Origins and history

The Bullmastiff is the result of a cross between the Mastiff and the Bulldog. The intention of first crossing of these two breeds was only to create fighting dogs, both powerful and flexible in nature. However, when official battles came to an end (in 1853), people realised that crossing these two breeds could create a new pure breed with good qualities. Forest rangers were particularly interested: they needed a flexible, powerful dog with a flair for fighting against poachers. Pure breed selection began in the 19th century and was perfected in the late 20th century by S. Moseley, who is considered the creator of the modern Bullmastiff.

    Description

    The Bullmastiff is a dog with a strong, symmetrical and powerful structure; but not heavy. Their head is that of a catch dog; their skull must be strong and square. The perimeter of the skull should be equal to the height at the withers. The muzzle is short: the distance between the tip of the nose and the stop is about one third of the total length of the head. The skull-face axes are convergent, and the stop is well marked. The eyes are either dark or hazel, medium-sized, set far apart and separated by a wrinkle. The ears, V shaped or folded backwards are set wide and high on the back of the head. The definition should be strong, with large, separated canine teeth. Clipping with scissors or pliers is allowed: a slightly protruding jaw is allowed but not sought after. The legs are strong and muscular.

    Good to know

    The Bullmastiff is the ideal breed for those who love big dogs but do not have enough space to accommodate a real giant. Their balanced character makes them a reliable dog in all situations, but first-time owners should beware not to be attracted solely by their magnificent physical characteristics.

    Temperament

    • 66%

      Affectionate

      The Bullmastiff is generally sweet and affectionate towards members of their adoptive family and they demonstrate a beautiful sensitivity, which allows them to feel the positivity (and also the negativity) that their owners display.

      Playful

      Despite his appearances, this dog is very happy and always ready to interact with members of his social group.

    • 33%

      Calm

      This mastiff, like many dogs of this classification, knows how to remain calm, but beneath the air of good behaviour, lies an energetic and active temperament.

    • 66%

      Intelligent

      This dog’s intelligence is reflected in their highly-appreciated versatility. For example, they have an excellent sense of smell and is therefore often used as a police dog in England. On the other hand, in the rest of Europe and in the United States, where this breed is fairly widespread, they are mainly used as a guard, companion or show dog.

      Hunter

      Hunting is clearly not this watchdog’s favourite activity, but they can, however, show interest in the pursuit of certain game.

      Fearful / wary of strangers

      Against all odds, this dog is rather sociable with strangers even though they keep a constant eye on them. Indeed, they maintain vigilance in all situations, even the most harmless.
      Moreover, this Molosser can perfectly distinguish between a new guest and an unwanted intruder. Their impressive physique is usually enough to deter impostors.

      Independent

      These big Mastiffs are totally devoted to their master. They constantly need to keep an eye on members of their social group and to please them in any way they can.

      Behaviour of the Bullmastiff

      • 33%

        Tolerates solitude

        The Bullmastiff is a true family dog that only flourishes when in company. In fact, they do not appreciate being excluded or being left alone. Thus, early learning of how to effectively manage loneliness is essential.
        They must understand that the absence of their owners is not necessarily a cause for concern. Toys should help them pass the time quickly and any absences should not be prolonged.

        Easy to train / obedience

        They are not the most docile dogs, but their desire to please their masters encourages them to be cooperative if the relationship is based on trust and mutual respect.

        A lot of patience and consistency will be needed to get the best results with this dog who, in any case, will never be a perfectly obedient dog. They will always need a little time to think before obeying their master.

        However, a clear advantage of this breed is their very good memory. In fact, everything they learn will stay with them for life.

        Moreover, given their great size, it is advised to start training as soon as the Bullmastiff puppy arrives home. Life rules and educational bases must be established quickly to prevent any bad habits setting in early.

        At first, call-back and walking on a lead without pulling will need to be acquired quickly in order to, on the one hand, keep control over this dog and, on the other hand, to ensure the walk is a pleasant experience.

        The help of a professional obedience training and behaviour is desirable.

        Barking

        Rather discreet, the Bullmastiff never barks without reason. If the dog is barking, there is a definite cause for concern.

        Tendency to run away

        The big-hearted mastiff is too protective of their family to leave home to go on any sort of adventure.
