Just had this situation a few months ago, some tiny black lab/doberman puppy showed up scratching our front door at 11:30pm one night. We already had a dog I named though so my wife ixnayed all my suggestions:
Pistol (cause I answered the door with one just in case)
Moses (baby showing up on the door...)
Small block
Turbo
Jet
Kit and or Hoff
Ladron (spanish for thief)
Burglar
Ended up getting stuck with Lucky. Other dog's name is Kirsche, which is German for Cherry which is my wife's maiden name, I scored points with that idea.
