Diane Collings is a two-time Past President of Mastiff Club of America. She’s also the current Judges Education Mentor/Presenter. Diane says she’s often asked if she’s walking Bullmastiffs when out with her Mastiffs. They might assume that it must be larger because it is called a bull. It seems that the Bullmastiff dog is more well-known to the public.

Sherry Boldt is a Bull mastiff breeder and owner-handler who has been around for more than twenty years. Boldt, a former member of The American Bullmastiff Association’s board and current Microchip Chair, believes that “many people use the generic name mastiff” for both breeds.


What is a mastiff?




Mastiffs are a large canine family that dates back over 3000 years. Many Mastiff breeds are similar to the Pittbull dog family. Mastiffs are considered to have evolved from the Molosser family of dogs. This group most commonly produced breeds that were used for cattle herding. These dogs are not herding breeds, but they have a different history!

What Is a Bullmastiff?

The breed of dog originated in England in the late 1800s. It came into existence because of crossing breeds like English mastiffs with an English bulldog. Bullmastiff is more affectionate and gentle. However, this breed is extremely brave and protective of its family members. Dogs require regular exercise to stay healthy due to their active and boisterous temperament.

Additionally, exercise can help to reduce the risk of becoming overweight. They are a bit hard to handle. The breed is determined, and its protective characteristics can make them difficult to train. The Bullmastiff also is extremely susceptible to hip, bloat as well as Elbow Dysplasia. The good thing is that their ailments can be treated.

What Is an English Mastiff?

The dog breed originated in England and was first discovered in the 1900s. It is an all-breed dog and massive in size. English mastiffs are affectionate and gentle. It is, however, considered as much more aggressive than Bullmastiff. The breed is ideal for guarding its owners. The breed of dog is generally extremely stubborn, so it can be quite challenging to teach. However, this breed is susceptible to health issues like hip, bloat, and Elbow Dysplasia.


Hunting mastiffs.

Instead, the Mastiff was used for hunting, war, and blood sports. It’s not something I like. Mastiffs were pitted against bears, bulls, and lions. This is especially sad because Mastiffs can be friendly and affectionate. They had to be “made” to be mean dogs. It breaks my heart so much that I cannot even speak about it.

Most famous Mastiff dog breed.

Italian Mastiff (Cane Corso)

more commonly referred to in the form of the Cane Corso. These faithful and magnificent dogs are close to that of the Neapolitan Mastiff. They’re known to be strong as well as dominant and clever. It’s not surprising as they were utilized both as guard dogs because of their size and stature and for war dogs.


The Bullmastiff breed is an amalgamation of the mastiff breed and the Bulldog. The Bullmastiff is a calm and gentle dog devoted to its family. Although they are laid-back and tolerant of anger, it turns into unstoppable guardian when this dog is threatened. Male Bullmastiffs are often very tolerant of male dogs. Generally, they can be aggressive with dogs they are not familiar with.

French Mastiff

The French Mastiff is known by some as Dogue de Bordeaux and is smaller in breed comparison to its English counterpart. Also The French Mastiff is patient, calm, and affectionate towards its families. The French Mastiff is fearless and is a perfect dog to guard with proper training and socialization.

Argentinian Mastiff

called the Argentine Dogo, this intelligent breed is fun and easy to teach and can also become a faithful guardian for their home and the people they live with. They were created to aid humans in big game hunting, like wild boar. They can be extremely strong dogs, and, in the absence of proper training or socialization, they can be aggressive towards dogs as well as other animals they’re not familiar with.

German Mastiff

The German Mastiff is commonly called a Great Dane. This breed of Mastiff is affectionate and reliable and is usually great with children. This Great Dane also usually takes very well to other pets in the household; however, it may not realize its massive size, so it is important to be watched.

Spanish Mastiff

This breed was originally bred in Spain and was used to protect sheep from predators like wolves and wolves in medieval times.

