    1. Nom Nom Dog Food Beef Mash Recipe – Best Overall

    Nom Nom Fresh Dog Food Turkey Fare Recipe

    Nom Nom Beef Mash is our pick as the best overall dog food for Mastiff puppies. It uses all human-grade ingredients, like potatoes and carrots, and your pet will receive plenty of protein from fresh beef, the first ingredient, as well as from eggs and peas. These ingredients will help your pet stay healthy, and there are other great ingredients, like omega fats from fish oil, which will help promote a shiny coat and provide many other health benefits.

    The cost of this food is higher than the brands that you will find at the grocery store, and you will also need to order it online. The other downside of this brand is that it requires freezer space to keep the food fresh; in some cases, it might defrost on the way to your home.

    • Ground beef is the first ingredient
    • Real vegetables
    • Omega fats
    • No artificial colors or chemical preservatives
    • Pricer than regular kibble

    2. Nutro Wholesome Essentials Large Puppy Food – Budget Buy

    Nutro Wholesome Essentials Large Puppy Food

    Check Price on Chewy
    Check Price on Amazon

    Here we have the best food for Mastiff puppies for the money, Nutro Wholesome Essentials Large Puppy Food. Not only does it offer a high protein content for the money, but it is also farm-raised chicken, meaning it is a good quality meat source too. All ingredients are made from non-GMO sources, meaning no nasty preservatives or additives – only fresh ingredients here.

    This kibble is designed for large puppies, meaning it has just the right amount of calcium and phosphorus to control bone growth. It has a variety of added vitamin and mineral supplements for your Mastiff puppy’s growing immune system too.

    The only reason this choice didn’t make it to first place is that the grains that it uses aren’t as gentle or as digestible as the grains used in Blue Buffalos. But if your Mastiff puppy doesn’t have a sensitive digestive system, this makes a great alternative.

    • Farm-raised Chicken
    • Non-GMO ingredients
    • DHA and ARA for brain development
    • Optimum levels for controlled growth
    • Uses high amounts of peas and lentils

    3. Instinct Raw Boost Large Puppy Food


    Check Price on Chewy
    Check Price on Amazon

    In third place, we have Instinct Raw Boost Puppy Formula. This dog food is more on the expensive end of the products we have chosen for the Mastiff puppy. But for those who aren’t concerned with a budget, this is an excellent choice to consider.

    It has the highest protein content on this list thanks to the variety of meat sources, such as chicken, fish, lamb, and eggs. It also lists a variety of freeze-dried organs, which are full of nutrients and big meaty flavor. The freeze-dried toppers add texture to their bowl too. Reviewers comment on how their large puppies cannot get enough of this kibble. But few said that it was too rich for their pup.

    Egg products and fish oils provide DHA and ARA for healthy puppy development and a healthy coat. This kibble is a grain-free product, and it contains no potato, peas, lentils, corn, wheat, or soy, which are common allergens in sensitive dogs. It is 100% natural, too, so you can be sure their digestive system is cared for.

    • High protein content
    • Freeze-dried organ ingredients
    • High omega fats for joint support
    • High energy for strong puppy growth
    • On the expensive side
    • Can be too rich for some dogs

    4. Blue Buffalo Life Large Puppy Dry Dog Food 

    Blue Buffalo Life Large Puppy Dry Dog Food 

    Check Price on Chewy
    Check Price on Amazon

    Blue Buffalo are creators of some of the very best dog nutrition around, and this is our top pick for the Mastiff puppy. The first two ingredients in the list are rich protein sources – deboned chicken and chicken meal. High-quality protein sources at the beginning of an ingredient list is a strong sign of a good quality product. And your Mastiff puppy is sure to go crazy for the meaty taste.

    This kibble is a grain-inclusive option, which uses gentle fibers and grains such as brown rice, oatmeal, and barley. This kibble also lists many omega fatty acids, such as fish meal, flaxseed, and fish oil, which provide support for the joints and make their coat soft. The fish ingredients are also a great source of DHA and ARA, which are crucial nutrients for the puppy stage.

    It also includes Blue Buffalo’s exclusive LifeSource Bits, which are packed full of antioxidants needed for healthy development and to strengthen the immune system. However, according to reviews, some dogs aren’t a fan of them and tend to eat around them. And being designed specifically for large puppies, it has the optimum level of calcium and phosphorus for controlled bone growth.

    • High-quality protein sources
    • Superfood blend for strong immunity
    • DHA and ARA for brain developmen
    • Optimum levels for controlled growth
    • Full of omega fats for overall well being

    Check Price on Chewy
    Check Price on Amazon

    This kibble does exactly what it says on the tin and offers your Mastiff puppy with complete wellness. The first two ingredients are deboned chicken and chicken meal, with plenty of muscle growing power and energy for cell growth. Salmon and salmon oil are also listed further down, which are rich in glucosamine for joint support as well as overall health.

