One winter day, Charlie Brown is trying to pretend to be a musher with Snoopy, but the dog has other ideas and gets Charlie Brown to pull while he has fun riding in the sled. When night comes and they are comfortably indoors, Charlie Brown is indignant that Snoopy is adjusting too well to home life, reminding Snoopy of facts that Arctic dogs are only fed once a day, their meals largely consisting of cold meat and raw fish (to which Snoopy blanches and gives a look of "it's too bad to be them") and coming to the conclusion that Snoopy is "an overly civilized, underly 'dogified' dog". Snoopy makes a sumptuous dinner of five pizzas and a milkshake, to which Charlie Brown retorts he hopes Snoopy can digest all that food. Snoopy then falls asleep atop his doghouse, but when he wakes up he finds himself in a polar region, to which he is made a sled dog of the Iditarod Trail Sled Dog Race in Alaska, presumably during the Klondike Gold Rush or the 1925 serum run to Nome.
