My problem: Our yappy little dogs

Lucky me....our Shih-Tzu, we found out, simply likes to sit on the back of the couch and look out the window. We found that out from next door "neighbors"...after we asked them to simply observe (and report) when we left for the afternoon...or even for an hour or so.
Of course, when another dog walks by..........but then it stops when the other dog is out of sight.
