Dogs may indeed be able to discriminate between happy and angry human faces, according to a new study. During the training stage, each dog was shown only the upper half or the lower half of the person’s face. The investigators then tested the pups’ ability to discriminate between human facial expressions by showing them different images from the ones used in training. The dogs were shown either the other half of the face used in the training stage, the other halves of people’s faces not used in training, a face that was the same half as the training face but from a different person, or the left half of the face used in the training stage.
