While they may not be as big as their close cousins, the English Mastiff, the Bullmastiff is still a very large dog. On average, bullmastiffs weigh 100-130 pounds and reach 27 inches. However, while they might seem intimidating, this large breed is actually a gentle giant.

In the early 19th-century, gamekeepers bred Bullmastiffs to scare poachers that wandered onto their lands. Since then, bullmastiffs have worked alongside police officers, soldiers, and hunters. When they aren’t working, these watchdogs are probably curled up around your feet. They might weigh as much as their human companions, but that won’t stop a bullmastiff from trying to be a lap dog.

Bullmastiffs are easily recognizable, and not just because of their massive size. With broad shoulders, black markings and a droopy, wrinkly face, you can spot a bullmastiff from a mile away. Since they have an average life span of 8 to 10 years, a high-quality diet with natural ingredients is crucial to maintaining a bullmastiff’s health.

Here’s what you’ll learn in this article:

  • The Best Dog Foods for Bullmastiffs : We break down the healthiest choices by budget, diet, and popularity.
  • What Makes a Great Bullmastiff Dog Food : We analyze good and bad ingredients and inform you about breed-specific heath considerations.
  • FAQs : We answer feeding, nutrition, and growth questions commonly asked by Bullmastiff owners.

Understanding the Diet Requirements of a Bullmastiff

Bullmastiffs need a wholesome, high-quality diet. They do need plenty of protein, but not as much as you might expect. This breed may be large, but they aren’t always active. Many bullmastiffs would rather snooze on your lap than play fetch.

Generally, bullmastiffs require diets rich in meaty proteins, leafy vegetables, fruits, and essential vitamins. Vitamin C and minerals like calcium and zinc are especially important for the overall health of a bullmastiff.

On average, this breed needs to consume around 1,770 to 2,100 calories a day, depending on their activity level. In some cases, a highly-active bullmastiff may require up to 3,000 calories a day.

It’s best to avoid bullmastiff food containing artificial preservatives or flavoring—while these additives might make the formula taste “better”, they aren’t great for a bullmastiff’s health.

Another common issue within this breed’s diet are food irritants. Some Bullmastiffs may have issues digesting gluten or grain products and may function better on a grain-free diet.

Puppy Bullmastiff Diet – Bullmastiffs grow and develop at a slower pace than many other breeds. It’s important that bullmastiff puppies consume a large-breed puppy formula that will provide them with close to 22% protein as well as higher levels of essential vitamins and minerals.

Adult Bullmastiff Diet – Many Bullmastiffs don’t reach maturity until they’re 18 months to 24 months old. In some cases, it might take them 3 years to completely finish growing. However, once your dog is fully grown, it’s time to switch them to an adult large-breed formula. Many bullmastiffs consume around 25% protein in their diets as well as plenty of fruits and veggies.

Senior Bullmastiff Diet – With a shorter life span, bullmastiffs may begin to show signs of aging around 6 to 7 years of age. At this point, it’s best to begin gradually switching to a senior formula. Many aging bullmastiffs become less active in their golden years and may only require around 18% protein.

Along with providing your bullmastiff with wholesome, high-quality food, it may be beneficial to add a supplement like glucosamine to their diet. As they grow and develop, it’s crucial that this breed maintains muscle, joint, and skin health so that they can avoid problems later on.

Special Diet Considerations For Bullmastiffs

While the bullmastiff breed is typically healthy, they are prone to a few troubling health problems. While a healthy diet can’t completely prevent these issues, providing your dog with proper nutrition can lower the risk of some diseases or conditions. Here are some of the common ailments that Bullmastiffs suffer from:

  • Hip dysplasia
  • Allergies
  • Elbow dysplasia
  • Hypothyroidism
  • Cancer
  • Bloat
  • Obesity

Hip dysplasia and elbow dysplasia are common problems in medium and large-breeds. Dysplasia occurs when the hip or elbow joints form abnormally. While this can happen at any point during a Bullmastiff’s life, it’s usually more noticeable as they age.

Hip and elbow dysplasia can cause your dog to have a loss of function in the affected joints. They may have trouble rising, walking up stairs and running. Without treatment, some dogs may eventually lose the ability to walk.

Allergies are an issue in all breeds, but they can be a particular problem for Bullmastiffs. It’s not unusual for a Bullmastiff to have an allergy to gluten products, or issues digesting corn, soy, and wheat. Although allergic reactions might vary from dog to dog, common symptoms include itching, diarrhea, and chronic ear infections.

Bullmastiffs are also prone to Bloat, or gastric dilation. This life-threatening condition occurs when the stomach distends with swallowed air and causes an obstruction in the stomach. If it’s severe enough, the distension may interrupt blood flow and cause tissue death.

While the cause of this condition is unknown, some experts believe that excessive exercise immediately after eating may contribute to it. It’s crucial to catch gastric dilation early—warning signs include bloating, dry-heaving, weakness and staggering.

