What Is a German Shepherd Mastiff Mix?

The German Shepherd Mastiff mix is a cross between a purebred GSD and a Mastiff dog. It is also known as the Mastiff Shepherd, GSD Mastiff mix, Mastiff German Shepherd, or German Mastiff. Despite its tough facade, this hybrid is loyal, friendly, and gentle.

Carrying its German Shepherd and Mastiff parent genes, the German Shepherd Mastiff mix is one of the largest dogs in the canine kingdom. That said, this pooch is undoubtedly a head-turner!

For starters, the German Mastiff hybrid is born by crossing German Shepherd breeds with any Mastiff breeds. 

This means mixing any variant of a purebred German Shepherd, such as the liver GSD, black GSD, blue GSD, DDR German Shepherd, and others, with a Mastiff dog breed.

These breeds include the Tibetan Mastiff, English Mastiff, Neapolitan Mastiff, Bullmastiff, and Spanish Mastiff, just to name a few. 

Interestingly, a Mastiff German Shepherd mix born from a GSD English Mastiff cross has its own name — the English Mastiff Shepherd. This is probably due to their popularity among other combinations.

However, an unfortunate fact about this mix is that it cannot be registered with national kennel clubs. As a result, there is no existing standard for the Mastiff Shepherd mix.

German Shepherd Mastiff Mix Origin and History: Where Does the Mastiff Shepherd Come From?

As a relatively new hybrid, there is no extensive information available on the origin of the German Shepherd Mastiff mix. Fortunately, we know a lot about its parents. Let’s learn a bit about the history of its parents.

For starters, the German Shepherd originated in the late 1800s in Germany. These dogs were primarily used for herding sheep. 

The breed became prominent after World War I when soldiers used them for their trainability and athleticism. Needless to say, soldiers admired German Shepherd dogs, and they played a big role in the war.

As for the Mastiff, this breed has been around since 650 B.C. The Mastiff worked as a farm dog and watchdog for livestock. This breed was also property protectors and herding dogs back then.

Despite the German Shepherd and Mastiff’s rugged background, these breeds were later adopted as family companions. Both Mastiff dogs and GSDs are known for their gentle, loving, and loyal temperaments.

Luckily, the German Mastiff inherited the best traits from its parent breeds. This hybrid dog is steadily gaining popularity among pet enthusiasts looking for a sizeable yet gentle home buddy. 

Hopefully, as more people take an interest in German Mastiffs, we’ll get to know more about their history!

German Shepherd Mastiff Mix Appearance: What Does a Mastiff Shepherd Look Like?

It is pretty common for mixed breeds, like Mastiff Shepherds, to not have a standard look. After all, GSDs and Mastiffs do not have a lot in common, except for their short coats and abilities as guard dogs. 

Nevertheless, there are still some common features that are present among most Mastiff German Shepherd mixes.

A German Shepherd Mastiff mix is a huge dog with a massive head and a broad muzzle. Its ears are often perked up and slightly larger than a Mastiff’s. However, they can also sport folded ears from time to time. 

The face of this mixed breed has many black areas, particularly on the nose. Meanwhile, its body sports an obvious robust stature. 

Additionally, the proportion of this mixed breed is rectangular. This means they are longer than they are tall.

In terms of gait, the German Mastiffs adopt the confident stance of the German Shepherd and Mastiff breeds. This makes them intimidating to look at at first glance.

In terms of coat quality, the coat on this mix is dense and short. They also have a soft undercoat. Like its Mastiff and German Shepherd parent, this hybrid also sheds.

The Mastiff Shepherd’s coat colors include black, fawn, tan, and brindle. As expected, these dogs can sport either Mastiff or German Shepherd colors.

German Shepherd Mastiff Mix Size and Weight: How Big Do Mastiff Shepherds Get?

When it comes to size and weight, a female Mastiff Shepherd is around 22 to 24 inches tall and weighs between 130 and 160 pounds. 

Meanwhile, a male Mastiff Shepherd grows to a height and weight of 27 to 30 inches and 160 to 190 pounds, respectively.

Usually, the size and weight of designer dogs lie in between the size of their parents. As you can expect, this is also the case for large breed dogs, such as the Mastiff Shepherd.

With the measurements above, it is clear that Shepherd Mastiff mixes will grow up to be big dogs like their parents. However, you should remember that there are different factors affecting the size of your pooch. 

One of the most significant factors is the breed of its Mastiff parent. If you want to learn a little bit more about this, read our article on the Mastiff size and growth

German Shepherd Mastiff Mix Temperament: Do Mastiff Shepherds Make Good Family Dogs?

Usually, giant breeds are often regarded as aggressive dogs. Sadly, this is true to some extent. 

The aggressive tendencies of the Mastiff Shepherd are rooted in the protective nature of its parents as good guard dogs. Don’t worry, though, as this behavior can be managed through early socialization training.

While they have a tendency to be violent, Mastiff Shepherds are generally calm and lovable dogs if they are raised properly. The only time these dogs retain their aggressions is when they have a history of abuse.

