Previous work assessing companion dog behavior has often focused on negatively-valenced behaviors, such as aggression and fear, which may lead to an incomplete understanding of dog reactions. To gain a better understanding of companion dog behavior, we compared responses to four stimuli (live dog, model dog, novel object, and control). We recorded the reactions of 26 dogs to these stimuli and coded their behavior with an ethogram developed from a review of the literature. The ethogram included behaviors typically associated with both positively- and negatively-valenced emotional states. We used principal component analysis to examine whether the behaviors reliably cluster according to positive versus negative valence. We predicted that behaviors would group according to the valence suggested in the literature; we also predicted that there would be a negative correlation between the expression of fear behaviors and positively-valenced behaviors. We are currently comparing our data with individuals’ scores on the validated Canine Behavioral Assessment & Research Questionnaire (C-BARQ) as well as the Canine Body Language Questionnaire (CBLQ), a pictorial questionnaire in development.
