We have three dogs left and two of them are getting up in years. The two females (one is the oldest dog and the other is the youngest, the male is in between) are into this electronic age; the male, not so much. The youngest one spends a lot of her leisure time watching the monitor which is connected to our outside security cameras. She alerts the others to any stray dogs (or other animals) that may pass by. They all watch it when we leave the house. My wife was outside yesterday and they kept close track of where she was and when they saw her come up the steps to the deck, they all ran to the door to greet her.
Our oldest one watches TV. We haven't as yet caught up with the new style digital TVs, but just have an old 32 inch cathode ray tube type that weighs a ton or two. I have read where it stated that dogs can't see that type of TV because most of them need about 70 images per second to see a continuous film but we humans only need about 16 to 20. All my TVs are of the old style as is the security monitor. Both the females watch the monitor and only the oldest one watches the TV and barks at other dogs, but not other animals, when seen on the TV. This proves that she sees it as a moving film and recognizes what it is showing.
As I said above, my wife walked outside early last evening and the female pups ran to watch her in the monitor. They seem to know exactly what they are seeing on it and where it is that the views are coming from. How do I know this? Well, last night they watched my wife on the monitor go outside, turn left and walk out of site. They ran to the sliding glass doors on the rear of the house to meet her there instead of the door that she went out of. Animals are more intelligent than we generally give them credit for, except maybe our male. But like most boys, he only has one thing on his mind. . . , well, maybe two things. The second is food. So have a great day and hope our dogs see you all in our monitor some day, you hear.
