Average Litter Size of Boston Terrier
Researchers from the Norwegian School of Veterinary Science did a study where they counted the numbers of puppies in 46 different Boston Terrier birth litters.
From this study, the researchers found that the average number of puppies that Boston Terriers can have is 4 puppies. Also, the Boston Terrier can have as few as 1 puppies per litter and as many as 8 puppies per litter.
See how the litter size of the Boston Terrier compares to that of other dog breeds below:

Calculator to Predict How Many Puppies Boston Terrier Will Have
Boston Terrier 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 Boston Terrier 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 Boston Terrier 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 Boston Terrier litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Boston Terrier will have based on the age, and method of pregnancy for a Boston Terrier
The calculator tells you how many puppies your Boston Terrier will have if your Boston Terrier 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 Boston Terrier. 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 Boston Terrier at different ages. This table applies to a Boston Terrier that conceives through natural mating.
| Age (Years) | Average Litter Size | Litter Size Range |
|---|---|---|
| 2 | 4 puppies | 3 to 6 puppies |
| 3 | 4 puppies | 3 to 6 puppies |
| 4 | 4 puppies | 3 to 6 puppies |
| 5 | 4 puppies | 2 to 6 puppies |
| 6 | 4 puppies | 2 to 6 puppies |
| 7 | 4 puppies | 1 to 7 puppies |
| 8 | 4 puppies | 1 to 7 puppies |
| 9 | 3 puppies | 0 to 7 puppies |
How Much Does the Boston Terrier Puppy Weigh at Birth?
Veterinarian researchers did a study to find out how much Boston Terrier puppies weigh at birth. These researchers weighed 20 Boston Terrier puppies at birth.
Based on the study of the weight of 20 Boston Terrier puppies, the average weight of the Boston Terrier at birth is 200 grams (7.1 ounces). The birth weight of the Boston Terrier puppy typically ranges from 178 grams (6.3 ounces) to 226 grams (8.0 ounces).
16 ounces equal one pound.
The factors that affect the weight of a Boston Terrier 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 Boston Terrier Puppy Get?
A Boston Terrier puppy will grow up to weigh around 10 to 25 pounds. Furthermore, a Boston Terrier puppy will grow up to be 12 to 15 inches tall at the shoulder.

How Much is a Boston Terrier Puppy
The average price of a Boston Terrier puppy is $1670. The price of a Boston Terrier puppy ranges from $1200 to $1999.

How Long is a Boston Terrier Pregnant?
Boston Terriers are pregnant for 63 days on average (2 months) after conception. However, this is an average value. The length of pregnancy in Boston Terriers can range from 58-68 days.
However, note that it is difficult to know the exact day that your Boston Terrier conceives because conception may not happen at the same time that mating happens.
Sperm can live inside a female Boston Terrier for several days after mating before conception occurs.

Conclusion on Boston Terrier Litter Size
Boston Terriers can have 4 puppies per litter birth on average. The number of puppies that a Boston Terrier will have depends on factors such as the age of the Boston Terrier and the method of pregnancy (natural or artificial insemination).
Breeding Boston Terriers the right way requires expertise and should be done after sufficient training.
Also, you should work closely with a veterinarian when breeding a Boston Terrier. 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 Boston Terrier gets the right treatment necessary to make healthy puppies.
The litter size research study that we used for this article was conducted on Boston Terriers 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.
