The History Of the Mastweiler

The history of the Rottweiler English Mastiff Mix is a bit of a mystery. Unfortunately, there is no proper documentation of the Mastiff Rottweiler Mix’s history. 

Hybrid dogs’ histories and records are often hard to read and decipher. However, we can piece together a rough timeline of the Mastiff Rottweiler Mix’s history based on the history of its parent breeds – the Rottweiler and the English Mastiff.

The history And Overview of the English Mastiff

The English Mastiff is one of the oldest breeds of dogs, with a history that dates back thousands of years. The English Mastiff is a large and ancient breed of dog. Originating in the British Isles, the Mastiff was used for hunting large game such as boar and deer.

The ancient Romans used them as guard dogs, and they were also popular among the British nobility. Today, they are still prized for their size, strength, and loyalty. English Mastiffs typically weigh between 150 and 230 pounds and stand 27 to 32 inches tall at the shoulder.

They are massive dogs with large heads and thick necks. Their coats are short and dense and come in a variety of colors, including brindle, fawn, and black.

English Mastiffs are gentle giants known for being calm and loving with their families. They are also extremely protective, making them excellent watchdogs.

While they can be aggressive toward strangers, they are not naturally aggressive dogs. With proper socialization from an early age, they can get along well with other animals and children.

If you are looking for a devoted companion with a surprising amount of personality, the English Mastiff may be the perfect breed for you.

The English Mastiff’s lifespan is between 6 to 10 years, and it was recognized as a breed by the American Kennel Club in 1885.

The history And Overview of the Rottweiler

The Rottweiler (Rottie) is a versatile breed that originated in Germany. They were originally bred as working dogs, and their powerfully built bodies and loyal nature made them well-suited for herding and guarding.

Today, they are still commonly used as working dogs, but they also make excellent companions. Rottweilers are intelligent, fearless, and obedient, and they have a strong protective instinct.

They need plenty of exercises, but they are also calm and relaxed indoors. They can be good with children and other pets with proper training and socialization.

Rottweilers are a popular breed, and they have been used in movies, TV shows, and books. They are genuinely versatile dogs that make great companions for active families.

Rottweilers typically weigh between 80 and 135 pounds, and they stand 22 to 27 inches tall at the shoulder. They have a short, thick coat that is black with rust-colored markings.

The Rottweiler’s lifespan is between 8 and 10 years, and they were recognized as a breed by the American Kennel Club in 1931.

The Appearance Of The Rottweiler Mastiff Mix

Generally, the appearance of Mastweiler is a dog with a strong build and a muscular body. 

The head is large and square, with a short muzzle and floppy ears. The eyes are dark and expressive, and the teeth are strong and well-defined.

However, nothing is guaranteed in the appearance of puppies in the same litter, as each puppy can inherit more genes from one parent over the others.

If your puppy inherits more genes from the Rottweiler parent, the head will likely be triangular but blocky with pendant-shaped ears that are medium in size. 

However, if your pup inherits more English Mastiff genes, the head will be large and square with a short muzzle, and floppy ears with extra skin fold around the neck.

In all, expect your dog to be a combination of both parents in terms of appearance.

The Size

The size of hybrid parents will contribute to the overall size of their offspring. Rottweilers are generally considered a large breed, and Mastiffs are an extra-large breed. 

As a result, most Mastiff Rottweiler mixes will fall into the large category. However, it is not uncommon for some of these dogs to be on the larger side, reaching heights from 24 inches all the way up to 27 inches or more at the shoulder.

While size can vary depending on the parent breeds involved, most Mastiff Rottweiler mixes will weigh between 100 and 180 pounds

This is definitely a dog that is not suited for small living spaces. If you are considering this hybrid, be prepared to provide plenty of room for your dog to move around. A large backyard or a rural property would be ideal.

The Coat Type And Color

We can determine these breeds’ coat type and color by looking at the parent breeds. Rottweilers have short double coats, and Mastiffs have a short double coat, straight outer coat with a dense, shorter undercoat. 

