Average Litter Size of Newfoundland
Researchers from the Norwegian School of Veterinary Science did a study where they counted the numbers of puppies in 57 different Newfoundland birth litters.
From this study, the researchers found that the average number of puppies that Newfoundlands can have is 6 puppies. Also, the Newfoundland can have as few as 1 puppies per litter and as many as 12 puppies per litter.
See how the litter size of the Newfoundland compares to that of other dog breeds below:

Calculator to Predict How Many Puppies Newfoundland Will Have
Newfoundland Litter Size Predictor
According to the result of the research carried out by researchers from the Norwegian School of Veterinary Science, the number of puppies a Newfoundland will have depends on the following main factors:
- The size of the breed (most important factor): Giant dog breeds tend to have a bigger litter size, while smaller breeds give birth to a smaller number of puppies
- The method of mating: Natural mating results in a larger litter size than artificial insemination.
- The age of the female dog: Check out the chart below to see how many puppies a female Newfoundland is likely to have at different ages.
According to research, the following factors do not affect litter size:
- The time of the year of the litter was born (season of birth): Although, from the study, litters born in the Spring seem to be larger than litters from other seasons, however, the difference was not of significance.
- The number of times a female dog has given birth in the past (known as parity): The age of the female dog is more important to the extent that it makes parity insignificant.
Based on the important factors that affect litter size, the researchers from the Norwegian School of Veterinary Science developed formulas for predicting the litter size of dogs.
We have developed the Newfoundland litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Newfoundland will have based on the age, and method of pregnancy for a Newfoundland
The calculator tells you how many puppies your Newfoundland will have if your Newfoundland gets pregnant today. The calculator assumes that the length of pregnancy will be two months.
Note that we are NOT in any way encouraging you to breed your Newfoundland. Dog breeding requires expertise. If you want to be breeding dogs, get the necessary training. Also, work closely with a veterinarian when breeding a dog.
The table below shows the average litter size to expect from a Newfoundland at different ages. This table applies to a Newfoundland that conceives through natural mating.
| Age (Years) | Average Litter Size | Litter Size Range |
|---|---|---|
| 2 | 8 puppies | 6 to 9 puppies |
| 3 | 7 puppies | 6 to 9 puppies |
| 4 | 7 puppies | 5 to 10 puppies |
| 5 | 7 puppies | 4 to 10 puppies |
| 6 | 7 puppies | 4 to 10 puppies |
| 7 | 6 puppies | 3 to 10 puppies |
| 8 | 6 puppies | 2 to 10 puppies |
| 9 | 5 puppies | 1 to 9 puppies |
How Much Does the Newfoundland Puppy Weigh at Birth?
Veterinarian researchers did a study to find out how much Newfoundland puppies weigh at birth. These researchers weighed 21 Newfoundland puppies at birth.
Based on the study of the weight of 21 Newfoundland puppies, the average weight of the Newfoundland at birth is 600 grams (21.2 ounces). The birth weight of the Newfoundland puppy typically ranges from 550 grams (19.4 ounces) to 670 grams (23.6 ounces).
16 ounces equal one pound.
The factors that affect the weight of a Newfoundland puppy at birth include the size, weight, and age of the mother.
Importantly, research has also shown that female dogs that give birth at ages between 2 and 8 years give birth to puppies that are heavier than puppies birthed by younger or older female dogs.
How Big Will a Newfoundland Puppy Get?
A Newfoundland puppy will grow up to weigh around 100 to 150 pounds. Furthermore, a Newfoundland puppy will grow up to be 2 feet, 1 inch to 2 feet, 5 inches tall at the sho.

How Much is a Newfoundland Puppy
The average price of a Newfoundland puppy is $2160. The price of a Newfoundland puppy ranges from $1875 to $2500.
Since the Newfoundland has an average litter size of 6, therefore a Newfoundland litter birth is worth $12960.

How Long is a Newfoundland Pregnant?
Newfoundlands are pregnant for 63 days on average (2 months) after conception. However, this is an average value. The length of pregnancy in Newfoundlands can range from 58-68 days.
However, note that it is difficult to know the exact day that your Newfoundland conceives because conception may not happen at the same time that mating happens.
Sperm can live inside a female Newfoundland for several days after mating before conception occurs.
How to Ensure a Successful Pregnancy in Newfoundland
To ensure that your Newfoundland successfully gets pregnant and deliver its puppies, here at the things you can do:
- Feed your Newfoundland well: A good diet will ensure that your Newfoundland has the nutrients and the energy it needs to get pregnant and maintain the pregnancy.
- Make sure your Newfoundland is in good health: Ensure you take your Newfoundland to the Vet care regularly for checkups, make sure your Newfoundland gets regular exercise. Also, make sure that your is not overweight or underweight.

Conclusion on Newfoundland Litter Size
Newfoundlands can have 6 puppies per litter birth on average. The number of puppies that a Newfoundland will have depends on factors such as the age of the Newfoundland and the method of pregnancy (natural or artificial insemination).
Breeding Newfoundlands the right way requires expertise and should be done after sufficient training.
Also, you should work closely with a veterinarian when breeding a Newfoundland. There are a lot of nuances involved in breeding a dog, which we do not have the time or the space to discuss here.
However, working with a veterinarian will ensure that your Newfoundland gets the right treatment necessary to make healthy puppies.
The litter size research study that we used for this article was conducted on Newfoundlands in Norway. However, the authors of the research believe that the results can be generalized to other countries that have similar dog management systems as Norway.
