Rare Mastiff Dog Breeds

The rare mastiff dog breeds are large and powerful dogs often referred to as giant dog breeds. They are also considered to be among the more exotic and unique breeds. All of these tags certainly fit and contribute to the fact that the cost to obtain one is usually quite high.

Origins Of The Mastiffs

While mastiffs have been bred for centuries for various purposes, their origins are somewhat unclear. According to some experts the dogs may have originated in Asia or the Middle East. The American Kennel Club says that images of the Mastiff may be seen on Egyptian monuments. dating back to 3000 BC 

Wherever the dogs came from, they were in Persia and Turkey by 485 BC when Xerxes brought them from there into Greece. These large dogs were more than likely used to guard flocks and herds.

Ultimately, "they" became the ancestors of later war dogs and sheepdogs. Dogs from the Molossia region gave their name to Molossers, a term still used to describe many mastiff-type dogs.

Mastiff Dog Breeds Diversity

Early on, differences were developing among the mastiffs. Some were being used as shepherds (white with longer muzzles) and the darker, heavier dogs being used in battle.

From these diverse dogs came the Great Pyrenees, the Dogue de Bordeaux, the Neapolitan Mastiff and many other dogs we still know today, as well as the Mastiff found in England.

Along with being guard dogs the Mastiff became a powerful hunting dog used to hunt bear and wolf. Some mastiff-type dogs were also used for bull-baiting and dog fighting.

The Roman Influence

There are countless descendants of the ancient mastiffs today, spread throughout many dog breeds.

As the Romans traveled into various regions, they often brought along their mastiffs which stimulated significant interest in these powerful dogs. This led to the breeding of distinct mastiff variations in many of these areas.

For instance, in Gaul, locals changed the Roman mastiffs into the Alpine Mastiff and later the St. Bernard.

The Rare Mastiff Dog Breeds

Today there are many mastiff breeds that are thriving, such as the St. Bernard, the Great Pyrenees and the Mastiff. But there are also a number of mastiff breeds which are either nearly extinct or which have been revived and are attempting a comeback.

Some of these breeds are known only in Europe. In some cases the breeds were wiped out by World War I and II. In other cases, the numbers have simply dwindled due to a lack of breeders.

So let's explore some of the rare mastiff breeds we know about.

American Mastiff

The American Mastiff dog breed (AM) originated in the United States and was,developed over several years through a cross of the English Mastiff and the Anatolian Mastiff resulting in a dog that can weigh up to 200 pounds or more.

The AM breed is registered with the Continental Kennel Club and has been recognized as a purebred breed by them since 2000.

Their overall appearance is that of a massive, impressive-looking powerful dog bearing a very similar resemblance to the English Mastiff.

While many may be overawed by an American Mastiff, this large dog is known to be a very loyal and extremely family-oriented breed - getting along well with children being patient and gentle. Once socialized they will be friendly with family friends and guests.

Though not aggressive, as a family protector, the AM's commanding appearance, standing at 3 feet tall, would make any potential intruder think twice before proceeding.

Families interested in welcoming an American Mastiff puppy or rescue should ideally have plenty of space for exercise and play and be experienced dog owners - particularly with similar sized dog breeds. A list of breeders can be found here.

Because of the large size this dog will become, it's important that puppies be trained and well-socialized from an early age to accustom them to a wide variety of situations including people and other dogs.

Regarding health, the not uncommon issues, which an informed vet will know how to treat, include:

• not surprisingly- hip dysplasia
• and bloat

The average lifespan with good care is between 8 to 12 years.

Anatolian Shepherd Dog

The Anatolian Shepherd dog is descended from ancient mastiff breeds. He is primarily a livestock guarding dog with a strong independent nature.

Also known as Anatolian Karabash and Turkish Shepherd Guard Dog, the breed originated in Turkey as far back as the Persian Empire. 

Historically this breed has a long been recognized as a top mastiff-type flock guardian being renowned for their strong protective instincts and ability to fend off predators.

Anatolians have an affectionate nature and as family companions, one could not wish for a more loyal and protective dog. They get along well with children and other pets.

However, due to responsibilities of working for decades to protect their flocks, it is not surprising that they have acquired an independent streak along with the confidence needed to make decisions.

For this reason, they must be well-socialized and trained from an early age with a self-assured strong leader they can respect and bond with.

Socialization and consistent training are essential to most breeds to become solid citizens, but is especially crucial to large dominant dogs such as the Anatolian.

