The Spanish Mastiff's history is deeply intertwined with the pastoral traditions of Spain. For centuries, these dogs have been used by shepherds to protect livestock, particularly sheep, from wolves and other predators. Their lineage is ancient, likely descending from Molosser-type dogs brought to the Iberian Peninsula by the Romans or Greeks. The breed played a crucial role in the transhumance, the seasonal movement of livestock, traveling alongside the flocks and guarding them on their journeys. The Mesta, a powerful association of sheep ranchers in medieval Spain, greatly influenced the breed's development and standardization. The Spanish Mastiff was officially recognized by the FCI (Fédération Cynologique Internationale) in 1946, and standards were established to preserve its unique characteristics.

When properly socialized and raised with children, Spanish Mastiffs can be gentle and tolerant. However, due to their size, supervision is always necessary.
