Simple Summary: This article emphasizes the importance of educating veterinarians and veterinary students in animal welfare science and veterinary ethics, so that they can ably advance pertinent scientific knowledge and promote ethical thinking as trusted animal advocates in the 2020s. In light of this public expectation, a number of challenges are raised for veterinarians and the veterinary profession. These challenges involve: (1) re-envisioning the nature of disease treatment that goes beyond traditional conceptions of health or clinical matters, and which include animal welfare; (2) re-imagining disease prevention at the intersection of animal-human-ecosystem health;(3) developing core competencies in animal welfare science and ethics in order to provide professional leadership in animal welfare; and (4) taking a more active role in the development of novel networked devices, monitoring technologies and automated animal welfare solutions, and understanding their effects on the welfare of animals, human-animal relationships, and the veterinary profession in general.Abstract: What should leading discourses and innovation regarding animal welfare look like for the veterinary profession in the 2020s? This essay considers four main challenges into which veterinarians are increasingly being drawn, as they respond to increasing public expectation for them to be scientific and moral authorities in animal welfare in addition to their traditional role as trusted health experts. They include: (1) to go beyond traditional conceptions of health by adopting a holistic view that also considers animal welfare, not only disease treatment; (2) to reimagine their professional duties when it comes to disease prevention at the intersection of animal-human-ecosystem health; (3) to develop core competencies/proficiency in animal welfare science and ethics in order to navigate discourses concerning competing priorities and socio-political ideologies and to provide professional leadership in animal welfare; (4) to provide feedback on novel networked devices, monitoring technologies and automated animal welfare solutions and their impact on animals' welfare. To competently navigate the intricacies of the socio-political and connected world as trusted authorities and conduits for innovation in and through animal welfare, veterinarians and veterinary students are encouraged to: (a) develop core competencies in veterinary ethics, animal welfare science and deliberative capacities that are well-informed by current multidisciplinary frameworks, such as One Health; (b) engage interested parties in more effective collaboration and ethical decision-making in order to address animal welfare related concerns within their immediate sphere of influence (e.g., in a given community); and (c) participate in the process of engineering and technological design that incorporates animals' welfare data (such as their preferences) for real-time animal monitoring through adding animal scientific and values-aware evidence in information technology systems. ...
