Neapolitan Mastiff Puppy Food: When and What to Feed Them

Generally speaking, puppies of any breed should be fed food specially formulated to meet the nutritional needs of growing pups. Merrick Puppy (from is an excellent puppy food that will give your pooch all the nutrients he needs. 

But with large breed puppies like the Neapolitan Mastiff, you’ll want to take it a step further. Look for puppy foods made for large breed dogs. These formulas typically have extra nutrients and supplements that larger dogs need for healthy development. 

Neos can experience multiple problems as they age, including bone and joint pain and damage, so they need nutrients such as glucosamine and chondroitin, which help with healthy bones and joints. 

Diamond Naturals (from is specifically for large breed puppies. It includes glucosamine and chondroitin, but it also has DHA for healthy brain and eye development. 

The younger a puppy is, the more food they will need to consume to be healthy. The amount will vary based on your pet’s individual needs and the brand of food you use. Each manufacturer has different guidelines. Neapolitan Mastiff puppy feeding guide

Remember, the feeding amounts below are just an approximation. Pet owners should always talk to their vet and consult their pet foods feeding chart to determine the exact amount their dogs should be fed.

Feeding Times for Neapolitan Mastiff Puppies

Some pet parents give their Neos two meals a day after one year, but they do so by dividing the daily amount of food into two portions. A full-grown Neapolitan Mastiff can and usually will consume up to seven cups (56 ounces or 1,750 ml) of high-quality dog food a day. 

Set a feeding schedule for your puppy that you stick to every day. Feed your Neo in the same location and at the same time. During feeding time, leave your pet’s food set out for up to twenty minutes. Remove what they don’t finish. 

Many parents like to feed their Mastinos at the same time that they eat their meals. Usually, at around 7 a.m., noon, and 5 p.m., but don’t feed your pooch after five, so you reduce the chances of potty accidents.

Pro-tip: Neapolitan Mastiff anxiety, aggression, destructive chewing, jumping up, fearfulness, and other behaviors can be controlled with the right training program.

When to Stop Feeding Your Mastiff Puppy Food

Because Neapolitan Mastiffs mature slower than small breed puppies, you’ll need to keep your pup on puppy food for a longer time. Most Neos won’t transition from puppy food to adult dog food until 18 to 24 months.

Neapolitan Mastiffs should be switched to adult dog food once they’ve reached adulthood, which varies individually. Your pet’s behavior is a good indication that they have fully matured.  

Once in adulthood, your Masstino will stop acting rambunctious and will start listening better. They’ll also grow slower or stop growing altogether.

So when do Mastiffs stop growing? Our article here will explain. 

Make the Transition Slowly

Once you’ve decided it’s time to switch your Neo from puppy food to adult food, you’ll need to set up a routine that allows you to change slowly over five to seven days. 

Doing an abrupt switch from one food to another can cause your puppy to experience digestive problems, such as tummy aches, diarrhea, and vomiting. 

Follow this rough schedule on how to transition your pet from puppy food to dog food or between different brands. 

Days 1 - 2: 25% new food 75% old food
Days 3 - 4: 50% new food 50% old food
Days 5 - 6: 75% new food 25% old food
Day 7: 100% new food - no old food

Best Dog Food for Neapolitan Mastiff Puppy

When picking a dog food for your Neapolitan Mastiff puppy, there are specific criteria your large breed pooch will need.

Puppies need higher protein than adult dogs. Protein provides your pet with energy and helps build healthy muscles. However, you don’t want to give your puppy too much protein, as that can cause a problem with calcium and phosphorus imbalance. 

Look for brands that are lower in fat and calories. Giving your puppy a brand with too many calories and fat can cause him to grow too quickly, leading to potential health problems like hip dysplasia and arthritis. 

Read the label of every dog food to find out crucial information about the nutritional needs it offers. And make sure the food you pick meets the AAFCO guidelines, which ensures your pet will get the proper nutrition. 

Your Neo puppy will need at least 30% protein, 1.5% calcium, and 9% fat. 

3 Of The Best Wet Mastiff Puppy Foods 

Your puppy should be weaned from his mother by eight weeks old. By six weeks of age, she should be eating wet dog food. Some pet parents mix warm water with dry kibble.

But other parents prefer to use wet dog food, often found in cans. However, once your Neo gets teeth, he needs dry food, as wet food isn’t good for your pet’s teeth. 

Therefore, you should switch your puppy from wet puppy food to dry puppy kibble by eight weeks.

3 Of The Best Dry Mastiff Puppy Foods 

Once your puppy is eight weeks old, it’s time to switch them to dry kibble. It’s best to use puppy food, not just because it provides the proper nutrition, but also because of the size.
