Bullmastiff

The Bullmastiff is a breed that effortlessly marries strength with a gentle demeanor, making them both imposing and endearing. Originally developed by blending the Old English Mastiff and the Bulldog, these dogs were crafted to assist gamekeepers in thwarting poachers. Today, they remain vigilant protectors but have also become cherished family members due to their unwavering loyalty and protective instincts.

These dogs are substantial and robust, exhibiting a calm assurance alongside their keen intelligence and vigilance. While they are receptive to training, Bullmastiffs tend to be contemplative, often requiring a clear understanding of commands, which necessitates patient and consistent training. Their demeanor is a blend of spirited energy and tranquility, ideal for owners who provide firm guidance and an active lifestyle.

Bullmastiffs thrive in homes with ample space, such as a secure backyard, where they can exercise both physically and mentally. They are not suited for apartment living or novice dog owners due to their considerable size, strength, and specific socialization requirements. However, for those who can meet their needs, they offer unparalleled companionship and security.

Caring for a Bullmastiff involves daily moderate to vigorous exercise, regular grooming to maintain their short coat and clean facial folds, and attentiveness to health issues common in large, flat-faced breeds. They flourish in stable environments with consistent routines, allowing them to express their natural guarding instincts safely.

Ideal Owners

Perfect for experienced dog enthusiasts seeking a powerful yet devoted family protector, homes with secure backyards offering room to explore, those committed to ongoing training and socialization, and individuals desiring a natural guardian that is fiercely loyal.

Important Considerations

Experienced handling and early socialization are crucial to prevent dominance issues, substantial daily exercise is necessary with careful monitoring in warm weather due to their brachycephalic nature, predisposed to inherited health challenges like hip dysplasia and gastric torsion, and better suited to families without very young children due to their playful nature and size.

In the 19th century, the Bullmastiff was born in England as a purposeful crossbreed of the Old English Mastiff and the Old English Bulldog. This combination aimed to create a formidable and brave dog capable of aiding gamekeepers in protecting estates from poachers. Although dogs with similar traits existed earlier in Europe, the Bullmastiff was fine-tuned to meet the specific needs of British gamekeepers.

Early Development

The breed's lineage includes ancient Molosser and Alaunt dogs, which are believed to have been brought to Britain around 2,000 years ago, contributing size, strength, and endurance. Additional input from breeds like the Bloodhound, Saint Bernard, and Great Dane enhanced their versatility and resilience. Early Bullmastiffs were less standardized, often resembling the Staffordshire Bull Terrier more than today's version, yet they consistently demonstrated loyalty and protective instincts. They were highly valued by gamekeepers during the 17th and 18th centuries for their ability to quietly track and detain poachers without unnecessary aggression.

Modern Recognition

Official recognition was achieved in 1924-1925 with the formation of the British Bullmastiff League (initially the Midland Bullmastiff Club). The Kennel Club formally acknowledged the Bullmastiff breed standard in 1925, cementing its status as a distinct breed. Since then, dedicated breeders have refined the breed, ensuring a balance of power, temperament, and health. The breed's role has expanded beyond gamekeeping to include police, military, and private security work, highlighting its versatility and reliability.

Despite changes in appearance over time, the Bullmastiff’s intelligence, protective nature, and devotion remain defining traits, ensuring its ongoing popularity among dog lovers worldwide.

Size and Build

Bullmastiff males typically measure 25 to 27 inches at the shoulder, weighing between 110 and 130 pounds, while females stand 24 to 26 inches tall and weigh 90 to 120 pounds. These dogs boast a robust, muscular build with a broad chest, level back, and substantial bone structure. Their physique radiates strength without excessive bulk, embodying an athletic yet balanced form ideal for physical work and agility.

Coat and Colors

The Bullmastiff's coat is short, dense, hard, and close-lying, providing excellent weather resistance. Recognized colors include brindle (with or without a black muzzle), fawn (with or without a black muzzle), and red (with or without a black muzzle). Slight white markings on the chest are permissible. The distinctive black mask blends into the coat around the eyes, adding expressiveness to the face.

Distinctive Features

The head is large and square with a pronounced stop, broad nostrils, and a moderately short muzzle. Wrinkles appear on the forehead and face when the dog is alert or interested. Eyes are hazel or dark brown, set wide apart with a distinct furrow between them. Ears are small, V-shaped, folded close to the head, and set high and wide apart with a slightly darker hue than the coat. The jaw may be slightly undershot, but a more level bite is preferred; strong, well-spaced teeth support the powerful jaw structure.

