Owner-reported personality assessments are associated with breed groups, but not with oxytocin receptor gene polymorphisms in domestic dogs (Canis familiaris)

Variation in the oxytocin receptor (OXTR) gene has been linked to dog social behavior in some studies, while others have failed to replicate this relationship (in dogs and other species). Ratings of observed behavior are often used to assess personality, however owner-based behavior/personality assessments have been shown to be comparably consistent. The relationship between OXTR gene variation and behavior as measured by owner-based personality questionnaires has yet to be explored in dogs. The aims of our current study were three-fold: (1) to investigate the relationship between two OXTR SNPs (rs8679684 and 19131AG) and three owner-based behavior/personality measures in dogs (the MCPQ-R, a history of aggression questionnaire, and an “eagerness to please” scale), (2) to explore the relationships of personality assessments and OXTR polymorphisms with genetic breed clusters, purebred versus mixed breed status, and how the dog was acquired (shelter versus other means), and (3) to examine the relationships among the three owner- based assessments.
