Where it comes from
Origins of the Pyrenean Mastiff
High summer pastures in the Spanish Pyrenees exposed flocks to wolves and bears, and shepherds needed an enormous, thick-coated dog able to withstand harsh mountain weather while confronting large predators. The breed's bulk, heavy coat and calm vigilance suited a life spent largely alone with the flock at altitude.

The long read
About the breed
Its mountain guardian role demanded a heavy, weatherproof coat, great size and an independent, watchful temperament capable of working unsupervised for long periods.
With its family it is affectionate, patient and notably gentle, especially with children, though it retains a strong protective instinct and can be reserved with strangers until properly introduced.
Still used to guard flocks in parts of Spain, the breed has also gained a following as a calm, devoted giant companion for owners able to provide the space it needs.

Point 1
Skull
The Pyrenean Mastiff's skull is judged on balance rather than size — proportionate to the body, with a clean cheek and a stop typical of the breed. Coarseness or an over-refined head are both faulted.
