Plenty of pet owners are comforted by a pair of puppy-dog eyes or a swipe of the tongue when their dog catches them crying. Now, new research suggests that dogs really do respond uniquely to tears. But whether pets have empathy for human pain is less clear.
In a study published online May 30 in the journal Animal Cognition, University of London researchers found that dogs were more likely to approach a crying person than someone who was humming or talking, and that they normally responded to weeping with submissive behaviors. The results are what you might expect if dogs understand our pain, the researchers wrote, but it’s not proof that they do.
