Yes, dogs can 'catch' their owners' emotions

Dog-owners often feel that their pooches are good at picking up on their emotions. New studies show how behavioral and chemical cues from humans can affect dogs in ways that enable them to not only discriminate between their owners' fear, excitement, or anger, but also to "catch" these feelings from their human companions. Just as human toddlers look to their parents for cues about how to react to the people and world around them, dogs often look to humans for similar signs. When their people project feelings of calm and confidence, dogs tend to view their surroundings as safe and secure. "The emotional connection between humans and dogs is the essence of the relationship," says Clive Wynne, a professor of psychology and director of the Canine Science Collaboratory at Arizona State University.
