Newfoundland Size Predictions: How Big Do Newfoundlands Get?
As a giant breed, Newfoundlands are known for their size and muscular build. Not only are they tall and heavy, they have the softest, cushiest coats, which make them look even bigger. Nevertheless, underneath the thick coat is a heavy pup who can weigh even above 150 pounds once fully-grown. On average, Newfies weigh anywhere between 100 and 150 pounds and stand around 26 to 28 inches tall at the shoulder.
Having said that, it’s completely normal for some Newfoundlands to fall slightly outside of the usual breed standards. Typically, they might be heavier and taller. However, although chubby pups look cute, you shouldn’t overfeed your dog to the point of obesity, as this is a huge risk factor for many health concerns and diseases. If you’re worried about your Newfie’s size, we recommend you consult with your veterinarian to find a suitable diet, caloric intake, and screen for any underlying health issues.
Additionally, this is why it’s particularly important that your Newfoundland puppy gets the correct nourishment he needs to grow that adorable little body into a healthy adult one. Check out these guides on best dog food for puppies here.
In addition to that, a Newfie’s size is also influenced by its diet, gender, the size of its parents, or even how much they exercise. For this reason, it’s especially important you feed your dog the right amount of food to promote their proper development and maintain a healthy weight.
Are There Different Sizes Of Newfoundlands?
As we briefly mentioned, the Newfoundland size can, in fact, vary between males and females. Like with many other large and giant breed dogs, there’s a considerable difference between male and female Newfies.
Let’s take a closer look at the Newfoundland size chart comparing males and females:
|28 inches on average
|26 inches on average
*A dog’s height is measured from the withers, also known as their shoulder blades.
As we can see from the Newfoundland size chart above, males are typically a few inches taller and they can be up to 50 pounds heavier than females. A male Newfoundland usually weighs between 130 and 150 pounds and stands about 28 inches tall at the shoulder. Female Newfoundlands tend to weigh between 100 and 120 pounds with an average height of 26 inches.
Newfoundland Size Charts & Growth Patterns – Month Wise
Like other large and giant breeds, the Newfoundland experiences its fastest growth in the first 6 months from birth. By that time, Newfies are already pretty large dogs and they’ll continue to get bigger and bigger up until their second birthday. However, like other dogs, Newfies usually reach their adult height sooner than they reach their adult weight. So don’t be surprised if your puppy stops growing in height around their first birthday, they will continue to gain weight and girth even after that.
Let’s take a look at the average Newfoundland size chart by age (males):
Looking at the Newfoundland size chart above, we learn that this breed tends to reach half its adult height already at 3 months old. By 6 months old, they’ve likely reached half their adult weight and around ¾ of their adult height. Around their first birthday, Newfies have reached almost, if not all of their adult height, and most of their adult weight. By then, their growth has considerably slowed down, and the weight gain isn’t as noticeable anymore. We can typically expect a Newfoundland puppy to finish growing by the time they turn 2 years old.

Newfoundland Size: Frequently Asked Questions
How Big Is A Full-Grown Newfoundland?
A full-grown Newfoundland weighs between 100 and 150 pounds and stands 26-28 inches tall at the shoulder. As with many other larger breeds, males tend to be heavier and taller than females. On average, male Newfoundlands weigh between 130 and 150 pounds with a height of 28 inches at the shoulder. Female Newfoundlands weigh between 100 and 120 pounds and they’re about 26 inches tall.
You can calculate their potential adult weight at 23 weeks by taking what they weigh at that age and multiplying it by two.
A different formula you could use is:
- Growth = current weight / current age in weeks
- Adult weight = Growth x 52 (number of weeks in one year)
So, for example, if your 12-week old pup weighs 18 pounds. You simply divide the current weight by their age in weeks and multiply the result with 52:
18/ 12 = 1.5
1.5 x 52= 78 pounds
78 pounds would be the expected weight of your adult-sized Newfoundland.
Is Newfoundland Considered A Giant Breed?
The Newfoundland is considered a giant-sized breed. They’re heavy, tall, strong, and have a muscular build. Although Newfoundlands don’t require as much exercise as some other large and giant breed dogs, they would still thrive best in a spacious home where they have plenty of room to move around and feel comfy.
To conclude, a gentle and noble giant, the Newfoundland is a wonderful pet for singles and families alike. If you’ve got your eyes set on the cuddly Newfie, it only makes sense to be fully aware about your puppy’s growth stages from the moment you bring them home and up until they reach adulthood.
