Abstract: The phenotypic and behavioral diversity of the domestic dog has yet to be matched by any other mammalian species. In their current form, which comprises more than 350 populations known as breeds, there is a size range of two orders of magnitude and morphological features reminiscent of not only different species but also different phylogenetic families. The range of both appearance and behavior found in the dog is the product of millennia of human interference, and though humans created the diversity, it remains a point of fascination to both lay and scientific communities. In this review, we summarize the current understanding of the history of dog domestication based on molecular data. We examine the ways that canine genetic and genomic studies have evolved and look at examples of dog genetics in the light of human disease.
