Ace the Bat-Hound is Batman and Robin's dog, a canine member of the Batman Family. He is a very good boy. He wears a mask to conceal his secret identity as Bruce Wayne's dog Ace. There have been several dogs named Ace, due their short lifespan. In the Prime Earth, another dog named Titus appeared as the second Bat-Hound before Ace was re-introduced.
Ace the Bat-Hound was created by Bill Finger and Lew Sayre Schwartz, first appearing in Batman #92 (1955).
