Gazing as a help requesting behavior : a comparison of dogs participating in animal-assisted interventions and pet dogs

Abstract

Dogs tend to gaze at humans when they are confronted with inaccessible food during an unsolvable task, which is often interpreted as a help requesting behavior. Dogs who participate in animal-assisted interventions (AAI) interact with many people during their lives and prior studies have emphasized the importance of gazing in their communication. We compared the behavior of AAI (n=15) and pet (n=16) dogs during an unsolvable task, using a container fxed to a wooden board with inaccessible food inside, while the owner and an unfamiliar woman stood facing each other at the sides of the board ignoring the dog. Results showed that AAI dogs spent signifcantly more time gazing and alternated their gaze more frequently between the container and the people than pet dogs. In addition, they spent more time in contact with the unfamiliar person. However, no signifcant diferences were found in the time dogs of either group gazed towards the owner compared to the unfamiliar person, in the frequency of gaze alternation or in the time spent interacting with the apparatus. In line with prior studies,these results suggest that gazing may be a signifcant communicative response in AAI dogs, which could probably contrib-ute to having a better coordination with their handler. A greater understanding of the characteristics of this population may aid the selection and training of AAI dogs, which is particularly relevant given the increased popularity of AAI nowadays.
