She's a "teapot" Yorkie I have a 9 almost 10 pound Yorkie here he came to me weighing over 11 pounds but have talked to others on here who have much larger Yorkies that are proven purebred...wavy hair also happens sometimes...dull coat huh she looks decent in the pic maybe she has a super conditioned cottony coat though...
I used and trust this company to identify my rescue as a Schnorkie (Yorkie mini Schnauzie hybrid) my vet uses them and they are the most comprehensive for accuracy...but either or your dog is gorgeous and looks Yorkie to me.
