Watched the program where they describe how dogs typically react to it and it described my dog's reaction perfectly. They don't become couch potatoes and stare at it non-stop, but rather treat it as background much of the time, watching it only from time to time. That's exactly what my dog does. From time to time she gets interested and looks at it. When there are other dogs on the screen she frequently goes up to the television and starts sniffing around it (frequently sniffing the front speaker where she hears the sounds coming from). But there have also been times when she got interested in looking at some of the abstract moving patterns they put on the screen. Obviously, not everyone's dog will get into it. But, from what I've seen of my dog's reaction, I'm interested in getting it for her when my wife and I are away at work and she's left alone in the house. I think it may make the time alone a bit more bearable for her.
