History of the breed

The Mastiff has been a symbol of valor for millennia . Some stories relating to its origin date back more than 2,500 years. But the most common dates back to the year 55 BC , when Caesar and his troops invaded England . His legions were then forced to face mastiffs whose first type sported an aspect close to the BullMastiff, while the second species would have presented the typical physiognomy of the Mastiff. The power of this second race, unknown to the Romans, made their own mastiffs seem like simple pet dogs.

Once the British Isles were conquered, Caesar’s legions decided to take these war machines with them. They turned them into circus and fighting animals that had to face even more ferocious elephants and animals. It was these exceptionally strong dogs that created the breed known today as the Mastiff.

Like many dogs, the Mastiff breed nearly died out during WWII, but it survived. These exceptionally hardworking and courageous dogs are still popular as ever. The Fédération Cynologique Internationale recognized the breed on November 5, 1964.

Behind the imposing appearance of the Mastiff hides a sentimental dog . Which makes him an excellent companion . Moreover, he does not bind affection for a particular person, but for the whole family who adopted him. Easy going , he appreciates displays of affection. This does not prevent him from having the typical aggressiveness of a good guard dog if he feels a danger for his masters. Above all, he uses his dissuasive physique to ward off intruders even if he is most of the time indifferent to their presence. He is delicate and playful with the children whom he will supervise with the greatest rigor.

The Mastiff
is it right for you?
Take the test!



The Mastiff is not really known for its docility. It is therefore necessary to instill good manners from an early age. In addition, dogs of this breed are not always aware of their power . Better that they get used to the leash early enough, so that even children can hold them from time to time. His master will have to be sure of himself, full of confidence. He has to be both bossy and gentle to get what he is looking for. Thus, the positive method is the best to achieve convincing results.

Living conditions

Suitable for apartment living
Good for new masters
Love it hot
Love the cold

Due to its large size, it is difficult for the Mastiff to live in an apartment . He needs a large garden to stretch his legs and allow him to move around as he pleases without committing massacres. A house in the countryside will be the ideal place to welcome it in a beautiful family atmosphere. The Mastiff also does not like travel. He prefers to remain lying quietly in front of a fireplace and in the company of his master.


Ease of gaining weight

Despite its undeniable physical strength, the Mastiff is quite delicate during the first years of its life . Its bones are particularly fragile during the growth phase, but it gains a little more strength over the years. The Mastiff’s lifespan rarely goes beyond 11 years. The breed having almost disappeared on several occasions, its safeguard could be done by a difficult work of consanguinity . This is why his life expectancy is only 11 years .

The Mastiff, like all large dog breeds, can be prone to stomach twisting . It is therefore advisable to give him a diet adapted to his morphology and his rhythm of life.