The Mastweiler will likely have a double coat inherited from the two parent breeds.

As for coat color, Rottweilers are either black with rust-colored markings or mahogany color. Mastiffs come in many colors, including brindle, fawn, and apricot. 

Therefore, a Mastweiler can come in any color combination of the two parent breeds. The most common colors are black and tan and black and mahogany.

Mastiff Rottie Mix Lifespan

A Mastiff Rottweiler mix’s life expectancy is around 7 to 12 years. However, some factors such as health conditions, diet, and exercise can affect their lifespan. 

How you take care of your dog will also play a significant role in how long they will live.

Mastweiler Temperament & Personality

The Temperament and personality of puppies in a litter can differ depending on individual dogs and their parents’ personalities.

The English Mastiff temperament is good-natured, affectionate, calm, courageous, dignified, and protective.

The Rottweiler temperament is steady, self-assured, devoted, good-natured, obedient, confident, fearless, and alert.

However, the most common trait of Mastweilers is that they are loyal and protective dogs who make great family pets. They are also intelligent and have a lot of energy. 

If you’re thinking about getting a Mastweiler, we will advise you to visit a reputable breeder to see the parents and meet some of the puppies. That way, you can ensure that you’re getting a healthy puppy with a good temperament.

Mastiff Rottweiler Mix Dietary Needs

This breed should do well in high-quality dog food formulated for large breeds. Mastiffs are known to be gluttonous, so it is best to portion meals accordingly and not free feed. This will help prevent bloat, a life-threatening condition that can affect deep-chested dogs.

Also, the diet should have an appropriate phosphorous/calcium ratio to help prevent skeletal disorders because of the Mastiff parents. 

If you are unsure what to feed your Mastweiler, speak with a veterinarian or canine nutritionist for specific dietary recommendations. 

In general, large breeds require more calories than small breeds. A good rule of thumb is to feed your Mastweiler about two to three percent of his body weight in calories per day.

Watch your dog’s calorie consumption because these breeds are prone to weight gain, which can lead to joint problems later in life. It is vital to maintain a healthy weight to prevent these issues.

Fresh and clean water should be available at all times. If your Mastweiler is active or working, he may require more water than a sedentary dog. Always have fresh water available and encourage your dog to drink after exercise.

Dietary supplements are not necessary for this breed unless recommended by a veterinarian. If you choose to supplement, do so under the guidance of a professional.

Their diets need to have a good amount of protein but shouldn’t be more than 26 percent, and you can supplement their food with fresh fruits and vegetables or as a treat during training sessions.

Grooming Requirements

These breeds are not difficult to groom. The short, hard coat of the Rottweiler is easy to care for, and the Mastiff’s long, thick coat only requires brushing once or twice a week.

Weekly brushing will help to reduce the amount of hair around your home. A toothed comb or a slicker brush is recommended to remove any mats or tangles and keep your dog’s skin shiny.

These dogs are moderate shedders and are not hypoallergenic dogs. So you may find hair on your clothing and furniture. A good vacuum cleaner with a pet hair attachment will help to remove the hair from your home.

These dogs only need to be bathed when they are dirty. Baths should only be given when necessary as over-bathing can strip the natural oils from the skin and coat.

Both breeds are prone to drooling, so be prepared to have a slobber cloth or two on hand. The Mastiff is also known to be a slobberer, so you may want to keep his face clean with a damp cloth or baby wipes.

As part of a good grooming routine, brush your dog’s teeth to prevent gum disease and tooth decay. Check his ears weekly for any redness, discharge, or bad smell, which could indicate an infection. And lastly, clip his nails monthly or as needed.

Your Mastiff and Rottweiler mix will be a healthy and happy dog with proper grooming. 

However, because of their weight and size when they become adults, we advise you to start early with the grooming regime so that your pup gets used to it from an early age. Trust us; it will make things a lot easier for both you and your dog in the long run.

Exercise Requirements

The Mastiff parents were bred to be guardians and require low exercise requirements. The Rottweiler parent was bred as a herding dog and required higher exercise requirements. 

