Do you want to listen to his dog all day while all other players listen to his cat and are basically creating a space-time paradox impossibility of listening to the same thing with different results? Then you're in luck! This handy-dandy pack changes the music disc 'cat' to 'dog'!
In some earlier versions of Minecraft the music disc will still be named 'cat' but in later versions it is renamed to 'dog'.
