All of the veterinary schools in Australia and New Zealand worked together to develop the online One Welfare learning and teaching portal (OWP) for sharing teaching resources to assist veterinary graduates to become leaders in animal welfare and ethics (AWE). The materials in the portal are organised around eight key themes including two overarching themes of animal ethics and animal welfare science, and six context-specific themes: companion animals; animals used in research and teaching; livestock/production animals; animals used for sport, recreation or display; animals in the wild, and aquatic animals. The arrangement of these resources aligns with those of the Australian Animal Welfare Strategy (AAWS). As part of the OWP development, animal welfare educators from the eight veterinary schools met and used modified deliberative polling to prioritise resource development. Surveys of students and educators in all participating schools investigated their attitudes to current AWE issues across six context-specific themes: companion animals; animals used in research and teaching; livestock/production animals; animals used for sport, recreation or display; animals in the wild and aquatic animals. The prioritised resources include (1) student AWE essays arranged by subject; (2) an online reflection tool that can be used repeatedly to gain understanding of change in attitudes over time; (3) eight overarching themes that host a group of interactive scenarios; (4) research papers for each context-specific theme; (5) a bank of multiple choice questions with feedback to support AWE assessment; (6) a novel online discussion tool ‘Chatterbox;’ and (7) a ‘toolbox’ containing directions to the doglogbook, an owner app designed to monitor management practices, and evaluate quality of life in dogs.
