Top 10 Best Dog Food for Mastiff

Top 10 Best Dog Foods for Mastiffs

If you have a Mastiff, you’re well aware of their size and that they can consume quite a lot of food. But the thing about Mastiffs is that they are prone to obesity, and large dogs in general often don’t live as long as smaller ones. With that being said, it’s important to feed them high-quality and nutritious dog food in order for them to live a long and healthy life.

Mastiffs are also muscular dogs, so the best food for them should be high in protein in order to keep their muscles in good shape. The food should also be low in fat to help them maintain a healthy weight. Luckily, you don’t have to spend time searching, as we’ve compiled a list of the best dog food for Mastiffs along with reviews of each one to help make your decision easier.

Is wet food better or dry food?

Providing that they meet the nutritional needs of your Mastiff,  both wet and dry foods are good for your giant friend. The only difference is that of moisture.

How many times a day should I feed my Mastiff?

Two evenly spaced meals per day are preferred and help to establish a routine for your Mastiff. Dogs love routine.

Is potato in dog food hazardous?

Baked and cooked potatoes are fine. It is the raw potato or potato plants that your dog needs to avoid to stay healthy and free from allergens.

What foods can cause heart problems?

Most larger breeds of dogs are susceptible to heart diseases, which means that your Mastiff is at risk too. Avoid fatty foods to make sure they remain safe and healthy.

Is grain-free dog food better for my Mastiff?

A grain-free diet is a good option for those Mastiffs with allergies or sensitive stomachs. It’s an easily digestible option, but keep in mind though that all dogs are individuals and need a diet catered to their individual needs.

How much should I feed my Mastiff?

A typical mastiff consumes about 10-11 cups of food each day, that means about 2 pounds of food every single day. Just be careful of overfeeding or underfeeding your pup.

What is the best food for English Mastiffs?

A diet rich in protein, fiber, and a small amount of fat is perfect for an English Mastiff. Any of the top eight foods I have listed here can be a perfect fit for your Mastiff.

How much should I feed my English Mastiff puppy?

It depends on the weight and age of your puppy. A new puppy should be fed 3-4 times a day, about 3/4 to 1 cup each time. Ensure that the diet has all the right amounts of proteins, fiber, and fats.

Buyer’s Guide: How to Choose the Best Dog Foods for Mastiffs

  • Now that you’ve seen all of these different dog foods that we think are good for Mastiffs, you may be left with more questions than answers about which one to choose. After all, we’ve given you a lot of information about different ingredients and nutrients that are found in each of these dog foods.
  • You may also be trying to figure out which one is going to be the easiest on your wallet while still giving your Mastiff the nutrients that he needs to stay healthy. But don’t worry because we’ve created this Buyer’s Guide with the hopes to answer any questions you may still have with the hope that it can help you choose the best food for your dog.


One of the first things you should pay attention to when it comes to choosing dog food is the ingredients. The ingredients are what are going to give your dog the nutrients that he needs to stay healthy. Here are some key ingredients and nutrients to look for.

Meat-Based Proteins
  • Dogs, in general, need food that is high in meat-based proteins, as these contain the most important nutrients needed in order to keep your dog healthy.
  • But considering that Mastiffs are such large dogs and often have a lot of muscle mass, feeding them food that is high in protein is essential for helping to keep them in shape. The best dog foods should have some kind of meat listed as the first ingredient, but preferably as the first three ingredients. Steer clear of meat by-products if they are not clearly named as this allows variations that might affect the quality. Prefer food with clearly named organs such as “heart” or “liver”.
  • We should also mention that it’s important to choose food that contains meat that your dog likes; don’t buy food that is higher in protein if your dog won’t eat it. But when it comes to high-protein dog food, they come in a variety of flavors so you’re sure to find something your dog loves.
Plant-Based Ingredients

Dog food that contains, fruits, and vegetables are also better because these ingredients often provide nutrients that meat does not. Examples include antioxidants, vitamins, and minerals that help keep different parts of your dog’s body healthy, such as the brain,  skin, coat, and immune system. But, these ingredients are not as important as meat, so again, always choose a food that contains meat as the first ingredient.


Finally, you may want to consider looking for food that contains DHA, especially for Mastiff puppies. DHA is an omega-3 fatty acid that is commonly found in fish or fish oil. All puppies and even adult dogs can benefit from DHA as it helps support brain development in puppies, which can make training them easier and can help older dogs maintain a healthy heart and vision.

Glucosamine and Chondroitin

Being large dogs, Mastiffs are prone to joint problems such as hip and elbow dysplasia, which can lead to them developing other problems such as arthritis. Because of this, you may want to choose a dog food that contains glucosamine and chondroitin, which help support joint health and can reduce arthritis pain if it were to develop.

Health and Age

  • Another important thing to consider when choosing food for your Mastiff is his health and age. Mastiffs aren’t the most active dogs, so they can easily become overweight if they aren’t fed a balanced diet. You don’t want to choose food that is high in fat and calories, especially if your Mastiff already weighs a bit more than he should. It’s a good idea to talk to your veterinarian if your dog is overweight to see what amount of fat and calories he or she recommends before choosing dog food.
  • Something else we’ve mentioned throughout our reviews is grain-free dog food vs. food that contains grains. Grains aren’t necessarily bad for dogs, but some dogs can be allergic or have sensitivities or intolerances of them, particularly grains that contain gluten. You know your dog, and if he or she has trouble eating or digesting certain foods, it may be better to try a grain-free option.
  • Finally, consider the age of your dog, as puppies or senior Mastiffs may need different food than healthy adult dogs do. Puppy food formulas often contain different nutrients that are crucial for healthy development and tend to contain smaller kibble as well to make the food easier to eat. Food for senior dogs tends to contain smaller and softer kibble as well but is also lower in fat so that it is better suited for a slower metabolism.


  • The last thing to consider when choosing dog food for your Mastiff is your budget. Remember that high-quality dog food is the best thing for a Mastiff, and these foods are often pricey. However, some high-quality dog foods are more budget-friendly than others, and many dog foods come in different sized packages as well in case you need to go cheaper for a month or two.
  • You should also remember that just because certain dog food is more expensive, it doesn’t mean it is better for your dog than a cheaper alternative. It all depends on your dog and what nutrients and ingredients will benefit him the most. Many high-quality dog foods are affordable while still being nutritious
