Pyrenean Mastiff History: The Pyrenean Mastiff is a native of the southern slopes of the Pyrenees mountains. The Mastiff was developed in the region of the Pyrenean Mountains that stretches from Aragon to Navarra. They came with Phoenician traders from Assyria and Sumeria, originally thought to have come from the Asiatic Mastiffs. They are thought to have arrived on the Iberian Peninsula at least 30 centuries ago. In Spain they found much use as sheep guards and herders. In ancient Spain, flocks were allowed to wander the fields across political and even war boundaries in search of grass. For this, the Pyrenean Mastiff was used to guard the flocks. Only 5 Pyrenean Mastiffs per 1000 sheep were allowed. But this provided a satisfying number, as the Mastiffs are highly equipped to run off any prey that might have come along. Depending on region, the Pyrenean Mastiff was named either Mastin d'Aragon (for those from the region of Aragon), or Mastin Navarro (for those living in the region of Navarre). The Pyrenean Mastiff was at one time almost extinct but has gained new interest in recent years. Spain recovered the breed slightly with its renewed pride in Spain's Pyrenean Mastiff. Today the breed is still somewhat rare, but its numbers are much higher than previously.
