How Much Should A Mastiff Puppy Eat?

You might be unsure about the proper feeding regimen for your new Mastiff puppy.

However, if you get the hang of it, it's not such a difficult process.

Keep in mind that Mastiffs mature quickly, especially in their early phases.

In these stages, there are also nutritional requirements.

Remember that you should always expect to alter any guideline to match your puppy's individual needs.

Genetics and physical activity have a role in how each puppy develops.

As a result, feeding should be modified accordingly.

A Mastiff puppy will eat his mother's milk for the first few months of his life.

When it comes to solid food, it's best to start with 1-2 cups when he's about 2 weeks old.

You should be giving him roughly 12 cups of food when he is about 12 years old.

As he grows, this will be gradually increased.

  Here Are The Feeding Suggestions For A Mastiff Puppy

Many dog owners want to determine their dog's RER, which stands for Resting Energy Requirements.

You can find out his RER by multiplying his body weight by 3/4 and multiplying the result.

In order for the RER method to function, you'll need to weigh your Mastiff puppy as he grows in order to make the calculations.

You should also use this as a rough estimate while keeping an eye on your puppy's health.

Simply looking at the dog food package and following the directions based on age and weight is an excellent approach to figure out your puppy's feeding regimen.

Specific breeds are even listed on the packaging of some dog meals.

As a Mastiff grows, the quantity you give him will undoubtedly fluctuate.

Depending on how he's doing, you may always change the amount of food you gave him.

2 Weeks Old Mastiff Puppy

Your Mastiff will be expected to be suckling from his mother at this period, which is very delicate.

As a result, you will not be responsible for much feeding.

For warmth, he will cling to his mother and littermates.

If your Mastiff mother rejects your pups, you'll be expected to respond quickly as the dog owner.

Most of the time, this will be the pup who is the youngest.

Because you now have responsibility for this puppy, you must keep him warm and feed him.

You can use a heating pad grateful you were placed under a blanket to keep his core temperature warm and consistent in place of his mother's warmth.

You'll also have to feed him a canine milk substitute. This can be done with either a bottle or a tube.

4 Weeks Old Mastiff Puppy

You will note that your Mastiff will go through fast changes as he develops at this important stage.

This is especially true for Mastiff dogs due to their rapid growth rates.

At this point, he should be weaning and transitioning to a solid meal, leaving the liquid diet behind.

Make this adjustment as seamless as possible because your Mastiff requires sufficient nourishment, but if there are any rapid changes, he may refuse to eat.

If you don't handle this properly, he could go without the nutrition he requires to grow.

Make sure his food isn't too tough for him.

He can't eat a lot of the kibble on the market since it's too hard for him.

The consistency of his diet should be similar to mashed potatoes or a thick soup.

So you can mix the kibble with the liquid meal you've made, but keep an eye on him to make sure he's okay.

During this period, your puppy will be learning how to chew.

3 to 4 cups of food should be spaced out throughout three to four meals.

It is not uncommon for Mastiffs to revert to their mother's milk, but as he grows accustomed to solid food, this will fade away.

Remember to keep with the same brand when you introduce solid food because abrupt changes may cause him to reject the meal he so sorely needs.

It could potentially irritate him.

6 Weeks Old Mastiff Puppy

Your Mastiff will continue to grow quickly at this point and will be used to solid food.

As nursing is no longer required, he will separate from his mother.

Because he is expected to be more active as he explores his surroundings, keep an eye on him and boost his food.

He should have 4-5 cups of food every day, divided into three to four meals.

At each feeding session, observe how 1-1 12 cups work for him.

If it doesn't work and he's either too hungry or doesn't eat, make the required adjustments.

8 Weeks Old Mastiff Puppy

As your Mastiff grows, you can now give him roughly 6 cups of food, divided into 3 to 4 meals.

As he explores and learns his boundaries, he will become more lively and playful.

Physical exercise, in addition to eating, is critical for appropriate bone and muscle development at this stage.

They will be capable of surviving without their moms, who will no longer be required to feed and groom them.