    It has a long list of superfoods, such as spinach, carrots, apples, blueberries, and sweet potato. All of which are great for your Mastiff puppy’s developing immune system and keeping them fighting fit against illnesses. As well as added vitamin and mineral supplements for healthy cell reproduction.

    This kibble also focuses on their digestive system, with added probiotic ingredients and prebiotic fiber. It also provides a guaranteed level of taurine with every pound of kibble, which helps to keep the cardiac system healthy. This product is one of the more expensive products, but it is a premium product that is 100% natural.

    • First two ingredients are chicken protein
    • DHA and ARA for cognitive and eye function
    • Antioxidant-rich with fruits and veggies
    • Taurine listed for a healthy heart

    6. American Journey Grain-Free Puppy Dog Food

    American Journey Grain-Free Puppy Dog Food

    Although American Journey’s packaging doesn’t explicitly state that it is suitable for large breed puppies, don’t let this put you off. It follows the AAFCO guidelines for large breed puppies meaning that it has the optimum calcium and phosphorus level to control bone growth. So, it is an excellent option for Mastiff puppies.

    The first three ingredients are deboned lamb, chicken meal, and turkey meal, making it protein-rich. It also has a very high glucosamine content which is excellent for the Mastiff puppy and their pressurized joints. Sweet potatoes, blueberries, and carrots provide fiber and plenty of vitamins and minerals for a healthy immune system. With probiotic and prebiotic fiber, their gut is well cared for.

    The only thing that we don’t like when it comes to this product is that it uses several pea ingredients, which is a tactic known as ingredient splitting. This tactic is often used to boost the overall protein content. But with only two pea ingredients, this is just us being picky.

    • Suitable for large breed puppies
    • High protein content
    • High in glucosamine for heavily laden joints
    • Smaller bag
    • Lists various pea ingredients

    7. Hill’s Science Diet Puppy Dry Dog Food

    Hill's Science Diet Puppy Dry Dog Food

    Check Price on Chewy
    Check Price on Amazon

    Hill’s Science Diet is tried and tested the world over. Canine nutritionists have studied the needs of large breed puppies, and this is the formula that they think offers Mastiff puppies the best nutrition. If you believe in scientific methods over natural recipes, this is an excellent choice for you.

    Chicken meal is the first ingredient, which is always a great sign, and it means that your Mastiff puppy’s muscles and growth are supported during their most crucial life-stage. Fish oil, with biotin, folic acid, and vitamin E, are listed to provide a luscious coat and healthy organ development.

    This recipe is not a natural one, which may put some owners off. However, with its high ratings and proven formula, this recipe is a big hit with large breed pups.

    • Chicken meal is the first ingredient
    • Added vitamins and mineral supplements
    • Uses artificial liver flavors
    • Relies heavily on wheat and corn

    8. Eukanuba Puppy Dry Dog Food

    Eukanuba Puppy Dry Dog Food

    Eukanuba is a well-known brand, and here they have created a kibble with active large breed puppies in mind. Chicken and chicken by-product meal provide protein and energy. Fructooligosaccharides are also listed, which is a probiotic ingredient used to aid healthy digestion, which in turn, lowers gas too. And Mastiff puppies know how to trump!

    Fish oil and egg products are listed, so you can be sure that your Mastiff puppy’s eyes and brain will develop as they should do. The calcium and phosphorus level is optimized to ensure that they don’t grow rapidly, avoiding extra pressure on the joints.

    We don’t like that Eukanuba uses chicken by-products, as they are a lower quality protein source. Additionally, corn and wheat are listed quite high up in the ingredients list, but again, this is only an issue for those Mastiff puppies who have sensitive stomachs.

    • Real chicken is the first ingredient
    • Lists eggs and fish oil for DHA needs
    • Uses chicken by-products
    • Corn and wheat listed

    9. Purina Pro Plan Focus Puppy Dry Dog Food

    Purina Pro Plan Focus Puppy Dry Dog Food

    Check Price on Chewy
    Check Price on Amazon

    Chicken is the first ingredient on this dog food list, which is an excellent sign of a good quality product. It also means your Mastiff pup gets all the amino acids they need to build strong, healthy muscles. It is designed for large breeds, with optimum levels of calcium and phosphorus.

    Dried egg product, fish meal, and fish oil provide plenty of DHA and ARA for healthy brain and eye development. The kibble is fortified with vitamins and minerals for healthy and steady growth.

    What we don’t like about this product is that it uses by-products, which are inferior sources of meat protein. Another point that we aren’t too keen on is that the by-product is an unnamed source, which isn’t ideal for those Mastiffs with specific intolerances. But, with good reviews from customers, this doesn’t seem to put most pups off.

