The science behind behavioral assessment tools used in shelters to evaluate adoptability, reduce euthanasia, and match animals with appropriate homes.
Behavioral assessment tools in shelters carry enormous welfare stakes: an incorrect classification of aggression can be a death sentence for a healthy, adoptable animal. The evidence is increasingly clear that many traditional in-shelter assessment protocols overestimate aggression risk because shelter environments themselves trigger defensive behaviors. Progressive shelters are moving toward longer observation periods, foster programs, and expert behavioral consultation before making euthanasia decisions based on assessed behavior. The goal of assessment should always be to find a path to placement, not to justify euthanasia of animals who may simply be responding normally to an abnormal environment.
