Buyer's Guide: Choosing the Best Bullmastiff Dog Food

We all wish that selecting food for our pets was as simple as checking a few boxes based on their size and age. However, it’s much more complex and virtually tailored to each individual pup. Instead of focusing on a single cuisine or brand, use our buyer’s guide to create a list of potential options. Ensure that the solutions meet all their requirements before determining their preferences.

Buyers Guide Choosing the Best Bullmastiff Dog Food 1

1. Age

Even if you find a formula that advertises itself as suitable for a large or giant breed dog, you must also confirm the appropriate age. These dogs are often muscular and fluffy, requiring a large amount of resources to keep their bodies functioning properly.

As dogs age, they require a diverse mix of vitamins and minerals. They need fewer lipids and carbs because their bodies cannot utilize them efficiently.

Feeding mature dogs the same food they’ve always eaten almost certainly leads to weight issues, which are especially problematic for mature dogs because they put additional strain on their joints.

2. Grain vs. Grain-free

There are options not only for size and age but also for the type of diet you want to feed your puppy. One option is grain-based carbs, while the other is grain-free carbohydrates. Some individuals choose to give them raw food, although this usually entails cooking most of it.

There are many grain and grain-free possibilities among typical dog mixes. Consider which is healthier for your dog, as each has its advantages and disadvantages.

Although grain-free diets were once believed to be healthier, current research has shown that grains like wheat are a better source of some essential elements. Others argue that grain-free alternatives are more beneficial to dogs.

3. Nutrition

Consider the following nutritional facts while searching for the best option for large breed dogs:

Protein Composition

All dogs on average require 1 gram of protein for every pound of ideal body weight. The term “ideal” is important since protein content does not vary whether a dog is hefty or underweight. Adult dogs typically require 18% protein in their diet, while puppies require around 22%.

Large breed puppies need approximately 30% protein. There are different qualities of protein that dogs can process effectively, and paying a premium for food can provide better protein sources.


Carbohydrates are essential for dogs, just as they are for people. They are broken down into energy to keep them ready for anything life throws at them. Grains or grain-free substitutes are frequently important sources of carbohydrates in a dog’s diet. A combination of both is needed to maintain your pup’s energy levels.

Fat Content

The fat content required for different breeds varies. Large breed dogs may need slightly more fat than normal breeds, getting approximately 8% of their calories from fat. As with humans, some fats are healthier than others for dogs.

Calorie Intake

Calories are converted into energy immediately and can be found in almost every type of food. Larger animals have slower metabolisms, and giant dog breeds cannot process their food as quickly as other kinds. Too many calories can make them become hefty. For most dogs, aim for around 20 calories for every pound of ideal body weight each day, adjusting your calculations based on your veterinarian’s advice or at your own judgment.

Calcium to Phosphorus Ratio

Consider the ratio of calcium to phosphorus, which should be approximately 1.1:1 to 2:1 for hormonal balance.

Buyers Guide Choosing the Best Bullmastiff Dog Food

4. Mobility Assistance

A large breed dog, such as a Bullmastiff, often experiences joint problems, especially if they are hefty. They are already feeling increased strain in these vulnerable areas. Glucosamine and chondroitin sulfate are two important substances that alleviate this condition, acting like lubricants and keeping your dog robust. Providing enough of them can help your dog stay agile and prevent usual joint difficulties as they age.

5. Illnesses

Instead of just considering their breed and age, pay attention to the particular puppy. Do they have any medical conditions or allergies? Some dogs may not digest grain-free food effectively if they are allergic to any of the substitutes.

6. Price

Food prices are crucial since you have to buy it more frequently. While it is true that you get what you pay for, it is also true that brand name has a significant

influence on cost.

Some high-end companies raise their pricing because they employ higher-quality ingredients. However, if you are determined to provide the best for your dog, some study is required. Learn how a company obtains its food to determine if it is worth your money.

Some manufacturers can maintain excellent ingredients while keeping the price low. Feeding your dog properly does not have to be expensive.

If you’re interested in learning more about Bullmastiffs and their unique dietary needs, check out this informative article on the subject.


1. What is the nutritional needs of a Bullmastiff?

Bullmastiffs require a balanced diet to thrive. For puppies, a diet with 25-27% protein and 12-15% fat content from their daily calories is ideal. Adult mastiffs can thrive on 18-25% protein and 10% fat from their daily calories.

2. What foods are good for big dogs?

The ideal diet for big dogs includes lean protein from animal sources like meat, poultry, and fish, with low to moderate fat content based on their activity level.

Glucosamine and chondroitin are also recommended for joint health, with controlled levels of calcium and phosphorus. Additionally, larger kibble size can help control portions and reduce the dog’s risk of bloat.

3. Do mastiffs need special food?

Mastiffs need a food specifically formulated for large or giant breeds to stay healthy. Not feeding them the right type of food can put them at risk of health issues. Signs that your Mastiff’s food may not agree with them include excessive shedding.

4. Can bullmastiffs eat chicken?

Can bullmastiffs eat chicken? Yes, chicken is safe for bullmastiffs to eat as a treat or occasional food topper, as it is a common ingredient in commercial dog food and treats. However, it should be thoroughly cooked and unseasoned, and moderation is key when introducing new ingredients.

5. Are Mastiffs picky eaters?

Many mastiffs can be fussy eaters, but it’s understandable as who would want to eat the same meal every day? Rotating different freeze-dried meat toppers over their food can help keep things interesting and ensure they get the nutrients they need to stay healthy.
