The Five Domains model provides science-based comprehensive animal welfare assessment covering nutrition, environment, health, behaviour, and mental state — moving beyond minimum standards to genuine flourishing.
The Five Domains model is significant because it explicitly addresses positive welfare — not just the absence of suffering but the presence of positive experiences including pleasure, comfort, and engagement. This shifts welfare assessment from a deficiency model (what is wrong?) to a flourishing model (what is good, and how can it be improved?). Domain 5, mental state, integrates physical and behavioural welfare into an assessment of subjective experience that gives the framework its distinctive welfare-positive character. Applied systematically, it identifies both welfare deficits requiring correction and welfare opportunities — chances to improve positive experience — that standard compliance frameworks miss entirely.