To stay mentally and physically fit, a Mastiff Rottweiler mix will likely have moderate to high exercise requirements. They will need at least one good walk, hike, or run a day and may also enjoy some playtime in the yard.

However, exercise intensity will depend on the individual dog’s energy level. Some may be content with a few short walks, while others will need more vigorous exercise. It is important to find an activity that your dog enjoys and stick to a routine.

They will need indoor exercises or games as well, such as fetch or tug-of-war, to keep their minds active.

If you cannot provide enough exercise for your Mastiff Rottweiler mix, they may become bored and destructive. This can lead to problems such as chewing, digging, and excessive barking. A tired dog is a happy dog, so make sure to give them enough exercise to avoid behavioral issues.

The best way to determine how much exercise your Mastiff Rottweiler mix needs is to talk to your veterinarian. They will be able to give you specific recommendations based on your dog’s age, health, and energy level.

Training Your Mastweiler 

These are large dog breeds originally bred for guarding and protection, so it’s essential to start training your Mastweiler early as they can be challenging to handle if not adequately trained.

Both the Rottweiler and the Mastiff have a reputation for being aggressive, so it’s important to socialize your puppy and expose them to as many different people and animals as possible.

Basic obedience training is also a must, as Mastiffs are notoriously stubborn and headstrong. If you’re thinking about getting a Mastiff and Rottweiler mix, be prepared to put in the time and effort to train them properly. 

With the right training, your Mastiff Rottweiler mix can be a loyal and loving companion.

These breeds will do well with positive reinforcement methods such as clicker training, as they are food motivated. Avoid using negative reinforcement methods such as scolding or physical punishment, which could further aggression.

How Much Does A Rottweiler Mastiff Mix Puppy Cost & Where To Get It?

A Rottweiler and Mastiff mix puppy can range from $400 to $1000, depending on the breeder, availability, location, and the parents’ lineage/quality.

You can find Rottweiler Mastiff mix puppies for sale from local breeders or online from websites and rescues.

When looking for a Rottweiler Mastiff mix puppy, be sure to do your research and only purchase from a reputable breeder.

 Are Rottweiler Mastiff Mixes Good in apartments?

Rottweiler Mastiff Mixes are large and powerful dogs that require plenty of space to run and play, which may not make them the best fit for apartments.

Mastiff and Rottweiler Mixes are best suited for homes with yards where they can romp and explore. They do not do well in small spaces and may become destructive if left alone for too long. 

If you live in an apartment and are considering a Rottweiler and Mastiff Mix, be sure to speak with a veterinarian or professional dog trainer to see if this breed is right for you.

Mastweiler Health Problems

Generally, the Mastweiler breed is a healthy dog. However, there are a few health problems that they are prone to or can get from any of their parent breeds. 

These health problems include hip dysplasia, eye diseases, allergies, cancer, heart disease, and bloat.

Hip Dysplasia

Hip dysplasia is when the hip joint does not fit properly into the socket. This can cause a lot of pain and lameness.

Eye Problems

Eye diseases are fairly common in the Mastweiler breed. Some of these eye diseases include glaucoma, cataracts, and progressive retinal atrophy.


Allergies are also reasonably common in this breed. They can be allergic to pollen, grass, fleas, etc.


Cancer is a big concern for the Mastweiler breed. They are more prone to getting cancer than other breeds of dogs.

Heart Problems

Heart disease is also a concern for this breed. Some of the heart diseases they can get include cardiomyopathy, pulmonic stenosis, and subaortic stenosis.


Bloat is a condition where the stomach fills with gas and twists. This can be very painful and even fatal.

The best way to prevent these health problems is to get your Mastweiler from a reputable breeder who does health testing on their dogs.

Ask the breeder for health insurance clearance on the parents of your potential pup, as well as request to see any health certificates the breeder may have. This will ensure you’re bringing home a healthy dog.

You should also take your Mastweiler to the vet for regular checkups and screenings. You can catch any health problems early and get them treated before they become serious.
