Among all of the mixed-breed dogs out there, the Boxer Mastiff mix stands out with its unique appearance and balanced temperament.
This hybrid dog is a crossbreed of the loyal and elegant Boxer dog and the gentle-natured large breed, the English Mastiff.
If you want to learn more about this curious mix, I suggest you stick around.
This guide will dig deeper into the history and background of the Boxer Mastiff mix, as well as their appearance, temperament, and common health issues. Let’s start!
What Is a Boxer Mastiff Mix?
The Boxer Mastiff mix, also known as Boxmas and Mastiff Boxer mix, is produced by crossbreeding a Boxer with a Mastiff. It is a large-sized dog that can grow as big as its parent breeds. Unsurprisingly, the Boxmas dog inherits its parents’ active, vigilant, yet friendly traits.
Boxmas dogs look like pumped-up Boxer dogs. Most of them inherit the outer appearance of the Boxer breed but grow as big as the giant Mastiff breed.
Although they are not mean like their Boxer parent, the Boxer Mastiff mixes are not recommended for families with toddlers. The sheer size of these mixed-breed dogs could easily sway off a toddler unintentionally.
Nevertheless, if you have an active lifestyle and are looking for a workout buddy, the Boxmas dog might be just the right dog for you. This hybrid dog is highly energetic and loves playing and exercising.
The Boxer Mastiff mix is also a great candidate for a guard dog. It has inherited its parent breeds’ watchful traits and guarding instincts.
Boxer Mastiff Mix Origin and History: Where Does the Boxmas Come From?
So far, no records are available that could prove the date of development and origin of the Boxer Mastiff mix.
However, we can still have a sneak peek of the Boxmas’ background by looking into its parents’ histories.
Both of the Boxmas’ parent breeds (the Boxer and English Mastiff) are fierce and brave working dogs.
The Boxer breed came from the bloodline of war dogs that dates back to 2,500 BC. The sleek and elegant Boxer that we know today was developed in the 1800s in Germany.
Since the breed’s development, Boxer dogs have served various jobs. They have been used as war dogs, police dogs, guard dogs, cattle dogs, watchdogs, guide companions, and protection dogs.
The Boxer breed was registered in the American Kennel Club (AKC) only in 1904.
Meanwhile, the noble giant we know as English Mastiff also has a fierce history. This dog breed was also once used as a war dog. Because of its protective nature, it was also bred to be a guard and hunting dog during the medieval era.
Hence, it’s not surprising that the Boxer Mastiff mix is a protective canine, just like their English Mastiff parent. Their protectiveness, however, should not be confused with aggression.
Protective dogs will only act to defend themselves and their families in certain situations where danger is imminent.
Boxer Mastiff Mix Appearance: What Does a Boxmas Look Like?
If it takes after its Boxer parent, it will exhibit the identifiable features of the Boxer breed — drooping skin folds in the cheek, black nose, and brown eyes. They will also have medium-length ears.
Meanwhile, a Boxmas that takes after its Mastiff parent dog will inherit the wrinkled brows and droopy jowls of the Mastiff breed.
Most Boxmas fall between the weight and height ranges of the Boxer and Mastiff dog breed.
However, it is not unusual to see Boxmas mixes that are significantly huge in terms of height and weight, especially when they inherit more traits from their Mastiff parent. They also have a muscular and intimidating body structure.
The coat of the Boxmas mix is short, dense, and waterproof. Its common coat colors include fawn, black, and brown, although it can exhibit almost any of the coat colors of its parent breeds, including white and brindle.
In general, most Boxmas puppies grow up having Boxer faces with Mastiff body frames.
Boxer Mastiff Mix Size and Weight: How Big Do Boxer Mastiff Mixes Get?
The Boxer Mastiff mix is a large hybrid dog that typically stands between 23 and 36 inches tall.
In terms of weight, this gentle giant can weigh between 70 and 100 pounds, making it one of the largest mixes in the canine community.
Most Boxmas mixes inherit their large body frames from their Mastiff parent dogs, which is a large breed.
In general, male Boxmas mixes grow a little bit taller and heavier than their female counterparts.
At the age of 18 months, Boxmas mixes are already considered to be fully grown. They should already have reached their full-grown size and weight during this age.
Nevertheless, they could still gain a few more inches and pounds as they grow old, depending on their diet and lifestyle.
Boxer Mastiff Mix Temperament: Do Boxer Mastiff Mixes Make Good Family Dogs?
Boxer Mastiff mixes are loyal, affectionate, protective, and courageous dogs. Overall, they can make good family pets. However, one should know that they are not for everybody.
The Boxmas breed is an energetic, playful, and cheerful hybrid. It surely loves mingling with its family but can sometimes be stubborn because of its strong-willed personality.
However, it’s not the type of dog recommended for beginner dog owners.
