Temperament of the Spanish Mastiff

This guardian at heart has a loving, balanced and very calm character. He becomes fearsome when his master or his property is in danger. As the reconstitution of the breed is not yet fully developed, some subjects are more aggressive, while others are a little too reserved compared to their large size.

Balanced but sometimes stubborn, he needs an iron fist in a velvet glove. His education must be firm and strict and hierarchy must be instilled in him at a very young age.

This magnificent dog has many qualities as life companion, but he must absolutely be monitored by an experienced master because he is endowed with a strong character and a rather stubborn temperament, often making him reluctant to be submissive.

Tips About this breed

His stubbornness must be firmly controlled at an early age, through very strict education. His place in the family must also be instilled early so that he knows where he stands in the family hierarchy.

He can live outdoors, but it is essential that he has an adequate shelter for protection. Despite his fur and robustness, this large hound can suffer from the cold.

Obviously, an apartment in the city is not ideal for him. He needs space and fresh air, but the master needs to be close by because human contact is also essential for him.

Health of the Spanish Mastiff

The Spanish Mastiff, rather robust once adult, requires increased surveillance during his growth, as do all molossus.

Food with a high percentage of protein is necessary, as he remains quite delicate throughout his growth. No pathology affects the breed.


A regular brushing is necessary for the maintenance of his beautiful fur. However, no other special maintenance is required.

History of this breed

This large hound, which originated in a region of Southwestern Spain, more precisely in Extremadura, is apparently the oldest Spanish dog breed.

Directly descended from the Molossus of Tibet, imported by the Romans, the Spanish Mastiff was used to protect livestock for centuries. Shepherds often had to move flocks of sheep to very remote areas, and with the Spanish Mastiff, shepherds and their flocks were protected and very well guarded.

The activities of the shepherds having practically disappeared in modern times, this big hound lost his popularity and almost disappeared completely. The breed is still in breeding.

The first standard of the Spanish Mastiff was established in 1946, but the club did not officially come into existence until 1981. Used at that time to guard herds, he is appreciated nowadays as a life companion, but his main skills remain guarding and protecting people and their property.
