“Fuck a Dog” is one of the three bonus joke tracks released on blink-182’s 2001 album Take Off Your Pants and Jacket. It was released on the Yellow “Pants” version of the album along with B-side “What Went Wrong”. It serves as an outro to this version of the album and it’s one of the most iconic examples of the band’s cheeky humor.

Blink wrote this song and “When You Fucked Grandpa” as a symbolic big middle finger to MCA Records. They noted an immense pressure from MCA to write a carbon copy of Enema of the State, so they decided to play a prank on them as Tom DeLonge detailed in 2012 for Music Radar:

I remember the label came down to hear the big follow-up and those were the only songs [“Fuck a Dog” and “When You Fucked Grandpa”] we played them. Oh my God, they lost their minds. We had this song about fucking Hitler — we changed it to ‘When you fucked grandpa’, but it originally was, ‘When you fucked Hitler did he tell you that he loved you?’ They lost it.
