Which instrumental figure helped establish breed standards during the Xolo's 20th-century revival?

Frances H. Hernandez

The survival of the Xoloitzcuintli into the modern era is heavily dependent on deliberate preservation efforts initiated in the early part of the twentieth century, as the breed had become critically rare following centuries of neglect after the colonial period. A key individual instrumental in this process was Frances H. Hernandez. Her work involved the critical tasks of collecting, promoting, and meticulously documenting the remaining dogs scattered across remote areas. This foundational documentation and promotion were vital steps that eventually led to the establishment of the first official breed standards for the Xoloitzcuintli, setting the foundation for its eventual official recognition by organizations like the American Kennel Club.