10 Weeks Old Mastiff Puppy

You can start feeding your puppy roughly 7 cups of food per day at this point.

Observe how he handles three to four times each day with this increment, and then gradually increases to three times per day with the same amount of food.

Remember that Mastiffs are prone to bloating, so feeding them too much food at once can cause problems.

This is why you must keep track of how much food you give them at any one time.

This isn't to say that you should starve them.

Look for symptoms that kids aren't getting enough food.

You'll notice if they start searching through garbage or pacing up and down on the floor hunting for food.

You'll also be able to see if they're too skinny.

12 Weeks Old Mastiff Puppy

This is the time to raise your Mastiff's food intake to 8 cups per day.

Even if you feed him three times a day, you should keep an eye on him to make sure he doesn't get bloated or have an upset stomach.

When it's time to eat, he should be eager to do so as a sign of a good appetite.

For proper development, make sure the meals are healthful and well-balanced.

Dietary Guidelines and Nutrients for Mastiff

If you have a Mastiff, you need to be aware of his nutritional requirements as a puppy in order to promote his healthy development.

And it's not just about picking the right puppy food.

It's about knowing what kinds of foods he should eat as part of a healthy, well-balanced diet.

Your dog requires sufficient nutrition in order to develop into a healthy adult free of major diseases and with proper physiological function.

Mastiff puppies require 25-27 percent protein and 12-15 percent fat, which differs from adults due to the rapid muscle growth that happens throughout their formative years.

A Mastiff should be fed 21-25 percent protein and 8-10 percent fat as a mature.

If an adult Mastiff is given more than 21- 25% protein, illnesses such as hepatic and renal failure can develop.

Mastiffs, like other dogs, require a balanced diet of protein, minerals, amino acids, lipids, and fatty acids in order to maintain a healthy weight and bone structure.

Mastiff diets are primarily meat-based, with both protein and fat coming from human-grade sources.

Carbohydrates should make up the third half of a Mastiff's diet, as they will provide him with the energy and calories he needs.

If you're going to feed your Mastiff dog food, make sure it has at least three animal proteins in it.

These components should come first on the ingredient list, and they should ideally come from beef, fish, lamb, or chicken.

Simultaneously, you should stay away from any store-bought goods that contain artificial colors or preservatives.

While fibers are necessary for your dog's digestive system to function properly, a meal that contains more than 5% of them can be harmful to their health.

Furthermore, many owners prefer not to offer grain-based fibers to their Mastiffs because these elements might induce allergic reactions in susceptible breeds.

Introduce starchy vegetables, such as peas, as an alternative fiber source that does not contain grains.

Finally, making sure your Mastiff has enough Omega-3 sources is critical.

Whether you feed your dog salmon or simply give him Omega-3 pills, such chemicals can help maintain the health of his coat and skin.

How Much Do Mastiff Puppies Grow Each Week? 

You may expect a lot of variation in mastiff puppy growth from one litter to the next.

This is due to the fact that development is determined by a variety of circumstances, and no two puppies develop at the same rate.

Physical activity, metabolism, and food are all factors that influence the growth of mastiff puppies.

This makes determining the amounts that grow each week challenge. However, a safe estimate is 2 pounds every week.

Switching From Mastiff Puppy Food To Adult Food 

It will eventually be time to transition your Mastiff from puppy to adult food.

Mastiff dogs have a lot more growing to accomplish because they are huge breeds.

Mastiff dogs are considered fully developed when they reach the age of 24 months.

Make sure the transition is painless since rapid changes might cause your dog to have an upset stomach and a variety of other problems.

Introduce some grownup food at a specific eating time during the day until the transition is complete.

The idea is to keep your Mastiff puppy as slender and fit as possible while avoiding diseases that are known to harm the breed.

What If My Mastiff Puppy Won’t Eat?

You should treat your Mastiff puppy's refusal to eat as a severe problem because this is how he gets his nutrients.

Before you go to the veterinarian, make sure it's nothing serious.

