I have been told several times, by breeders as well as owners of both silkies and yorkies, and even my vet two weeks ago, that my lovely yorkie is really a silky. He looked way different than other yorkie puppies when I first got him, and even now he just looks... different. His hair is shorter and a little coarser than a silk haired yorkie (but not cottony, really) He weighs 13.5 lbs, his hair is really short, and his face is shaped differently. He was sold to me as a pure yorkie, but his breeder was really shady (I was so ignorant when I bought him) Here are pictures of him from when he was a puppy as well as current pictures. I hope they help figure out your baby:

I hope that helps!
