Noelle isn't a barker either but she did try to warn me of the evil dog in the dishwasher! LOL! She noticed her reflection in the front of the dishwasher, stopped, glared, backed up, and charged barking furiously! She looked at me and charged the dishwasher again! She kept it up until I picked her up, touched the dishwasher and tried to reassure her. She still walks by the dishwasher with a nasty sideways glance with a low growl.
