“…Once an effective behavioral test is developed, it would be useful to examine the consistency of behavioral traits to determine whether or not these traits can be influenced by environment. Additionally, these assessable traits are expected to play a role in canine behavioral genetics [8,16], promoting the identification of temperament-associated genes [7,17,18] and contributing to the establishment of breeding protocols and the development of tailor-made training programs. By combining several assessments that focus on important behavioral traits and genetic information, it may be possible to provide an early and highly accurate prediction of guide dog qualification, which would help address the guide dog deficit.…”

Important Behavioral Traits for Predicting Guide Dog Qualification

ABSTRACT. Guide dogs for the blind help blind people physically and mentally in their daily lives. Their qualifications are based on health, working performance and temperament; approximately 70% of dogs that fail to qualify are disqualified for behavioral reasons. In order to achieve early prediction of qualification, it would be essential as the first step to identify important temperament traits for guide dogs. Therefore, we administered a questionnaire consisting of 22 temperament items to experienced trainers to assess candidate dogs at the Japan Guide Dog Association after three months of training, which was at least three months prior to the final success (qualified as a guide dog) or failure (disqualified for behavioral reasons) judgment. Factor analyses of question items stably extracted three factors with high internal consistency, Distraction, Sensitivity and Docility. When we compared factor points between successful dogs and failed dogs, the successful dogs showed significantly and consistently lower Distraction points and higher Docility points. Additionally, Distraction points could predict qualification with 80.6% accuracy and detect 28.2% of the failed dogs that had higher Distraction points than any of the successful dogs. Of the nine question items not included in the three factors, two items ('Aggression' and 'Animal interest') were consistently associated with qualification. These results suggest that Distraction is stably assessable and has the strongest impact on success or failure judgment; therefore, it will be the first target to establish a behavioral test that may lead to early prediction of guide dog qualification.KEY WORDS: behavior, canine, guide dog for the blind, questionnaire, temperament.

Owners filled out the Dog ADHS-RS questionnaire measuring activityimpulsivity and inattention. video rating of activity-impulsivity correlated with the scale scores of the owner, but video codings did not. the results suggest that the owner ratings and video ratings are tapping the same constructs, but behavioural variables assessed in the present study were not appropriate for mirroring the owners' assessments. The findings suggest that if consistent individual differences in broad behavioural traits are the primary focus of analyses, then ratings seem to capture information not easily captured in coding approaches designed to assess the same constructs.

“…The traits 'initiative' and 'not mistrustful with unfamiliar humans' were assumed to show association with the latency of approaching the experimenter ('stranger') in the Greeting test and the duration of playing with the experimenter. Both of these traits and test battery variables were supposed to be related to dogs' contact seeking behaviour towards unfamiliar humans (see "social impulsivity" in Héjjas et al, 2009). …”

In this paper our first aim was to investigate association between behaviour coding based on a test battery called the FIDO Personality test for dogs (Canis familiaris) and a subjective rating given by dog owners. For the latter we asked dog owners to fill in the Dog Personality Questionnaire (DPQ) which established four personality traits for dogs: Strangerdirected Sociability, Activity, Aggressiveness and Trainability. The FIDO Personality test consists of a series of subtests in which we utilised an ethogram and measured different aspects of dog behaviour. Prior to this study we established a set of possible associations between the behavioural and the questionnaire variables.With regard to Trainability no correlation could be detected between any of the questionnaire variables and the hypothetically corresponding test battery variables. In the case of Stranger-directed Sociability, we revealed correlation between owners' reports and the dogs' behaviour during the test stuation. Those dogs which were reported 'initiative' and 'not mistrustful with unfamiliar humans' approached the experimenter with shorter latency (r = -0.25, p < 0.01; r = 0.24, p < 0.01) and played more with her than those who were scored lower on these questionnaire items (r = -0.27, p < 0.01). For the factor Activity, no correlation was found between the owners' report and the behaviour of dogs displayed in the Spontaneous activity phase of the test battery. Association was revealed between the owners' report regarding the dogs' preference for ball games and playing and their behaviour in the corresponding subtest. Those dogs which were reported to like ball games and like playing with the owner played with the ball as well as with a tug more in the test situation than those which were scored lower on the questionnaire variable 'likes fetching balls'(r = 0.47, p < 0.001; r = 0.25, p < 0.01). As regards the factor Aggressiveness, the questionnaire variable 'shows a tendency to bark' correlated with the dogs' aggressive reactions (growl, bite, attack) (r = 0.25, p < 0.01) in the Bone take-away subtest and with the 'latency of getting the DNA sample' (r = 0.30, p < 0.001) in the Getting DNA sample subtest. The results show that despite of the investigated associations there is a need for more effort to refine both questionnaire-based and behaviour-based assessment of dog personality.The second aim of our experiments was to reveal whether owner ratings on the above personality factors converged with the ratings of independent groups of observers based on the video recordings of the FIDO Personality test. First, in the case of each factor, we compared the degrees of ratings given by the owners and by the three rater groups with different levels of hands-on experience with dogs. We found no difference in the case of Stranger-directed Sociability, Activity and Trainability (F(3,128)=1.17, p=0.17; F(3,128)=0.99, p=0.4; F(3,128)=1.6, p=0.18 respectively) but there was a significant variability in judging Aggressiveness (F(3,128)=2.86, p=0...
