Hegoalde
Many opinions exist on the origins of the Pottok. It is deemed by the scientific community to have lived in the area for at least several thousand years. It displays signs of genetic isolation and is genetically closest to breeds like the Asturcón, the Losino, the Galician, the Landais, and the Monchino horses. Tests have revealed considerable genetic differences between populations in the Northern Basque Country and the Southern Basque Country, leading some to consider them separate breeds.
