Like most dog breeds developed in the Americas, the dogo argentino descends from dogs brought from Europe during the colonial era. In contrast, the Xoloitzcuintli is among a handful of breeds that descend from non-European populations that predated colonization. In 2013, researchers added another breed to this list: the Carolina dog, which is native to rural pockets of the Southeastern US. This breed has a unique genetic link to East Asian populations that were themselves the ancestors of the precolonial dogs of the Americas.
