That said, if you are interested in meeting the incredible Mastiff mixes, keep reading! This article lists the popular and seemingly unlikely Mastiff hybrids with all their unique and lovable traits.
43 Mastiff Mixes
The Mastiff, also known as the Old English Mastiff, is an ancient dog breed that initially served as a hunter and war dog.
Although it is a fearless protector, it is likewise a well-loved family pet due to its gentleness and loyalty toward its loved ones.
When paired with another breed by reputable breeders who wish to improve the Mastiff’s characteristics, a one-of-a-kind mix is produced. This bears the blended physical traits and personality attributes of the Mastiff and the other parent breed.
With that, let’s take a look at the 43 remarkable and unique Mastiff mixes:
1. American Masti-Bull
Parent Breeds: American Bulldog & Mastiff
As a confident protector and gentle, loyal family pet, the American Bulldog Mastiff mix, or American Masti-Bull, bears an intimidating yet cuddly dog appeal.
You’ll mostly see American Bulldog Mastiff mixes sporting a brindle coat pattern. But, they can also come in other coat colors similar to the Mastiff and American Bulldog.
This mixed breed, weighing between 60 and 230 pounds, can seem menacing with its strong and well-muscled physique.
But at the same time, the kind temperament, patience, and devotion the Mastiff American Bulldog mix has for its loved ones make it a genuinely endearing family member.
In addition, the Mastiff American Bulldog mix is not one to bark unnecessarily as it inherits the quiet tendencies of the Mastiff and American Bulldog.
As such, whenever this mix barks, it is only usually trying to alert its owners of any perceived threat or intruders.
Parent Breeds: Boxer & Mastiff
The patient and protective Boxer Mastiff mix is an outstanding family guardian with a lively personality. These energetic hybrids simply adore their human pack and are especially great with children.
A distinct black mask is part of the trademark look of the Boxmas. It is likewise common to see these canines with fawn and brindle coat colors.
In addition, this large mixed breed can stand anywhere from 23 to 36 inches in height.
Like the Mastiff dog, the Boxer Mastiff mix is vigilant and fearless in defending its loved ones. At the same time, its playful nature makes it always eager for fun activities with its family.
And because it can get very attached and protective of its family, it is important that this mix be properly socialized early on to help it get accustomed to being around strangers.
Parent Breeds: Great Dane & Mastiff
The Daniff, otherwise called the Great Dane Mastiff mix, is an alert family guardian that is also calm, affectionate, and patient.
This unique pairing of the purebred Great Dane and the Mastiff breed produces a laid-back family member that enjoys downtime spent with loved ones.
While it appreciates a laid-back lifestyle, this mix also gladly welcomes playtime and fun adventures with its humans.
And though it is an easygoing canine, this Mastiff mix takes its home guardian role seriously. This hybrid will courageously protect its loved ones from any ill-intentioned individuals.
My experience in dog handling has made me encounter the Daniff multiple times, and this is one of the largest hybrids I’ve had the opportunity to handle. They sometimes appear as thicker Great Danes or taller Mastiffs.
Regardless, the Great Dane Mastiff mix bears the dignified and elegant appeal of its parents. I can vouch that its massive size alone clearly gets the job done of intimidating intruders.
Further, this gentle giant can have many beautiful coat variations — from brindle and apricot like the Mastiff to blue, black, and harlequin, like what can be observed in Great Danes.
Parent Breeds: Bullmastiff & Mastiff
The Doubull-Mastiff is a hybrid of two mastiff breeds such as the Bullmastiff and the Mastiff. The combination of these two dog breeds produces an ultimately fearless, powerful, and loving family companion.
As a descendant of two mastiff breeds, the Doubull-Mastiff is an extra-large canine that is alert and protective.
With its mere size and appearance, meeting one in person can be an intimidating experience for many. But for those who are considered part of its pack, the Doubull-Mastiff is a sweet fellow who is anything but scary.
That said, training this mix is very crucial due to its size and strength. Proper manners and good behavior must be instilled during the puppy years.
It can take a fair amount of patience, consistency, and assertiveness to successfully train a Doubull-Mastiff due to its independent streak.
With that, potential owners must carefully assess their capabilities before getting one.
5. Englian Mastiff
Parent Breeds: Neapolitan Mastiff & Mastiff
If you are looking for a large dog that can serve as an exceptional guardian of your home, you have to meet the Englian Mastiff. This large mixed breed is a cross between the Mastiff and the Neapolitan Mastiff.
