English Mastiff

Keeping a Mastiff has advantages and disadvantages. One of the negatives to owning one of these dogs is the amount of food they eat and the importance of providing them with the right nutrition to maintain their health.

A full-grown Mastiff can weigh up to 122 pounds, but each dog will be different in their build, metabolism, and activity level, which means you have to customize your feeding plan to fit the needs of your dog. It can be a daunting task to figure out which brand of food is ideal for your dog while making sure it provides the needed nutrients to keep your dog healthy.

This review list features nine of the best dog foods for the Mastiff, discussing the pros and cons of each and offering tips and considerations to keep in mind before making your final decision.

But if you don’t have a picky eater, it may not be an issue.

    Buyer’s Guide: Selecting the Best Dog Food for Mastiffs

    This portion lists considerations to keep in mind when searching for the ideal dog food for your Mastiff. Knowing about the general nutritional requirements needed for this breed is a great starting point before considering any special dietary concerns. Here’s how to choose the best food for Mastiffs:

    Mastiff Nutritional Needs

    The nutritional requirements will depend upon what stage of life your dog is currently in. Puppies require different amounts of nutrients compared to senior dogs. You will also need to feed your puppy more often than you would an adult. There are certain ingredients that every Mastiff requires — these are proteins, fats, calories, and micronutrients.


    A diet that features a good-quality protein is ideal, such as animal protein. Whole grains and many vegetables can also provide protein, though they shouldn’t be the number-one ingredient. Protein helps build muscle mass, which is a requirement to keep your dog strong and limber. Meat meals contain a higher amount of protein than fresh meat, which is why you will sometimes see both in the ingredients.


    Animal fat is a common ingredient that provides energy to your dog, as well as flavor to the kibble. Fatty acids are great for healthy skin and coat, while puppies benefit from DHA (an omega-3 fatty acid), which is essential for brain and eye development. Other examples of fat are from fish oil, coconut oil, and canola oil. You don’t want to provide too much fat, or your Mastiff could become overweight.


    How many calories your dog needs will depend upon their activity level and metabolism. An average adult will need 20 calories per pound of body weight, which could add up to 2,000 calories for a 100-pound dog. Know how many calories are in 1 cup of food so you can feed accordingly. You can speak with your veterinarian to figure out the caloric intake if you are unsure. These needs can be different if your dog suffers from any health conditions.


    Calcium and phosphorus are needed for healthy bones, and the addition of glucosamine and chondroitin are important to protect the joints. It’s also a good idea to include taurine to protect the heart. A well-rounded diet will include the right number of vitamins and minerals to keep the immune and digestive system functioning correctly.

    Mastiff Dietary Concerns

    Due to their size, Mastiffs tend to suffer from joint and bone issues and heart disease. By feeding them a good diet that supports these systems, you will help your dog stay healthy. Mastiffs can also bloat easily, so it is important to give them food that requires them to slow down when eating. Some dry foods offer larger and courser kibble to help with this.


    An adult Mastiff can consume up to 10 to 11 cups of food per day, so it can be expensive to feed your large dog. You will have to find a balance between providing high-quality food that meets nutritional needs and one that fits your budget. It is not an impossible task, but be aware you will be spending more money feeding a larger dog than you would otherwise.

    Feeding Tips

    • Stick to a feeding schedule and evenly space the meals throughout the day.
    • It is not recommended to provide a self-feeder because they will overeat if given the chance.
    • A diet of at least 18% protein is ideal for maintaining muscle mass.
    • Puppies will need to eat more frequently.
    • Feed age-appropriate food that meets the nutritional needs of larger breeds.
