When dogs roll over onto their backs and expose their bellies, their behavior is a sign of submission, right? Well, new research suggests that we may be interpreting canine body language all wrong.

A new study by researchers at the University of Lethbridge in Canada and the University of South Africa shows that rolling over may be more of a combat maneuver than an act of submission.

For the study, the researchers observed a medium-sized female dog as she played one at a time with 33 different dogs. They also analyzed 20 YouTube videos showing dogs at play–examining each time a dog rolled over onto its back.
