Dogs are a man’s best friend, as the saying goes, and now, researchers say they have more proof that just like friends, dogs are tuned in to their owners’ emotions.
In a study published Wednesday in the open-access journal PLOS ONE, University of Tokyo researchers say dogs are more responsive to their owners’ yawns than to strangers’ yawns — a sign that canines are more empathetic than previously understood.
For the study, the researchers studied 25 dogs in their owners’ homes. Researchers recorded their responses to watching their owners yawn, then watching an unfamiliar researcher yawn. They yawned nearly fives times more often in response to their owners’ yawns.
Earlier studies have shown that when humans yawn contagiously, or in response to another human’s yawn, it is a sign of empathy and social skills. On the flip side, people with empathy disorders, such as autism, are often not prone to contagious yawning.
