I feel like an idiot, but I bought a Yorkie 5 years ago, and somebody just told me he is a Silkie!! Either way, he is my love, but I would like to know. he vet or groomer has never mentioned he is a Silkie

Can somebody give their opinion please? His photo is attached. And another thing. He is big, like almost 15 pounds. The people we bought him from said he would be 6 pounds!!!
