Introduction to Feeding the Bullmastiff
Most dog owners do not know how to properly feed their dogs.
Also, most dog owners overfeed their dogs.
That explains why 59 percent of dogs and cats are overweight, according to research.
Overfeeding your Bullmastiff will make your Bullmastiff overweight and obese. Obesity leads to worse health problems for your Bullmastiff.
Unfortunately, the Bullmastiff is a dog breed that can become overweight very easily.
Therefore, you need to pay careful attention to what you feed your Bullmastiff and how much food you feed your Bullmastiff.
Furthermore, when you overfeed your Bullmastiff, you waste dog food. Wasting dog food is the same as wasting money. Dog food is a recurring expenditure that adds up to a lot of money over the lifespan of your Bullmastiff.
The average lifespan of the Bullmastiff is 7.46 years.
When you feed your Bullmastiff the right type of food and the right amount of food, your Bullmastiff will be of the right body weight and the right body condition (not overweight or underweight).
Similarly, underfeeding your Bullmastiff is as bad of a problem as overfeeding your Bullmastiff.
When you underfeed your Bullmastiff or feed your Bullmastiff an incomplete or unbalanced diet, you reduce your Bullmastiff`s quality of life.
The right amount of food that your Bullmastiff needs depends on six important factors.
You need to take all these factors into account when developing a meal plan for your Bullmastiff. These six factors are:- The life stage of your Bullmastiff (puppy, adult, or senior)
- The current weight of your Bullmastiff
- The body condition of your Bullmastiff (normal weight, overweight, underweight)
- How active your Bullmastiff is (inactive/obese prone, or active/athletic)
- If your Bullmastiff has been spayed/neutered
- The type of dog food that you feed your Bullmastiff
This article will provide you with a detailed guide on how to properly feed your Bullmastiff based on the above factors as recommended by veterinarians.
This article also includes the Bullmastiff food calculator that you can use to estimate how much food to feed your Bullmastiff based on the six factors we have just mentioned.
Our Bullmastiff food calculator uses the dog food formula and feeding guidelines developed by the veterinarians from The Ohio State University Veterinary Medical Center and by veterinarians from the Mark Morris Institute.
Moreover, our calculator knows the calorie content per cup in over 800 popular dog foods (data from the Frankin Animal Clinic). Thus, the calculator can automatically calculate the right amount of each popular dog food that your Bullmastiff needs daily.
Importantly, since the nutrient requirements of the Bullmastiff puppy are different from the nutrient requirements of the adult Bullmastiff, this article contains recommendations on the best food to feed the Bullmastiff at different ages.
Bullmastiff Food Calculator
The Bullmastiff Food Calculator above lets you estimate how much food to feed your Bullmastiff.

