What a Nightmare, Charlie Brown/YMMV


 * Nightmare Fuel: Snoopy is abused and starved, becomes evil, and then dies getting pulled into a frozen lake (alongside the other sled dogs and the cruel master), screaming and clawing for his life. One could argue that this was inappropriate for the Peanuts specials' target audience.
 * Took a Level In Jerkass: Snoopy becomes as to the other sled dogs as they were to him.
 * The Woobie: Snoopy.
