The Bullmastiff was bred during the mid-1800s in England for a specific role – gamekeepers’ companion dog.
The gamekeepers of England wanted to create a dog breed that could help them in tracking down the poachers. They experimented with different breeds and tried to obtain the right kind of a dog for them. Eventually, they realized that what they needed was a dog quicker and more aggressive than a Mastiff, but less ferocious than a Bulldog. Bulldogs of 19th and the beginning of 20th century weren’t the same docile bulldogs we know today.
However, why did they need a dog of these traits?
Namely, in the mid-19th century, poaching was a hanging offense and English gamekeepers had a dangerous job of catching armed poachers. Eventually, they realized how to make their job much easier! They bred a large, quiet, but fearless dog that was fast enough to track down the poachers, and strong enough to hold them on the ground. Also, the breed’s common brindle coat provided natural camouflages needed for the job.
Since the Bullmastiff met all the requirements the gamekeepers wanted, it got nicknamed as the Gamekeeper’s Night-Dog.
But, when poaching declined, the need for Bullmastiffs to track poachers declined too, and they gained a new role: the one of a guardian dog. In fact, they were used in South Africa to guard De Beers diamond mines.
However, modern bullmastiffs are rather friendly, easygoing companions than fearless guardian dogs.
Let’s outline a few interesting things about Bullmastiff’s parent breeds: The Bulldog and The Mastiff.
The Bulldog is a dog of a bloody past: to drive cattle to market and to compete in bullbaiting. They were bred to be aggressive which is why the Gamekeepers chose exactly this breed. However today’s bulldogs are gentle pets that adore spending time with kids. They will enjoy a short walk, but will also indulge in napping on the sofa. Bullmastiffs English parent has passed him a short-muzzled head and short coat.
The Mastiff, on the other hand, is one of the most ancient dog breeds out there. He is an ancestor of the molossus, the ancient dog that existed 5,000 years ago. Mastiffs also used to have a ferocious history, as they were used as war dogs. Today’s mastiffs are still fierce, but have a much more docile personality. Being the largest dog breed of all, Mastiffs will be great guard dogs, which is a trait they passed onto Bullmastiffs too.
The Bullmastiff has a broad, wrinkled head and a short, black muzzle. His ears are V-shaped and his eyes are often dark hazel. A Bullmastiff’s tail is set high on the rear.
Bullmastiffs are large dogs of a powerful body and heavy bones. However, they are not as big as their breed parent Mastiff that is considered as the largest dog of all breeds.
Bullmastiffs will easily reach the height of 27 inches and can weigh between 100 to 130 pounds. So, if you plan on getting one, make sure you have plenty of space for this dog.
These dogs are short-coated and usually come in fawn, red or brindle colors.
Don’t let their poacher-tracking past fool you. The Bullmastiffs are incredibly intelligent and can make wonderful family dogs. They are loyal, calm, and quite easygoing when properly trained and socialized.
Bullmastiffs will be most gentle and affectionate dogs towards all family members if the socialization and training is done quite early in their lives. They can also do well with well-behaved children. However, their laid-back attitude with people from the family can easily change when someone unknown to them approaches the house.
They will likely be suspicious towards strangers and people outside the family. At times, his protective genes can also make him aggressive towards people he doesn’t know. If there are other dogs at home, a Bullmastiff will likely be less tolerant towards them than of his human family members.
Bullmastiffs have a short coat that doesn’t require a lot of grooming. Also, an average, healthy bullmastiff is a low-shedder that will however shed much more during seasonal shedding.
As long as you provide him with occasional grooming and bathing, your bullmastiff should be more than fine with it.
Regular walking should also work to trim down his nails. But, if the activities your bullmastiff has don’t wear down its nails, make sure to trim them every now and then (if you hear the nails clicking on the floor- it’s usually a sign that it’s the right time to trim the nails!).
While coat grooming and nail trimming won’t take too much of your time, there’s something else you should be taking care of when it comes to owning a Bullmastiff. Its facial skin folds should be kept clean and dry, so make sure you clear any traces of dirt, food or water on your Bullmastiff.
Since Bullmastiffs drool a lot, you might also have a bib or a cloth by your hand that you would use to clean your dog up.
Bullmastiffs are known to be dogs of quite an independent personality. While this might have some pros when it comes to their temperament, it can also bring some cons, especially when it comes to training. Usually, independence in temperament equals stubbornness in training. And this is also true for bullmastiffs. They are strong willed creatures that need a strong individual to guide them.
Make sure you have a firm, fair and consistent approach in training since the early days, and your Bullmastiff should accept to obey your commands. You have to make him realize who’s the master of the household from an early age, or your Bullmastiff will be running things his own way.
Once he accepts that you’re the boss, you will be able to maintain and enrich your special bond with your Bullmastiff.
Due to his guardian instincts, early socialization is crucial for these dogs. Make sure you expose your Bullmastiff puppy to different people, sights, sounds, and places, so that he doesn’t have unwanted, unpredictable reactions in future.
Bullmastiffs are low-energy dogs that adapt well to apartment living. However, some dogs of this breed can be moderately active while others would prefer a sedentary lifestyle. In any case, daily exercise will be enjoyed by every single dog, and so it will be for a Bullmastiff too. In order to keep him fit and healthy, make sure he has a good exercise routine.
Anyway, a bullmastiff won’t require too much exercises, in fact, excessive workouts, especially during hot days, should be avoided. Their short muzzle makes them more prone to heat exhaustion and heatstroke. If your bullmastiff stays outdoors, make sure to provide him with shade and fresh water.
Also, walking him without a leash probably wouldn’t be the best idea, as they don’t do well with other dogs.
