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
-
Bone & Joint
It’s very common for breeds like the Bullmastiffs 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.

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.

Are Fresh Food Diets Good for Bullmastiffs?
Only if they’re properly balanced.
Many well-intentioned Bullmastiffs 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.

Foods We Recommend for Bullmastiffs Puppies
How long do Bullmastiffss need puppy food?
Until they're 12 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 Bullmastiffs is eating food that is made just for puppies from a reputable brand.

Foods We Recommend for Bullmastiffs Adults
When should Bullmastiffs start transitioning to adult food?
When they're 12 to 24 months old
From a nutrition standpoint, Bullmastiffs 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 Bullmastiffs Seniors
When should Bullmastiffs start transitioning to senior food?
All dogs can age differently, but giant dogs like Bullmastiffs 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.
