When Do Newfoundlands Stop Growing?

The Newfoundland is a giant dog breed, hence it takes longer for them to mature than smaller dogs. It takes most Newfoundlands about two years to attain the full weight and height of an adult dog.

The Newfoundland, like other big and gigantic breeds, matures most rapidly during the first six months of life.

When Do Newfoundlands Stop Growing

Newfoundlands are already enormous dogs at that age, and they’ll keep growing until they turn two.

Newfoundlands, like most other breeds of dog, tend to attain their full adult height before their full adult weight.

Although your puppy’s height may stop increasing after their first birthday, their weight and girth will continue to increase.

Newfoundland Puppy Development Stages

Newfoundland Puppy Development

Birth – 2 Weeks

As of right now, your main responsibility is to tend to the mother Newfie. She needs more calories since her strength dictates how effectively she can nourish her puppies.

The puppies are absolutely reliant on her, and they aren’t getting any information from the outside just yet since their ears and eyes are closed.

3 Weeks – 12 Weeks

A new food source would make it simpler for mom dog to start weaning her puppies at the right time.  Her puppies are now fully awake and she will spend less time with them.

Just see what happens if you leave out some puppy formula that has been soaked with a little amount of solid food (good quality puppy kibble works wonderfully).

The puppy formula should be gradually decreased and more foods added during the following weeks.

Your pups will be weaned enough to go home around the 8-week mark, but it’s best to wait until they’re 10 to 12 weeks old.

4 Months – 9 Months

See how your puppy compares by using our Newfoundland puppy weight chart as a starting point.

They’ve grown considerably larger than that by now and show no signs of stopping! In addition, they will be quite playful. Young Newfoundland dogs have a soft side and a strong desire to please.

10 Months – 18 Months

At this stage, you’re dealing with a jubilant behemoth of epic proportions. But don’t let it deceive you. And it certainly hasn’t slowed down in its expansion thus far!

Although the growth curve may be flattening, which may come as a comfort to you, your dog will continue to expand in size.

An essential fact to keep in mind is that your puppy’s “growth plates” have not yet fused, meaning that his or her bones are still developing.

It’s a huge puppy, but too much exercise too soon might stunt its growth. You shouldn’t go for lengthy walks, especially on concrete or asphalt.

A small bit of careful walking on the lead can assist the little one get used to walking with you, but play in a large yard is better.

You won’t be sprinting anywhere together. And you’ll only be able to go for a stroll for up to five minutes every day for every month your dog is old. No, you shouldn’t go for a jog every single day.


Your puppy’s skeleton is still developing until roughly 24 months of age, so follow our guidelines for bone and joint care.

Prior to that time, despite appearances to the contrary, it is not safe to treat your puppy as if it were an adult.

Your Newfoundland should have been receiving gentle instruction since he or she entered your house; as a breed, they are very smart and eager to please their owners. Continue your excellent job.

How Big Do Newfoundlands Get?

Examine the paws of your Newfoundland. As a traditional sign of continued growth, a puppy’s paws will seem disproportionately large to the rest of its body and legs.

In the end, it’s best to get in touch with the breeder you bought your Newf from to get an even more accurate idea of how big your dog will become when fully grown.

Your Newfoundland’s breeder should have a better idea of the dog’s expected adult size based on the history of the breed.

Newfoundland Development

You probably have an idea of how large a mature Newfoundland can become. These dogs are rather big.

A Newfoundland Growth Chart is a good starting point for anybody curious about their puppy’s potential adult size, but it shouldn’t be your only source of information.

The size of your puppy’s parents is the best indicator of the final size of your dog. If you have doubts about your dog’s pedigree, a DNA test is another alternative.

Male Vs Female Newfoundland Size Chart

The Newfoundland is a big dog breed. Upon reaching maturity, they tower above other large canines by a height of approximately 2-3 inches and a weight of 20-30 pounds more (9-14 kg).

About 30 percent more weight (14 kilograms) and 2-3 inches (5-8 centimeters) in height characterize a female Newfoundland.

Males may be 3–5 inches (8–13 cm) heavier and 1–2 inches (2.5–5 cm) taller than their counterparts.

Will Neutering/Spaying My Newfoundland Affect His Growth?

Spaying or neutering is a common practice among dog owners, and most people aim to do so within the first year. These are giant breed dogs so it is better to wait a while longer.

Common, safe, and effective, sterilization surgery eliminates the possibility of unplanned pregnancies and their associated health risks.

Your dog will be less likely to go off in search of a mate if you do this. However, the process now includes a new source of worry about expansion.

It has been more clear in recent years that early surgical intervention may negatively affect the joint development of big breed dogs like Newfoundlands.

The optimum time to do this is after they have finished developing. At around 18 months would be safe.

Labrador Vs Newfoundland Size

Despite their similarities in size, the Labrador Retriever and Newfoundland are two distinct dog breeds.

The average Labrador Retriever weighs between 55–75 pounds and is between 21.5-24.5 inches at the shoulder in height, whereas the average Newfoundland is between 100–150 pounds and 26–28 inches in height.

To most people’s eyes, the Newfoundland is a significantly bigger dog than the Labrador Retriever.

It should be kept in mind, however, that even within a given breed, individual dogs may exhibit a wide range of sizes.

The Newfoundland is a working breed distinguished by its strength, stamina, and swimming abilities, whereas the Labrador Retriever is a hunting breed renowned for its intelligence, trainability, and friendly demeanor.

Factors That Affect Newfoundland Growth 

Newfoundland Growth

Genetics & Gender

While all Newfoundlands are large, some are much larger than others. It’s all in the genes, really. An examination of the puppy’s parents might give you an idea of the breed’s genetic makeup.

