Temperament of the Pyrenean Mastiff

Faithful, calm, affectionate and very noble, the Pyrenean Mastiff is an excellent guardian. His origins as a herdsman are part of his character, and remain today the foundation of the breed's aptitudes.

Fierce and courageous, he is not really aggressive, but he will be a formidable opponent if forced to be so.

Hypersensitive, but stubborn nonetheless, firmness without aggressiveness must be integrated into his education. Very well balanced in his natural environment, he will be totally destabilized outside his domain.

History of this breed

The origins of the Pyrenean Mastiff, though little known, are believed to be very ancient.

Like most molossus, the Pyrenean Mastiff is probably descended from the ancient Assyrian molossus or the Tibetan Mastiff.

This large dog was widely used in the mountains of Navarre and Aragon to guard and protect sheep against attacks, especially from bears and wolves.

The breed almost became extinct around 1939. It was saved from extinction by the few farmers who kept the Pyrenean Mastiff as a protector of their farm.

These few specimens were used for the reproduction of the breed around the seventies. It is in 1946 that a first standard was created but it was later revised in 1982.

This magnificent guardian is first and foremost a great protector. Bred to protect sheep, his natural instinct is innate, even though he is used as a companion dog nowadays. He remains an excellent guardian as well as an endearing companion dog.
