The star of the enormously popular comic book series “The Adventures of Tintin,” by Hergé (Belgian artist Georges Rémi), is a young reporter named Tintin. But it’s Tintin’s constant companion, the spunky Wire Fox Terrier Snowy, who sparks the stories. Snowy provides comic relief, rescues Tintin from danger, butts into everyone’s business and noses out important clues, often accidentally.