    • The first ingredient is chicken
    • Live probiotics for healthy digestion
    • Uses unnamed meat by-products
    • Relies on heavily on corn

    Buyer’s Guide: Finding the Best Food For Your Mastiff Puppy

    Here we are going to talk you through everything you need to know about the nutritional needs of your Mastiff puppy. As well as what to look for in a good quality puppy product. Although we have provided you with our suggestions for the Mastiff puppy, you need to know yourself why it is a good product and why it is the right one for them. So, let’s take a look.

    Mastiff Puppy Food Only

    Just like newborn babies, Mastiff puppies need certain nutrients that will help them to develop healthily. They need higher protein content compared to adults. The MSD Veterinarian Manual states that all puppies need to eat a protein content of at least 22%. Protein provides amino acids, which are the building blocks for a developing body, as well as energy for puppy growing power.

    Mothers milk is full of docosahexaenoic acid (DHA) and arachidonic acid (ARA), which are known to promote the healthy development of cognitive and cardiac function. Ingredients such as fish oils and egg products are rich in DHA and ARA, and puppy kibbles have a higher amount of these nutrients when compared to adult kibbles.

    All life stage kibbles aren’t specifically designed with puppies in mind, and you risk feeding them a kibble that isn’t going to provide them with what they need to grow. Their puppy development stage is their most essential nutritional stage, and getting it right will set them up for a healthy life.

    Always Buy a Large Breed Kibble

    When it comes to large breed puppies, you must feed them a kibble that is either designed for large breed puppies or one that states it meets the standards set out by the Association of American Food Control Officials.

    Large breed puppy kibbles offer a controlled level of calcium and phosphorus, which helps to control the speed at which the bones grow. Small and medium-sized pups grow at a much steadier pace, so the ratios aren’t controlled. Getting these levels right is known to prevent the development of bone diseases, such as hip dysplasia, which is prevalent in the Mastiff breed.

    By feeding them anything but a large breed kibble, you are increasing their risk of developing these diseases. So really, nothing else will do for the Mastiff puppy.

    Glucosamine is Super Important

    Always look for a kibble that states it has glucosamine in it. Glucosamine is essential for dogs that are expected to be large or giant breeds, which is 50 pounds plus. Glucosamine is an amino sugar that naturally cushions the joints. Without it, their joints will rub and deteriorate, causing arthritis and other joint pain.

    So, by topping your Mastiff puppy up with glucosamine from an early age will help to keep their joints supple and young at heart, no matter how Zorba-like they become.

    Ingredients that are a great source of glucosamine are meat meals, green-lipped mussels, flaxseed, and fish oils. You can also buy fish oil supplements too.

    High-Quality Protein is Key

    High-quality protein is also really important when it comes to feeding your Mastiff puppy. High-quality sources of protein are real meats, such as chicken, turkey, lamb, or fish.

    Meat meals are also a great source, and they are concentrated too, meaning your pup gets more protein bang for your buck.

    Meat by-product meals aren’t high-quality meat sources, but some brands use them. Brands such as Hill use them in their science diet, and with their high reviews, it isn’t bad for your pup, but it just isn’t as natural.

    When it comes to unnamed by-product meals, you need to consider your Mastiff puppy’s diet needs. For example, the Purina suggestion above lists “poultry by-product meal.” But what if your pooch is allergic to turkey, but not chicken? Unfortunately, with this unnamed ingredient, you cannot be sure what it is, so this rules this option out entirely for those with allergies.

    Consider Their Needs

    Following on from the above point, just like us humans, all Mastiff puppies are different. They all have different taste preferences and intolerances, and they also all have different dietary needs. Some may be allergic to corn or wheat, and some might need a grain-free diet. Some may be allergic to chicken, and some can eat absolutely everything.

    Wherever your Mastiff puppy stands, be sure to feed them a kibble that suits their needs. Nutrition is the easiest way to keep them healthy, so it’s essential to get it right.


    Yes, budget is a concern for every dog owner out there, and getting the best bang for your buck is crucial. But it is also important to remember that nutrition is often the easiest way to keep them healthy.

    By feeding your Mastiff pup a high-quality kibble, you are setting the foundations for a healthy body and lifestyle. And although a high-quality kibble is more expensive than a budget store kibble, you could be saving yourself a lot of money in the long run.

    This is especially true when it comes to the colossal Mastiff pooch and their predisposition to hip dysplasia and other bone conditions. By lowering the risk of these, you could save yourself thousands in vet bills when they are older.

    Plus, higher quality often means bigger meatier taste, and they’ll love you for it! If you’re wondering how much to feed a Mastiff puppy, take a look at our puppy feeding guide (with charts!)!