In general, the Shepherd Mastiff cross has a pleasant personality that pet enthusiasts adore. This dog is devoted to its family and will do everything in its power to protect its favorite bunch.

In addition, the Mastiff Shepherd is docile and tender. It can be left alone with children and even other animals. In fact, this pooch is a master of bite inhibition, which allows it to hold tiny creatures between its jaws gently.

When it comes to training, this mix does not fall behind. It takes after its parents’ intelligence. Hence, teaching the Mastiff Shepherd tricks and commands is pretty easy.

All things considered, you should still take the necessary precautions when owning a large dog. This includes supervising them when socializing with strangers, putting on a strong leash during walks, and the like.

German Shepherd Mastiff Mix Lifespan and Health Issues: Are Mastiff Shepherds Healthy Dogs?

German Shepherd Mastiffs live between 8 and 12 years. Thanks to their healthy parents, their lifespan is slightly longer than most giant breeds. In fact, some German Shepherd Mastiff mixes can live for 15 years!

Mixed breeds like the Mastiff Shepherd benefit from the concept known as hybrid vigor. This is the scientific term describing the unique potency and improved immunity of crossbreeds. 

However, despite its good health, the German Mastiff is still at risk of a handful of health issues. The most common ones they encounter are those associated with their giant stature.

Below are some of the common health problems of a German Shepherd Mastiff mix:

  • Hip and Elbow Dysplasia: Canine hip and elbow dysplasia is a common health issue among giant dogs like the Mastiff Shepherd. Due to their size, their joints and muscles deteriorate faster. One way to prevent hip and elbow dysplasia is by making sure your dog is within its ideal weight.
  • Bloat: Large dogs are prone to bloating. This condition is characterized by the sudden build-up of pressure in a dog’s stomach. This health issue is known to affect Mastiff Shepherds. Bloating requires immediate medical intervention as this health emergency can cause sudden death.
  • Cushing’s Disease: Cushing’s disease occurs when there is excess cortisol in a dog’s body. This may lead to a wide range of health issues for your Mastiff Shepherd mix. Cushing’s disease usually results in kidney damage, diabetes, or even death.
  • Progressive Retinal Atrophy (PRA): Progressive retinal atrophy is a group of degenerative diseases targeting a dog’s eyesight. This might cause permanent vision loss to your German Mastiff if left untreated. Sadly, the German Mastiff may inherit PRA from the GSD and Mastiff breeds.

The list provided above is by no means complete. The German Mastiff is prone to other health problems, including allergies, cataracts, and seizures. To fight off these diseases, always keep your Mastiff Shepherd in tip-top condition.

How to Take Care of Your German Shepherd Mastiff Mix

Believe it or not, the Mastiff German Shepherd mix is not a high-maintenance dog. However, there are a few things you should know when looking after this giant pooch. 

In this section, you’ll find some useful tips for taking care of your German Shepherd Mastiff mix. We will specifically touch on three key areas, namely, nutrition, grooming, and exercise.

Food and Diet

The right food for your German Mastiff is not determined by the brand but rather the nutritional elements it contains. In general, it’s recommended to try out a few dog food brands for your pooch. 

A healthy, balanced diet for the Mastiff Shepherd should be packed with proteins, fats, minerals, and carbohydrates.

In terms of feeding quantity and frequency, the German Mastiff should be fed with three meals of nutritious kibble per day: one in the morning, another during lunch, and the last one in the evening.

If you want to try an alternative to commercial dog food, try giving it a raw diet. This has a handful of health benefits for German Mastiffs.

Cleaning and Grooming

Luckily for you, the short and stiff coat of a Mastiff Shepherd does not require a special grooming routine; daily brushing should be enough to keep your pooch’s coat soft and shiny.

German Mastiffs also don’t need to be washed frequently. In fact, these dogs will be perfectly fine even if you bathe them just once every two months. This practice is even beneficial for retaining healthy oils on their skin and fur.

However, the exception is when your dog gets visibly dirty or stinky. In this case, it’s time for them to hop into the shower for a good scrub. 

This is probably the only time grooming becomes tedious as Mastiff Shepherds are large dogs. If you want, you can always opt to take them to the groomers instead. 

In addition to maintaining your Mastiff Shepherd’s coat, you should also clean its teeth, ears, and eyes. Tartar build-up and ear and eye infections are some of the things you should watch out for.

Training and Exercise

Generally, the German Shepherd Mastiff mix is not an extremely active dog. Unlike its GSD parent, this hybrid does not require much physical stimulation. 

Taking your Mastiff Shepherd for a 30- to 45-minute walk each day is enough for it to stay happy and healthy. It will also benefit from some bursts of energy throughout the day, so playing fetch is a nice additional workout. 

In terms of training, the Mastiff Shepherd responds pretty well, thanks to its wits. The best approach when training your German Mastiff is through using praises and rewards. 

If you’re having trouble with your dog’s temperament, we recommend consulting a professional dog trainer.
