T.U.F.F Puppy Theme Song lyrics

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 that 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
