Breed Details


The Spanish Mastiff is the largest dog breed of Spain and is also known as Mast�n Espanol, Mast�n de Espana, Mastin de la Mancha, Mastin de Extremadura and Mastin de Leon. It is believed to be the Largest Guardien Dog (LGD) breed in the world. This mountain type dog was developed from ancient molossus dogs that accompanied Alexender the Great throughout Europe. Originated from Estramadura region some 2000 years B.C, this ferocious live stock guardian was once used to hunt wild boar and also as war dog but its prime responsibility always remains guarding the flock from wolves, bears and other predators.

The Spanish Mastiff is a powerful dog and is called Masten de Leon as this mastiff among dog breeds is what the Lion is among ferel animals. It makes the great defender of the sheep and formidable and worst enemy of wolves and other predators. There are two types of Spanish Mastiff – the Mastin Pesado and Mastin Lagero. The Mastin Pesado is the heavier type Spanish Mountain with a more impressive appearance and it is found in mountain areas of Spain while the Mastin Lagero is the lighter and more athletic, agile and faster breed that is found in Andalusia, Meseta and in other regions south of Spain. Generally, the Spanish Mastiff stands atleast 30 inches and weighs about 140 to 175 lbs.

This well balanced and well boned breed comes with a big, massive and pyramid shaped head with typical mastiff loose fold skin, broad and strong skull and rectangular muzzle. Wet, big and wide nose is black in colour. Hazel colour, almond shaped eyes have soft, noble and intelligent expression which can change to stern gaze in front of strangers. Triangular shaped, flat and hanging ears are attached above eye line. The neck is broad and solid. Massive body is rectangular in shape and comes with straight topline, powerful and muscled back, long, broad and powerful loin and deep, broad and well muscled chest with rounded ribs. Medium length, dense coat is equally distributed all over the body and is preferred in yellow, fawn, red, black and wolf colour.

This breed is NOT recognized by AKC however it is recognized by FCI.


The Spanish Mastiff can come in any color but most preferred coloring for this breed are yellow, fawn, red, black, wolf-color and deer-color, brindled or particolored. Also, dogs with white collars are more appreciated.


The Spanish Mastiff has medium length, thick and smooth coat with a dense undercoat. The coat is shorter on legs and longer, silkier on tail.


The Spanish Mastiff is a massive self-assured breed that is well aware of its enormous power. This dog is a fierce protector of its family and possession. It is affectionate and gentle with its family including children but wary of strangers. This breed is very courageous and brave. Though the dog may appear disinterested and lazy, it can jump into action in a fraction of a second to unleash its enormous power to counter tackle any perceived threat. This devoted dog would not back away against any kind of threat. It makes an excellent guard and watch dog. The Spanish Mastiff is loving to its family although it is not a very demonstrative breed. It is aggressive towards other dogs and leery of strangers. Obedience training and socialization from young age are most important for this breed to curb its aggressive attitude towards other dogs and make it a well rounded family pet.


Otherwise a light shedder, the Spanish Mastiff sheds heavily during fall and summer and would need to be brushed more often then once a week to remove dead hair. This relatively inactive breed does not get dirty quickly due to low activity levels.


Obedience training and early age socialization are important for this breed to accustom the dog with different situations, people, places and dogs. Positive and reward based training will get the best out of this dog.


This dog has average exercise requirements and if provided with a largish yard, it will not need to be taken on daily walks as the dog will let out its energy by playing and running. Assigning guarding role will also help this breed expel its energy.