In terms of appearance, the Anatolian Shepherd dog is a very large, well-muscled and powerful-looking dog breed that can weight up to 150 pounds with a height of up to 30 inches. Along with a dense double coat, these sturdy dogs are ideally suited to perform their outside job duties.

Health: To maintain the overall good health of this breed:

• Provide high quality food and water at all times,
• Take him for daily walks,
• Routinely check ears and brush teeth.
• Arrange annual check-ups including dental inspection with a veterinarian.

While not commonly disposed to hip dysplasia and bloat, owners should be informed of these conditions just in case - especially to the latter which can be life threatening. Additionally, this breed may acquire an eyelid condition known as entropian. It is good for your vet to be familiar with these health notes as well as the breed's sensitivity to anesthesia - in case any procedures require this - such as teeth scaling.

For more extensive information about this very interesting breed I have created a separate page for the Anatolian Shepherd dog here.

Bullmastiff

The Bullmastiff, one of the rare mastiff dog breeds, was developed in England during the 19th century and is believed to be a cross between two native breeds - the English Mastiff and the Bulldog.

The Bullmastiff breed was recognized by the AKC in 1934.

Background of the Bullmastiff

William Burton of Thorneywood Kennels bred an early version of the Bullmastiff. One of his dogs, known as Thorneywood Terror, became famous at gamekeepers’ shows for his ability to catch any person willing to bet that he could escape from the dog. Even with the better being give a head star, the dog always caught and toppled the unfortunate gambler!

This mastiff breed is highly protective but not aggressive, fearless, intelligent, very strong and impressively agile for its large size.

Ultimately, these attributes were put to use on large English estates where the Bullmastiff accompanied gamekeepers on night patrols to catch poachers and prevent the rustling of game which was pretty common at the time.

While poaching was a very serious crime, many intruders were undeterred and the game wardens needed more protection in doing their job..

Enter the Gamekeeper’s Night Dog, as the Bullmastiff became known. A large muscular dog weighing up to 130 pounds and standing up to 27 inches  is definitely capable of  making quite an impression on potential trouble makers!

Characteristics

Today, having left his original job far behind him, the Bullmastiff dog breed has moved on to a less stressful role as a cherished family member, who enjoys companionship.

The Bullmastiff is know for his intelligence and alertness. These attributes, along with being a very confident dog has earned him the reputation as a vigilant and fearless family protector.

That being said, you'll be glad to knowhe's not a nuisance barker.

That being said, while Mastiffs make great family companions, being both gentle and affectionate, they do need early training and socialization due to their large size and protective nature. This is crucial and bears repeating as they can be strong willed, even as a puppy.

Activity Level

Daily exercise is a must for all dogs and Bullmastiffs are no exception. They do enjoy a brisk walk but the duration can vary between dogs, some being naturally less active than others.

Exercise should not be excessive while puppies are experiencing fast growth spurts to avoid undue stress on developing bones.

Outdoor play can in a secure area can also be a fun part of their routine.  

Bullmastiffs, being an agile breed, do well in other activities including agility which could be an ongoing experience for both dog and pet parent to enjoy..

For mentally stimulating this intelligent dog, look into obedience, rally, even scent work and tracking and start them young.

Coat and Grooming

The Bullmastiff has a short coat that comes in fawn, red, or brindle.

Monthly routine grooming with a hound glove will suffice. Also clean up the facial folds and ears, brush his teeth and clip nails when necessary.

This breed is a drooler, so you will need to be prepared to handle this in your own way.

Health Notes

Health issues common to large breeds include hip and elbow concerns as well as bloat – a very important life-threatening condition to be aware of.

Overall care of the Bullmastiff should include regular exercise, sound nutrition, and veterinary check-ups on an annual basis to maintain health and a contented life.

Cane Corso

The Cane Corso, also referred to as the Italian Mastiff, is a breed which originated in Italy with a history that goes back to Roman times To be clear, this breed is the result of Italian native dog breeds crossed with Mollosus (mastiff) type dogs obtained during the Roman occupation of the Greek Islands. 

Subsequently, after all the fighting was over in the Western Empire, the dogs took on other jobs around farmhouses including herding or guarding cattle and pigs, wild boar hunting, as well as protecting their owners property. 

Overtime, their numbers diminished greatly that they almost vanished, but were brought back from near extinction by a group of fanciers in the 1970s. A Society of Cane Corso Lovers was formed in 1983.

Appearance:
The Cane Corso has a short dense coat seen in black, gray, fawn, or brindle. The breed is very muscular and can weigh between 100-120 pounds with a height of up 28 inches tall at the withers. Their ears are often cropped.

Characteristics:
A loyal and protective breed that likes to keep in close touch with their owners and other family members most of the time. This also means, they don't like being left alone!

