My dogs bark for all the usual reasons, mostly warning me that something is going on outside. The other day my Black Mouth Cur (hound dog) followed me all around the house whining softly. I knew she was trying to tell me something but I didn't realize what it was until I went to our bedroom.
She went over to her bed in the corner and whined louder.
One of the little Jack Russels had peed in her bed and she wanted it cleaned up. As soon as I took her bed to wash it she never whined again. Cate is a great dog! :)
