Also known as the English Mastiff or the Old English Mastiff, the Mastiff is one of the largest breeds out there. In addition to their massive size, these dogs are also known for their wrinkled snouts and dark facial markings. The Mastiff is a very old breed that was originally developed to guard estates – the breed does very well as a guard dog or watch dog. Even though these dogs are incredibly protective, they are not meant to be aggressive and they can form very strong bonds with family. They need plenty of socialization from an early age, however, and you should start training your Mastiff puppy as early as possible as well before he outgrows you. These dogs do not need a great deal of exercise but a daily walk is recommended to help prevent the dog from becoming overweight or obese.
The Mastiff is frequently called a “gentle giant” because, despite its massive size, the breed is very patient and loving. This breed does sometimes have a tendency to develop a stubborn streak, however, so early socialization and lifelong training is a must. Because the Mastiff is such a large dog, puppies take quite a while to reach maturity – in fact, many breeders keep Mastiff puppies until they are 12 weeks old to ensure that they are fully ready to go to their new homes. The average adult size for the Mastiff is between 27.5 and 30 inches with an adult weight between 120 and 230 pounds. For a dog of this size, you shouldn’t be surprised to learn that the breed’s average lifespan is between 8 and 10 years. These dogs are prone to a number of health problems including bone and joint disorders like hip dysplasia and elbow dysplasia as well as bloat, heart conditions, and various eye problems.
As a giant breed, the Mastiff requires a lot of calories on a daily basis to maintain his lean muscle mass. Because these dogs are not overly energetic, however, there is a fine line between feeding this breed enough and feeding him too much. You also want to make sure that your Mastiff’s diet provides support for his bones and joints as well as probiotics for healthy and regular digestion. The best way to ensure that your Mastiff’s specific nutritional needs are met is to select a large-breed or giant-breed formula. Keep reading to learn more about the nutritional requirements for Mastiffs and to receive recommendations for quality dog food brands for this wonderful breed.
General Nutritional Recommendations for Mastiffs
Feeding your dog a high-quality diet is very important no matter what kind of dog you have. With a massive breed like the Mastiff, however, it is even more important because if your dog doesn’t get the nutrients he needs, his body won’t be able to function properly. When it comes to a balanced diet for dogs, the three main nutrients you need to worry about are protein, fat, and carbohydrate. Protein and fat should come primarily from animal-based sources to ensure maximum bioavailability. Your dog has a limited ability to digest plant products, so any plant-based ingredients in your dog’s diet should come from highly digestible sources. In fact, your dog’s food should provide no more than 5% crude fiber because too much more than that could cause digestive problems.

Protein is the most important nutrient for dogs, so it should be at the top of the ingredients list for your dog’s food. The Merck Veterinary Manual recommends a minimum protein content for adult dogs of 18% and 22% for puppies, with a 5% minimum of fats for adults and 8% for puppies. For giant breeds like the Mastiff, the more protein you can squeeze into your dog’s diet, the better. Protein is absolutely necessary to help your dog maintain his lean muscle mass. While more protein is always better for Mastiffs, you need to be careful about feeding him too much fat. Fat is a concentrated source of energy for dogs but it contains 9 calories per gram, compared to just 4 calories per gram for protein and carbohydrate. You don’t want to go overboard on fat for your Mastiff because it could contribute to unhealthy weight gain or even obesity.
When it comes to carbohydrates in your Mastiff’s diet, you want to make sure that they come from digestible sources. Whole grains like brown rice and oatmeal are generally considered to be digestible for dogs, though some dogs have allergies or sensitivities to grains. For grain-free options, look for a dog food made with sweet potatoes, peas, or other starchy vegetables and legumes. Carbohydrates provide dietary fiber to support your dog’s digestion but they also provide some vitamins and minerals. Still, a high-quality dog food will contain nutritional supplements to ensure complete and balanced nutrition. Things like chelated minerals are always a valuable addition, as are dried fermentation products – these act as probiotics to provide digestive support. Avoid any product made with low-quality ingredients, non-nutritive fillers, and artificial additives.
Special Dietary and Nutritional Concerns
Because the Mastiff is such a giant breed, you need to make sure that your dog gets enough food to support his mass. Even as a puppy, your Mastiff will probably eat 4 cups of food per day, or more – once he reaches adulthood it could be as much as 12 cups a day! You should not just fill your dog’s bowl with food in the morning and walk away, however – your Mastiff’s meals should be evenly spaced throughout the day. With giant dogs like the Mastiff you need to walk the line between feeding your dog enough and feeding him too much. If your dog doesn’t get enough food, he may not grow and develop properly. On the other hand, if you feed him too much, he could grow at an excessive rate which might put too much strain on his developing bones and joints. Overgrowth can increase your dog’s risk for developing musculoskeletal issues as an adult.
When determining how much to feed your Mastiff, you may find it easier to think in terms of calories rather than cups of food. Each pet food product is formulated differently – you may have one product that contains about 350 calories per cup and another that contains 500 calories. Most adult dogs need about 30 calories per pound of bodyweight to maintain their lean muscle mass. For large and giant breeds like the Mastiff, however, you are probably looking at something closer to 20 calories per pound. Still, that adds up to quite a sizable number! Even if your Mastiff stops growing at the low end of the breed’s size range (about 120 pounds), he could still be eating 2,400 calories per day. If he weighs more than 200 pounds, he could be eating well over 4,000 calories per day. Determine your dog’s calorie needs based on his weight, then calculate how much to feed him on a daily basis using the feeding recommendations on the pet food package of your choice.
In addition to making sure that your Mastiff gets enough calories, you also need to make sure that he gets the right ratio of protein to fat. His diet should consist of at least 18% protein (but more is always better) to help him maintain his lean muscle mass. Look for a product that provides moderate fat content (a minimum of 5% but no more than 15%) to give your Mastiff the energy he needs without going overboard. Your Mastiff can also benefit from a formula that is supplemented with glucosamine and chondroitin for bone and joint support as well as probiotics for healthy digestion to ensure that his body is able to absorb and utilize the nutrients from the food he eats. To make sure that all of these needs are met, your best bet is to select a giant-breed specific dog food formula.

As one of the largest dog breeds out there, the Mastiff is not the right breed for everyone. Even if you are able to control your dog through obedience training, that is not your only challenge. Mastiffs are massive dogs so they need a lot of food, particularly protein-rich food, in order to support their lean muscle mass. If you cannot afford a high-quality dog food (especially in the quantity needed for a dog as large as the Mastiff), you may want to consider another pet. If you are able to commit to giving your Mastiff the best care possible, however, you will find that he is a loving and loyal companion. To make sure that you get to enjoy as much time as possible with your Mastiff, be sure to feed him a high-quality diet – ideally a large or giant breed formula.
