From the recording Mid-Life Angst
Shhhhh, this song is a secret. It was never meant to be included, has 20 seconds of silence to start, and no mention on the CD packaging. But after caving to my indecision and including "LoveLetter" I decided to leave nothing on the cutting room floor. "Pig Dog (a different one)" is a "campy electronica" instrumental with minimal stupid lyric revisiting the earlier Pig Dog theme.
Lyrics
Pig Dog.... Pig, Pig Dog.
