The Origins of the Parent Breeds
To better understand the Bullmasstiff Shepherd dog, it’s helpful to take a look at the history and traits of its parent breeds.
The Bullmastiff originates from England where it was bred as an estate guardian in the 1800’s. Gamekeepers crossed Mastiffs with Bulldogs to create a powerfully built yet agile dog that could tackle poachers.
Despite their intimidating appearance, Bullmastiffs are calm, devoted, and loving. They form strong bonds with their family. Their size and protective instincts also make them natural guardians.
The German Shepherd
German Shepherds are one of the most popular dog breeds and for good reason. They are highly intelligent, energetic, and eager to please. With origins as herding dogs in Germany, German Shepherds take well to training and serve many working roles from police K9s to service dogs.
While very active and driven, German Shepherds are loyal pets that bond closely to their handler and family. Their watchful nature helps make them excellent guard dogs.
The Appearance of a Bullmastiff German Shepherd Mix
Since this is a cross between two pure breeds, the Bullmastiff Shepherd mix can vary greatly in physical appearance. They can resemble one parent more closely or be an even blend of both.
These dogs have a large, muscular build. They typically measure 23 to 27 inches at the shoulder and weigh 60 to 140 pounds when fully grown. Clearly, these are very big and powerful dogs!
The coat of the Bullmasstiff Shepherd is short to medium length and lies flat against the body. Common coat colors include:
- Black and tan
This hybrid may inherit the iconic black facial mask of the German Shepherd. They often have a broad head with drop ears, though some can have erect ears from the Shepherd lineage. Overall their appearance reflects their guarding breed origins.
Temperament & Personality of the Bullmastiff Shepherd
Since mixes can inherit a range of traits from their parents, their personalities are not as predictable as pure breeds. However, there are some common temperament characteristics found in Bullmastiff Shepherd hybrids:
- Loyal – Both parent breeds are known for their devotion. These dogs form tight bonds with their owners.
- Intelligent – With the German Shepherd’s influence, this cross is smart and trainable.
- Courageous – They are fearless when it comes to protecting their family and property.

Early socialization and obedience training will help ensure this hybrid grows into a well-rounded, stable temperament. With their extreme loyalty and intelligence, they thrive when given a job and purpose.
Activity levels can vary depending on which parent they take after. Bullmastiffs require moderate exercise while German Shepherds need more intense activity. Most Bullmasstiff Shepherds fall somewhere in between.
Exercise & Activity Needs
To stay fit and well-balanced, the Bullmastiff German Shepherd mix requires 60 to 90 minutes of exercise daily. This energetic crossbreed thrives when given daily vigorous activity.
As long as they receive adequate outdoor time and activity, these dogs will be calm and relaxed when indoors. However, without proper exercise they can become restless and destructive.
Here are some great ways to exercise your Bullmastiff Shepherd:
- Long walks – A long brisk walk each day will help meet their exercise needs.
- Playtime – Fetch, tug of war, and interactive toys provide physical and mental stimulation.
- Backyard play – Let them run around off-leash in a securely fenced area.
- Jogging or hiking – This breed can make a great jogging or hiking companion for active owners.
- Dog sports – Training in dog sports like agility, obedience, or nose work gives them an outlet for their energy and intelligence.
Because of their large size, activities like jumping and running on hard surfaces should be limited until they are fully grown around age 2. Otherwise, their joints are at risk of injury.
|Age||Exercise Time||Activity Type|
|2 – 6 months||20 – 30 minutes||Leash walking, indoor play|
|6 – 12 months||30 – 45 minutes||On-leash walking, backyard play|
|1 – 2 years||45 – 60 minutes||Moderate leash walks, supervised off-leash play|
|Adults||60+ minutes||Brisk walking, running, hiking|
As a general rule, puppies should have 5 minutes of exercise per month of age up to twice a day. Adult Bullmastiff Shepherds need a minimum of 60 minutes daily. Provide activities that engage their minds and bodies.
Training Tips for Bullmastiff Shepherd Puppies & Dogs
The Bullmastiff German Shepherd is an intelligent hybrid that is eager to work and please their owner. They are highly trainable when handled with patience, consistency, and positive reinforcement.
Here are some key training tips:
- Start young – Begin puppy obedience training as early as 8 weeks old. This helps socialize them.
- Use rewards – Food treats, praise, and toys motivate them to obey commands.
- Stay firm – Be consistent and don’t allow them to get away with disobeying known cues. This breed needs an assertive pack leader.
- Socialize often – Introduce them to new places, people, and animals frequently to prevent territorial behavior.
- Challenge their brains – Advanced training in agility, scent detection, or other “jobs” provides mental stimulation.
- Be patient – Don’t get frustrated. They are sensitive and will shut down if handled harshly. Positively reinforce desired behaviors.
Training should focus on basic obedience, leash manners, and socialization skills. Always use humane, reward-based methods. Harsh punishments will damage their trust.
Invest time into training, and this hybrid will become an incredibly well-behaved companion. For best results, owners should enroll them in puppy and obedience classes led by professional dog trainers.
The Bullmastiff German Shepherd mix has a short to medium length double coat that lies flat and close to the body.
Grooming requirements are relatively low maintenance:
- Brush regularly – Use a bristle brush and rub down their coat once or twice per week to remove loose hair. During shedding season daily brushing can help manage loose fur around your home.
- Bathe occasionally – Only bathe them every 2-3 months or as needed to avoid drying out their skin. Use a mild dog shampoo.
- Clean ears – Check and wipe their ears weekly to prevent infections.
- Clip nails – Trim their nails every 2-3 weeks to avoid cracking and overgrowth.
- Brush teeth – Daily tooth brushing promotes good dental health.
Shedding and drooling will be moderate. The Bullmastiff influence contributes to more drooling. Make sure to wipe down their facial folds regularly to prevent moisture buildup.
Nutrition & Feeding
These large hybrid dogs need specially formulated large breed dry dog food to support their growth and nutritional needs. Feed them a high-quality kibble and avoid cheap grains or fillers.
Follow your veterinarian’s recommendations for serving sizes. The amount fed should be divided into 2-3 meals throughout the day.
Here are some feeding guidelines based on your Bullmastiff Shepherd dog’s weight:
|Adult Weight||Daily Food (Split into Multiple Meals)|
|60 – 80 lbs||3 – 4 cups|
|80 – 100 lbs||4 – 5 cups|
|100 – 140 lbs||5 – 7 cups|
As a giant breed, care should be taken not to overfeed. Overweight puts excess strain on their joints. Limit people food, monitor their weight, and adjust food as needed to maintain a healthy body condition.
All giant breed dogs are predisposed to certain health conditions. Here are some to be aware of with the Bullmastiff German Shepherd mix:
- Hip dysplasia – Malformation of hip joints causing osteoarthritis. Weight management helps.
- Elbow dysplasia – Deformity of elbow joints also leading to arthritis.
- Bloat – Life-threatening twisting of stomach requiring emergency surgery. Don’t exercise for 1 hour after eating.
- Allergies – Environmental allergies are common. Symptoms include itchy skin, ear infections, and foot licking.
- Cancer – Both parent breeds have increased risk of certain cancers.
A responsible breeder will screen breeding dogs for dysplasia and eye issues. Purchasing from a breeder allows you access to health clearances.
Overall, with proper diet and exercise, the Bullmasstiff Shepherd enjoys relatively good health and can live between 9-14 years. Provide excellent preventative vet care to catch issues early.
