The study is one of the first of its kind. Chopik and his team surveyed the the owners of over 1,600 dogs, including 50 breeds. Pup-participants ranged from just a few weeks to 15 years and were nearly evenly split between male and female. Chopik created an extensive survey for owners to evaluate their dog’s personality traits, as well as their own characteristics, and answer questions about their dog’s behavioral history.
The study was published in the Journal of Research in Psychology.
