I couldn't say. I am aware, though, that chihuahuas come in lots of colors, and in two different coat lengths.
Irish Wolfhounds are up there, but they don't range as much in colors or coat length like chihuahuas do.
Chihuahua dogs are so cool, the Taco Bell dog was hilarious! Those are the smallest of the dog breeds. Did you know there's a state in Mexico called Chihuahua? No, that's cool! They re pretty tiny. What is the largest breed?
Chihuahuas come in a wide variety of colors, and two coat lengths.
