As everyone knows dogs do recognize their owners... in the flesh! But what about photos or videos? A new eye-movement study from the University of Helsinki in Finland showed that dogs recognize us in images too. Barking! 

31 dogs watch videos of displaying faces of humans and dogs. Some were familiar faces like owners, or dogs of the family, and some were strangers.

The results confirm that dogs are able to perceive faces in the images, says study leader Dr. Outi Vainio. And, dogs were more likely to fix their gaze on the image of a familiar face than that of a stranger.

But dogs are even more likely to fix their gaze on other dogs, whether they are familiar dogs or not!

This new research was published online this month in the journal Animal Cognition.
