I would guess she might have some Min Pin in her. Take a look through these Min Pins for adoption. Some of them have a close resemblance to yours.
She alot prettier than a plain ole chihuahua. Try googling Chizer. Thats a Chihuahua/Mini Schnauzer mix. Read up on the "designer breed" and see if any of those doggie faces resemble your little girl. I just want to point out that when her ears are down they look like schnauzer ears. Attched is a pix of my boy Divo.
With a delightful face and beautiful big eyes like that will it really matter what "mix-breed" she is. From the front view photo her front legs appear to be "east-west", this is absolutely nothing to worry about just the way they are born ask your Veterinarian. Love her for who she is and had the good fortune to "fall on her paws" to have you as her "family".