Check his food to make sure it's all right, and give him a day to see if it goes away.

When dogs are overfed, they will refuse to eat.

Keep an eye on your dog to determine whether you're overfeeding him, but if the problem persists, consult your veterinarian.

Should You Feed A Mastiff Puppy Supplements?

This could be very beneficial to your Mastiff, especially if he isn't getting enough nutrients from his meals.

Your mastiff will need a lot of water as a huge breed dog.

However, keep an eye out for bloating and avoid giving him too much water all at once.

Allow him to drink as much water as he wants, but no more than 3 1/2 cups at a time.

Because of his larger size, he should be able to consume more water than a typical dog.

What Kind And How Much Daily Exercise Does A Mastiff Puppy Require?

Extensive road work (running) type exercises should not be done until after the age of 18 months, due to the rapid growth of these puppies.

Joints and growing bones are particularly vulnerable to injury.

Allowing the dog to jump off elevated areas (such as porches, decks, and pickup truck beds) or walk up more than three steps is not recommended.

Jumping off a 2-3 foot high deck, a 10-week-old large breed puppy broke both front legs.

They may also suffer injury to their shoulder joints.

To avoid joint injuries, puppies should not be allowed to play or spend significant time on slippery surfaces (i.e. tile or linoleum floors).

Allowing the Mastiff puppy to become overweight puts stress on its growth plates, which can lead to broken bones.

Similarly, do not leave your puppy in a crate for long periods of time.

Exercising insufficiently is just as harmful as exercising excessively.

To carry its adult weight and be a strong, healthy, active dog, your puppy will need to exercise to develop proper muscle tone and bone structure.

Allowing children to pull on the legs, jump on, or lie on your puppy, despite its size, is not a good idea.

It's possible that you'll sustain a long-term injury.

Always keep an eye on your children (both young and old) and teach them how to interact properly with your puppy.

Tease, hit, and injure your puppy, and he or she will develop an antisocial personality.

All members of a puppy's family should shower it with love and positive reinforcement.

Because Mastiffs are enormous, fast-growing dogs with sluggish joint development, their exercise levels must be strictly regulated until they reach the age of 18 months to avoid injury.

You must keep an eye on your dog's activity level to avoid over-exertion while ensuring that he gets enough exercise.

This usually accomplished through activities such as walking or playing with toys.

Stop when the dog exhibits indications of exhaustion; young puppies should not be taken on extended walks unless you can carry them home!

Creating A Consistent Feeding Schedule for Mastiff

The feeding plan for your Mastiff can vary based on your preferences.

The majority of dog owners like to feed their pets twice a day, once in the morning and once in the evening.

This method ensures that your dog has enough energy to keep him comfortable throughout the day.

Feeding your Mastiffs at different times depends on when you are available to take your dog out to relieve himself.

In any case, your Mastiff should be fed at least twice a day.

A single large meal can encourage your dog to eat more quickly and aggressively.

Aside from the digestive issues that this practice can create, eating only one meal per day can lead to increased aggressive behavior.

Remember that a dog's stomach will be empty in approximately 7 hours. So even if you only feed your Mastiff once, he'll remain hungry for the rest of the day!

Mastiff Background Information


The enormous Mastiff is a member of a canine family that dates back to the dawn of humanity.

The Mastiff is a large, heavy-boned dog with incredible power and courage.

He is placid and dignified, but also a fierce protector of the people he loves.

A face-to-face meeting with these black-masked giants can be disconcerting for the inexperienced.

A full-grown guy can outweigh a male who stands at least 30 inches tall at the shoulder.

A short double coat of fawn, apricot, or brindle stripes covers the rectangular body, which is deep and strongly muscled.

A furrowed forehead underlines an alert, compassionate face on the large and powerful head. Mastiffs are patient, loyal guardians who respond well to moderate instruction.

Mastiffs are fiercely loyal to their families, and their instinctive fear of outsiders necessitates early socialization and training.

Mastiffs are wonderful pets, but getting a robust giant-breed dog is a significant commitment.
