Pyrenean Mastiff

The Pyrenean Mastiff is a big Spanish dog bred to guard livestock in the Pyrenees mountains. These gentle giants once protected sheep during seasonal migrations to high pastures. They're a separate breed from other mountain dogs like the Pyrenean Mountain Dog.

• Originated in Aragón, a region in northeastern Spain.
• Historically protected flocks during summer mountain migrations.
• Not the same as the Spanish Mastiff or Pyrenean Mountain Dog.
