Breed Overview

The admixture of mastiff and bulldog breeds birthed a protective and imposing dog known for its loyal and gentle nature with family members. Dubbed the "Gamekeeper's Night Dog," this breed was originally bred to deter poachers in England during the 19th century. Bullmastiffs are renowned for their courageous and fearless demeanor, making them excellent guard dogs while maintaining a loving and affectionate temperament towards their human companions. These dogs possess a strong and muscular build, coupled with a short coat that requires minimal grooming, making them suitable for families seeking a devoted and low-maintenance canine companion.


Known for their gentle and affectionate nature, this breed is highly devoted and protective towards their family. As natural guard dogs, they are brave, loyal, and strong-willed, making them excellent companions for those seeking a watchful yet loving pet. While they can be wary of strangers, proper socialization from an early age helps to ensure they are well-mannered and confident in various situations. With proper training and guidance, these dogs exhibit a calm and steady temperament, making them a beloved choice for families looking for a loyal and devoted four-legged friend.

Size and Appearance

The bullmastiff breed is known for its large and powerful build, standing tall and commanding. These dogs have a broad head with a short muzzle and droopy, V-shaped ears. Their muscular bodies are well-proportioned and robust, showcasing strength and agility. With a wide chest and strong legs, bullmastiffs exude a confident and imposing presence. Their coat is short and dense, typically coming in shades of fawn, red, or brindle. Overall, the bullmastiff's appearance combines elegance with strength, making them a striking and formidable breed.

Health and Lifespan

Bullmastiffs are generally healthy dogs but may be prone to certain health issues, including hip and elbow dysplasia, bloat, and certain types of cancer. Regular exercise, a balanced diet, and routine veterinary check-ups are essential to maintaining their well-being. With proper care, a bullmastiff can have a lifespan of around 8 to 10 years on average. It's important for owners to be aware of common health concerns and to provide a healthy lifestyle to ensure their bullmastiff lives a long and happy life.

Family Compatibility

Known for their protective and affectionate nature, these dogs are incredibly family-oriented. They bond closely with their loved ones and are highly loyal and dedicated to keeping them safe. Their gentle and loving demeanor makes them excellent companions for families with children. Although they may appear intimidating due to their size, they are gentle giants at heart and thrive on the love and attention of their family members. With proper socialization and training, they can be incredibly well-behaved and obedient, making them an ideal addition to any loving household.

Exercise Needs

Bred as guardians, these dogs are powerful and require regular exercise to maintain optimal physical and mental health. Daily walks and playtime are essential, but they should not engage in vigorous exercise until they are fully grown to prevent joint issues. A fenced yard is ideal for them to roam safely, as they may chase after perceived threats. Incorporating obedience training during exercise sessions can provide mental stimulation and strengthen the bond between the dog and owner. Monitoring their activity to prevent overexertion is crucial, as they are prone to overheating due to their brachycephalic nature.

Diet and Feeding

Bred for strength and endurance, this breed requires a balanced diet rich in high-quality protein to support muscle development. Feeding adult bullmastiffs twice a day can help prevent bloat, a condition they are prone to. Monitoring their weight and adjusting food portions accordingly is crucial to prevent obesity, which can strain their joints. Incorporating fruits and vegetables as treats can provide essential nutrients and aid in digestion. It's essential to consult with a veterinarian to determine the right diet plan based on the individual dog's age, weight, and activity level to ensure optimal health and well-being.

Living Environment

Known for their gentle and loving nature, this breed thrives in a home environment where they can be close to their family. They are adaptable and can do well in apartments as long as they receive daily exercise. However, due to their large size, a spacious home with a fenced yard is ideal for them to roam and play freely. Bullmastiffs are indoor dogs that enjoy being around their human companions, making them excellent companions for families living in houses or apartments with adequate space for their size.


Grooming a Bullmastiff is relatively low-maintenance, requiring regular brushing to keep their coat healthy and free of loose hair. Bathe them as needed, ensuring their wrinkles are cleaned thoroughly to prevent infections. Pay special attention to their ears, nails, and teeth, keeping them clean and trimmed to avoid any issues. Additionally, brushing their teeth regularly can help prevent dental problems. Being diligent with grooming tasks will not only keep your Bullmastiff looking their best but also contribute to their overall health and well-being.

Training and Intelligence

Positive reinforcement techniques work best with this breed, as they are sensitive to harsh discipline. Consistent training routines are crucial to ensure success and prevent them from becoming stubborn. Due to their powerful build, early socialization and obedience training are essential to manage their protective instincts. Bullmastiffs respond well to firm and confident leadership, and they thrive when given a sense of purpose and direction in their training. Engaging their minds and providing mental stimulation is key to keeping them happy and well-behaved.

Exercise and Activity Requirements

Bred to be powerful and active, this breed requires daily exercise to stay healthy and happy. A mix of daily walks, interactive play sessions, and mental stimulation are essential to prevent boredom and behavior problems. Owners should provide opportunities for controlled off-leash exercise in secure areas to allow the dog to run and stretch its muscles. While they may enjoy lounging indoors, regular physical activity is crucial to prevent obesity and maintain their muscular build. Engaging in activities like agility training, obedience classes, or hiking can also help keep this breed mentally sharp and physically fit.


Proper socialization is crucial for this breed to ensure they grow up to be well-adjusted and friendly dogs. Early exposure to different people, animals, environments, and situations is key to preventing potential fearfulness or aggression. Positive interactions during puppyhood can help shape a confident and sociable temperament in adulthood. Consistent training, positive reinforcement, and frequent social outings are recommended to foster good behavior and prevent any potential behavioral issues down the road. Regular socialization efforts can help create a well-rounded and harmonious companion, capable of interacting positively with various people and animals.


The average lifespan of this breed ranges between 8 to 10 years. As they are a larger and heavier dog, some health issues can impact their longevity, such as hip dysplasia, cancer, and heart conditions. Providing proper care, regular exercise, a balanced diet, and routine vet check-ups can help promote a longer and healthier life for this beloved canine companion.

Special Considerations

Being a powerful and protective breed, it's crucial to provide consistent training and socialization from an early age to establish good behavior. These dogs have a tendency to be strong-willed, so firm and patient handling is essential. Regular exercise is key to prevent boredom and potential behavioral issues.

Guardian Instincts

Known for their exceptional guardian instincts, this breed is naturally protective and loyal. Descended from powerful and fearless ancestors, bullmastiffs possess a strong sense of territory and will defend their family with courage and determination. Their imposing presence alone is often enough to deter potential threats, but if provoked, they will not hesitate to act to protect their loved ones. While they are gentle and loving with their family, their innate guardian instincts make them excellent watchdogs and reliable protectors. Training and socialization are essential to harness and channel their natural protective instincts effectively.

Allergies and Shedding

Overall, bullmastiffs are a great option for allergy sufferers looking for a low-maintenance dog with minimal shedding tendencies.

Additional costs include supplies like a crate, collar, leash, and food bowls, which can total around $200. Yearly expenses for food, grooming, medical check-ups, and vaccinations amount to approximately $800-$1,000. Emergency medical costs should also be factored in, with pet insurance costing around $300-$600 annually. Training and socialization classes can be beneficial but add to the overall cost. Over a bullmastiff's lifespan of 8-10 years, the total cost of ownership averages around $13,000-$15,000.

Adoption fees may vary depending on the organization and the age/health of the dog. Prospective owners can also consider contacting reputable breeders, although adoption is often a great option to provide a loving home to a bullmastiff in need.
