Dogs yawn contagiously when they see a person yawning, and respond more
frequently to their owner’s yawns than to a stranger’s, according to a
new study.
This contagious yawning between dogs and their owners suggests pet-human
empathy, researchers believe. University of Tokyo researchers studied
pet dogs while they watched their owner or a stranger yawn, or mimic a
yawning mouth movement.
The dogs yawned significantly more in response to their owners’ actions
than to the strangers’ yawns, the study found. The canines also
responded less frequently to the fake movements, suggesting they have
the ability to yawn contiguously. Previous research has shown that dogs
yawn in response to human yawns, but it was unclear whether this was a
mild stress response or an empathetic response.
The results of this study suggest the latter, as dogs responded more to
their owners’ genuine yawns than those of a stranger, researchers said.
They observed no significant differences in the dogs’ heartbeat during
the experiments, making it unlikely that their yawns were a distress
response.
