The Bullmastiff dog breed is a sturdy and fearless family watchdog. While standoffish with outsiders, they’ve got a warm heart for their close ones.

Called the “silent watchdog,” this breed is yet so docile that they make wonderful apartment dogs. Dog owners should be aware that these canines drool a lot. If you can get beyond a little slobber, you’ll find a huge, protective companion who will be pleased to join you on adventures, so long as you keep a space on the couch for them afterward.

All Bullmastiff dog characteristics and information are listed here for your perusal!


  • There isn't a lot of exercise required for bullmastiffs, and they'll be content with a few short walks each day.
  • Families with a Bullmastiff can thrive even if one or both parents work. When it comes to being alone, pups aren't too anxious, but they'll still need someone to come home and let them out for potty breaks.
  • Dogs like bullmastiffs shed very little and need only minimum maintenance.
  • Bullmastiffs can easily live in a condo or an apartment due to their laid-back disposition..
  • This breed, if not properly socialised, can be violent towards other animals.
  • Bullmastiffs should be housed indoors with their owners.
  • Keep your bullmastiff indoors during hot or humid weather because they are prone to heat exhaustion and heatstroke.
  • Bullmastiffs are known for drooling and being gassy. This breed is not for you if you have a problem wiping up drools.
  • In order for bullmastiffs to be successful, they must be trained from an early age. It is possible to reduce aggressive behaviour and stubbornness through education and socialising.
  • When it comes to snuggling up to you, Bullmastiffs are a big hit. They take up a lot of space, but in return they show you a lot of affection.
  • Bullmastiffs make excellent watchdogs and will defend their family and house to the death if necessary. Intruders are scared off by their sheer presence and self-assuredness.
  • Toddlers can be accidently knocked over or stepped on by bullmastiffs.
  • Bullmastiffs have a high pain threshold thus it can be difficult to establish if the dog is hurt.


Social Appearance 


It's a common misconception that a little dog is better suited to living in a limited space. Many tiny dogs have too much energy and are too yappy to live in an apartment building. An apartment dog's best attributes include being quiet, low energy, somewhat peaceful indoors, and respectful to the other inhabitants. Your dog's personal space in your apartment can be improved by purchasing one of these fantastic dog cages.

Sensitivity Level

Depending on the dog, a strong rebuke can be taken in stride by some, while others regard even the tiniest hint of disapproval as a personal attack. If you have a loud or pushy owner, a chaotic home, or a routine that is unpredictable or variable, your low-sensitivity dog, often known as "easy-going," "tolerant," "resilient," or even "thick-skinned," will be able to handle it better. Do you have young children, host a lot of parties, or have a hectic lifestyle? Choose a dog that isn't overly sensitive.


You can't tell from looking at them whether or not they're hyperactive, but when they do anything, they do it vigorously. They tug at their leashes (unless you teach them not to), they push their way through barriers, and they down their meals in huge, gobbling gulps. A home with young children or an elderly or feeble person may not be the best place for these dynamos to learn proper etiquette. On the other side, a dog with poor vitality adopts a more reserved demeanor.

Potential for Playfulness

The playful nature of certain dogs never fades away, and they're always ready for a game, whereas the reserved and serious tendencies of other dogs develop through time. Think about how many times a day you want to play fetch or tag with your dog, and whether or not you have children or other dogs who can act as substitutes.

Personality Appearance


In the same way as working dogs, such as those that herd sheep, are bred for intelligence and decision-making, working dogs like those who run all day need to exercise their bodies. The two most common activities that a bored pet engages in are digging and chewing, both of which require mental stimulation. There are several ways to keep a dog's brain active, including obedience training, interactive dog toys like tug of war, and dog sports like agility and search and rescue.

Energy Level

Energy-draining dogs are always on the lookout for a new activity. There are several jobs that require a lot of stamina from dogs, such as herding livestock or recovering prey for hunters. Children are more likely to engage in activities such as jumping, playing and exploring new sights and smells as a result of this change in their environment

A low-energy dog is more like a couch potato than a dog that needs a lot of exercise. Think about your level of physical activity and whether or not you find a hyperactive dog irritating before making your final choice.

