What Is a Bullmastiff German Shepherd Mix?
The Bullmastiff German Shepherd mix is a cross between two popular canines — the protective and loyal Bullmastiff and the intelligent and active German Shepherd. This hybrid dog is great for most pet owners, even families with young children. This dog is affectionate as much as they are protective.
Both of its parents are large breeds, so it’s no surprise that the Bullmastiff German Shepherd mix is just as big. Although, its appearance varies and has physical features from either of the parents.
This mix, sometimes also called the German Bullmastiff, is a designer hybrid that is very rare among dog owners. This could be the reason why they are not yet recognized by the American Canine Hybrid Club (ACHC).
Bullmastiff German Shepherd Mix Origin and History
It is uncertain when the Bullmastiff German Shepherd mix was first produced. Nevertheless, you can take a look at the history of its parents to know more about this mix.
The first German Shepherd is named Horand von Grafrath. It was developed by a German cavalry officer, Von Stephanitz, for military use in 1899. To this day, the German Shepherd is popular for being a police dog.
Aside from being a service and war dog, Horand also served extensively as a stud, and it is believed that his genes are present in every German Shepherd today.
On the other hand, developed in 1860, the Bullmastiff is a cross between the English Bulldog and the English Mastiff.
They were bred to serve as estate guard dogs and proved to be fast and ferocious in tracking thieves.
Due to their parent breeds’ origins, the Bullmastiff German Shepherd mix proves to have a dependable nature and protective instincts.
Bullmastiff German Shepherd Mix Appearance
The Bullmastiff German Shepherd has an unpredictable appearance. Its physical features may either strongly resemble one of its parents or a good mix of both.
In terms of body type, they either have a muscular and large body like their Bullmastiff parent or a slender, lean, and athletic body like the German Shepherd.
In terms of their face, they can have large heads and differently-sized muzzles. These can be short, long, or average and are typically black. For this breed, their eyes are commonly brown.
The texture and color of their coat also vary. If they inherit the smooth and short Bullmastiff coat, they will likely have fawn or red fur that is either brindle or solid-colored.
Bullmastiff German Shepherd Mix Size and Weight
Based on the size and weight of their Basset Hound and GSD parents, an adult Bullmastiff Shepherd mix stands around 23 to 27 inches tall and weighs 80 to 120 pounds.
They reach their full-grown size when they are around 18 to 20 months, similar to their parents.
However, overweight and obese German Bullmastiffs may reach up to 200 pounds, so it’s crucial to control their food intake.
Bullmastiff German Shepherd Mix Temperament and Personality
While each dog is unique, practically all Bullmastiff German Shepherd crossbreeds share a few personality features. In general, the German Bullmastiff is a stubborn gentle giant.
Despite coming from a powerful; lineage, German Bullmastiffs are calm and well-behaved due to the laid-back personality of the Mastiff and the loyalty of the German Shepherd parent.
Families with children will have no problem having this dog around. They won’t display aggressive behavior unless provoked.
As early as possible, German Bullmastiff owners are encouraged to socialize their pets. This is to ensure that the kind and gentle side of their personality becomes dominant.
Bullmastiff German Shepherd Mix Lifespan and Health Issues
Hybrids are generally healthier than purebreds, but their exact lifespan can be quite difficult to determine. Based on the average lifespan of its parents, the lifespan of the Bullmastiff Shepherd ranges between 8 and 13 years.
Although, like other large dogs, the Bullmastiff German Shepherd mix also experiences some health issues, such as the ones below:
- Osteochondrosis: This condition causes the development of immature cartilage among German Bullmastiffs when they grow very quickly, causing pain and inflammation. Osteochondrosis can be treated through surgery.
- Bloat: Bloat occurs when dogs like the Bullmastiff German Shepherd mix eat too fast, causing stomach enlargement. This condition may progress into a more concerning problem called gastric dilatation and volvulus (GDV).
