University of Helsinki published the results of dog behavior and personality survey at Petsofi in January 2019. The results were based on over 1000 answers and now there already over 6000 answers. The reliability of results increases as number of answers grow. The new answers were analyzed again and based on that the results have been updated.
Most of the results remained the same, but separation anxiety, aggressiveness and personality results have changed. Separation anxiety is now only one trait (separation anxiety), and aggressiveness is two traits (meeting aggression, and handling and resource aggression). The personality got one trait more, and it is composed by eight traits: insecurity, attention/obedience, calmness, energy, dominance, dog sociability, human sociability, and perseverance.
The survey does not require re-filling. You can see the updated results right away in Petsofi.
