Behavioral assessment of shelter dogs aims to predict suitability for different home environments, but must balance reliability, humaneness, and welfare during testing.
Shelter behavioral assessment has significant welfare implications: unreliable tests can result in adoptable dogs being euthanized, or problematic dogs being adopted into unsuitable homes. The welfare impact of assessments themselves must also be considered, as provocative tests involving food removal or fake hand insertion cause measurable fear and stress. Current best practice favors low-stress, positive assessment approaches combined with detailed behavioral observation during normal shelter interactions. Extended foster placements provide the richest behavioral data for adoption matching.
