Bullmastiffs are large, muscular dogs that make great protectors because of their intimidating appearance and fearlessness. Underneath their appearance though, Bullmastiffs are a lovable breed which make a great addition to any family. Although they are a little bit aloof toward strangers, this breed will be friendly toward their family and people that are familiar to them.

Thus early socialization is recommended to prevent and stop aggressive behavior!

Bullmastiffs are a breed with a long working history, originally being trained to scare off poachers and later used as police and military dogs, service animals, and hunting dogs. Their protectiveness makes them great and loyal guard dogs, but it also means that they need to be trained and exposed to other dogs and various environments early.

Bullmastiffs also have a lazy side (haha) for a large breed, they are pretty content to hang around at home not doing too much!

Bullmastiff Diet and Nutrition Guide

What to feed a Bullmastiff?

Both breeders and trainers consider a raw diet is the best option for the Bullmastiff. Food manufacturers spend millions in research to study the nutritional needs of dogs and developing premium foods.

So if you don’t have the time it takes to spend hours preparing your pet’s food, you should consider a high-quality dog food made with natural and wholesome ingredients.

More expensive brands may be tastier and easier to digest, but there's nothing wrong with the cheap stuff if it's "complete and balanced".

Since Bullmastiffs are prone to a few different health conditions and sensitivities, owners should pay close attention to their diet. A high-quality diet, free of artificial additives and chemical preservatives is vital for the health of your Bullmastiff.

The ideal diet for Bullmastiffs is one that is moderate in high-quality protein. Excess protein with the Bullmastiff has also been known to cause other related health issues.

Since the Bullmastiff is prone to gaining weight, it’s best to keep him on a diet that consists of mainly lean protein like turkey, fish or other game protein. Maintain protein levels around 21-25%.

Fat is essential since it protects vital organs and is another source of energy. Maintain fat levels around 15%+.

Carbohydrates are necessary as it provides energy as well as fiber to help with your dog’s gastrointestinal tract. Avoid foods containing corn, instead look for sweet potatoes, oatmeal and rice as good and healthy sources of complex carbs. Keep carbohydrates around 40-45%.

Finally vitamins and minerals are required for the body to carry out essential metabolic processes. So ensure plenty of these!

Bottom line, choose a brand that meets your dog’s needs and is priced for your budget and stick to it.

Blends like Taste of the Wild, Blue Basics, Merrick Limited Ingredient Diet and Wellness Simple are great options for Bullmastiffs because of their limited, natural ingredients.

Protein and healthy fruits and vegetables are the first ingredients in these premium dog food blends, which are specially designed to help dogs with digestive issues and sensitivities.

Feeding Tips for Bullmastiffs

Bullmastiffs should be fed small meals throughout the day to prevent bloating.

Even though it is recommended that large breed dogs get two meals a day, once in the morning and once in the evening, Bullmastiffs are a little different. 

Owners can choose to go with three small meals a day if they find their dog has sensitivities and this works better for them. If your Bullmastiff is already overweight, feeding them smaller meals multiple times a day will help keep his metabolism up and help burn calories throughout the day.

Always use a measuring cup since this breed is prone to gaining weight.

To figure out the right amount of food to feed a Bullmastiff, you can consult the feeding information on your chosen dog food and go per your dog’s weight to start. Afterwards, you can adjust it based on your dog’s individual needs and energy levels.

Leave their feeding and water bowls on lower ground and not elevated. Since large breeds are prone to dog bloat, recent studies point to lowering food bowls to help with food digestion.

Finally, since the Bullmastiff has a square muzzle they have difficulty eating out of a flat bowl so instead use a round bottom bowl.

How much food to feed a Bullmastiff?

Unlike most other breeds that are similar in size, Bullmastiffs are not particularly energetic. That said they require regular walks but are not allowed to exercise too strenuously given their joint sensitivities or overeat since this can lead to host of health problems for them.

A high-quality and concentrated premium dog diet with fresh meat as first ingredient and using either oatmeal, rice or sweet potatoes as the carbohydrate source is strongly recommended.

Owners should make sure to feed their Bullmastiff a high-quality diet but watch the amount they are fed, because overfeeding could potentially lead to weight and other health problems.

An overweight dog is an unhealthy dog!

Start first by finding out what your dog’s ideal weight is and then calculate how many calories he would need at that weight and then just feed him the food at the reduced calories paying attention that their intake reduces in the winter and increases in the summer.

An average male Bullmastiff dog weighs between 110- 130 lbs (50-59 kg) while a female Bullmastiff weighs between 90- 110 lbs (41-50 kg).
