Taking care of your pet is understanding how much your animal should eat and how often.

All you need to know is here in this article, which discusses how much diet a Mastiff needs and how often it should be fed.

How Much Food Should A Mastiff Eat? 

Fully-grown Mastiffs should eat between 6 and 10 cups of dry food everyday depending on the dog’s appetite and personality.

Older pets will require less food, but growing puppies need to be fed a lot to grow properly.

As a Mastiff puppy grows, its nutritional needs and requirements change just as fast. For the first year or two of its growth phase, a Mastiff will require a lot of food to help it grow, but once the pup has grown, that amount is reduced.

Older Mastiffs need around 2.6 lbs of food every day, which is scheduled into two meals. They do not have high protein requirements, unlike the puppies.

Puppies are growing rapidly and need more protein than older dogs because they need more energy to grow.

So, your puppy should be fed more these days in order to meet the increased demands for proteins and calories.

Mastiff breeds have different diets, which may depend on their age, gender, personality and what type of food they eat.

To maintain a healthy weight and good development of their bones, the food offered to a Mastiff should be rich in minerals, protein, fat, vitamins and other necessary nutrients.

Mastiff does not require many calories. The majority of their diet is meat-based food, so we are confident that human grade sources of meat will be sufficient.

The following factors are important to consider when you pick food for your dog:

  • Make sure it’s a complete meal (i.e. has all the nutrients your dog needs).
  • Avoid any food that contains artificial coloring or preservative on the ingredients list
  • Fibers are essential for the proper functioning of your dog’s digestive system, but too much fiber could be bad for him.

Your Mastiff might feel bloated and exhibit other symptoms if he eats fibrous food that is too rich.

Below are some specifications for your mastiff, including its age, weight and any other necessary details.

2–3-week-old Mastiff:

If a 2-3 week old Mastiff is not taught all the basic commands, it will later become difficult to bring them on a walk outside.

A 2-3 week old Mastiff puppy should have at least 3 to 4 meals per day. Each meal should be around three-and-a-half ounces of food: two to three cups should be enough.

Maintaining the right weight is important for Mastiff puppies. They need to have a weight between 13-16 pounds with a minimum 450 daily calorie intake.

To promote faster growth and overall health, feed your puppy food that is high in protein and other nutrients.

4-5-week-old Mastiff:

Newborn mastiff puppies should have 3-4 meals per day, each meal weighing around 3.5 oz. One or two cups of dog food should be sufficient for the entire day.

6-7 week old Mastiff:

When they’re 6-7 weeks old, Mastiff puppies need to eat 3-4 meals per day each consisting of 3.5 oz: you’ll need about 2-3 cups of dog food for that.

Are You Overfeeding Your Mastiff Or Not Feeding Enough?

Overfeeding or under-feeding your Mastiff can lead to serious health risks. Do you know how much you should be feeding your dog?

Your dog’s health is one of your top priorities, so it’s essential to know their health status and identify which diet they need.

Dogs can either be overweight or underweight, and there are several symptoms to look out for.

If a Mastiff has an enlarged waist and you cannot feel its ribs, hips, or spine manually then it is overweight, then it. Overfed Mastiffs are easy to spot if their waists are swollen.

This sentence outlines how you can tell if your dog is overfed. If you put a lot of pressure near the ribs and don’t feel them, it probably means that your dog is carrying too much weight.

One sign that your Mastiff is overfed is if they’re having bowel issues, indigestion and discomfort. Overfeeding puts too much stress on their digestive system which can lead to irregularity.

When a dog is underfed they will be more likely to suffer from frequent flatulence and bouts of gas. This will result in an unpleasant smell which can be off-putting to others.

How Frequently To Feed Your Mastiff?

Feeding frequency for Mastiff puppies changes often, and as they grow their nutritional needs change accordingly every week.

You should feed your puppies more often during the day, since they will spend a lot of time playing or running outside. This burns up a lot of their energy and requires a proper diet to replenish them.

For puppies aged 3 weeks to 4 months, it is advisable to feed them foods that are highly nutritious to combined with dog food.

For the appropriate age range (5 to 6 months to 12+ months) you should feed your dogs regular dog food 2-3 times a day.

Recommended Feeding Time

Mastiffs have no specific feeding time, but are fed at least twice a day – once at dawn and once after sunset.

Additional meals can be fed throughout the day to correspond with your dog’s activities and diet requirements.

Keep your dog’s stomach empty for no more than eight hours at a time, or it will trigger hyperacidity and starvation.

Final Thoughts

In general, Mastiffs need to consume six to ten cups of dry food per day when they’re fully grown, although the exact number will depend on things like your dog’s appetite, preferences, and even its nature. 

Younger dogs will require a lot more food to grow and develop healthily, but older ones don’t need as much any more.
