Dogs can read emotion in human faces

Dogs are the only animals that can read emotion in faces much like humans, cementing their position as man's best friend, claim scientists.

Research findings suggest that, like an understanding best friend, they can see at a glance if we are happy, sad, pleased or angry.When humans look at a new face their eyes tend to wander left, falling on the right hand side of the person's face first.This "left gaze bias" only occurs when we encounter faces and does not apply any other time, such as when inspecting animals or inanimate objects.A possible reason for the tendency is that the right side of the human face is better at expressing emotional state.
