Opening 038

Dudley in the T.U.F.F. Puppy logo.

The Theme Song is the song played on every opening sequence of T.U.F.F. Puppy. It was written by Adam Schlesinger and Butch Hartman.


Dudley Puppy was a plain old mutt
(plain old mutt)
He'd scratch, he'd dig and then he'd chew his butt
(chew his butt)

But when bad guys got too rough
He went to work for T.U.F.F.
And now he's doing secret agent stuff


He's a T.U.F.F. Puppy
T.U.F.F. Puppy
He's a T.U.F.F. Puppy

A dog who sticks his nose right where he knows the crooks will be.


He's a T.U.F.F. Puppy
T.U.F.F. Puppy
He's a T.U.F.F. Puppy

(electric guitar plays)


  • The end credits have an instrumental version of the theme, without the lyrics.
  • The theme song is a parody of another song called Secret Agent Man by Johnny Rivers.
  • In later episodes of season 2, Snaptrap is in his rounder redesign for the opening.
    • This is also when Snaptrap plays the guitar for the first time.
    • Additionally, Kitty and Keswick's screams at their guitar scenes are now muted.
