Mx (pronounced “mix”) is the one I hear most common.
I’m also partial to Mage (or Mg.). It’s a shortening of the Latin word “magister,” which means “chief, head, director, teacher.” Magister is the root word from which we get “mister” and “mistress”
Such a gorgeous doggo!! My heeler had nearly the exact same facial markings 😭 I had 14 years with that good boy.
