Book excerpt: 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 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.
