Shiro (Whitey in the Funimation dub) is a white, fluffy dog belonging to the Nohara family. While a beloved member of the family, he is the subject of neglect thanks to his owner's forgetfulness and short attention-span. He is a highly intelligent dog, often presenting logic and intellect that surpasses his human owners. As his meals from the Noharas are at best inconsistent, he has developed a talent for foraging, though other times he has to eat Misae's failed culinary experiments. Endowed with oddly human-like attributes, he is very responsible and painstakingly careful. He takes care of his owners diligently, though often they do not realize his help or understand what he is trying to show them. His doghouse also often ends up becoming a place for Shin-chan to hide himself or something he doesn't want his family to find.