Easy To Train

Easy to train dogs can more easily form associations between a cue (like "sit"), an action (like sitting), and a reward than dogs that are more difficult to train. Dogs that require more time, patience, and repetition are more difficult to train.

Getting your dog interested in training will require incentives and games because many breeds are intelligent but have a "What's in it for me?" mentality when it comes to learning new things.

Family Affection Level

Affectionate With Family

Since puppyhood, some breeds remain aloof and independent; others form deep bonds with one individual but are uninterested in the rest of the family; still other types shower their entire family with affection. Canines raised in homes with people tend to be more open to human interaction and develop stronger ties, regardless of their breed or upbringing.


Kids-friendly dogs are calm, strong enough to bear the hefty hugs and pets kids can dish out, and have an unfazed attitude about rushing, scream-inducing children. There are several names you may not expect to see on the list: Fierce-looking Both Boxers and American Staffordshire Terriers are regarded as family dogs (which are considered Pit Bulls). Chihuahuas, which are small, sensitive, and potentially sharp, are not always family-friendly.

Dog Friendly

Dog friendship and human friendship are two entirely different things. The fact that a dog is friendly with humans doesn't mean it's immune to aggression or aggression from other dogs; some canines choose to play rather than fight; others will just run away. The type of animal isn't the only consideration. Dogs who have spent a lot of time playing with their littermates and their mother at the age of six to eight weeks are more likely to be socially competent.

Physical Appearance

Amount of Shedding

Having a dog in the house means that you'll have to deal with some level of dog hair on your clothing and in the home. It's worth noting, however, that shedding varies widely among breeds. Some dogs shed all year long, while others ``blow" just during specific times of the year, and still others don't shed at all. If you're a stickler for cleanliness, you'll need to choose a breed that sheds less or lower your expectations. You can use a deshedding tool to keep your house a little cleaner.

Drooling Potential

While greeting you, some dogs may cover their arms with ropes of drool and create large, wet patches on your clothing. If you don't mind a little drool, go for it; but if you're a stickler for cleanliness, you may want to look for a dog with a low drool rating.

Easy To Groom

Some breeds of dogs can simply be brushed and left alone, while others require frequent washing, trimming, and other grooming in order to maintain their health and appearance. If you don't have the time or money to take care of a dog that requires a lot of grooming, you may want to look into hiring a professional.

Exercise Needs

Evening walks around the neighbourhood are perfectly acceptable for some breeds. Others, particularly those trained for physically demanding vocations like herding or hunting, require regular, rigorous exercise.

They can gain weight and release their pent-up energy in ways you don't like, including barking, chewing, and digging, if not given enough exercise. Those looking to train their dog for an energetic canine activity, such as agility, should consider getting a dog that needs a lot of exercise.

Despite being one of the oldest breeds in the UK, the Bullmastiff is likely a very recent addition. No evidence exists to support the theory that Bullmastiffs and Bulldog mixes existed prior to 1791, despite infrequent mentions of these breeds.

The Bullmastiff's known history began at the close of the nineteenth century, when vast estates' gamekeepers' lives were threatened by poachers. The Mastiff was too slow, and the Bulldog was too little, so they couldn't find a suitable dog for the job.

The "Gamekeeper's Night Dog," as it was affectionately known, was created by crossing many different breeds in an attempt to find the ideal dog for a gamekeeper. A dark brindle was the most popular colour, as it faded into the darkness. Dogs with black masks became increasingly popular as guard dogs as their reputation expanded, with estate owners preferring to use the dogs as estate guardians and preferring the fawn-colored dogs with black masks.

In the end, the ideal Bullmastiff ended up being 60% Mastiff and 40% Bulldog. Until 1924, the English Kennel Club had regarded the breed to be pure and recognised it. The American Kennel Club (AKC) was established in 1933.

Personality and Temperament

Compared to other breeds, bullmastiffs are kind and friendly. For families with youngsters who are moderately well-behaved, these dogs are excellent companions. However, when a stranger enters the picture, the bullmastiff's laid-back attitude toward family members is likely to alter. These dogs have a tendency to be wary of strangers.

