He looks very Mixed to me......if i seen this dog in a room with other dogs i would not say to myself that is a yorkie......however he is very very cute.......did you see the parents when you got him???.....i dont even know why i asked that question......my friend bought a yorkie from this couple who passed off someone else's dogs as the puppy's mom and dad......the dog grew up looking nothing like what she expected!!!!!........your dog has some yorkie in him but as far as 100% purebred......doesn't look like it at all |
