Dave is a fairly placid family dog. There’s not a lot that ruffles him, except for one song.

Dave doesn’t mind music at all. He’s happy for his owners to sing just about anything. They just can’t sing “Happy Birthday!”

This video shows what happens when Dave’s owners break that cardinal rule. We see the Mr Hyde side of this mild-mannered pup as he barks and runs around in circles, visibly distressed. I’ve heard of some weird phobias, but this one takes the cake!

It’s kind of amusing to see this bizarre behavior here, but it can’t be much fun at birthday parties!
