Mingo's mom says: Mingo is 18 months but she is a little girl. She was named after a Chihuahua that my grandmother had in the 1950s. I had never known she had a Chihuahua until I got my first and then I learned all about Mingo the first. Mingo does have a male namesake but she is definitely a little girl. She is a long-haired chocolate Chihuahua and tips the scale at just over six pounds.
