No, Wile E. Coyote didn't enter the Witness Protection Program, not that it would do him any good.
Ralph Wolf only looks like Wile, but then again, wolves & coyotes are cousins. Chuck Jones decided to try out Ralph and Sam Sheepdog in a series of shorts that had minimal dialogue (spoken by Mel Blanc), but plenty of gags and pratfalls for Ralph.
Imagine if wolves & sheepdogs had to punch in and out of work like us humans? Oh, this is just wiggedy wack! Here's "A Sheep in the Deep".
It's just too bad that while this was included in a Bugs Bunny compilation movie ("1001 Rabbit Tales"), Ralph & Sam haven't exactly been treated with respect by later generations at WB. As in, not getting any attention at all.
