Newfoundlands, often known as Newfies or Newfs, are large working dogs renowned for their huge size and endearing demeanor. Newfies were originally bred as water rescue dogs and saved many men from drowning in the chilly North Atlantic waters.

If you're the fortunate owner of one of these gentle giants, you may be wondering how big Newfoundland dogs grow and when they stop growing. Our Newfoundland growth chart can provide you with an estimate of your puppy's weight at various developmental stages.

When Do Newfoundland Stop Growing?

Before we begin, it's important to remember that Newfoundlands are not like other dogs. They continue to grow long after the majority of other breeds have attained adult height and weight.

So, when does Newfoundland stop growing? Generally, a Newfie is completely matured at the age of two.

What you need to know is that if your dog does not grow in height after reaching adulthood but does gain weight, you must ensure that the weight gain is not due to obesity.

What is the Standard Newfoundland Size

Adult male Newfoundlands weigh an average of 130-150 pounds, according to the AKC and the Newfoundland Club of America.

Female adult Newfies weigh between 100 and 120 pounds.

It's critical to note that this is general guidance and that the dog's body structure should also be considered.

A smaller-framed Newfie should weigh less than a larger-framed Newfie.

A healthy adult male Newfie who weighs less than 120 pounds is absolutely acceptable.

Newfoundland Growth Chart – What To Expect
Newfoundland Weight Chart by Age

Newfoundland Weight  1-2 weeks

There isn't much for you to do at the moment except take care of Mommy Newfie. Her health dictates how effectively she can care for her pups, and she will want additional food to maintain her strength.

The pups, on the other hand, are completely reliant on mum, and with their eyes and ears closed, they are not receiving input from the outer world at the moment.

If something does go wrong with Mom's dog, you will require immediate assistance from a veterinarian, since you will need to bottle feed the puppies at frequent intervals using a specific puppy formula.

Newfoundland Weight 3-12 weeks

While the mom dog will instinctively know when to begin weaning her pups, giving an alternate food source will assist her in initiating the process.

She'll spend less time with her pups, who are now fully aware of their surroundings. Allow some puppy formula with a small amount of solid food (high-quality puppy kibble is ideal) to soak in and observe what happens.

Reduce the puppy formula and increase the number of solids in the following weeks. Your puppies will be sufficiently weaned by the 8-week point, but it is best to wait until the 10- to 12-week period.

Newfoundland Weight 4-6months

Each Newfoundland puppy will develop at his or her own rate. However, a six-month-old Newfoundland puppy should stand between 22 and 24 inches tall.

At six months of age, male Newfoundlands weigh between 73 and 87 pounds on average. Six-month-old female Newfoundlands weigh slightly less than six-month-old male Newfoundlands, weighing between 59 and 72 pounds.

Newfoundland Adult Weight 

The advice we've given you on the management of your puppy's skeletal structure is applicable until he or she reaches the age of around 24 months.

Prior to that, it is unwise to think of your pup as an adult, even if the size may trick you.

Gentle training should have been continuing since your Newfoundland arrived, and because these dogs are incredibly intelligent and genuinely want to make you happy, they are quite open to it. Maintain your excellent work.

Being overweight poses a significant health risk for big breeds, so keep an eye on your Newfie's weight and strive to reach the sweet spot when he is neither too fat nor too lean. That goalpost will continue to move forward until your dog reaches the age of 18 to 24 months.

What is the Full Grown Newfoundland Weight?

Male Newfoundland dogs should weigh between 130 and 150 pounds, while females should weigh between 100 and 120 pounds, according to the American Kennel Club's (AKC) official breed standards.

Male Newfs should also be slightly taller than female Newfs, standing about 28 inches tall. Male and female Newfies will have a strong bone structure and carry themselves with dignity.

How To Weigh Your Newfoundland Puppy?

If you want to maintain track of your Newfoundland's weight, you must first learn how to weigh him properly.

To begin, you should be able to weigh your Newfoundland at home if he is a puppy or if you are just large enough to hold him. This can be accomplished with a standard bathroom scale.

To begin, weigh yourself and record the result. Then, while standing on the scale, pick up your dog and hold him. The difference in weights represents your dog's weight.

If your dog is too huge to carry, you can either invest in a dog scale, which can cost upwards of $100, or contact your veterinarian. The majority of veterinarian offices will enable you to use their scale.

