Bullmastiffs, with their imposing presence and gentle nature, are wonderful family guardians. These powerful dogs have specific nutritional needs to support their large frame and health. At Petabolix, our experts have curated top food recommendations to ensure your Bullmastiff thrives at every life stage.

Breed Summary

The Bullmastiff is a formidable yet affectionate breed known for its loyal and protective nature. Developed in England in the 19th century, Bullmastiffs were bred by gamekeepers to guard estates against poachers, combining the strength of the Mastiff with the agility of the Bulldog. These large dogs typically weigh between 100-130 pounds and possess a muscular, solid build.

Bullmastiffs are known for their gentle and calm demeanor, making them excellent family pets and loyal protectors. Despite their size, they are relatively low-energy indoors but require regular exercise to maintain a healthy weight and prevent boredom. Their short, dense coat is easy to maintain, but their large size means they have significant dietary needs to support their overall health.

These gentle giants are well-suited to households with ample space and benefit from a consistent training regimen to manage their protective instincts. Understanding the unique characteristics and needs of Bullmastiffs helps ensure they receive the best care and nutrition.

Vet’s Note

Bullmastiffs are prone to certain health issues, including hip and elbow dysplasia, bloat, and heart conditions. Regular veterinary check-ups, a balanced diet rich in joint-supporting nutrients, and portion control to prevent overeating are crucial. Monitoring their weight and providing a diet tailored to support their large frame and potential health concerns will help keep your Bullmastiff in optimal condition.

Health Considerations for Bullmastiffs

Dental

A Bullmastiff's teeth and gums are always under plaque attack, which forms naturally from food particles and other bacteria. Dogs aren’t too concerned about having pretty white teeth, but dental care is critical for oral health. Bacteria in the mouth can even affect internal organs, like the heart, liver and kidneys, so there are certain things below we like to see in food or supplements to combat these threats to Bullmastiffs. Learn more about how to take care of your dog's teeth.

Sodium hexametaphosphate
Treats based on solubility, not hardness

Gut

Think of your Bullmastiff's gut like a diverse community of bacteria and other microbes that work together to keep the body healthy. Keeping all these balanced is very important for overall health, including digestive, mental, and immune well-being. For these reasons, we prefer Bullmastiff food that support the GI system and supplements that contain attributes below.

Bone & Joint

It’s very common for breeds like the Bullmastiff to develop discomfort or pain in their joints and bones, especially as they age. Some of these issues are hereditary, and some come from wear and tear over time. We can’t usually prevent these problems, but proper nutrition and weight management will do wonders in minimizing pain in our beloved pets. We always make sure diets include the ingredients below.

Cognitive

Puppy and senior Bullmastiffs need a little extra brain power in their nutrition plans. In the early years, puppy brains are developing quickly and need a healthy flow of vitamins to help them grow strong. Once they hit senior years, brain function can deteriorate and we like to supplement their diets with nutrients that will keep them sharp. Learn more about cognitive nutrition for dogs.

Eye

The only thing better than looking into your Bullmastiff’s eyes is looking into your Bullmastiff’s healthy eyes. All dogs are susceptible to degenerative vision and eye function, but supplementing their diets with things like beta carotene, lutein, EPA, DHA, and other nutrients can help maintain quality vision.

Skin & Coat

Skin is a Bullmastiff’s largest organ, and it plays a huge role in protecting from the outside world. Just think — weather, allergies, stress, parasites — all these things are trying to get under your dog’s skin. A healthy outer layer is key to avoiding irritants that may irritate or infect. And pay close attention to their coat. Unhealthy looking (or smelling) fur can mean bigger problems. To keep Bullmastiff skin & coats healthy, we recommend that diets contain ingredients below.

Heart

Chances are, if you’re doing what’s right for your Bullmastiff’s heart, you’re doing what’s right for his or her health overall. Proper exercise, weight management, and nutrition are all key to a healthy ticker. Most heart issues in dogs are a result of normal wear and tear with age, so heart-focused diets with taurine and omega-3 fatty acids from fish oil could be the gift of a lifetime for your Bullmastiff.

Immune

There is a powerful little army inside your Bullmastiff (the immune system) that protects the body from bacteria, viruses, parasites, toxins and countless other microscopic predators. As pet parents, our job is to keep this army strong, conditioned, and well-supplied. Most of the battle is won in the gut, so a balanced diet plus probiotics and antioxidants are key for victory.

Weight Management & Obesity

There is nothing more important than keeping your Bullmastiff at a healthy weight. Even a little excess poundage can cause a wide variety of health problems, including the pain of extra burden on their joints. Unfortunately, almost half of dogs in the US are overweight. Let’s fight dog obesity together by giving our dogs appropriate exercise and managing their caloric intake. If your Bullmastiff needs to shed a little weight, look for diets with these labels below.

Are Fresh Food Diets Good for Bullmastiffs?

Only if they’re properly balanced.

Many well-intentioned Bullmastiff parents spend a lot of time preparing meals at home, but health benefits are lost if meals aren’t properly portioned and balanced with all the nutrients dogs need. Recently, a few companies have done an excellent job ensuring accurate portions and nutrient balance by delivering pre-prepped fresh meals customized to the size and needs of your dog. Farmer’s Dog, Ollie and Nom Nom have each been approved by our nutrition team as delivering truly quality and well-balanced meals. They can be a little expensive (usually 3-4x more per day than kibble), but many find the added health benefits worth the cost. They do offer discounts to new customers, though, if you’d like to try one out.

Pros and Cons of Fresh Food Diets

✓ Diets balanced by Nutritionists
✓ Customized portions for weight control
✓ Superior digestive and immune health

Foods We Recommend for Bullmastiff Puppies

How long do Bullmastiffs need puppy food?
Until they're up to 24 months old

Bullmastiffs are very focused on growing, and how we feed them should help them do just that. Since they have so much growing to do, they need higher amounts of nutrients than adult dogs, especially proteins, fats, carbohydrates, vitamins, minerals and — don’t forget — water. It’s still important to not overfeed puppies, so make sure to portion food and keep treats to no more than 10% of their caloric intake. Since balance is so important, we recommend that your young Bullmastiff is eating food that is made just for puppies from a reputable brand.

Foods We Recommend for Bullmastiff Adults

When should Bullmastiffs start transitioning to adult food?
Until they're up to 24 months old

From a nutrition standpoint, Bullmastiff become adults once they reach about 90% of their expected weight. Once adults, our two key nutrition goals are balance and maintenance. We want balance because a dog’s body is responsible for a lot of things, like digestion, fighting infection, keeping muscles strong, and chasing squirrels. These are all important tasks, so we want to make sure each body function gets its share of nutrients. We also need to maintain a healthy weight. Underfed dogs are at risk for malnourishment, and overfed dogs can become obese — both of which lead to even worse problems for a Bullmastiff.

Foods We Recommend for Bullmastiff Seniors

When should Bullmastiffs start transitioning to senior food?
All dogs can age differently, but Giant dogs like the Bullmastiff can start to benefit from senior food around 5 to 6 years old

Ever watch kids running around the playground and wish you had that energy again? Yeah. Dogs get there, too. The metabolic processes in senior Bullmastiffs slow down as they age, which often means they aren’t needing quite as many calories as they did in their prime. Smart dog food companies have formulated senior diets to ease up on calories but still help them feel full and give them adequate maintenance protein. Still, like humans, everybody is different. Sometimes older dogs need just as many calories, or more, depending on how their bodies progress. So keep a close eye on their body condition, and look for dog foods made for seniors.
