Assessing welfare in sanctuary animals requires tools that measure both absence of suffering and presence of positive states for animals with permanent conditions.
Sanctuary animal welfare is a long-term welfare management challenge that differs from acute care. Animals with permanent conditions — the three-legged dog, the blind cat, the chronically ill rabbit — can live excellent lives when their specific needs are understood and met, but require ongoing assessment to detect deterioration early. Quality of life assessment tools adapted for different species and conditions help sanctuary staff and owners make consistent welfare judgments rather than relying on subjective impressions that may be influenced by emotional attachment. Regular assessment with documentation allows tracking of welfare trajectories over time.
