At one time I had two dogs. One was named Magic and she would bark loudly and seriously if anyone or anything was in my yard or close to my house. I trusted her. She was my best friend.
Magic had a puppy who was almost solid black. I named her Blackie. Blackie was often referred to as “the other dog” because she followed Magic’s lead. Except when it came to barking. Oh, she would bark, if Magic did, but if she heard something Magic did not seem to hear, Blackie would crawl under the bed and do what I referred to as “whisper bark”. She would “woof, woof” barely loudly enough to be heard. It was a whisper barking as if she hoped someone would handle the fear she felt, without anyone knowing she was aware of whatever had caused her to go under the bed and hide.
My son kept both dogs one weekend when I went out of town. When I returned and asked how everything went, he said Magic made him feel safe since she only barked when someone would pass the house, but Blackie freaked him out by crawling under the bed and barking softly from time to time. He had no idea what she’d heard and he could never find anything.
Magic has crossed the Rainbow Bridge, but Blackie is still with me. She still hides and whisper barks. The dog I got to help her out of her grief stricken state when Magic passed away will also go under the bed when Blackie begins to hide and whisper bark. I didn’t think it could get any worse, but obviously it could. Now I have two dogs who hide when scared and only one of them is brave enough to bark, and she whispers when she does.
