About the Spanish Mastiff

The Spanish Mastiff, or Mastin Espanol, is a giant and powerful livestock guardian breed with a history spanning over 2,000 years on the Iberian Peninsula. Originally bred to protect Merino sheep flocks from wolves during long seasonal migrations, the Spanish Mastiff is one of the largest dog breeds in the world, with males reaching up to 200 pounds. Their massive head, thick loose skin, and deep bark make them formidable guardians with a surprisingly gentle temperament.