While many of these Bullmastiff health issues aren’t preventable, obesity is. Since this breed tends to be less active, it’s easier for them to gain weight. Obesity can lead to other health concerns like joint or cardiac problems. The best way to counteract the risk of obesity is by following a feeding schedule and encouraging your dog to be more active.

Bullmastiff Feeding Chart

Speaking of feeding schedules, it’s essential to keep your Bullmastiff on a food regimen. Free feeding is not an ideal option—many dogs may overeat and gain weight or spend all day picking at their food.

Bullmastiff puppies should generally eat 3 times a day. The amount of food will vary depending on the specific brand’s feeding instructions, and your dog’s weight and age.

As they become adults, bullmastiffs can still eat 3 times a day, but many owners choose to feed them twice a day. Regardless of what you choose, these meals should be spread out—like breakfast, lunch, and dinner. Spreading out the meals will ensure your Bullmastiff is not eating too much at once.

It’s a good idea to stick to the same feeding routine so that your dog’s digestive system can adjust.

Bullmastiff FAQ : Feeding Questions Answered

While knowing more about the best bullmastiff food out there is helpful, it might not answer every question you have about your dog’s nutritional requirements. Fortunately, you don’t need to wonder any longer—here are some of the most common questions Bullmastiff owners want the answers to:

Q: How much food should I be feeding my Bullmastiff?

A: Since most Bullmastiff food doesn’t come premeasured; you might not be sure how much you need to feeding your furry friend. The good news is that you don’t need to guess. Any brand you buy will also come with feeding instructions, and some Bullmastiff food may even include its own measuring cup.

Since every dog is different, the amount of food might vary based on your dog’s activity level and weight. If you follow these directions closely, you shouldn’t need to worry about overfeeding or underfeeding your dog.

However, if you do notice that your pup is losing or gaining too much weight, it might be time to reassess the quantity of Bullmastiff food they’re getting.

Q: What type of food do Bullmastiffs eat?

A: The biggest issues you’ll face when feeding your Bullmastiff food are allergies and sensitive stomachs. While any Bullmastiff should be eating a natural, high-quality diet, not all of them will react positively to the same ingredients. The most common irritants for Bullmastiffs tend to be grain products and certain protein sources like chicken and poultry.

Generally, most Bullmastiffs do enjoy freeze-dried raw meat or high-quality kibbles. It’s always best to combine a real meat protein source with a variety of vitamin-packed fruits and veggies.

Q: How do I know my Bullmastiff has a food allergy?

A: Allergies can pop up in a variety of forms, and it can be difficult to know whether or not your Bullmastiff is allergic to their food or another part of their environment. If you begin to notice gastrointestinal problems, chronic ear infections or diarrhea, it’s a likely sign that your Bullmastiff is suffering from a food allergy.

However, before you begin switching out their food, it’s best to talk to your vet so that you can be sure their symptoms aren’t related to another health issue. Once you know what ingredient is causing the issue, you can work on finding Bullmastiff food that doesn’t contain it.

Q: What types of fruits vegetables should a Bullmastiff be eating?

A: While many fruits and veggies are beneficial, some may be more important than others. These include:

  • Pumpkin
  • Sweet potatoes
  • Spinach
  • Orange
  • Cabbage

Fruits like pumpkin can help aid in the flow of digestion, and leafy green veggies usually contain plenty of antioxidants and essential vitamins.

Q: Should I feed my Bullmastiff supplements?

A: In many cases, Bullmastiffs, especially those that suffer from health issues, can benefit from the added nutrients of a supplement. It’s not uncommon for Bullmastiffs to take glucosamine or calcium supplements.

That being said, it’s important to speak with a veterinarian about your Bullmastiff’s specific dietary needs before you add a supplement to their diet. Your furry friend might already be eating enough of the substance and might not need a supplement.

Unless a veterinarian recommends it for your dog, you don’t want to add a Vitamin C supplement to their diet—too much of this vitamin can cause serious issues in a Bullmastiff.

Q: How many times a day should I feed a Bullmastiff?

A: Some Bullmastiff food might include directions about feeding times, but it’s generally a good idea to split your dog’s daily food intake into two or three meals a day. Spreading out feeding times is also important to make sure your Bullmastiff doesn’t end up overeating or picking at their food throughout the day.

Many owners follow a breakfast, lunch and dinner feeding regimen. Not only does this sufficiently spread meals out, but it allows a Bullmastiff’s digestive system to adjust to a regular schedule.

It’s important to make sure that, whenever you feed them, your Bullmastiff doesn’t immediately exercise afterward. Excessive exercise directly after a meal can contribute to gastric dilation, a serious health condition.

Q: Do Bullmastiffs need to follow a grain-free diet?

A: There’s a lot of controversy surrounding the use of grain-free diets in Bullmastiffs. While grain-free diets help reduce the possibility of allergic reactions or digestive issues, they aren’t a requirement. However, many Bullmastiffs do have problems with grain products like corn, soy and wheat, and many benefits from following a grain-free diet.

If you find that your Bullmastiff has issues with grain products or is just a picky eater, it might be time to gradually switch them to a grain-free recipe.