If you already have experience owning a large dog and have an active lifestyle, the Boxmas could be a good pet for you. It is an active breed which means it would appreciate daily activities and playtime.
The gentleness and loyalty of this giant dog towards its family members and children are of no question. It is also protective of its pack.
Boxer Mastiff dogs are calm and gentle around strangers and other dogs, but they remain reserved.
These mixed-breed dogs do not also bark a lot. They will only bark occasionally to alert their owners when they sense danger or see suspicious animals or strangers.
Nevertheless, the Boxmas mix is not recommended for families with toddlers. The weight of this hybrid could easily knock off a toddler unintentionally.
It is also important to socialize your Boxmas at a young age. It should be taught how to distinguish between a friendly stranger and an intruder.

Boxer Mastiff Mix Lifespan and Health Issues: Are Boxer Mastiff Mixes Healthy Dogs?
Aside from its long lifespan, the Boxer Mastiff mix is also a healthy crossbreed. Like other mixed breeds, the Boxmas dog enjoys the benefit of the hybrid vigor.
Nevertheless, this does not mean that they are immune to illnesses and injuries. Boxmas mixes also suffer from common health issues that could affect the quality and length of their lives.
Here are some of the common health issues of the Boxer Mastiff mix:
- Hip Dysplasia: This joint-related disease is typical for large-size dogs. It is a debilitating illness that affects the joints of a dog in the hips. A Boxmas mix suffering from hip dysplasia will show signs such as weakness, lameness, pain, limping, and reluctance to move.
- Brachycephalic Syndrome: This health issue affects the airway of brachycephalic dogs or short-snouted dogs. Boxmas mixes with short snouts like their Boxer parents may fall victims to this disorder. The brachycephalic syndrome causes difficulty in breathing, leading to more severe complications.
- Degenerative Myelopathy: This degenerative disease that affects the spinal cord can progressively weaken the limbs of a dog or, worse, paralysis. Early clinical signs of this disease include walking on knuckles, swaying of hind legs while standing, weakness of limbs, and difficulty standing.
- Wobbler Syndrome: This neck disease is common for large dog breeds. The anomaly with the nerves in the spinal cord results in nervous system deficits. Boxmas mixes suffering from this disease will show signs such as neck pain and uncoordinated gait of the hind legs.
- Hypothyroidism: Boxer Mastiff mixes inherit this disease from their Mastiff parents. The thyroid glands of dogs with hypothyroidism do not produce enough hormones called thyroxine, which is essential for metabolism. Common signs of this disease include hair loss, skin irritation, muscle loss, and sluggishness.
Through proper care and maintenance, you can lower the chance of your dog acquiring the above-listed health issues. A regular visit to the vet will also go a long way in prolonging the life of your dog.

How to Take Care of Your Boxmas
Maintaining and caring for a Boxmas is pretty simple. This large-sized hybrid only needs a nutritious diet, regular grooming, an active lifestyle, and tons of love to have a happy and healthy life.
In this section, I will discuss the different needs of a Boxer Mastiff mix as it grows. Hopefully, this will help you in taking care of your Boxmas dog.
Food and Diet
Since Boxmas mixes are large-sized dogs, you should expect that they also have large appetites. These hybrid dogs should be fed four cups of high-quality food a day.
You also need to ensure that the dog food you feed your Boxmas contains essential nutrients for muscle building and energy replenishment.
They are energetic dogs, so they need food specifically made for large and active canines.
Nevertheless, be careful not to overfeed your Mastiff Boxer mix as it can become obese. Strictly following a feeding schedule can help develop good eating habits for your dog.
You can also opt for healthy treats such as steamed or raw veggies and fruits instead of commercially available dog treats.
Cleaning and Grooming
Boxer Mastiff mixes are a breeze to groom. They have a short, dense, waterproof coat that is easy to clean and brush. Weekly brushing can help in managing the sheddings of your Mastiff Boxer mix.
You should also bathe your dog at least once a month to remove the dirt in its body and the foul canine smell.
Ears, paws, and body pits should also be thoroughly cleaned as ticks and fleas love hiding in these areas. The nails of Mastiff Boxer mixes should be clipped monthly.
Lastly, you should also brush the teeth of your Mastiff Boxer mix at least three times a week, according to VCA Animal Hospitals.
Training and Exercise
The Boxmas dog is a highly energetic breed. Hence, it requires regular activities and stimulation to keep it contented and entertained.
On average, you should allot an hour daily to exercise and keep your Mastiff Boxer mix stimulated. This could be in the form of playing or walking in the dog park.
You should never leave your Mastiff Boxer mix bored and unattended as it could resort to destructive behavior such as barking and chewing things.
This gigantic hybrid is highly intelligent. It is easy to train but can also be quite stubborn sometimes. A Boxmas puppy should have early training to temper its protective instincts.
