Whilst a Western Australian veterinary student in 2000, I caused great controversy by refusing to kill animals during my surgical and preclinical training. Instead, I helped establish a humane surgical training program, based partly on neutering homeless animals from animal shelters. I’m now a Veterinary Professor of Animal Welfare. After teaching at Ross University School of Veterinary Medicine from 2013-2014 I established a Centre for Animal Welfare and two animal welfare degrees at the University of Winchester (UK) in 2015. I left in 2023 to establish my own UK-based nonprofit organisations Representing Animals and the Sustainable Pet Food Foundation, and I now do animal welfare research and outreach full-time. I’m also an Adjunct Professor at Murdoch University veterinary school, Western Australia (one of Australia’s leading veterinary schools), and in the School of Environment and Science at Griffith University, Queensland, and am a Visiting Research Fellow at the University of Winchester, UK. I’m an internationally accredited Veterinary Specialist in Animal Welfare; a Fellow of the Royal College of Veterinary Surgeons, and a Principal Fellow of Advance HE. I have many publications, websites, and social media videos on animal welfare issues, which have attracted numerous awards. My books include The Costs and Benefits of Animal Experiments (2011), and (as Editor) the Routledge Handbook of Animal Welfare (2023). The latter summarises all main animal welfare issues, and key animal law in all major world regions. It’s available fully open access via www.aknight.info/aw-book, and its chapters have been downloaded well over 200,000 times to date, making it one of the world’s leading animal welfare textbooks. It has been described as a “new bible for the animal advocacy movement.”
