Description

The Spanish Mastiff (Mastín Español) is a majestic and powerful livestock guardian from Spain, historically used to protect flocks from predators like wolves. These dogs are calm, courageous, and extremely loyal, often forming a deep bond with their family and territory.

Their short, dense coat sheds heavily, particularly during seasonal changes, and benefits from regular brushing to manage fur and skin health. While highly intelligent, they are independent thinkers, which means training must be firm, consistent, and respectful—they don't respond well to harsh methods or excessive repetition.