.Our dog water calculator lets you estimate how much water your Bullmastiff needs to drink in a day.
How to Use our Bullmastiff Food Calculator
To use the dog food calculator:✔ Select the name of the dog food that you feed your Bullmastiff from the list.
✔ If the name of the dog food that your feed your Bullmastiff is not on the list, then find the bag or can of your dog food, the bag should have written on it how many kcals per cup is in the dog food. Enter this value in the calculator in the place of the dog food name.
✔ Enter the current weight of your Bullmastiff.
✔ Select your Bullmastiff`s age range, activity level, and neuter status.
✔ If your Bullmastiff is overweight or underweight, and you want your Bullmastiff to lose or gain weight, enter the ideal weight of your Bullmastiff for its current age in the `How much you wish your dog currently weighs` box. Leave this box blank if your Bullmastiff is of normal weight.
To know how much Bullmastiffs typically weigh at different ages, check out our article and calculators on Bullmastiff weight and growth.
CONSULT A LICENSED VETERINARIAN FOR PROFESSIONAL ADVICE BEFORE YOU PUT YOUR DOG ON A WEIGHT LOSS OR WEIGHT GAIN DIET.
How the Bullmastiff Food Calculator Works
First, the calculator estimates what is known as the Resting Energy Requirement (RER) of your Bullmastiff.
The RER is the amount of energy that your Bullmastiff needs when it is `resting`, that is when doing nothing. The calculator uses the current weight of your Bullmastiff to calculate your Bullmastiff`s resting energy.
Next, the calculator scales up the resting energy by a factor that corresponds to your Bullmastiff`s life stage (puppy or adult) and lifestyle (activity level, spayed/neutered, etc). This scaled up energy value (called the maintenance energy) is the energy that your Bullmastiff needs to maintain its life when not resting.
Finally, the Bullmastiff food calculator divides the maintenance energy by the amount of energy in one cup of dog food to calculate how many cups of dog food your Bullmastiff needs.
Monitoring Your Bullmastiff`s Growth
The answer from the Bullmastiff food calculator is a starting point number on how much food you need to feed your Bullmastiff.
Start by feeding your Bullmastiff the amount of food recommended by the Bullmastiff food calculator every day.
While feeding your Bullmastiff this daily amount of food, weigh your Bullmastiff at least once a week to ensure that your Bullmastiff is not on its way to becoming overweight or underweight.
If your Bullmastiff is becoming overweight, reduce the amount of food your feed it by 10 to 15 percent, if underweight increase its food by 10 to 15 percent.
You can use our dog weight tracking tool to keep records of your Bullmastiff`s weight. This tool will let you know if the feeding plan is making your Bullmastiff grow normally or abnormally.
You can also check your Bullmastiff body condition score to find out if it is overweight or underweight. Learn how to check your Bullmastiff body condition score here.

How to Measure the Right Amount of Dog Food for Your Bullmastiff
Research has shown that most owners over-measure a cup of dog food. As a result, most dogs owners overfeed their dogs. This is because dog owners do not level off the cup when measuring out the food they give to their dogs.
See how and how not to measure ONE cup of dry dog food in the picture below:
Note that one cup of dog food equals 8 oz of dog food or ~237 milliliters of dog food.

Best Food for Bullmastiff. Bullmastiff Feeding Guide
The Bullmastiff has different nutrient needs at different life stages. Therefore, the dog food that you feed your Bullmastiff at different ages should be the type that is appropriate for its age.
For example, during its puppy stage, your Bullmastiff needs the type of dog food that has been designed to help boost a puppy`s weak immune system.
On the other hand, the adult Bullmastiff should have already developed a good immune system. So, during the adult stage, you should feed your Bullmastiff the type of dog food that has been designed to prolong the life of a dog.
Nevertheless, some dogs still do well eating the same food at every stage of their lives.
However, feeding your Bullmastiff dog food that has been optimized for its age will ensure that your Bullmastiff grows well, lives well, and lives long.
Feeding Guide for the Bullmastiff Puppy: 12 weeks to one year
The dog food that you feed your puppy should have the nutrients that will boost a puppy`s immune system since puppies easily get infected with the disease at this age.
Also, a good puppy food should have the nutrients that support brain development and good vision.
Finally, a good dog food for the Bullmastiff puppy should be the type that will not make your Bullmastiff fat. The puppy food should also help increase the health of your puppy`s bones.

Feeding Guide for Senior Dogs
One way to slow down the effects of aging in dogs is to reduce the amount of food you feed old dogs by 20 to 30% of normal while meeting essential nutrient needs.
Reducing a senior Bullmastiff`s food slows the aging process and reduces the risk for cancer, kidney diseases, arthritis, and immune-related diseases.
AAFCO-Certified Dog Food for the Bullmastiff
No matter which commercial food that you feed your Bullmastiff, make sure that the food is approved by the Association of American Feed Control Officials (AAFCO).
AAFCO is an expert body that rigorously tests dog food to make sure that the dog food is safe.
Also, AAFCO ensures that a dog food has all the nutrients (not just calories) that a dog needs to grow well before AAFCO approves the dog food.
Unlike homemade dog food, most commercial dog foods are AAFCO-approved. Double-check the label of your dog food to make sure it has been certified by AAFCO before feeding it to your Bullmastiff.

