Looks like a Chihuahua to me. There are variations, of course within a breed. Some are bred closer to the AKC standard, some not so much. But from what I can tell in the photo...her head, her features, she looks very Chihuahua. The important thing is she's adorable and hopefully, this breeder she came from did some genetic health testing on the parents and that she breeds for good temperaments. That is what is most important for me. She sure is a cutie.
