welcome to YT!!!
Coco is soooo adorable!!! And I love her colors!!!!
When you are mixing two different breeds like yorkies and poodles, the puppies can come out to be a wide range of different colors, you are never guaranteed what the pups are going to look like until they are born. I have seen just about every color on yorkiepoos.
My yorkiepoo has alot of chocolate coloring on her, you can't see it in any of her pictures though. For whatever reason that your Coco is chocolate, she is so pretty and her colors are gorgeous as well.
