A sled dog struggles for survival in the Alaskan wild.

The fully CGI model of Buck is a digital scan of a real dog, adopted during production from the Emporia, Kansas animal shelter by director Chris Sanders' wife, Jessica Steele-Sanders. Coincidentally, the dog's name was "Buckley." Buckley is the same kind of mixed breed as Buck is described in Jack London's book: a cross between a St. Bernard and a Scotch collie-type dog (a medium-sized herding dog, similar to a border collie or Australian shepherd). When Jessica Steele-Sanders adopted Buckley as a companion for the Sanders' other dog, Brody, the CG model for Buck at that time was loosely based on a Bernese mountain dog -- however, when the producers saw Buckley and learned that he was the same sort of mixed breed as the dog in the book, it was decided that Buck in the film would be changed to a digital scan of Buckley.