Unless there is a health problem, you can weigh an adult Newfoundland once every six months. Once a week is sufficient for a puppy to ensure he is growing normally.

What Is A Newfoundland’s Neck Size?

To determine the neck size of your dog, use a soft and flexible tape measure to determine the neck size of your dog where her collar naturally falls. Then, put two fingers between your dog's neck and the tape measure to ensure that the dog collar fits snugly but comfortably. Newfoundland's average neck circumference is between 23 and 27 inches.

How Big Do Newfoundlands Get?

Newfoundland dogs are considered to be of the big breed. When they reach full size and weight, they are 2-3 inches (5-8 cm) taller and 20-30 pounds heavier than a Great Pyrenees dog (9-14 kg).

Their gigantic physique is even more apparent when compared to a Bernese Mountain Dog, another giant dog species.

Female Newfoundlands are approximately 30 pounds (14 kilograms) heavier and 2-3 inches (5-8 cm) taller than male Newfoundlands.

Men can weigh between 30 and 50 pounds (14 and 23 kg) more and stand 3-5 inches (8-13 cm) higher than Bernese males.

Factors That Affect Newfoundland Puppy Growth 

Genetics

As previously said, Newfoundlands are all large dogs, albeit some are larger than others. It's all about their genetic composition.

By examining the dam and sire, you can get a sense of what to expect from your puppy's genes. If both parents are large examples for the breed, there is a strong chance your pup will be as well.

However, grandparents' genes also play a role, and your pup's profile may differ from that of either parent. Additionally, there are certain “late bloomer” Newfies that appear to begin growing far later than their siblings.

Diet & Nutrition

Genetic potential is exactly what it sounds like. While genes may indicate the size at which your pet should grow, whether those genes express themselves fully is dependent on a number of circumstances.

Nutrition is one of the most critical. A puppy that is malnourished will not develop its full genetic potential. Consider how World War II rationing resulted in a whole generation being shorter than their children or grandkids who did not encounter food shortages.

Dogs are no exception. They will not develop as large as they should without proper nutrients. Puppyhood is a critical stage of development. Utilize our Newfoundland size chart as a guide for achieving the proper balance.

Physical Activity & Health

Physical activity and health are also critical for the development of a puppy. Allow plenty of space for your pup to play, but avoid forcing it to go on lengthy or difficult walks, even if you find its energy a little too much for you to handle.

Keep your puppy away from hard or slippery surfaces, which can have a negative effect on bone and joint health later in life. Jumping games are likewise not encouraged throughout puppyhood. Keep an eye on your puppy's health.

Appetite loss, listlessness, constipation, or diarrhea are not desirable symptoms. A healthy maturity is a contingent upon a healthy puppyhood. Consult your veterinarian if you have any concerns.

Will Neutering/Spaying Affect the Growth of My Newfoundland?

The majority of puppy owners will plan to have their dogs spayed or neutered during the first year. If you have no intention of reproducing the dog or showing it, there is no reason not to have the procedure performed.

Sterilization is a routine and safe procedure that prevents unwanted pregnancies and difficulties. Additionally, it will keep your dog from rushing away in search of a partner. However, the method introduces a growing risk that did not exist previously.

In recent years, it has been demonstrated that when large breed dogs, like Newfoundland, undergo surgery at an early age, their joints do not grow properly. It is advisable to wait until they have reached the point of no return.

How do I ensure the health of my Newfoundland?

Newfoundlands, like purebred canines, are predisposed to genetic health concerns. While this is sad to consider as loving Newfie parents, there are some things we can do today to ensure our Newfie's health and happiness. The most critical aspect is routine veterinary care for our Newfoundlands.

Newfoundlands are predisposed to skeletal abnormalities including hip dysplasia, wobbler syndrome, cataracts, and aortic stenosis. Wobbler syndrome is more prevalent in large and enormous dog breeds, such as Newfoundland, and can result in an unsteady gait in mild cases and paralysis in severe cases. In the majority of instances, surgery is required to alleviate pressure on the spinal cord, with a generally satisfactory prognosis thereafter.

Common Questions about Newfoundland

At What Age Is A Newfoundland Fully Grown?

Newfoundlands should be completely developed by the time they reach the age of two. After their second year, they reach their full adult size. Any further weight gain is conceivable, but it is not desirable and should be avoided or managed.

Interestingly, this is also the time when Newfoundland dogs reach their peak for mating.

