Innocent Bystanders appeared in several episodes of Dog City. A group of young, often whimpering puppies, usually in a sandbox or playpen, the Innocent Bystanders frequently end up in the way during Ace Hart's preliminary battles with Baron Von Rottweiler. Miraculously, they avoid harm each time. In the first episode "The Big Squeak," they show their gratitude by clinging to Ace. Rosie O'Gravy is touched by it, but Ace points out it won't last long; soon their little muscles will give out, and they'll fall right off.
