Abstract

Family dogs successfully follow human-given cues in a two-object choice test. However, whether this ability has any roots in dog-dog visual communication, has been seldom investigated. We designed a test where a video-projected, life-sized dog 'demonstrator' provided directional cues for the subjects by turning its head toward one of the two plates containing food. To avoid pseudo-replication, videos of 28 different dogs were recorded as 'demonstrators'. N=60 subjects were tested with a larger, smaller, or equally sized 'demonstrator', using a momentary head-and-gaze turn, while N=15 subjects were tested using sustained demonstrative cues. Social status of the subjects, based on a questionnaire (single-kept, dominant or subordinate), was also taken into account. Our results showed that dogs did not choose between the plates by relying on the momentary head turns of the projected demonstrator ( p=0.35). Social rank did not have any effect on their choices either, however, 'single' dogs showed a left-side preference in their choices ( p=0.03). In the case of momentary gazing, all dogs developed strong side bias depending on their first choices ( p