How Many Times to Feed the Bullmastiff a Day
When it comes to how many times to feed a dog, there are three different ways to feed the Bullmastiff
One way is to make food available to the Bullmastiff at all times (free-choice feeding).
Another way is to feed the Bullmastiff two or three times a day (food-restricted feeding). This is the feeding method that works the best for most Bullmastiffs.
The third way is to make food available to your Bullmastiff for a short time (about 10 minutes) once or twice a day (time-restricted feeding).
Each of these feeding methods has its advantages and disadvantages, which will be discussed next.
Free-Choice Feeding
This is a feeding method when you make food available to your Bullmastiff all the time.
Note that free-choice feeding is not recommended for large- and giant-breed puppies like the Bullmastiff puppies until these puppies have reached 12 months of age.
Food-Restricted Meal Feeding
Food-limited feeding requires feeding a measured amount of food based on the Bullmastiff’s daily energy requirements divided into two or three meals per day.
This is the method of choice for feeding puppies that are at risk of developing bone diseases due to rapid growth. Restricting the food of a rapidly growing dog will ensure that the dog grows normally.
Time-Limited Feeding
This is a dog feeding method in which dogs are allowed access to food for a short period, usually 10 to 15 minutes, once or twice daily (three times per day for the first month after weaning, then twice per day).
| Method | Advantages | Disadvantages |
|---|---|---|
| Free-choice feeding |

| Food-restricted feeding |

| Time-restricted feeding |

Effect of Neutering/Spaying on How Much Food your Bullmastiff eats
Neutered/spayed dogs tend to get fat twice as easily as intact dogs.
Studies have shown that neutering/spaying may increase your Bullmastiff`s appetite for more food. Also, your Bullmastiff`s physical activity decreases after neutering/spaying. These factors lead to weight gain.
Neutering may lead to more weight gain in male Bullmastiffs because neutered dogs roam less (which means less exercise).
Therefore, the amount of food that you give to a neutered Bullmastiff should be reduced after you neuter your Bullmastiff to prevent weight gain.
Use our Bullmastiff food calculator to calculate how much food to feed a neutered/spayed Bullmastiff.
Effect of Weather on How Much Food Your Bullmastiff Needs
Bullmastiffs that live in cold environments need more food (especially, food high in fat) than Bullmastiffs that live in hot environments.
Hot weather, on the other hand, does not increase the amount of food your Bullmastiff needs. Hot weather only makes your Bullmastiff need more water.
Since most Bullmastiffs live in a temperature-controlled environment as their owners. Therefore, owners do not need to increase or decrease the amount of food they give to their Bullmastiffs based on the outside weather.
Important Note on Treats and Table Food
Because meeting a dog`s nutrient requirements is not the primary goal of dog treats, most commercial dog treats do not contain the essential nutrients that your Bullmastiff needs.
However, a few treats are complete and balanced and are approved by AAFCO, or some other credible dog food regulatory agency. Check the label on your dog treat to know if the dog treat has a complete and balanced nutrient profile.
Nevertheless, dog treats, either balanced or unbalanced in nutrients, are valid sources of calories for your dog. Therefore, if you give your dog lots of treats, you should reduce the amount of the regular dog food that you give your dog accordingly to account for the treats. That way, you will not overfeed your dog.
Also, human table foods do not contain the important nutrients that your Bullmastiff needs for healthy growth.
Also, human table foods may contain very high levels of fat or sodium and other minerals that are harmful to your Bullmastiff.
Moreover, know that when you feed your Bullmastiff table food, you fill your Bullmastiff`s stomach with dog `junk food`. This will suppress your Bullmastiff`s appetite and thereby make your Bullmastiff unable to eat its normal dog food that contains the essential nutrients for your Bullmastiff`s growth.
We do not recommend giving your Bullmastiff table food.
Conclusion
Most commercial dog food labels contain recommendations on how much of the food to feed a dog. However, their recommendations are very general.
Therefore, in this article, we have provided your specific advice on how to properly feed your Bullmastiff.
