Question design

Informed by C-BARQ and C-BARQ-S owner-questionnaire logic, with questions limited to observable daily behavior.

Hsu & Serpell · Wilkins et al.

02

Personality stability

Informed by dog personality judgment and temporal-consistency research; results are framed as tendencies, not destiny.

Overall framework

03

Axis sources

Informed by canine temperament, curiosity, social-cue sensitivity, breed behavior differences, and human-pet attachment work.
