Attention towards a handler in behavioural tests contributes to low ‘Distraction’ in guide dogs

Guide dogs are one type of assistance in Japan that help individuals who visually impaired. The qualification candidate is judged based on temperament and health. Previously, our group showed ‘Distraction’ was the most influential behavioural trait for at Dog Association (JGDA). In this study, to examine underlying sub-traits associated with ‘Distraction’, we conducted tests focusing overall activity degree which they paid attention a handler. subjects were 59 guide (Labrador Retrievers) born reared JGDA. At 7 weeks age, measured responses under following situations: Isolation (5 min), Experimenter Entering Elevation (30 s), Restraint s). 14 months age (during second month training), physiological (heart rate) Kennel (10 min). When 15 third asked experienced trainers complete questionnaire calculate score. We used multiple regression analysis (MRA) association between score, responses, age. found lower scores, i.e., less distractable, spent more time engaged “struggle” behaviour condition “active movement” had higher heart rate condition, “gaze” condition. According coefficient determination standardized coefficients MRA, comparatively large effect. Therefore, towards handler, interpreted as “gaze”, appears be an important sub-trait compared activity. These findings expected contribute improving training efficiency through modification both breeding strategy.
