Despite being a single species, dogs represent nearly 400 breeds with substantial genetic, morphological and behavioural diversity. In this Review, Ostranderet al. discuss how genomics studies of dogs have enhanced our understanding of dog and human population history, the desired and unintended consequences of trait-based selective breeding, and potentially human-applicable insights into cancer, ageing, behaviour and neurological diseases.