The neck is arched, muscular, and of moderate length. The legs are strong, straight, and well-muscled, with broad shoulders and a deep chest. Hindquarters are robust with deep flanks and powerful thighs. Feet are compact, oval-shaped, with arched toes and hard pads. The tail is set high, thick at the base, tapering to a point, and carried straight or with a slight curve.

Gender Differences

Males tend to be slightly larger and more robust than females, often displaying more prominent musculature. Females may be slightly more affectionate and less dominant, though individual variation exists. Both genders share the breed’s hallmark loyalty and protective instincts.

Gait/Movement

Bullmastiffs exhibit a purposeful, powerful gait characterized by rhythmic, ground-covering strides. Their legs move in diagonal pairs (front right with left rear and vice versa), never crossing over. The back remains firm with significant thrust generated from muscular hindquarters, demonstrating balance and agility despite the breed’s size.

Breed Standard and Faults

The Kennel Club emphasizes health and function over exaggerated features. Disqualifications include oversize or undersize dogs, poor bite, or physical anomalies that hinder health or movement. Both male testicles must be descended for show eligibility. Variations slightly outside the standard range may be tolerated if health and soundness are uncompromised.

Core Personality Traits

The Bullmastiff is celebrated for its bravery, loyalty, and protective nature, forming profound bonds with its family. Early, consistent socialization is essential to ensure well-rounded behavior and to establish clear leadership within the household. Without experienced handling, dominant tendencies can emerge due to their strong-willed nature and size, making them unsuitable for first-time dog owners.

Social Behavior

They are generally reserved with strangers, often vigilant and watchful, which makes them exceptional guard dogs. However, they typically respect introductions facilitated by their owners, displaying calm acceptance rather than aggression. This silent vigilance means they seldom bark unnecessarily, alerting owners only when required.

Working Instincts

Bullmastiff puppies are lively and playful but can be overwhelming for very young children due to their size and exuberance. They thrive on interactive play such as fetching games, but care must be taken not to overexert them, especially considering the breed’s brachycephalic traits which can affect breathing.

Common Behavioral Challenges

The breed adapts best to homes with secure backyards allowing freedom to move safely. They are prone to separation anxiety if left alone too long and benefit from environments where companionship is frequent. While Bullmastiffs generally do well with other pets when socialized early, their strong prey drive necessitates careful introductions and management around smaller animals.

Training a Bullmastiff requires patience, consistency, and an understanding of the breed’s intelligent but sometimes stubborn temperament. Early training is crucial, starting with fundamental commands like sit, stay, come, quiet, leave it, down, and bed to establish boundaries and communicate expectations clearly.

Puppy Training Priorities

From the first weeks, focus on socialization with diverse environments, people, and other animals to develop well-balanced confidence. Teaching impulse control and respect for the owner’s role as alpha is essential, as Bullmastiffs may test limits if uncertain about their position in the household.

Training Methods That Work

Positive reinforcement using treats, praise, and play serves best, as harsh corrections can provoke resistance or fear. Short, engaging sessions (10-15 minutes, multiple times daily) maintain focus without overwhelming the puppy. Consistent use of simple one-word commands aids understanding and obedience.

Advanced Training Potential

Bullmastiffs excel in activities utilizing their guarding instincts and strength such as obedience competitions, protection work, and scent tracking. However, due to their brachycephalic anatomy, heavy physical endurance activities should be managed carefully to avoid respiratory strain.

Common Training Mistakes

Avoid inconsistent command usage or leniency in rule enforcement which can lead to behavioral issues. Underestimating the breed’s strength and assertiveness can lead to control difficulties, so early establishment of leadership is non-negotiable.

Bullmastiffs, due to their large size and tendency towards boisterous play when young, are best suited to families without toddlers or very young children. Their sheer size means even well-intentioned interactions can inadvertently upset small children. Adult supervision is critical during any interaction between Bullmastiffs and children.

Age-Specific Interactions

Young toddlers and babies should not be left unattended with a Bullmastiff as the dog's playful nature combined with their strength presents safety drawbacks. Older children and teenagers often benefit from the dog’s protective instincts and can learn respectful interaction under guidance.

