In my blog, "Man's Best Friend" I told you about dog's history and some of it's behavior. And here I will tell you it's participation to us, by our movements.

A dog and a monkey was tested, on who is more cooperative. The test had three materials. Two upside down cups and a piece of treat, under one of the bottom up cups.
It was shown to a monkey, (they say, the close to our kind) but before that, the experiment was shielded, so the monkey can't see where the treat was placed. The scientist pointed the the cup with the treat, but the monkey did not cooperate and pointed the opposite cup. So no treat.
It was the dog's turn, the experiment was repeated, and the dog listened, based on the pointing of the scientist, it had a treat. The scientist also pointed the the cup with the treat with it's eye movement. The dog listened and again got a treat!
So, what is the explanation in this situation. The reason why the monkey didn't participate, is because it is not interested in our environment, and has it's own environment, like it's self-reliant. While the dog, also has it's environment. And it is us. They rely their lives on us. We have their food and shelter. They are a part of us, and our behavior can also affect theirs.
