Temperament of the Bullmastiff

Do not be fooled by his sad old man look because he is a dog who loves to play, cuddle and be cared for by everyone.

Courageous and very strong, the Bullmastiff has a very gentle character despite his temperamental air.

He is an ideal dog for all family members, including young children. The only problem with this breed for young children is simply that he is not aware of his size.

Endowed with an excellent sense of smell and great strength, he is very appreciated as a police dog.

However, due to his very gentle temperament, he is equally appreciated as a family member and life companion.

Despite his large size, when he is indoors and everyone is there, he will follow the rhythm of the household without any problem and will not take up any more space than any other dog.

The Bullmastiff is not athletic at heart and even if he loves to take part in games, he will quickly run out of breath and will soon prefer the position of spectator to that of participant.

He likes to go for walks but also likes to return so he can have a quiet nap.

Tips About this breed

Despite his appearance as a vicious guard dog, the Bullmastiff has a vital need for human contact. He can be used in the yard as a guard dog as long as he can go indoors and enjoy the presence of his masters regularly.

He does not have the temperament of a guard dog, but his gait alone gives him an impressive look and is enough to repel any prowlers.

This fabulous dog is ideal for masters who love molossus but do not have the space needed for giant dogs.

The Bullmastiff will make do with the space allotted to him. He can make himself very little and live in a small space.

He'll be very happy there as long as he's not left alone. Human contact is essential to his happiness and mental balance.

Well surrounded, he will be well balanced and happy and will be the best companion in life.

Health of the Bullmastiff

The Bullmastiff is incredibly strong and sturdy and is in excellent health.

However, since he likes to eat, or rather, devour, it is preferable to monitor his diet in order to prevent him from becoming overweight.

It is important to watch out for hot days to not exhaust him. In spite of his very massive structure, he exhausts himself very easily.

Daily walks are good for the Bullmastiff, but too much exercise is not recommended.


The coat is very short, so the Bullmastiff does not require any special care.

Regular brushing will please him and help him get rid of superfluous hair, but it is not necessary to do more than standard maintenance for all dog breeds without special requirements.

History of this breed

This dog of British origin was the result of a cross between the Bulldog and the Mastiff. Originally created for dog fights, the Bullmastiff breed produced dogs that were both flexible and powerful at the same time.

However, at that time and following the abolition of official dog fights around 1853, rangers began to take a great interest in the breed.

The quality of the crossbreeding produced dogs with outstanding qualities, a great sense of smell and a flexibility that was essential in the fight against poachers.

The breed began around the 19th century but was perfected towards the end of the century by the father of the modern Bullmastiff, S.S. Moseley.

The Bullmastiff was therefore used as a dog for game rangers, but since he was able to tackle a human being to the ground and keep him there until the next command, he was also adopted as a police dog.

In Great Britain, in 1920, the first Bullmastiff club was created.

He was officially recognized around 1924 and almost disappeared during the Second World War, but the breed resisted.