Training can be pretty straightforward if an owner has a strong background in dog training because the CC is very intelligent but can have the tendency to try to take charge.  The solution to this tendency is an experienced owner to provide firm guidance and thoroughly socialize the Cane Corso to build their comfort level around people, places and multiple situations - from a very early age.

Daily Activity:
In addition to a large outdoor area for play, exercise and training, the CC should be taken out for daily walks for his well-being of mind and body.

Health:
Overall the Cane Corso is considered a fairly healthy breed. That being said, there are some health issues associated with them. Those include:

• Hip dysplasia,
• Idiopathic Epilepsy,
• Mange,
• Eyelid issues, and
  
• Bloat,  owners need to know the signs of this life threatening condition
  

AKC Recognition:
The Cane Corso Came to America in 1988, and in 2010 the breed was recognized by the AKC as part of the Working Group of dogs, or Mollosus breeds .

Dogue de Bordeaux

Originating in France, the Dogue de Bordeaux (DDB), is a large breed originally used as guard dogs and later to drive cattle as well as for hunting purposes.

Despite their formidable appearance, Dogue de Bordeauxs are generally gentle and affectionate with their families.

They are loyal, protective, and often described as "nanny dogs" due to their love for children. However, they can be stubborn and require a confident leader who can provide firm and consistent training from an early age.

Proper socialization is also important to ensure they are comfortable in a variety of situations, places, around strangers and of course other dogs.

Dogue de Bordeauxs require a lot of space and exercise to stay healthy and happy.

Health:
Issues that may affect this breed during their lifetime include hip dysplasia and heart conditions, which can be managed through regular veterinary care .and proper nutrition.

Sadly, they have a relatively short life of between 5-8 years.

Proper socialization is an important part of the EM's handling to make sure they are comfortable around strangers and other dogs.

Space Needs:
As can be expected, the English Mastiff's large size is best suited to a lot of space where he can get some daily exercise in addition to daily walks.

Health:

• Hip dysplasia
• Bloat

The latter is a very serious issue which you can learn more about here.

Pyrenean Mastiff

The Pyrenean Mastiff is an ancient breed descended from molosser type dogs believed to have been brought by the Phoenicians to what is now Spain some 3,000 years ago.

It was developed as a livestock guardian breed along with many similar mastiffs bred for the same purpose, such as the Spanish Mastiff, and the Pyrenean Mountain Dog, also known as the Great Pyrenees.

Because the herds of sheep occupied areas populated by large numbers of wolves and bears, these livestock protectors were highly esteemed for the job they performed.  For their own protection, they were fitted with spiked collars around their necks for encounters they may have with wolves and bears.

Over the years, with the introduction of mechanized transportation to move animals, the disappearance of predators, plus the occurrence of various wars, the mastiffs almost became extinct. Fortunately, some fanciers came to the rescue to revive the Pyrenean Mastiff. 

While they are still considered a rare breed, their numbers have increased significantly around the world.

The Pyrenean Mastiff was recognized by the AKC (American Kennel Club) in 2014 and placed in the Working Dog Group.

• Bloat, a life-threatening condition common to large dogs with deep chests.
• Elbow and Hip Dysplasia
• Eye Conditions such as Entropion

Exercise:
Coming from a outdoor working background, the Pyrenean ideally needs a large outside area to roam about in and sniff around. In addition, for his health and mental stimulation he should have a daily walk of up to an hour.

With Children:
Providing they have been properly socialized, Pyreneans have a natural affinity for children.

Despite their large size, they are very gentle and patient with even with boisterous little ones. However, children should be taught how to interact with pets and not tease or take advantage of their good nature.

South African Mastiff

History of the rare South African Mastiff (SAM), commonly known as the Boerboel, has its roots deeply embedded in South Africa. This breed was initially developed by early settlers, including Dutch, French, and German colonists, who needed a robust and versatile dog to help with a variety of tasks.

These mastiffs were bred for guarding homesteads, protecting livestock, hunting large game, and driving cattle. Their lineage includes the Mastiff-type dogs brought by these settlers and local indigenous breeds, resulting in a dog well-suited to the demanding conditions of South African farms and ranches.

Appearance:
South African Mastiffs (SAMs) are imposing and muscular dogs with a commanding presence.

Height: Males 27 inches, Females 25 inches
Weight: 150-200 pounds

They possess a short, dense coat that comes in colors such as fawn, brindle, and black. Their broad head is adorned with a strong jaw and, in some cases, cropped ears, though ear cropping is less common today and often considered unnecessary. Their build is robust, with a deep chest and well-defined muscles that reflect their strength and agility.

