tIt is confusing I know but heres my explanation. A silky terrier is a separate breed that resembles a yorkie but is usually a little bigger than a yorkie. A yorkie can have 3 different kinds of coat texture: silky, cotton coated and modifieed which is a mixture of the 2. So a yorkie can have a silky coat and it is the prefered coat according to the yorkie standard. I hope that helps you |
