Absolute truth when it comes to dachshunds--even if a noise sounds like a knock, they're all over it! Sometimes, if I close a closet door or open a drawer, Duke barks like mad. It can get annoying, but sometimes it's a good thing that he barks when an unusual noise occurs. He's our watchdog, you know.
Dachshunds . . . you gotta love 'em, even when you want to strangle 'em!
