What a nightmare, Charlie Brown!

What a nightmare, Charlie Brown! is one of my favorites on the series because portrays a snoopy closer to what he really is: a dog
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 and coming to the conclusion Snoopy is "an overly civilized, underly 'dogified' dog". After making a large dinner of three pizzas- all of which he eats himself, Snoopy goes to bed on his doghouse and promptly has a nightmare in which he is a sled dog in Alaska, presumably during the Yukon Gold Rush.
At first Snoopy is cruelly mistreated by his owner and his fellow dogs, being run ragged and then denied any food. One scene which breaks the snow scenes is where the sledmaster stops at a honky tonk, and a hungry Snoopy sneaks inside to snatch a sandwich sitting near a piano where he starts playing. He then finds himself onstage with a painted backdrop of Paris and is cheered for his dancing, except when the music changes and Snoopy impersonates a can can dancer, to which the men riot. Snoopy is thrown out of the bar and is back with the sled dogs.
Unable to take anymore, Snoopy realizes that he must adapt to his "new life" in order to survive, so he changes himself into a real sled dog, and challenges the lead dog to a fight, which Snoopy wins. Ultimately Snoopy becomes the "Alpha Male" of the sled dog pack and leads his owner over an ice-covered lake when the ice cracks and causes all the sled dogs and the owner to be swallowed into the water. Snoopy finds himself being pulled into the hole. As he sinks screaming for his life, Snoopy wakes up and is relieved that he was just having a nightmare.
Snoopy then wakes Charlie Brown and recounts his nightmare in pantomime, to which Charlie Brown allows Snoopy to spend the night inside with him, but not before Snoopy helps himself to a large dish of ice cream, reminding himself his Arctic experience was indeed just a nightmare.