An Englian Mastiff has a calm demeanor and is immensely loyal to its humans, like its parent breeds. It is a dedicated and powerful defender, which makes it naturally suspicious of unfamiliar people.
Its dignified appearance is reflective of its formidable strength, standing between 24 and 31 inches in height and weighing around 110 to 230 pounds.
It can also have wrinkly skin all over its massive body, which is a distinct trait of the Neapolitan Mastiff.
Meanwhile, due to the loose skin around its large lips, Englian Mastiffs tend to drool a lot. As such, tying a bandana around its neck can help keep your floors free from saliva.
6. Irish Mastiff
Parent Breeds: Irish Wolfhound & Mastiff
As a cross between the Irish Wolfhound and the Mastiff, the Irish Mastiff is a reaffirmation of its parents’ greatest traits.
This hybrid, also known as Irish Mastiff Wolfhound, is a dignified, calm, and courageous family companion.
It is an extra large dog that has a regal appeal with its tall stature and gentle aura. It can have a short straight coat like the Mastiff or be like its Irish Wolfhound parent and have a wiry, harsh coat.
In addition, an Irish Mastiff is known to be tolerant and patient with children. It is likewise very alert and can serve as an excellent watchdog of the home.
But, as with many giant breeds, this mix’s lifespan tends to be short. Owners of Irish Mastiffs must make the most out of the limited time they have with this canine, as it can only live for around 6 to 10 years.
Parent Breeds: Labrador Retriever & Mastiff
The Mastador is a mix of the powerful Mastiff and the highly energetic and friendly Labrador Retriever. This delightful hybrid is an extremely loving, gentle, and intelligent family companion.
Having a Labrador parent enables this Mastiff mix to be outgoing and accepting of other people and animals outside its family. It likewise inherits its eagerness and playful spirit from the Lab.
Meanwhile, its Mastiff parent passes on its skills as an exceptional guardian of the family to the Mastador.
This mix also tends to be less active than the Labrador, as it inherits the calm and docile nature of the Mastiff.
When it comes to grooming and maintenance, potential owners must be prepared to allot time to regularly brush the Mastador as this mix tends to shed a moderate to a heavy amount of fur.
Fur shedding likewise increases exposure to dander, making the Mastador unsuitable for allergy sufferers.
8. Mastiff Shepherd
Parent Breeds: German Shepherd Dog & Mastiff
The fierce-looking Mastiff Shepherd is a prized family dog due to its loyalty, intelligence, and affectionate personality. It is a superb protector, thanks to its German Shepherd and Mastiff lineage.
Also known as the German Shepherd Mastiff mix, this crossbreed’s appearance can vary depending on whether it takes more after its German Shepherd or Mastiff parent.
In addition, the Mastiff Shepherd can have apricot, brindle, and fawn coat colors but can also sport several other colors like what can be seen in German Shepherds.
As a dog behaviorist myself, I have had a lot of opportunities to work on training Mastiff Shepherds. Ideally, I would suggest that these dogs undergo proper socialization and obedience training at an early age.
This is because handling a strong dog of immense size can be difficult, especially if it has not learned proper manners and good behavior. Many of the Mastiff Shepherds that I have trained quite late take months to get out of their stubborn phase.
Meanwhile, watch a Mastiff Shepherd transform into a well-behaved canine in the video below:
Parent Breeds: Poodle & Mastiff
The Mastipoo is a remarkable combination of the Mastiff and the Poodle. This smart, lively, and alert mix also goes by the name Mastidoodle.
A Mastipoo is super sweet and cuddly. It never seems to pass up on any opportunity to snuggle with its humans, something many pet lovers are sure to appreciate with this hybrid.
It is also an alert watchdog of the family. Depending on which parent it takes more after, it can be very friendly with strangers like Poodles or may tend to be distant with unfamiliar people like Mastiffs.
Like most mixed breeds, the exact physical appearance of the Mastipoo can vary. It can have the short, coarse coat of the Mastiff or the curly hair of the Poodle.
Its exercise requirements will also depend on whether it tends to be very active like the Poodle or more laid-back like the Mastiff.
10. Mountain Mastiff
Parent Breeds: Bernese Mountain Dog & Mastiff
A gentle giant like the Mountain Mastiff is a dream family pet as it is very strong yet so sweet and calm. Its huge size matches the amount of happiness and love this crossbreed can give.
The Mastiff Bernese Mountain Dog mix is gentle with young kids and tends to do well with other pets. It is also easily trainable, especially when consistent and gentle training methods are used.
