Mean owner-reported Canine Behavioural Assessment and Research Questionnaire (C-BARQ) scores for main behavioural categories for Labrador Retrievers (n = 2597), Labradoodles (n = 166), Standard Poodles (n = 597) and Miniature Poodles (n = 258). Model interactions between breed and other fixed effects are also reported. Breed comparison indicates when breeds differed.
