The team hope it will help people communicate better with their animals.
Our science correspondent Victoria Gill has the story.
A total of 14 dogs were involved in the study.
Six good boys and eight good girls all trained to sit very still in a brain scanner while they were showing pictures of people's faces.
Photos of smiling human faces of complete strangers made an area of the dog's brain associated with reward light up with activity.
That reward circuitry is the part of the brain that's activated when we enjoy and remember good things like tasty food or praise.
In terms of our own human brains, we often refer to this activation as a dopamine hit that's triggered by winning a game or even receiving a positive comment on a social media post.
And in previous research on dogs, that same brain circuitry was activated when they anticipated a tasty snack or smelled a familiar person.
So this study shows, scientists say, that a human smile is a positive, rewarding thing for a dog.
The project was led by researchers at the University of Vienna, and one of the lead scientists, Raúl Hernández-Pérez, says it's part of an ongoing series of studies that's showing how life with humans has reshaped the brains of our canine companions.
Another lead scientist on the study, Laura Quire, says the insights could even help us to understand and communicate better with our own dogs.
the relationship will improve.
One simple thing you can do to improve that relationship, smile more at your dog.
You heard it here first, smile at your dog.