It’s likely that your puppy will share their proportionate size if both parents are large for the breed.

Your puppy may look nothing like either of its parents, however, because of the influence of grandparental DNA. Some Newfs, known as “late bloomers,” start their fast growth after their siblings.


Literally what it says it is: genetic potential. The size of your pet might be predetermined by its genes, but whether or not those genes are fully expressed relies on a number of circumstances.

The importance of a healthy diet cannot be overstated. A puppy that isn’t fed well will never live up to its complete genetic potential.

Consider the fact that due to food restriction during World War II, a whole generation of individuals is shorter than their grandchildren or children who did not experience such shortages.

Dogs are the same. They won’t develop normally if they don’t have enough to eat.

An important period occurs throughout a puppy’s early life. Take a look at our Newfoundland size chart to help you find the proper proportions.

Physical Activity & Health

Puppies also benefit greatly from regular play and good nutrition.

Your puppy needs plenty of room to run about and play, but you shouldn’t subject it to lengthy, exhausting walks just because its energy is getting to be too much for you.

You should avoid exposing your dog to rough or slippery surfaces since they might damage its developing skeleton and joints.

The same goes for jumping-based games while the puppy is still young. Keep an eye on your puppy’s health.

Loss of appetite, lethargy, bowel problems, or both, are all warning indicators that something is wrong.

A hale and hearty puppy is essential for a robust adult. Talk to your vet if you’re worried about your pet’s health.

How Much To Feed A Growing Newfoundland Puppy?

Age, size, and activity level determine how much food a Newfoundland puppy requires. Your vet should decide your puppy’s nutrition.

Newfoundland puppies should be given three to four little meals each day instead of one or two big ones. This will avoid bloating and preserve growth.

They should consume 4% of their body weight daily from 8-12 weeks to 3% at 6-12 months.

To promote healthy growth, check your puppy’s weight and feed them properly. Hip dysplasia may affect fast-growing puppies.

High-quality puppy food for big breeds with their specialized nutritional demands is also essential. Protein, fat, plus minerals and vitamins will help them flourish. As a big breed, Newfoundlands may easily become obese if overfed.

How To Tell If Your Newfoundland Is Underweight Or Overweight? 

Talk to your doctor, a dog nutritionist, or do enough study before taking this dangerous step.

Puppy growth benefits from exercise. It will prevent the pup from growing fat and developing hip or knee dysplasia. Exercise builds muscle so make sure your dogs get the right amount of exercise.

Underweight puppies may have weak muscles from lack of activity. Daily dog sports will help your puppy build muscle.

Consider the dog’s weight and body structure.  If a pup’s bodily condition is good, he may be underweight yet healthy.

The dog’s ribs should be felt beneath your palms, not seen although Newfie’s are fluffy so it is difficult to see.  When bathing Newfoundlands, you can see their body outlines since they have so much fur.

Do Newfoundland Experience Growing Pain?

Like puppies of other big breeds, Newfoundland pups may feel some discomfort as they develop.

His bones and joints may experience pain and discomfort as they develop rapidly.

Growing pains in Newfoundland pups may cause them to become stiff, and lose interest in normal puppy activities like running and playing. When the puppy is more active, these symptoms often subside.

If you think your Newfoundland puppy is suffering growing pains, you should take him to the doctor to rule out any medical issues.

Your doctor may offer bone and joint health supplements in addition to a growth-stage-appropriate food and activity regimen for your puppy.

Keep an eye on your puppy’s activity level, as too much exercise or rough play may be harmful to their growing bones and joints.

How To Help Your Newfoundland Lose Weight If He Is Overweight?

Though it may seem simple, dogs need more than just free playtime to be healthy and happy. You may take your dog for walks, treks, games of fetch, and even the pool. I was wondering what your dog’s diet consisted of.

Overfeeding your dog food with unnecessary fillers will not aid in his weight loss. Choose foods that are rich in protein and low in carbohydrates. Remove the treats that tempt them ad cause them to gain weight.

How To Properly Weight My Newfoundland?

You may be perplexed by the Newfoundland dog weight and development charts, wondering how on earth you’ll ever be able to determine an accurate weight or height for your pet.

Many alternative strategies exist for helping your dog reach a healthy weight.

When a Newfoundland is a puppy, it’s the simplest. Then, all you have to do is weigh yourself on a home scale.

Of course, Newfoundlands quickly outgrow the ability to carry them in one’s arms.

At that point, you have the option of taking your dog to the doctor for a professional weight check or buying a big dog scale for at-home use.

Newfoundland Genetics And Common Health Problems

The breed’s biggest drawback is the same thing that draws us to Newfoundlands and has us looking for a growth chart to track the development of these infant giants: their enormous size.

Canine hip dysplasia (CHD) is a prevalent condition in big dog breeds and should be taken into consideration when selecting a breeder.

A reputable breeder will do thorough health screenings on the breeding stock, including the father and mother, and any offspring.

In addition, large-breed dogs are prone to developing canine heart disease (CHD) and arthritis at an early age, all of which are preventable with the right kind of treatment.

Also like other gigantic breeds, Newfs are prone to stomach torsion and ligament ruptures.

Cataracts are frequent but may be readily (though costly) treated. It’s also been linked to epilepsy and heart disease.

Get your veterinarian’s opinion on whether or not your prospective breeder performs health tests on the parents of the puppy you’re considering.

Final Words

In conclusion, the Newfoundland is a very large and robust breed. Your Newfoundland puppy will grow into a healthy and well-proportioned adult dog if you give it the attention and food it needs.

Making sure pups are developing normally and are on pace to realize their full potential requires keeping an eye on their height and weight.

And most all, remember to have a good time and take pleasure in seeing your fuzzy pal grow into a kindly giant!
