Created in the 1700s to assist English wardens and gamekeepers in guarding property, the Bullmastiff was bred by crossing Mastiff and Bulldog bloodlines in England. It took three entire generations of these dogs being bred in order for this breed to finally be considered "Purebred Bullmastiffs". This breed was not only intimidating with its appearance, but the Bullmastiff followed through with its physical strength and attitude. Today, the Bullmastiff is used as a companion and guard dog for families all over the world.


Strong, fearless and determined all come to mind when you view the Bullmastiff. Massive in size when it comes to every feature on this breeds body. Their head is known as a "block head", very square and large in size and should have wrinkles from the top of the head down to their deep and broad muzzle. Their ears are thick, large and triangular, they also should have slight wrinkling at the top and fold down to hang alongside of the Bullmastiff's face. This breed has a square and thick neck that flows effortlessly into their broad, very large and deep chest. The Bullmastiff is a very thick and muscular breed who has stocky and thick legs. Their front legs should be noticeably shorter than their rear legs. Males typically measure 25-27 inches in height and weigh in 110-135 pounds, while females typically measure 24-26 inches in height and weigh in around 100-120 pounds. The Bullmastiff has a short and thick coat of hair available in fawn with a black mask, brindle, or sometimes red.


The Bullmasstiff requires a firm but calm owner. This breed cannot tolerate being "yelled" at or an anxious owner. This breed is extremely loving, loyal gentle and behaved with its family. Wonderful around children if raised with them as well as the elderly. This breed also does well with other pets as long as they are raised together from the start. This breed needs an organized calmer house hold to thrive in. As always, positive reinforcement training methods are the only method recommended for the Bullmastiff. It is important that you set rules and boundaries for your Bullmastiff puppy from the start within your home so he or she can grow to know these rules and boundaries and obey your wishes. This breed surprisingly can live both in an apartment or country setting happily as long as it has enough physical exercise daily. This breed will naturally be reserved with strangers and feel the need to protect when it has to.


Regular brushing and bathe when needed. This breed does shed. It is important to check your Bullmastiff's paws on a regular basis and trim their nails due to the weight that these paws carry consistently.

Special Notes

Please fully educate yourself about this breed prior to adding one to your family to ensure the Bullmastiff is the right breed for you so you can make a life long commitment to your new addition! As always and more encouraged with large breeds as the Bullmastiff, it is highly recommended that you have a safe and properly installed fence for your new pup to roam and play safely within outdoors. Do not add this breed to your family unless you are able to provide life long physical and financial care. All dogs originate from wolves (Canis Lupus). Each breed of dog was originally created by mixing different breeds together in an effort to bring forth certain characteristics. Once a breeder has created acceptable “breed characteristics” within their bloodline and these “breed characteristics” have shown to be reliably reproduced in the offspring for three (3) generations, the bloodline may be upgraded from the category of “foundation stock” to “pure-bred”. The same “pure-bred” breed standards vary from different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders. Dog DNA testing companies can have accurate results for a specific bloodline of a small colony of dogs. However, there are tens of thousands of different bloodlines in the world which have not yet been tested for marker baseline results by Dog DNA testing companies as of 2017. For this reason Dog DNA testing companies do not guarantee the 100% accuracy of their breed lineage results and will also show different marker results for the same pure-bred breed in different continents, countries, territories, regions, breed clubs, and canine pure-breed registries depending on the goals of their breeders.
