As most dog lovers will happily tell you, these animals are very in tune with humans. New research suggests they can read human emotions--regardless of language. In a research study, dogs were shown side-by-side images of two humans or two dogs. Each image was showing positive or negative emotions. These photos were paired with audio recordings that went along with the corresponding emotion. The dogs participating in the study looked in the direction of the image that went with the sound--very cool!
