Emmy-Lou was a Russian wild boar that portrayed Worf's pet targ in the Star Trek: The Next Generation first season episode "Where No One Has Gone Before".

According to Robert Justman, "That pig smelled horid. A sweet-sour, extremely pungent odor. I showered and showered, and it took me a week to get rid of it!" (Star Trek: The Next Generation Companion 2nd ed., p. 37) In addition, the boar left a distinctive "spot" on the bridge set which remained until the end of the first season. (Star Trek Encyclopedia 2nd ed., p. 497)
