Let's talk Bullmastiffs

Noble and steadfast, the Bullmastiff is an imposing dog who makes an impression on everyone they meet. Their powerful appearance is deceiving, as, although definitely strong, the breed is famed for their gentle manner. Okay, and the drool, too. But the Bullmastiff’s roots as a watchdog also make them a hugely devoted companion, so much so that the Bullmastiff does not treasure their alone time. As the name suggests, the breed came about as a cross between the Old English Bulldog and the Mastiff.

Get to know the Bullmastiff

All you need to know about the breed

The Bullmastiff is an unmistakable breed of dog: Large, confident, and content, call it good breeding or an act of nature but this is a dog that takes it all in stride. The Bullmastif is a beloved family pet who has a strapping presence. At an average of 120 pounds (55kg) and equipped with a massive and muscular body, the breed is equal parts guarder and adorer. Originating in mid-19th-century England, the dog was developed on the great estates in the countryside, their strong and courageous abilities well-suited to guarding game land against poachers. They are, as one might assume, a cross between the Bulldog and the Mastiff.

The Bullmastiff breed quickly earned a reputation for being large and in charge but also as an affectionate and docile dog, one that remains cherished by families today. Those with small children however should take care as a bulky breed like this could mistakenly send them for a tumble. As a resident canine, the breed must be well-socialised from the start. They are known to be dependable and warmhearted but a dog as large as the Bullmastiff needs firm discipline in order to develop correctly.

Graced with a compact physicality, the Bullmastiff is healthy but needs to be kept so. As part of the brachycephalic family, they possess a shortened nose and snout, thus are prone to respiratory problems. Their heavy skeletal system is the … ahem ... biggest factor to keep in mind, as the support system for their substantial musculature. Obesity should be avoided as it increases the workload on joints. Make sure to feed them sound nutrition for a long and vibrant life. They’ll return the gesture with equal parts protection and devotion.

2 facts about Bullmastiffs

1. A pinner not a biter

A dog like the Bullmastiff could easily tackle any intruder, with their enormous strength and unyielding courage. They were bred to guard game land on English countryside estates against poachers, but instead of chomping the intruder, they were trained to pin them to the ground … a novel idea and perhaps a less damaging one in the long run.

2. Not the longest lifespan 

Although it’s a difficult topic of conversation, the Bullmastiff’s lifespan — an estimated 7 to 9 years — is something that needs to be thought through for new owners. As a large breed, this is the state of play when it comes to their genetic makeup. Keep your Bullmastiff as healthy as possible – your vet can help! – for a robust life all around.

History of the breed

The mastiff-type dog has existed for millenia, marked by large limbs and a sturdy body flowing with muscles. The Bullmastiff was developed most vigorously in England around the year 1860 and, as the name suggests, was a cross between the Bulldog and the Mastiff (40% to 60%), the latter of which outsizes their progeny. Initially called the Gamekeeper’s Night Dog, they were utilised on grand country estates to guard game land against poachers—pinning them against the ground instead of doing away with them.

The Bullmastiff breed has been on a steady upward trajectory ever since, quickly earning a reputation for being affectionate and docile. They were officially recognised by The Kennel Club of England, in 1924, with the American Kennel Club following in 1933.

Caring for your Bullmastiff

Grooming, training and exercise tips

The Bullmastiff grooming routine is a simple one as their short, stiff fur requires only weekly brushing to remove dead hair and shedding in the spring and fall will be customary. Unusual hair loss has been a problem for this breed at times but can be kept in check with a healthy diet. Nails should be kept trimmed. And drool? Yes, it will happen so keep a cloth on hand for a quick clean up. Exercise is a must for this breed but take notice of the amount your dog needs as some Bullmastiffs are more sedentary than others. They will enjoy running in a large, enclosed yard and taking daily walks. Training your Bullmastiff must start early: This is a large animal and one that needs proper discipline to excel. With it, the Bullmastiff’s very affable manner will surely shine through.