Teaching Children Proper Interaction

Parents should educate children on how to approach and handle large dogs safely: avoiding sudden movements, respecting the dog’s space, and recognizing signs of stress or discomfort in the dog. Teaching when and how to play gently, and not disturbing the dog during feeding or rest times, helps maintain harmony.

Breed-Specific Considerations

Bullmastiffs are less tolerant of small children’s unpredictability and noise, especially in puppyhood. Their brachycephalic anatomy also means they can become easily over-excited, so play sessions should be moderated. Early training that emphasizes calm tolerance benefits family life.

Creating Safe Environments

Supervision is essential; children and dogs should never be left alone together. Providing a defined safe space for the dog to retreat to helps prevent stress. Introducing any new family members gradually ensures smooth adjustment for all.

The Bullmastiff's health requires vigilant care, especially given its predisposition to specific hereditary and breed-related conditions. Their average lifespan is between 7 and 9 years, reflecting the challenges faced by large, brachycephalic dogs.

Breed-Specific Health Conditions

The breed is notably susceptible to bloat (gastric dilatation-volvulus), a potentially fatal twisting of the stomach common in large deep-chested breeds. Preventative measures include feeding multiple small meals a day and avoiding vigorous exercise around feeding times. Hip and elbow dysplasia are frequent concerns, often leading to arthritis and mobility impairments. Other conditions include hypothyroidism, various cancers including mast cell tumors, entropion affecting the eyelids, subaortic stenosis, kidney and bladder stones (cystinuria), and various skin allergies exacerbated by facial folds.

Genetic Testing Requirements

Responsible breeding requires screening for known issues such as hip and elbow dysplasia via the BVA/KC Hip Dysplasia Scheme, and testing for persistent pupillary membrane (PPM), progressive retinal atrophy (PRA variants including PRA-rho and PRA-D), and canine multi-focal retinopathy (CMR) through DNA-based diagnostics. Regular annual eye testing for PRA is advised, particularly for stud dogs.

Preventive Healthcare Schedule

Puppies receive initial vaccinations typically at 10-12 weeks with booster protocols continuing as advised by veterinarians. Neutering and spaying are generally recommended between 6 to 9 months, considering individual maturity and health. Routine parasite prevention, dental care, and weight monitoring aid in maintaining health.

Insurance Considerations

Due to the breed’s health profile, insurance premiums tend to be higher than average, with quotes ranging from approximately 60 to over 15 monthly depending on coverage. Owners should select comprehensive policies covering hereditary conditions and accidents to manage potential costs effectively.

Caring for a Bullmastiff involves dedicated daily attention to grooming, exercise, nutrition, and health monitoring. Their short coat requires weekly brushing to remove dead hair and maintain skin health, while facial folds need regular cleaning to prevent infection. Owners should monitor for signs of skin irritation or allergies frequently.

Daily Care Routine

A typical day includes morning and evening walks totaling 60 to 120 minutes, combined with mental stimulation through interactive play or training. Proper hydration and a calm resting environment support their well-being. Monitoring breathing during warm weather or exertion is essential given their brachycephalic structure.

Living Environment Needs

Bullmastiffs thrive in homes with secure, spacious gardens where they can move freely and express natural behaviors safely. Apartments are generally unsuitable unless there is frequent access to outdoor space. A well-fenced garden is imperative to prevent escape or accidents.

Seasonal Care Adjustments

In summer, care must be taken to avoid overheating; limited exercise during the hottest parts of the day and availability of shade and cooling aids are necessary. Winter months may require extra bedding or warmth to counteract the chill, especially for older dogs.

Senior Care Adaptations

As Bullmastiffs age, adjustments include softer bedding to ease joints, controlled weight management to reduce arthritis progression, and limited but regular gentle exercise to maintain muscle tone. Regular vet visits increase in importance to monitor emerging age-related issues.

Bullmastiffs are relatively low maintenance when it comes to grooming, thanks to their short, dense coats. A weekly grooming routine with a mitt or soft brush removes loose hair and stimulates skin health. Special attention must be given to cleaning and drying the facial folds properly to prevent bacterial infections and dermatitis, common challenges in the breed due to their skin folds.

Coat Maintenance Schedule

Weekly brushing sessions require about 10 to 15 minutes per dog. Bathing should be conducted as necessary, typically every few months unless skin issues arise. Daily or frequent wiping of facial folds with a damp cloth is essential to keep these areas dry and clean.

Professional Grooming Requirements

Bullmastiffs generally do not require professional grooming or clipping besides occasional bath treatments. Skin folds might require professional cleaning if infections develop.

