Dogs yawn when they see their owners yawning, a new study found.
We have all experienced that moment when one person yawns and everybody in the group starts yawning. Experts say that group yawning is empathetic and might help increase vigilance of the entire group.
Now a new study, conducted by Teresa Romero and colleagues at University of Tokyo, has shown that even dogs begin yawning after seeing their masters yawn.
In the study dogs watched their owners or strangers yawn or make facial expressions that mimic yawning. Researchers found that dogs were more likely to yawn when their masters yawned when compared to strangers.
