The Leonberger is a giant dog breed, whose name derives from the city of Leonberg in Baden-Württemberg, Germany. According to legend, the Leonberger was ostensibly bred as a 'symbolic dog' that would mimic the lion in the town coat of arms. It is in the Working Group for dog shows such as Crufts, but not at the World Dog Show. Three Leonberger dogs (one was a female, and two males) played the main character Buck in The Call of the Wild: Dog of the Yukon (1997), a Canadian rendition of Jack London's The Call of the Wild which stars Rutger Hauer as John Thornton and is narrated by Richard Dreyfuss. The breed chosen in this movie was not the one identified as Buck in the novel.