Characteristics:
South African Mastiffs are known for their formidable presence and natural guarding instincts. They are inherently protective of their family and territory, which makes them excellent guard dogs.

Despite their formidable appearance, they are typically calm and gentle with their families. They exhibit loyalty and affection, along with a patient and composed demeanor.

Training and socialization from an early age are crucial to manage their protective instincts and ensure they are well-adjusted and sociable. These dogs are intelligent and can be independent, so a firm yet gentle approach to training works best.

Exercise:
Boerboels are active and require regular exercise to stay healthy and content. They enjoy activities that engage their strength and stamina, such as daily walks, playtime in a secure yard, and mental stimulation through training exercises or interactive toys.

While they are generally low-key indoors and appreciate lounging around the house, they do need opportunities to expend their energy.

Their exercise needs should be balanced to prevent obesity and maintain their physical fitness, especially given their predisposition to certain joint and digestive issues.

Health Notes:
The South African Mastiff has a life expectancy of 9 to 11 years with the benefit of good care.  Like many large breeds, the SAM is prone to specific health concerns. Common issues include:

• Hip dysplasia, a genetic condition that affects the hip joints
• Bloat, a potentially life-threatening condition causing the stomach to expand and twist.

Regular veterinary check-ups, a balanced diet, and maintaining a healthy weight are essential to manage these risks. Early screening and proactive health care can help mitigate some of these issues, ensuring a longer, healthier life for the breed.

With Children:
While South African Mastiffs can be loyal and protective companions, they may not be the best choice for families with very young children. Their size and strength can inadvertently lead to accidents, especially if the dog is not well-trained or socialized.

However, with proper training and supervision, they can get along well with older children, who have familiarity with large breeds and are respectful of them. 

While the SAM has a gentle nature, it’s important for interactions between the dog and children to be monitored for the safety of both.

Key Points:

• Requires early training and socialization.
• Needs regular physical activity
  
• Prone to hip dysplasia and bloat; requires regular veterinary care and proper nutrition.
• Best suited for families with older children due to their size and strength.

The South African Mastiff is a powerful and devoted breed that thrives under the care of a knowledgeable owner. Their loyal nature and protective instincts make them excellent companions for the right environment, where they can receive the attention, exercise, and training they need.

Spanish Mastiff

Spanish Mastiffs With Family

Based on the Spanish Mastiff's history as a working breed, it is not surprising that protecting their family comes naturally to them. This large breed is very confident and aware of its power when it comes to potential threats.

While the SMs are not frequent barkers, they will use their their commanding loud bark to alert you to unusual situations or approaching strangers.  I think this would also tend make visitors take a wait and see approach!

They have a moderately good reputation with children as well as other pets

Spanish Mastiffs have a calm and patient demeanor and without doubt are very loyal and affectionate with their families.

Training

Because the Spanish Mastiff is a powerful and protective breed, training is vitally important starting from an early age.

They require a firm and experienced owner who can properly train and thoroughly socialize with positive reinforcement methods from an early age. Well-rounded socialization that exposes them to people, places, situations, as well as other dogs, will help balance their protective nature.

This will ensure they become the great companions you want them to be.

Potential owners are advised to research and understand the breed thoroughly before inviting one into their home. They can make a great companions for the right family, but they are not recommended for novice dog owners and do best in homes without small children or other pets. Older children, familiar with and respectful of, pets are an exception.

Exercise and Health

Spanish Mastiffs should have more than one daily walk as well as other forms of exercise including outdoor games, in a fenced area which ideally gives them space to roam. Other ways to provide more activity include swimming, hiking, and dog sports like agility.

In the home but they are generally mellow dogs that are happy to lounge around the house with their owners.

Spanish Mastiffs are associated with certain health issues, such as hip dysplasia. Bloat is another serious condition that owners need to watch out for because is common with large chested dogs and needs immediate attention should it occur.

Dogs with the possibility of bloat can have their food placed in special bowls designed to slow down their eating.

Expected lifespan is 10-12 years with good care and regular veterinary health checks.

Spanish Mastiff - Takeaway

Before deciding on this large breed dog for your family, do thorough research so you don't miss any of the important details.

• Try to have conversations with others who have had a Spanish Mastiff or are very well-informed about the breed.
• Find some experienced professional breeders who can supply references from previous sales of puppies.
• Be sure you can accept a dog that drools!

