She's still really young but she looks yorkie to me. With that said, her colors will change as she gets older so she might look more "yorkie" later on. BUT, please keep in mind that even "full yorkies" might not look like a standard yorkie. Many members here have yorkies that are plus size, floppy ears, hair color variation, etc...
If you're really that curious, you can get a DNA test one. I think it starts around $50? |