Home Grooming Techniques

Use grooming mitts or soft brushes for coat maintenance. Facial folds should be gently wiped and dried using dog-safe wipes or saline solutions recommended by veterinarians. Nail clipping and ear cleaning are routine tasks to perform regularly to prevent common infections or injuries.

Common Grooming Challenges

Owners should be vigilant for hotspots, yeast infections, or irritations in skin folds. Seasonal shedding is moderate, mostly coinciding with spring and autumn, and can be controlled through regular grooming.

Bullmastiffs require at least 60 to 120 minutes of exercise daily to maintain their physical and mental health. This includes two walks daily with moderate duration and pace, supplemented by play sessions for mental stimulation.

Suitable Activities

Ideal activities include leash walks, scent work, obedience training, and gentle play such as fetch. High-impact or prolonged strenuous exercise should be avoided, especially for puppies or brachycephalic individuals prone to respiratory issues.

Exercise Restrictions

Puppies under 12 months need careful exercise management to protect developing joints. Extreme heat should limit outdoor activities due to the risk of overheating. Owners should monitor breathing and fatigue signs closely.

Mental Stimulation Ideas

Enrichment games such as puzzle feeders, obedience drills, and scent scenting exercises engage their intelligence and reduce boredom. Regular interaction and challenging play help satisfy their guarding instincts and mental needs.

Example weekly schedule might include morning and evening walks, with short training sessions and play interactions in between, adjusting for weather and the dog’s energy levels.

Feeding a Bullmastiff requires careful attention to diet, portion control, and timing to support healthy growth and minimize risk of bloat. Puppies should be introduced gradually to new diets to avoid digestive upsets, maintaining consistent, high-quality puppy food.

Nutritional Requirements

The breed benefits from diets optimized for large breeds, supporting joint health and muscle maintenance with appropriate protein (18-22%) and fat (8-12%) levels. Caloric needs vary with age, size, and activity levels.

Feeding Schedule Guidelines

Puppies require feeding 3-4 times daily with measured portions tailored to growth stages. Adults do well on twice daily feeding, morning and evening, to prevent stomach issues. Avoid feeding immediately before or after exercise to reduce bloat risk.

Special Dietary Considerations

Due to the breed's predisposition to allergies and obesity, diets should avoid excessive fillers and cereals. Supplements supporting joint and skin health are often beneficial. Water must be available at all times.

Weight Management

Maintaining ideal body condition is critical; owners should monitor the dog’s waist and ribs. Overweight dogs face higher risks of health problems including joint stress and reduced lifespan. Adjust food intake and exercise accordingly.

Feeding guides suggest daily portions gradually decreasing from approximately 600g for growing puppies at 2 months to adult maintenance amounts of 400-600g depending on activity and size. Owners should consult vets on specific feeding plans.

The cost of acquiring a Bullmastiff puppy in the United States typically ranges from $1,000 to $2,200, influenced by factors like breeder reputation, location, pedigree, and lineage. Regional variations include:

• Northeast: $1,500 to $2,500
• South: $1,200 to $2,200
• Midwest: $1,300 to $2,000

Finding Ethical Breeders

Look for breeders who are registered with The Kennel Club and preferably members of the British Bullmastiff League or other recognized breed clubs. Visit breeder premises personally to assess living conditions, meet the dam and sire, and observe puppies’ health and socialization. Avoid breeders who pressure for deposits without meeting dogs or who offer unusually low prices, as these are often scams or irresponsible sellers.

Health Testing Verification

Verify the breeder’s health screening certificates for hips, elbows, eyes, and any genetic tests recommended for the breed. Confirm that puppies have received their first vaccinations, microchipping, and early socialization. Responsible breeders provide transparent documentation and support.

Puppy Selection Process

Choose a puppy with a stable temperament, good social skills, and clear signs of health such as clean eyes, ears, and coat. Avoid overly shy or aggressive individuals. Discuss the puppy’s lineage and any specific needs or traits with the breeder.

Contract and Guarantee Review

Review contracts carefully to understand return policies, health guarantees, and spaying/neutering requirements. A reputable breeder offers written agreements protecting both the puppy and the buyer.

Rescue and Adoption Options

Considering adoption from breed-specific rescues like the British Bullmastiff Council or others can be a responsible choice. Rescues often have dogs of varying ages needing permanent homes that understand the breed.
