WE'VE ALL HEARD IT AT SOME POINT OVER THE LAST THREE OR FOUR DECADES: THE DOGS BARKING JINGLE BELLS. SOMETHING IN NEVER NOTICED BEFORE, THOUGH, WAS THE INSTRUMENTAL SECTION. I THINK IT'S AMAZING THEY WERE ABLE TO TEACH THE DOGS TO BARK ON KEY... BUT I WAS BLOWN AWAY TO REALIZE THEY ALSO TAUGHT THE DOGS PLAY MUSICAL INSTRUMENTS.
