When a boy leaves his hat behind, the family dog knows what to do. This wordless picturebook uses the format of an adventure story to depict one dog returning his owner’s hat to him. The dog manages to find the Tube station, board a train, push through the busy tunnel, and chase up the escalators to return the hat to his owner. The innocence of the dog to his surroundings mirrors the early city experiences of children everywhere. The picturebook creates the opportunity to consider different types of public transport, their role in society, and their representation in other works of children’s literature. The sequel to this text is Dog on a Digger.
