In Sled Dogs, readers will meet many dogs that compete alongside their handlers, or mushers, in popular winter races across the frozen terrain. Children will learn the history of sled dogs as they meet Balto, a heroic working dog that raced 50 miles through blizzards to transport medicine for sick patients in Nome, Alaska, in 1925. Exciting narratives and great photos grab readers' attention in these stories of man and dog working together.
