How Ace Became Batman’s Dog (Rebirth)
That was oddly touching. I can’t unsee Batman doing baby voices on a dog. Also, Bruce Wayne just can’t help himself donning everything that comes into his care with a mask and cape huh? Bat-hound indeed.
I like the idea of Batman owning a dog that used to belong to the Joker. Seems fitting in a way.
