About the Spanish Mastiff
The Spanish Mastiff, or Mastin Espanol, is a very large guardian breed from Spain, traditionally used to protect flocks from wolves, often accompanying migrating sheep. It is powerful and heavy-boned with a broad head, loose skin about the neck and a deep chest. The coat is of medium length and comes in various colours, including fawn, brindle and black.
Temperament
Calm, dignified and protective, often aloof with strangers. It is generally gentle with its own family but needs early socialisation and calm, firm handling because of its size and guarding instincts.
Exercise
Moderate daily exercise suits it, such as steady walks and time in a secure garden. Avoid hard, repetitive exercise in young dogs while the bones are developing.
Grooming
Medium-length coat that benefits from brushing once or twice a week, more in the moult. Keep skin folds around the neck clean and dry.
Care & wellbeing
As a giant breed, weight control and careful growth matter for the joints. Provide shade in warm weather and check the ears and skin folds.
