text: Spin-offs In another series of Warner Bros. Looney Tunes cartoons, Chuck Jones used the character design (model sheets and personality) of Wile E. Coyote as "Ralph Wolf". In this series, Ralph continually attempts to steal sheep from a flock being guarded by the eternally vigilant Sam Sheepdog. As with the Road Runner and Wile E. Coyote series, Ralph Wolf uses all sorts of wild inventions and schemes to steal the sheep, but he is continually foiled by the sheepdog. In a move seen by many as a self-referential gag, Ralph Wolf continually tries to steal the sheep not because he is a fanatic (as Wile E. Coyote was), but because it is his job. In every cartoon, he and Sam Sheepdog punch a timeclock and exchange pleasantries, go to work, stop what they are doing to take a lunch break, go back to work and pick up right where they left off, and clock out to go home for the day and exchange pleasantries again, all according to a factory-like blowing whistle. The most obvious difference between the coyote and the wolf, aside from their locales, is that Wile E. has a black nose and Ralph has a red nose.
  Comic books
  Wile E. Coyote was called Kelsey Coyote in his comic book debut, a Henery Hawk story in Looney Tunes and Merrie Melodies #91 (May 1949). He only made a couple of other appearances at this time and did not have his official name yet, as it was not used until 1952 (in Operation: Rabbit, his second appearance).
