Maggy barks a lot when we're outside with her. I guess she feels the need to notify the other dogs that we're outside. She also barks when she hears the doorbell. One thing that sets her off is hearing the baby gate move. We used it a lot when she was a puppy, now she's afraid of it. Anytime she hears it move....ARRFFF ARRFFFF ARRFF ARRF!!! Silly girl.
