Behavioral assessment of shelter dogs determines adoption suitability and euthanasia decisions. Modern behavioral science has improved assessment accuracy while reducing welfare harm from outdated testing protocols.
Shelter behavioral assessment has significant welfare implications: dogs euthanized based on inaccurate assessments that reflect shelter stress rather than true temperament are welfare victims of the assessment process itself. The scientific critique of traditional behavioral tests like SAFER is not that behavioral assessment is wrong, but that single-session high-stress protocols produce unreliable information that costs lives unnecessarily. Modern sheltering science advocates for extended observation across multiple contexts, focus on finding appropriate placements rather than pass-fail judgment, and provision of behavioral support to adopters rather than requiring perfect dogs for adoption. This approach saves more lives while improving welfare of adopted dogs through better adoption matches.
