The Rize Koyun is a landrace livestock guardian dog developed over centuries by shepherds in Turkey's Rize Province, located in the Black Sea region. It was bred to protect sheep and other livestock from predators in rugged, mountainous terrain. The breed shares ancestry with other Turkish shepherd breeds but is specifically adapted for the local climate and terrain. This regional landrace is rare and not recognized as a standardized breed by major international kennel clubs. Its development was driven by working needs rather than formal breeding programs, and its history is closely tied to the traditional pastoral practices of the area. The exact timeline of its development is not well-documented, and much of its history is based on oral tradition and practical use.