The bullmastiff is no slouch, despite the fact that he is devoted to his family. Training him can be a problem because of his tendency to think on his own. When it comes to animals, he may not be as forgiving to them as he is of his human counterparts. If you're contemplating getting a bullmastiff for your family, proceed with extreme caution.

As a loyal friend and watchdog, the Bullmastiff is gentle and quiet. When threatened, this dog is a fearless warrior. Bullmastiffs are stubborn and will not readily be coaxed into action. The introduction of new dogs should be approached with caution in some cases. Males, in particular, have a hard time putting up with each other. They get along well with children, but it's best if they're raised alongside kids. For the Bullmastiff, a stern but caring household is necessary. This is not a dog for the weak-willed or the timid.


Bullmastiffs make wonderful family pets because of their kind temperaments and protective natures. When properly socialised and trained, they will be a joy to be around. If a little child is mistreated, they have the capacity to knock them down like large canines. Make sure to keep an eye on the dog anytime it is around young children and think twice before getting a Bullmastiff for your family if you have young children.

Tolerant of having their people gone throughout the workday as long as they receive attention before and after, they prefer to live indoors among others. However, a bullmastiff might develop destructive tendencies if left alone in the yard for an extended period of time without access to family interaction. It's important to remember that the Bullmastiff is above all else a devoted and affectionate house companion.


Bullmastiffs have a short life expectancy of 7 to 9 years, making them vulnerable to a wide range of health problems. You can still keep one as a pet if you like. It's critical that prospective puppy parents are informed of these concerns in order to provide their pup with the best possible life expectancy.

Hip and Elbow Dysplasia

Hip and elbow dysplasia are common in large-breed dogs like the Bullmastiff, which is one of the most popular breeds in the country. A misaligned joint is what we mean by this ailment. A health screening and OFA certification of the hips and elbows of the parents should always be requested when purchasing a puppy from a breeder. It's a good idea to acquire the vet's wellness check if you're going to adopt a dog. Maintaining a healthy weight, providing regular exercise, and, in older dogs, supplementing with joint supplements will help alleviate many of these orthopaedic difficulties. Surgery may be required in extreme circumstances.

Gastric Dilatation-Volvulus (GDV)

In GDV (also known as "bloat"), the stomach suddenly and dangerously twists and turns on itself. Instead of one large meal, feed your dog two or three smaller ones spread out throughout the day, and use a slow feeder bowl, which forces your dog to consume only a few pieces of food at a time. Exercise should be avoided for at least an hour after eating, whether it's before or after. Contact your veterinarian right away if you suspect your dog has GDV.


Bullmastiffs are prone to lymphoma and mast cell tumours, two of the most prevalent diseases in dogs. Chemotherapy can be used to treat lymphoma, a cancer of the white blood cells that primarily affects the immune system. It is not uncommon for MCTs to resemble less malignant growths on the skin. Make an appointment with your veterinarian as soon as you see any new lumps. Treatment for MCTs, particularly with radiation, is highly effective and safe.


Keeping your Bullmastiff in good shape is essential. Orthopedic problems are common in a large-breed dog that is obese (even if they put on just a couple of extra pounds). Talk to your veterinarian if you see that your dog is growing a "dad bod." If your dog is overweight, they can help you devise a calorie-controlled diet that still meets their nutritional needs.

Recommended Health Test

  1. Hip Evaluation
  2. Elbow Evaluation
  3. Cardiac Exam
  4. Ophthalmologist Evaluation
  5. Thyroid Evaluation


Each meal should contain between 1 1/2 cups and 2 cups of dry dog food, depending on the size and activity level of your Bullmastiff. Fresh, clean water should always be available to your dog. Your dog's dietary and activity requirements will evolve over time, so it's a good idea to consult with your veterinarian about the best course of action.

It is possible to prevent bloating and stomach torsion in your dog by feeding him two meals a day (gastric dilatation-volvulus). Gas output might increase when a dog gulps down its food or eats a huge meal. That can lead to a medical emergency, since the stomach might twist and cut off blood supply.

Keep an eye on your dog's weight, and take action if you see any extra pounds coming in. Dogs that are overweight or obese are more likely to suffer from a variety of health issues.


Routine grooming is all that is needed to maintain the Bullmastiff's short coat. The shedding of this breed is moderately low. Ears and facial skin folds (if any) should also be kept clean and dry. It's best to be prepared for a drool-fest when this dog tosses its head—a slobber rag is a good idea.

