Here, we examined which human communicative factors were important in influencing dogs’ responses. Eleven healthy pet dogs with no apparent aggressive behaviour toward people were recruited. Five sensory conditions (all cues presented;either a visual, an auditory, or an olfactory cue presented;no cues presented) were provided three times randomly to each dog during the tests. All tests were video recorded, and both the dogs’ behaviour and time taken to reach the person when she presented each of the sensory cue conditions were observed. Total rates of reaching the person were as follows: 97.0% (all cues), 87.9% (auditory cues), 84.4% (visual cues), 84.4% (olfactory cues), and 69.7% (no cues). The time taken for the dog to notice the person in the box and then obtain a reward from her differed among the five conditions: all cues (6.00 ± 0.32 s) and visual cues (6.02 ± 0.91 s) were significantly faster than auditory cues (18.56 ± 9.57 s) and no cues (26.55 ± 11.72 s). Thus the type of information input was important in recognition of the person by the dogs and influenced the dogs’ response times;visual cues appeared advantageous in confirming the person’s presence.展开更多
