Bridging the gap between the science of animal welfare and the animals and their owners, this book gives essential advice to practitioners worldwide on how to improve the welfare of all animals. Down to earth and intensely practical, the book describes the fundamentals of changing human behaviour to benefit animal welfare and how this can be applied in real life situations. This book contains: - voices from international experts and those working on the ground, on challenges presented and overcome;- advice on making change happen in practice, by influencing animal owners, users or communities, and the systems they are part of;- the work and life experience of animal welfare practitioners, as a profession;- essential information on how to translate the science of animal welfare and human behaviour change into real life for maximum impact;- resources to use from low-, middle- and high-income countries, e.g. case studies, influencing skills, best practice, hints and tips.This is an important text for animal welfare advisors, researchers, welfare auditors and veterinarians, and key reading for all those concerned with animal welfare in non-governmental organisations, in governments, in industry and at universities.
