The Great Pyrenees carries several names across different regions, each reflecting their geographic origins and historical roles. In the United Kingdom and throughout most of Continental Europe, the breed is officially known as the Pyrenean Mountain Dog, emphasizing their mountain heritage. This nomenclature appears in breed standards maintained by The Kennel Club of Great Britain and various European kennel organizations, maintaining consistency with continental naming conventions.
In their native France, the breed holds multiple French designations reflecting their cultural significance. The formal French name is Chien de Montagne des Pyrénées, which translates directly to Dog of the Pyrenees Mountains. More colloquially, French speakers often use the abbreviated form Chien des Pyrénées. Another common French nickname is Patou, used primarily by shepherds and rural communities in the Pyrenees region where the breed continues working as livestock guardians.
The American designation Great Pyrenees became established when the breed arrived in the United States during the 1930s. American fanciers chose this name over the European Pyrenean Mountain Dog designation, creating the nomenclature used by the American Kennel Club since the breed's official recognition in 1933. This American naming convention has been adopted by the Canadian Kennel Club and other organizations in North America, creating a distinct American identity for the breed while maintaining recognition of their Pyrenean origins.
Histoically, the breed enjoyed royal patronage that led to the designation Royal Dog of France. In 1675, King Louis XIV officially declared the Great Pyrenees the royal dog after Madame de Maintenon and the Dauphin brought specimens to court. This royal recognition elevated the breed's status throughout France, with nobility adopting them as estate guardians and prestigious companions. The royal designation reflected the breed's impressive appearance, noble bearing, and effectiveness as protectors of châteaux and estates.
The breed's various names often reference their primary historical function as livestock guardians. Terms emphasizing their mountain origins acknowledge the harsh Pyrenean environment that shaped their development. The steep, rocky terrain between France and Spain created dogs with specific physical and temperamental characteristics suited for independent work in challenging conditions. Their thick white coats provided insulation against cold mountain weather while allowing them to blend with sheep flocks, approaching predators with surprise advantage.
Some regional variations in naming exist within the Pyrenees themselves, with local shepherds using descriptive terms in various languages and dialects. Basque shepherds, whose ancestors helped develop the breed over millennia, maintain their own terminology for these dogs. Spanish shepherds in the southern Pyrenees sometimes use variations of Spanish names, though the distinct Pyrenean Mastiff breed exists on the Spanish side of the mountains as a separate entity.
Breed recognition varies slightly across international kennel organizations regarding breed standards and allowed characteristics. The Fédération Cynologique Internationale (FCI), which governs breed standards for 91 member countries, recognizes the breed as Chien de Montagne des Pyrénées under their classification system. The FCI standard group includes the breed within Group 2, Section 2.2, covering Molossoid breeds and Mountain Dogs. This international recognition ensures breed consistency across much of Europe, South America, and Asia, where FCI standards determine show eligibility and breeding requirements.
The breed sometimes appears in historical documents under descriptive names rather than formal breed designations. Medieval French writings from the 1400s reference Great Dogs of the Mountains serving as château guardians, clearly describing dogs matching the Great Pyrenees type. These historical references demonstrate the breed's long-established presence in the Pyrenees region, though formal breed naming and standardization didn't occur until much later during the organized dog fancy movement of the late 1800s and early 1900s.
Naming confusion occasionally arises between the Great Pyrenees and other large white livestock guardian breeds including the Maremma Sheepdog, Kuvasz, and Akbash. While these breeds share similar coloring, size, and guardian functions due to parallel development as mountain flock guardians, they represent distinct breeds with separate origins and breed standards. The Great Pyrenees distinguishes itself through specific head type, tail carriage, double dewclaws on rear legs, and breed-specific movement and temperament characteristics that experienced fanciers easily identify.