Tibetan Mastiff

The Tibetan Mastiff is an ancient mastiff dog breed that originated in Tibet, China and is a real mountain dog who enjoyed a homeland in the high Himalayas and plains of Central Asia. This mastiff breed was also a known breed in Syria and Arabia.

Tibetan Mastiffs are one of the oldest true mastiffs and believed to be the stock from which all mastiff or Molosser breeds and all mountain dogs were developed. In Tibet they are known by the name Do-Kyi (tied Dog) which relates to being tied to the gates of properties and temples.

Later when Queen Victoria received one, it was just identified as a large dog from Tibet. Subsequently, it was officially named by the Kennel Club as Tibetan Mastiff for the first time.

Historically, the TMs were bred to guard properties and protect flocks of sheep from predators like wolves and snow leopards.

In Tibet, they are tied outside the home during the day and allowed to run loose at night to protect the property. The Tibetan Mastiff is considered a primitive breed.

The Tibetan Mastiff is one breed that is very expensive to acquire. In March of 2011, it was reported that a TM named Hong Dong was purchased by a wealthy gentleman in China for the sum of $1.52 million! Obviously this rare breed is not one that many individuals could afford.

In 2006, the TM was made a part of the AKC's Working Group, but it was
President Eisenhower who is known to have received one of the first Tibetan Mastiffs in the United States as a gift in 1958.

Characteristics of the Tibetan Mastiff

Due to their history as guardians, Tibetan Mastiffs are naturally protective of their families and can be wary of strangers. While their appearance may be intimidating, they would not be aggressive without cause.

Their powerful appearance and size alone would be a deterrent to someone thinking about trespassing.

Despite their natural guarding instincts, loyalty and affection with their families, they are known for their, gentleness, calm and patient demeanor.

However, to help them thrive, this powerful dog requires a firm and experienced owner who can provide the training, exercise, and early socialization they need.

While the Tibetan Mastiff is very intelligent, training can be challenging due to the TM's independent streak. After all, he had to be the decision maker for a long time!

The TM likes being close to his pack and can make a great companion for the right family, but they are not recommended for novice dog owners.

Appearance

Tibetan Mastiffs are some of the largest dogs in the world, with males weighing up to 160 pounds and standing up to 29 inches tall at the shoulder by the time they are 18 months old.

Marco Polo is said to have described them as the size of a small donkey.

They have a thick, long coat that comes in a variety of colors, including black, brown, and blue-gray. Tibetan Mastiffs have expressive brown eyes and broad head that is set high and surrounded with a thick mane of fur and a strong jaw.

Shedding of this double coat is above average, but twice a year it sheds very heavily, usually spring and fall. Maintenance of the coat will vary according to the time of year, but is important to keep up to avoid mats and skin issues.

 

Exercise

Tibetan Mastiffs do not need a lot of exercise and this is especially true during the first 18 months of growth development.

After they have fully matured, a moderate daily walk will be enjoyed.  They are relatively inactive while indoors and happy to lounge around the house.

An outdoor space to roam and sniff around is appreciated.

Health Notes

Tibetan Mastiffs are prone to certain health issues which pet parents should become familiar with. They include:

• Hip dysplasia. This is a painful condition causing a loosening of the hip join.
• Hot spots. Dogs of this breed frequently experience acute dermatitis, commonly referred to as hot spots.
• Ear infections.
  
• Eye Disorders such as Entropion and Ectropion.
  
• Hypothyroidism. This condition occurs due to an under-active thyroid gland and results in hormonal imbalance.
• PRA - Progressive retinal atrophy. A degenerative inherited eye disease which can lead to vision loss or blindness.
  

Pet parents may expect their TM to live up to 12 years with the benefit of a high quality diet, moderate exercise and regular oversight from their veterinarian. Individual lifespans can differ based on genetics and overall care.

Extinct Mastiff Dog Breeds

Cuban Mastiff

The Cuban Mastiff, also known as Dogo Cubano, Cuban Bloodhound or Cuban Bullmastiff, is an extinct breed which existed in the early 1800's.

It was developed in Cuba from bulldogs, mastiffs and cattle dogs which resulted inthe breed bearing a resemblance to the Bullmastiff.

This breed was mainly used to guard properties or as watchdogs and there is some indication they may have participated in bull-baiting or dog fighting as it fits into the profile of dogs in these type activities.

According to Wikipedia, the breed was introduced into Cuba to capture runaway slaves. Subsequently, when slavery was abolished, they ceased to exist.

Alpine Mastiff

A breed originating in Switzerland that became extinct during the 19th century.

This breed bears a strong relationship with some of today's mastiff breeds. It was also among those which contributed to the development of the St. Bernard.