Keep an eye on the nails of your dog and trim them if you notice any clicking noises on the floor as a result of activity. It's also a good idea to brush your dog's teeth a few times a week for optimal dental hygiene.


Although the Bullmastiff is a very sedentary breed, it still need regular exercise to keep it in shape and energised. Start effective leash training as soon as your dog is a puppy by taking him for a walk at least twice a day. In adulthood, the Bullmastiff will be so powerful that you'll have a hard time controlling it if it tugs on the leash. Because these dogs are inclined to get into fights with other dogs, they should not be permitted to roam around a dog park unsupervised. Overheating is an issue for the Bullmastiff, because it has a short snout. Keep your dog cool in hot weather and avoid overdoing it with exercise.


The Bullmastiff, like any other dog, requires adequate training and socialisation. Although the breed is intelligent and has a tendency to be self-sufficient, it requires a rigorous and consistent approach to training. Dogs that jump on people when they're young can pose a danger to themselves and others when they're older.

Multi-pet households should avoid getting a Bullmastiff. Cats and other small animals may be harassed by them even if they are raised together. They also have a hard time getting along with other dogs. As a rule, male Bullmastiffs and other male canines of any breed cannot coexist peacefully. They'll go toe-to-toe with any animal that crosses their path.

Children and Other Pets

Bullmastiffs are tolerant and protective of children, yet their size makes them prone to tripping over or stepping on a little child. When contemplating whether or not to get a Bullmastiff, keep in mind the age and size of any children you may have.

Teaching children how to approach and touch dogs is essential to preventing ear biting or tail-pulling incidents between dogs and young children.

Teach your youngster to never disturb a sleeping or eating dog, or to try to take away the dog's food, by approaching them. A dog should never be left alone with a child, no of how friendly the dog may be.

It's possible that a Bullmastiff will bite a dog it has never met before. These dogs get along best with canines of the same gender that have grown up around them.

In general, Bullmastiffs get along with cats if they've been socialised with them from an early age. Cats that stand up for themselves have a better chance of surviving than cats that flee.


Make sure that your house is ready for a new addition to your family if you plan on getting a Bullmastiff puppy. Remove anything that could be dangerous to a puppy or that you don't want to get chewed up by one.

The moment you bring your dog home, you should begin training him or her immediately. It's far easier to train a young bullmastiff than an older one, so get them started early on the training process. Remember to seek out ways to socialise your dog in light of this. As a result, they will be more prepared to interact with other people and animals.

Potty training your Bullmastiff can be aided by crate training your dog first. When you aren't home, the puppy won't be able to get into your belongings and chew them up.

Puppies of bullmastiffs will require some play time and physical activity. Puppies go through a period of rapid growth, therefore exercising them too much can be harmful. For this reason, they should avoid overdoing it when it comes to exercising.

Dogs similar to Bullmastiff

Bullmastiffs have certain qualities with Boxers, Bulldogs, and Tibetan Mastiffs, three canine breeds.


Originally intended to be working dogs, both Boxers and Bullmastiffs are descendants of the Boxer breed. As far as shedding goes, they both shed moderately and are easy to groom. Even though Boxers are smaller, Bullmastiffs are much more massive. Male Boxers weigh 65 pounds on average, while male Bullmastiffs weigh 120 pounds on average.


The Bullmastiff was derived from two different breeds: the Bulldog and the Bulldog. They, too, have a very short muzzle, like the Bullmastiff, which gives them their name. If left alone for an extended period of time, either dog may develop separation anxiety. Bulldogs are smaller in stature, but Bullmastiffs are much larger. Bullmastiff males often weigh 120 pounds, while Bulldog males typically weigh 54 pounds.

Tibetan Mastiff

It's hard to believe that Tibetan Mastiffs aren't bigger than Bullmastiffs. Male Bullmastiffs weigh 120 pounds on average, whereas females weigh 155 pounds. Bullmastiffs, on the other hand, are less inclined to bark than Tibetan Mastiffs. Both dogs have the potential to be very protective of their home territory. Both of them would make wonderful pets for a household.
