The Animal Welfare Act 2006 transformed UK companion animal welfare law by creating a positive duty of care, making welfare failures illegal before suffering occurs.
The Animal Welfare Act's positive duty of care represents a philosophical shift from reactive to preventive welfare law: owners can now be prosecuted for failing to meet welfare needs before an animal suffers, rather than only after suffering is documented. The improvement notice system allows welfare to be improved without prosecution. The 2021 increase in maximum penalties signals increasing societal seriousness about animal welfare as a legal obligation. The Act has enabled prosecutions and interventions that prevent suffering that would previously have been legally unaddressable.