That is a lengthy period of time when compared to the majority of other breeds. Full-grown Newfoundlanders weigh an average of 130-150 (59-68 kg) pounds and stand an average of 26 to 28 inches tall (66-71 cm).

Of course, male canines are slightly larger than female dogs. Females should be approximately 26 inches (66 cm) tall and weigh between 100 and 120 pounds (45-54 kg).

One of the primary reasons people choose a Newfoundlander is for their enormous size – the larger, the better. Individual Newfoundlanders can weigh up to 200 pounds (91 kg), but this is extremely rare.

The largest Newfoundlander has a body weight of 260 (118 kg) pounds and a height of 6 feet (183 cm) (nose to tail). However, the weight of your dog should never be the primary concern; monitoring his health is far more critical.

How Long Are Newfoundlands Pregnant?

This is when they breed with males to produce offspring. This stage typically lasts two to three weeks. After conception, the gestation period is typically between 58 and 68 days.

How Many Puppies Do Newfoundlands Have?

The average Newfoundland litter size is between eight to ten puppies but can range between two and fifteen.

What Is The Life Expectancy Of Newfoundlands?

The Newfoundland, with an average lifespan of 8 to 10 years, is prone to serious health problems such as gastric torsion, Subaortic Stenosis (SAS), cystinuria, canine hip dysplasia (CHD), epilepsy, and elbow dysplasia, as well as minor problems such as von Willebrand's Disease (vWD), cataract, and Osteochondrosis Dissecans.

How Much Does It Cost To Own A Newfoundland?

A Newfoundland comes with a number of expenses that a prospective owner should budget for. This includes veterinarian expenditures, training charges, food-related costs, supplies, and grooming, among other things. To assist families with financial planning when they welcome Newfoundland into their home, we've created a comprehensive cost calculator.

A Newfoundland puppy will typically cost between $600 and $2,000, with an average of $1,200. The first year's expenses are approximately $3,930 and will decrease to approximately $2,305 per year (or $192 per month) thereafter. The average cost of having a Newfoundland is $24,675 during the dog's lifetime.

These estimates include necessary expenses such as supplies, training, medical bills, food, treats, grooming, license, and microchip. Furthermore, supplementary fees such as insurance and dog walking are not included. If you spay or neuter your dog, purchase pet insurance, board your dog for one week each year, and hire a dog walker for 50 weeks of the year, your total cost of ownership is likely to increase to between $53,285 and $117,985.

How To Help Your Newfoundland Lose Weight If He Is Overweight 

As with humans, exercise is critical for your overweight dog's health. Increased movement helps your dog burn off excess energy (and calories consumed). Avoid panic! Exercising your pet does not have to include marathons or lengthy hikes. Regular walks and the opportunity to run and play safely off-leash. 

Even creating a stimulating indoor environment that encourages your dog to exercise on a regular basis can help. Bear in mind that different breeds require varying amounts of exercise, so visit your veterinarian, breeder, or your dog's breed standard for recommendations on recommended activity levels.

Distinguish Begging from Hunger

Begging is not necessarily motivated by a desire for more food; it is also used to gain attention. (And, by rewarding the behavior, you reinforce and encourage it to continue.) If your dog begs, do not automatically assume he is hungry. Trust your instincts and keep track of the date and time of your last meal. 

If your dog is prone to begging and you are prone to succumb to those puppy dog eyes, choose a high-protein meal with a fiber blend to help control your dog's hunger and voluntary food consumption. In this manner, you may feed your dog with the assurance that he will feel fuller and content for a longer period of time.

Restriction on treats and table scraps

Even when our dogs are not begging, many of us provide an excessive amount of treats and table scraps. Dogs are not required to share our food! Consider treats and scraps for your pet in the same way that you would candy for children to help you keep them in check. If you're going to utilize snacks for training, choose low-calorie, low-fat ones and keep the portions small. 

As an alternative, keep in mind that clickers are excellent for reinforcement… and they have no calories! After all, a few extra pounds can make a significant impact in the lives of dogs, which are significantly smaller than humans. (Even the colossal breeds!) Therefore, focus on a balanced diet and resist the temptation to “reward” them with extra.

Customize Your Dog's Diet

Not all weight-loss foods are created equal, which is why it's critical to match your dog's nutrition plan to their unique needs. Choose a brand that caters to your dog's unique needs, whether they be weight control, dietary sensitivities, or illnesses.
