The history of the Bullmastiff can be traced back hundreds of years despite only being registered as purebred in the early 1920’s. The breed was developed to accompany the English Gamekeeper who patrolled the Royal Game reserves to prevent poachers from stealing the monarch’s “game” animals. In those days poaching was punishable by death and anyone caught was expected to put up a fierce fight and many Gamekeepers were seriously injured or killed. A powerful and fearless animal was sought to not only dispatch the poacher’s dogs but also to knock down and hold the poacher until his master arrived to affect an arrest.

Gamekeepers sought a brave, faithful dog who would cope with the rigours of long patrols but also the frequent battle at the end. Primarily a cross of the old style English Mastiff and Bulldog was used as these were very formidable and athletic dogs at the time. This cross had been in existence for many hundreds of years and there is still debate if the Mastiff and Bulldog are distinct breeds or just varieties of the one animal. A few other breeds were also introduced as working ability was more highly prized than maintaining pure blood. 

In the early 1920’s Gamekeepers held shows to parade their cross bred “Night dogs” and within a few generations they were accepted by the UK kennel Club as pure bred. The “Farcroft” kennels bred many of the early winners and their long legs, moderate bone and height and healthy muzzle length was  a result of the fact that they were often working Gamekeepers dogs by night and show dogs by day.   

The breed saw a huge surge in popularity but slowed partially during the first and second world wars before the famous “Bulmas” kennels come to the fore. “Bulmas” kennels developed a bulkier, stronger headed animal that was to become a model for modern day Bullmastiffs. It was in fact a “Bulmas” dog that was the first Bullmastiff to be exported to Australia and after a quiet start the breed established a dedicated following.

The Bullmastiff Club of New South Wales was established in 1988 and 2018 saw us celebrate our 30th Anniversary at the September Championship show Judged by Chris Quantrill from the UK.

The modern Bullmastiff is a large and powerful animal whose formidable appearance disguises his loyal, loving and humorous nature. The sharp temperament of the original dogs has mellowed somewhat but even the most laid back character can be protective when provoked. Should you be looking for a family guardian whose love for children is well known then the breed may be ideal. The breed can also be stubborn and requires proper socialisation to become a well mannered member of the family.

Males should grow between 25 and 27 inches tall and weigh between 50- 59 kilograms, with females an inch shorter and 10 kilograms lighter than these limits. The breed should be compact, well balanced and powerful without being cumbersome. The head is important for type and should be square in appearance with a square muzzle. The bite is undershot or level preferred but judges need to remember the Bulldog heritage before penalising slightly undershot animals too harshly.

The breed comes in three colours described as red, fawn and brindle, all with a distinctive facial mask. This mask defines expression with a black muzzle, black areas around the eyes and small ears that are slightly darker than the coat colour.

The breed is incredibly quiet and rarely makes a noise without provocation and persistent barking should be investigated. They require periodic grooming if kept inside as they can shed a little but the coat is generally care free. They require moderate exercise and are happy lazing around and sleeping on the lounge. Apart from the lounge, one the breed’s favourite position is next to their master and even sitting directly upon their feet. They don’t eat a huge amount considering their large size and care should be made to keep puppies lean in growing periods to prevent skeletal disease.

As with most large breeds they are generally not long lived and while ages in double figures do occur they are most likely to reach 7-8 years of age. Bone cancer and Lymphatic cancers can often affect the breed and in fact Lymphatic cancer heavily contributes to premature death. They can suffer from hip and elbow problems but since it is compulsory to score before breeding, all puppy buyers should be able to view these health reports and make an informed decision. The breed can sometimes suffer allergies and eye problems such at entropion.

The breed is incredibly dedicated to family and if you are after an imposing dog to deter would be thieves without being overly active and noisy then the breed could suit your needs.
