Dogs recognise facial features

Dogs can recognise the faces of familiar people and canine pals, a new study finds.
The recognition of facial features is a specialised skill previously thought to be unique to people and possibly other primates, the University of Helsinki researchers said.

It’s long been known that faces and eye contact play an important role in communication between people and dogs. Now, a new study is believed to be the first to use eye movement tracking to investigate the facial recognition ability of dogs.

Eager to participate
The eye movements of the dogs in the study were assessed while they were shown photos on a computer screen of people and dogs. These included images of their owners or another dog in the same family, and images of unfamiliar people and dogs.

The dogs scanned the familiar faces more thoroughly than the unfamiliar faces, which indicates that they were able to distinguish between the faces, according to the study published in the journal Animal Cognition.

“Dogs were trained to lie still during the image presentation and to perform the task independently. Dogs seemed to experience the task [as] rewarding, because they were very eager to participate,” study leader Outi Vainio said in a university news release.
