Do dogs belong with humans? Scientific accounts of dogs' 'species story,' in which contemporary dog-human relations are naturalised with reference to dogs' evolutionary becoming, suggest that they do. Dog politics dissects this story. This book offers a rich empirical analysis and critique of the development and consolidation of dogs' species story in science, asking what evidence exists to support it, and what practical consequences, for dogs, follow from it. It explores how this story is woven into broader scientific shifts in understandings of species, animals, and animal behaviours, and how such shifts were informed by and informed transformative political events, including slavery and colonialism, the Second World War and its aftermath, and the emergence of anti-racist movements in the twentieth and twenty-first centuries. The book pays particular attention to how species-thinking bears on 'race,' racism, and individuals.