- Obesity: In the United States, 56% of dogs are either overweight or obese. This becomes problematic for large breeds like Bullmastiff German Shepherd mixes that are predisposed to joint problems.
Thankfully, there are ways to avoid these issues. Proper feeding habits, a healthy diet, and regular exercise are the easiest way to maintain a healthy German Bullmastiff.
How to Take Care of Your German Shepherd Bullmastiff Mix
Having a unique dog breed entails meeting its equally unique needs. A proper diet, adequate physical activity, and a grooming routine are key to keeping your dog happy and healthy.
Here we highlighted the most important tips for taking care of your Bullmastiff Shepherd mix.
Food and Diet
In general, large breed Bullmastiff cross German Shepherd dogs must be fed a low-fat and high-protein diet. Their food must also be high in energy since they are energetic but just enough to avoid unnecessary weight gain.
In terms of their daily food quantity requirement, a puppy between 2 and 3 months may need 1 to 1.5 cups of food, while for adults, it could be 3 to 4 cups of food a day, similar to its German Shepherd parent.
Choosing the best dog food from the vast selection of options on store shelves can be challenging.
To ensure that your dog is eating high-quality food, look for products marked with the Association of American Feed Control Officials (AAFCO) seal of approval.
Cleaning and Grooming
In terms of grooming, their needs vary depending on their coat and daily activities. So, the best hygiene routine for your German Bullmastiff is the one that is specific to its needs.
For short and medium-coated Bullmastiff Shepherds, brushing every 3 to 7 days avoids matting and reduces shedding, which is typical for Shepherd hybrids. A monthly bath is also sufficient to keep them clean.
For long-coated Bullmastiff Shepherds, they need daily brushing. Perhaps, you also need to visit the dog salon at least thrice a year to remove their undercoat, depending on how fast it grows.
Other dog care routines, such as nail trimming and ear cleaning, should not exceed once every two months, while their teeth need to be brushed three times a week.
Training and Exercise
It’s always a good idea to train your German Bullmastiff puppy while they are clever and still responsive to your commands. Once they grow older, they can be really stubborn.
While training, expose your dog to sensations like noise, smell, and touch. Also, introduce them to other animals and young children. This trains the territorial German Bullmastiff to be gentle and not see them as threats.
For large German Shepherd mixes, a 60-minute exercise is needed daily to reduce their pent-up energy.
Some activities you can enjoy together include running, walking, or playing fetch at the dog park. When they get older and start suffering from joint pain, exercise is actually a great way to prevent some discomfort.

That said, here are the benefits of having a German Bullmastiff:
- Great for any pet owner: The only intimidating quality of this hybrid is its size. These gentle giants are loving creatures and provide warmth and comfort to any family, even those with children.

- Rare hybrid: Having a unique and rare hybrid can be quite interesting. It can be advantageous to pet owners so they don’t miss their pet in a crowd of dogs playing at the park.
These qualities are some of the reasons why the German Bullmastiff makes great companions. As with any other breed, they also have characteristics that are incompatible with some dog owners.
Here are some of the cons of having a German Bullmastiff:
- Requires an active lifestyle: Since large canines can quickly gain weight and are prone to joint problems, they need regular exercise to maintain a healthy body. If you are a busy parent, your Bullmastiff Shepherd will miss a lot of fun times walking and running in the park.
- Not hypoallergenic: Although they shed moderate amounts of fur, they are still not hypoallergenic. Therefore, a German Shepherd Bullmastiff is not recommended for people with pet allergies.
- Not recognized by the AKC or ACHC: Having a dog that is registered in the AKC or ACHC lets you know the accurate ancestry of your dog. Since they are not recognized by any major clubs, you won’t have official documents to know the pedigree of your German Shepherd Bullmastiff mix.
As you can see, the disadvantages of owning a Bullmastiff Shepherd mix are not rooted in their personalities. This is because nothing bad can be said about their warm characters.
