I would have guessed Pom and Corgi, or Corgi and Cocker, or Corgi and Pek, but I wouldn't have guessed Chihuahua because of her size...so I was WAY off! lol If you haven't guessed Corgi was my first thought...also, what about Eskimo (toy or minature) or Spitz (toy or minature) to account for the tail??
