If you are looking for a large, powerful dog, but you also want an animal who is unique, one of these rare mastiff dog breeds may be exactly what you are looking for. These are impressive, big dogs who can bring the love along with their size. Each breed has unique characteristics and care requirments, so find out which might be a good fit for your home.

Rare Types of Mastiffs

Mastiffs are a group of large, working-type dogs that include a number of varieties. Some are recognized as individual breeds, while others are still working toward recognition. A number of these dogs are even quite rare in their own home countries.

Mastiffs come from all over the world, and although they are similar to each other in many ways, each has subtle differences due to where the breed originated and the purpose it was bred for. Examples of the most rare Mastiff breeds include:

Andronicus Mastiff

Dog Sitting On Field Against Trees

The Andronicus Mastiff is a bit of a mystery, and there are very few facts known about it. According to MolosserDogs.com, this rare Mastiff was developed by Cary Mejia of California. Mejia has kept the secret of the breeds used to develop the Andronicus, but interested parties speculate that the following dogs were used as the foundation for the breed.

Because so many breeds have possibly contributed to the Andronicus' genetic makeup, there's a lack of uniformity in their appearance. Some look like super-sized American Staffordshires, while others have a more traditional Mastiff look. The one aspect they all have in common is that they are powerfully built and have strong jaws. Mejia provides an gextensive gallery you can view on his website. He does state that males typically weigh between 100 and 140 pounds, while females are a little smaller at 80 to 110 pounds.


According to Mejia's own website, Andronicus.com, this dog's personality is described as:

  • Sweet and devoted
  • Not headstrong like some Mastiffs tend to be
  • Respectful of your authority
  • Good with children


An Adronicus Mastiff was featured in the movie, The Hulk. This raised awareness of this dog's existence and created some demand for puppies. Currently, Mejia sells puppies for a minimum of $2,500, and only male pups are made available to the public. Mejia keeps all the females for the breeding program, and states that if anyone else tries to sell you an Andronicus, it's not the real thing.

With all the hype that surrounds this Mastiff, it will be interesting to see what becomes of it in the future. Perhaps one day it will achieve full-breed status, but for now, it is simply one more designer breed.

Tibetan Mastiff

Unlike the Andronicus, the Tibetan Mastiff is a full-fledged breed after gaining recognition from the American Kennel Club (AKC) in 2006. Even though that recognition is relatively recent, the breed dates back as far as 1100 B.C. China. These dogs were developed primarily to guard their families.


According to the AKC Breed Standard, these dogs:

  • Stand 24 to 26 inches tall at the withers
  • Are slightly longer than they are tall
  • Are extremely muscular and solidly built
  • Have very broad, strong heads
  • Have well-feathered tails held curved up over their backs
  • Have thick coats with heavy manes and a lot of feathering on their britches

The AKC describes the breed's temperament as:

  • Reserved and aloof with strangers

Since this breed is so rare, locating a breeder can be a challenge. To find a list of reputable breeders, visit the American Tibetan Mastiff Association.

Neapolitan Mastiff

The Neapolitan is another rare Mastiff that is ancient in origin, but was only recently recognized by the AKC in 2004. The breed traces its lineage back to the Roman dogs of war. Its intimidating looks were specifically designed to enhance its guard dog status. Today, the Neapolitan is a quiet family dog that doesn't bark unless it seems necessary, but it still makes an outstanding guardian.


According to the AKC Beed Standard, these dogs:

  • Are massive and heavy boned
  • Have thick tails that taper toward the tip and are docked by 1/3 of their original length
  • Are covered in loose skin
  • Have large heads draped in voluminous wrinkles
  • Are naturally heavy droolers due to their very loose jowls

  • Stand 24 to 31 inches tall at the shoulders

Sometimes people take on one of these dogs without fully realizing what they're getting into. If you're interested in finding a Neapolitan companion, consider visiting Mastino Rescue.

Alangu is the name they mainly go by in India, where it is believed they originated, while Bully Kutta is the name given to them in neighboring Pakistan.

The Presa Canario, as it is commonly referred to, was developed in the Canary Islands sometime during the 1800s. These dogs worked hard guarding livestock against predators, and they also helped catch and hold livestock. Unfortunately, some were also used as fighters. The breed went into serious decline for a time, but breeders began working diligently in the 1970s to preserve it.

  • Docile and obedient to its owners
  • Wary of strangers
  • Aggressive toward other dogs

Mastiff Crosses

There are several Mastiff crosses that are desirable, including:

  • Irish Mastiff: The Irish Mastiff is a mix between the English Mastiff and Irish Wolfhound. The Irish Wolfhound adds some extra sweetness to the loving English Mastiff's already friendly demeanor.
  • Bloodhound Mastiff: This pooch is a blend of the Bloodhound and English Mastiff. With the Bloodhound's keen sense of smell, and the English Mastiff's kind disposition, this breed could make an excellent addition to the family.
  • Ambullneo Mastiff: A mix between the English mastiff and Neapolitan Mastiff creates this designer breed. These breeds have been crossed for generations, allowing the genetic problems that existed prior to be filtered out down the line.
  • Shepherd Mastiff: This is a mix between the German Shepherd and the English Mastiff. This breed mix isn't as popular due to their stubborn streak, but once trained, could make a large protective guard dog for your family.
  • Mastidoodle: The Mastidoodle is a cross between the Mastiff and Poodle. Developed in the 1990s, this breed hybrid is commonly chosen due to their hypoallergenic trait.


These dogs need very strong leadership from their owners to become good household companions. Visit the UPPCC website for a list of registered breeders and available puppies.

Are You the Right Person for a Rare Mastiff?

Rare Mastiffs, like all mastiff breeds, require a good deal of space and a handler who has working experience with large dogs. These huge dogs need to be socialized when they are young puppies to circumvent any problems later when the dog is large and more difficult to handle. Like other rare breeds, these unusual mastiffs will command top prices. If you are planning on getting a mastiff, be sure to learn all you can about the particular breed you're interested in. Before making a final decision, talk to the breeder to make sure that this type of dog is a good fit for your lifestyle.
