Average Litter Size of Bull Terrier
Researchers from the Norwegian School of Veterinary Science did a study where they counted the numbers of puppies in 36 different Bull Terrier birth litters.
From this study, the researchers found that the average number of puppies that Bull Terriers can have is 5 puppies. Also, the Bull Terrier can have as few as 1 puppies per litter and as many as 9 puppies per litter.
See how the litter size of the Bull Terrier compares to that of other dog breeds below:

Calculator to Predict How Many Puppies Bull Terrier Will Have
Bull 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 Bull 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 Bull 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 Bull Terrier litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Bull Terrier will have based on the age, and method of pregnancy for a Bull Terrier
The calculator tells you how many puppies your Bull Terrier will have if your Bull 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 Bull 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 Bull Terrier at different ages. This table applies to a Bull 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 Bull Terrier Puppy Weigh at Birth?
Veterinarian researchers did a study to find out how much Bull Terrier puppies weigh at birth. These researchers weighed 25 Bull Terrier puppies at birth.
Based on the study of the weight of 25 Bull Terrier puppies, the average weight of the Bull Terrier at birth is 330 grams (11.6 ounces). The birth weight of the Bull Terrier puppy typically ranges from 273 grams (9.6 ounces) to 350 grams (12.3 ounces).
16 ounces equal one pound.
The factors that affect the weight of a Bull 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.
Furthermore, according to another research study that weighed Bull Terrier puppies from 2 litters, Bull Terriers can weigh 300–450 grams at birth.
How Big Will a Bull Terrier Puppy Get?
A Bull Terrier puppy will grow up to weigh around 35 to 75 pounds. Furthermore, a Bull Terrier puppy will grow up to be 21 to 22 inches tall at the shoulder.

How Much is a Bull Terrier Puppy
The average price of a Bull Terrier puppy is $1800. The price of a Bull Terrier puppy ranges from $1300 to $2000.
Since the Bull Terrier has an average litter size of 5, therefore a Bull Terrier litter birth is worth $9000.

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

Conclusion on Bull Terrier Litter Size
Bull Terriers can have 5 puppies per litter birth on average. The number of puppies that a Bull Terrier will have depends on factors such as the age of the Bull Terrier and the method of pregnancy (natural or artificial insemination).
Breeding Bull Terriers the right way requires expertise and should be done after sufficient training.
Also, you should work closely with a veterinarian when breeding a Bull 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 Bull Terrier gets the right treatment necessary to make healthy puppies.
The litter size research study that we used for this article was conducted on Bull 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.