In addition, a Mountain Mastiff is also relatively easy to groom, only requiring regular brushing and occasional baths to stay clean and tidy. It can be prone to drool, though, so its mouth needs to be wiped often.
Like many large breed dogs, the Mastiff Bernese Mountain Dog can be prone to bloat. With this, it is best to avoid vigorous activities immediately before and after eating to help keep the Mountain Mastiff healthy.
Parent Breeds: Rottweiler & Mastiff
When you combine the burly and good-natured Mastiff with the confident and faithful Rottweiler, the result is an exceptional Mastweiler that is truly powerful, devoted, and calm.
It is a large companion and family guardian dog that lives to safeguard its humans. A Mastweiler is a strong and well-muscled hybrid that is very alert and clever.
And like the English Mastiffs and Rottweilers, this mix is expressive of its emotions and is devoted and loving towards its family.
Meanwhile, it is crucial for Mastweilers to be socialized and trained at an early age due to their territorial nature. Doing so enables them to live harmoniously with other animals.
Apart from physical activities, a Mastweiler also needs lots of mental stimulation to keep it from becoming bored.
Fun exercises that hone problem-solving skills, like puzzles and obstacle courses, are recommended for Mastweilers.
12. Pit Mastiff
Parent Breeds: American Pitbull Terrier & Mastiff
One of the popular Mastiff mixes is the Pit Mastiff. With its incredible loyalty and profound love for its humans, it’s easy to see why this is a favorite choice for a family companion.
For starters, a Pit Mastiff is a product of pairing a Mastiff with a breed from the Pitbull family of breeds.
This includes the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, and American Bully.
Its physical traits and size can vary, but this crossbreed is ultimately a confident and dignified guardian of its family.
While a Pitbull Mastiff mix can appear to look serious and menacing, this mix has a silly side to its personality, enjoying playtime and bonding with loved ones.
Meanwhile, for a Pitbull Mastiff mix to get along well with other pets, it must be socialized at a young age.
13. Saint Bermastiff
Parent Breeds: Saint Bernard & Mastiff
The Saint Bermastiff is one of the gentle giant crossbreeds. This charming Mastiff and Saint Bernard mix is a gentle yet fearless family companion.
As one of the gentle giants of the canine kingdom, the Saint Bermastiff is a family’s big companion with its sweet temperament and patience for little children.
Furthermore, Saint Bermastiffs are also great watchdogs as they are alert and brave. They do well with other dogs and animals, especially when accustomed to living with them at a young age.
Some owners of massive breeds think that their dogs need rigorous exercise. However, as a dog handler for more than 10 years, I can validate that such huge breeds like the Saint Bermastiff will be content with daily walks with their humans to fill their daily energy needs.
Meanwhile, as a giant breed, the Saint Bermastiff’s short life expectancy is only around 6 to 10 years.
Owners must ensure their good health by being wary of any signs of health problems such as bloat, heart disease, and cancer.
14. Akita Mastiff Mix
Parent Breeds: Akita & Mastiff
The Akita Mastiff mix is a large dog with a friendly and dignified demeanor. This mixed breed is courageous and very loyal to its family, being an offspring of the Japanese or American Akita and the Mastiff.
On average, an Akita Mastiff can live for 6 to 13 years. It has an improved chance for a longer lifespan compared to the Mastiff, thanks to its Akita parent.
As both its parents are excellent protectors of their loved ones, the Akita Mastiff mix naturally follows suit with being a good guard dog.
With that, early training and socialization are very crucial for the Akita Mastiff mix due to its huge size and strong guarding instincts.
Meanwhile, grooming this hybrid is a pretty easy task as it does not require regular coat trimmings. A weekly brushing routine is enough to help maintain the beauty of its coat and keep it healthy.

The Alaskan Malamute Mastiff mix is a mixed breed that is affectionate, good-natured, and playful. It likewise has a strong work ethic, having parent breeds who are both from the working group.
This mix is capable of performing diverse tasks, such as being a good guard dog, a skilled worker in search and rescue missions, and police and military work, like the Mastiff.
At the same time, it can also be a competent sled dog like the Alaskan Malamute, given the proper training and the opportunity to showcase its skills.
In my years of handling different dog breeds, I have observed most of the Alaskan Malamute Mastiff mixes I have handled have a high prey drive. While this mix can be great with kids, owners must have secured fenced yards to prevent this mix from suddenly chasing small animals.
This behavior is something that I have mostly observed in purebred Alaskan Malamutes, as well. Hence, to make it easier for owners to handle this large hybrid, I recommend subjecting them to early socialization and obedience training.
