Breed: Sheepdog

Original Appearances: Looney Tunes cartoons, starting with “Don't Give Up the Sheep” in 1953.
Other Appearances: Sam has appeared in a number of other Looney Tunes-related products since 1988, including at least one video game.
Biography: Unknown. Sam is on a regular shift as a sheepdog guarding a herd of sheep. We don't know anything about his home life... at least, I don't recall anything.
Powers: Amazing strength. Possibly the ability to teleport, as we rarely see him move, yet manages to appear where he needs to be. Can see through any disguise of Ralph Wolf's (see separate entry).
Group Affiliation: Presumably a member of a sheepdog union of some kind.
Miscellaneous: None.
