Today I read an article that talked about a study where they tested if people love their dogs the same way they love their human children. The control group had people in a play session with their dogs and the experiment group was the same except they had to gaze into their dogs eyes. Both groups were tested and they found that those who looked into their dogs eyes had elevated levels of oxytocin which is a chemical that make you happy.

I wonder if it would work from looking at this picture of my dogs?
