A transboundary breed is a breed which is present in several countries, compared to a local breed which is present in just one country. A regional transboundary breed is one that occurs only in one of the seven SoW-AnGR regions—Africa, Asia, Europe and the Caucases, Latin America and the Caribbean, Near and Middle East, North America, and South West Pacific. An international transboundary breed is one that occurs in more than one region.
