We have many nicknames for our boys. Bruiser Ballard Scharder : Boo, Boo-boo, Buddy, Tuts, Tutty, Tut-tut(don't ask me how we got to these weird nicknames), Big Boy, Little Man. Marcus Aurelius: Marky-mark, Monkey, Shorty, and Little Boy (but he is still a puppy so that list might grow). As many different nicknames we have for them, they answer to any or all of them.
