Dogs may have evolved to handle our bad tempers

Man’s best friend has a clear strategy for dealing with angry owners — look away.
New research shows that dogs limit their eye contact with angry humans, even as they tend to stare down upset canines. The scientists suggest this may be an attempt to appease humans, that evolved as dogs were domesticated and benefited from avoiding conflicts with humans.
To conduct the tests the University of Helsinki researchers trained 31 dogs to rest in front of a video screen. Facial photos — showing threatening, pleasant and neutral expressions — were displayed on the screen for 1.5 seconds. Nearby cameras tracked the dogs’ eye movements.
Dogs in the study looked most at the eyes of humans and other dogs to sense their emotions. When dogs looked at expressions of angry canines, they lingered more on the mouth, perhaps to interpret the threatening expressions. And when looking at angry humans they tended to avert their gaze. Dogs may have learned to detect threat signs from humans and respond in an appeasing manner, according to researcher Sanni Somppi. Avoiding conflicts may have helped dogs — which are the most popular pet in the United States — develop better bonds with humans.
