A mix of the purebred Bulldog and purebred English Mastiff, the Bullmastiff is a loyal, brave, and affectionate dog breed. In this article, you’ll learn every reason there is to take home and love a purebred Bullmastiff puppy!  


This breed came onto the scene in the mid 19th century as a response to a plague of poaching. At the time, poachers were known to ransack English country estates and game preserves owned by wealthy aristocrats in England. Making off with their valuables. There were laws in place to dissuade poachers from robbing valuable game from these estates. But the penalty was death by hanging. This only motivated the poachers to kill in order not to be caught or reported by witnesses. Several guard dog breeds were tried as a protection and alarm system on these estates. But it was only the Bullmastiff that succeeded.

The sheer size and fearless nature of the Bullmastiff gave this breed the edge. Intelligent and discerning, the Bullmastiff had the ability to “capture and pin” poachers. By exercising the self-restraint not to kill them, the Bullmastiff dog breed was soon employed at virtually all English estates. By 1924, the Bullmastiff was hailed as a competition show dog in England’s Kennel Club, since breeders had perfected this guard dog for the purposes of supplying the best of the best to gamekeepers. The reliability and popularity of the Bullmastiff soon “crossed the pond” and this breed was recognized by the American Kennel Club, which led to home and business owners as well as gamekeepers using Bullmastiffs for protection and companionship.

The Bullmastiff is a large dog breed from the “working group” category of purebred dogs. Tall and muscular, the males of this breed can weigh as much as 130 lbs. And the females weigh in at 100 – 120 lbs. They have a short, smooth, double-layer coat of fur. This can be either fawn, brindle, or red, or a combination of these colors. Most notably, this breed has a large, square head and blunt snout that can resemble the Boxer dog breed. All Bullmastiffs regardless of their fur colors have a standard black “mask” of fur on their faces. The life expectancy of this courageous yet docile breed is 7 – 9 years. The Bullmastiff should not be confused with its larger cousin, the English Mastiff. A famous English Mastiff you might remember starred in the 1993 coming-of-age blockbuster movie, The Sandlot.

Bullmastiffs are exceptional guard dogs. This speaks to their loyal, protective nature towards their human family. And their courageous, fearless confidence with strangers. This should be taken into account during the puppy training and socialization process. Bullmastiff owners fall into error when they assume that their sweet-natured giant will behave that way towards everyone

Bullmastiffs regard their families versus unknown people very differently. And this instinct of theirs is highly pronounced when their owners do not carefully train their Bullmastiff puppies right away. When you bring a Bullmastiff home, you’re getting a guard dog first and foremost. Bullmastiffs instinctually protect their families and homes. Focus puppy training your Bullmastiff to regard new people. And to proceed with a welcoming, friendly attitude towards new people, unknown children, and animals both domestic and wild.  

While your puppy will naturally regard unknown people and strangers as potential threats, and proceed in a “guard dog” manner, you and your family will experience the true heart of the Bullmastiff breed. Towards you and your family, your Bullmastiff will be gentle, docile, affectionate, and companionable. Many owners of this majestic breed describe their dogs as loyal, obedient, and nurturing. They are eager to please and playful with a bouncy energy whenever they’re on an outing with their favorite person.

The Bullmastiff is delightfully paradoxical. Gentle yet aggressive. Docile yet energetic. There is the “family” side of this breed’s personality that greatly contrasts its “guard dog” nature. This aggressive side comes out during times of conflict and confrontation. In the same vein, you will quickly notice your Bullmastiff is highly energetic at times. This breed has agility and inexhaustible strength. While hanging out around the home, your Bullmastiff will be docile. He’ll hardly lift his giant head to see which family member just went into the kitchen. 

Your Bullmastiff needs 1-hour of exercise per day. This is in addition to his bathroom trips and walks around the block in the early morning and early evening. When walking in public areas, your Bullmastiff should remain on his leash. Only allow him outside off leash on your own property if your boundary lines are fenced in. If your home property does not have a fence, we recommend you install one. Bullmastiffs act aggressively towards strange people and animals that walk near or on the property. A fence will prevent any mishaps.

When bringing your Bullmastiff to the dog park, we advise that you proceed with caution. Until your Bullmastiff is trained and obedient to you, we don’t recommend letting him off leash at a dog park. Only the owner of a Bullmastiff will know the dog’s exact personality and temperament. And so please use your best judgment when you’re deciding whether or not your Bullmastiff is ready for the park. 


Though the Bullmastiff has a short coat of fur, this breed sheds year-round and requires regular brushing. You can keep shedding under control by brushing your Bullmastiff either once a day or once every three days. We also advise that you socialize your Bullmastiff during puppyhood. Bring him to the professional dog groomers. He will be “handled” and groomed by “strangers.” This will help train your Bullmastiff to accept being touched and handled by appropriate people. And will broaden his understanding of “safe places” where he doesn’t need to “have his guard up.”

Owners of Bullmastiffs should pay special attention to their dogs’ coats. If the coat becomes dry or oily, take your dog to see the vet regarding an underlying health problem. If this occurs, bring your Bullmastiff to see the vet for proper diagnosis and possible treatment.

To conclude this blog, we have to take a moment to rave about the joys you’ll experience owning a Bullmastiff. Your Bullmastiff’s unique personality will warm your heart. Every quirk, from his hilariously loud snoring to his almost saintly self-restraint from barking will endear him to you! The gentle attitude and docile demeanor of your Bullmastiff around the home will make a wonderful housemate and furry friend. This breed also provides you and your family with a sense of security and protection.