Tibetan Mastiff

Mastiffs of this breed are massive mountain dogs with exceptionally thick coats specifically designed to help keep warm in the winter months in the Tibetan Plateau and the Himalayas, which is the region where this breed originated. Very independent, extremely secure, and extremely clever, this breed will not be every pet’s ideal pet.




There are also differences in personalities. Bold, who supports two Bullmastiff rescue organizations, says that Bullmastiffs can be territorial, possessive, and loyal dogs. They are also able to discern who belongs on their property. While they seem to be driven to stop intruders, they are willing (or should be) to accept their masters.”

Bullmastiffs are not very active, but they can still work hard for you. They are low-energy and big. Many Bullmastiffs enjoy the poacher-catching heritage that has allowed them to participate in dog sports like Agility, Rally, and Tracking. They are happy to protect your couch or bed. These dogs are quick to pick up new behavior. Boldt explained, “Generally Bullmastiffs are not tolerant of repetition in training.” They don’t need to be repeated if they do it correctly the first time.

The history.

Bullmastiffs were bred in the mid-to-late-19th century to chase and pin down poachers on land owned by English aristocrats. The Gamekeepers desired dogs that could be more aggressive than the English Mastiff and larger than the Bulldog. They settled on a Bullmastiff-Mastiff mix that was 60% Mastiff/40% Bulldog. The Bullmastiff lived in the home of the Gamekeepers night dog and helped to stop poachers. Bullmastiffs were often shown in competitions to see which Gamekeeper had the best specimen. The Bullmastiff became a guard dog after poaching decreased.



The size of Bullmastiff vs. English Mastiff.

These dogs are HUGE! If you don’t have enough space in your inn for them, I fear they won’t be able to fit in. Also, it would be better if you thought about how much space you have on your sofa to accommodate them. If not, either get a bigger one or prepare to be squished. According to what I have heard, most Mastiff parents would not want it any other way.

The English Mastiff wins the award because it is heavier. Zorba, an English Mastiff, was the record holder for the heaviest dog. He weighed in at a staggering 343 pounds. He still holds the Guinness World Record for this feat, which he set in 1989. If your child asks for a pony for Christmas, you can probably buy an English Mastiff. Despite being the bigger of the two dogs, the English Mastiff is quite suited to apartment life. They are gentle and docile animals who are happy to take their daily walks.

Coat and grooming.

Mastiffs are a double-coated breed. They have a short-haired upper coat and a dense shorter coat beneath it. Mastiff coats can be fawn, apricot, and even brindle. They don’t need lots of grooming. Brushing once a week would work the best. They are seasonal shedders, and they shed more in spring and fall. A daily brush is recommended during shedding seasons. However, English mastiffs can have long fluffy hairs.

The Bullmastiff dog breed has a short but dense coat. They are moderate shedders and easy to groom. Their coat color can be red, fawn or brindle. Some of the Bullmastiffs have white marks on their chest.


Differences in intelligence and trainability Bullmastiff vs. English Mastiff?

Now, let’s find out how smart and trainable these massive and majestic Mastiff breeds can be. They both have decent levels of intelligence, yet, their intelligence is combined with a tendency to think independently and act. Also, they tend to think on their own and, as such, it can be challenging to teach. Traditional methods that rely on harsh corrections won’t work for this dog breed. This is normal for most Mastiff breeds and makes training them extremely difficult for owners who are not experienced.

Thus, both breeds need to be taught manners and obedience from the age of puppies. Their size and weight make this a crucial issue since you don’t want to scare people in the streets by controlling a wild Mastiff to attack them.

Both breeds benefit greatly from the solid leadership of a seasoned owner. If they can be led by a knowledgeable owner and a good socialization program, they can achieve a very high level of obedience. However, the English Mastiff is slightly more patient and willing to satisfy their owner through following their commands. For the Bullmastiff, a greater level of stubbornness- or independence – could be seen in simpler terms. This is probably because of its influence on the Old English Bulldog.
