Abstract	Eye movement of a species reflects the visual behavior strategy that it has adapted to duringits evolution. What are eye movements of domestic dogs (Canis lupus familiaris) like? Investigations of dog eye movements per se have not been done, despite the increasing numberof visuo-cognitive studies in dogs using eye-tracking systems. To fill this gap, we have recorded dog eye movements using a video-based eye-tracking system, and compared the dogdata to that of humans. We found dog saccades follow the systematic relationships betweensaccade metrics previously shown in humans and other animal species. Yet, the details ofthe relationships, and the quantities of each metric of dog saccades and fixations differedfrom those of humans. Overall, dog saccades were slower and fixations were longer thanthose of humans. We hope our findings contribute to existing comparative analyses of eyemovement across animal species, and also to improvement of algorithms used for classifying eye movement data of dogs.
