Above) Randy Henderson is ruled by Mable the Wonderdog much more than he owns her. She has the "tongue thrust" common among chihuahuas; it's always sticking out just a little.
Her mother was an abandoned chihuahua. By the looks, the father would seem to have been a German shepherd. So the appearance overall is of a chihuahua, but the color is that of a shepherd -- and Mabel's a big, very beautiful thirty-pound dog!
Below) Half chihuahua, and half "nobody knows who the dad was," this puppy might be half bull terrier. Looks like she's ready to jump on your face with love.
