The Five Freedoms remain the most widely used animal welfare framework globally — a landmark framework that continues to evolve as welfare science advances toward positive welfare.
The Five Freedoms provided a simple, powerful, and practically applicable framework for evaluating animal welfare that transformed both policy and practice. Its enduring influence is reflected in global adoption. However, modern welfare science has moved beyond freedom from negative states toward assessing positive welfare — opportunities for pleasure, play, curiosity, and species-appropriate satisfaction. The Five Domains model developed by David Mellor integrates this positive welfare dimension.
