Average Litter Size of Collie
Researchers from the Norwegian School of Veterinary Science did a study where they counted the numbers of puppies in 101 different Collie birth litters.
From this study, the researchers found that the average number of puppies that Collies can have is 5 puppies. Also, the Collie can have as few as 1 puppies per litter and as many as 10 puppies per litter.
See how the litter size of the Collie compares to that of other dog breeds below:

Calculator to Predict How Many Puppies Collie Will Have
Collie 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 Collie 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 Collie 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 Collie litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Collie will have based on the age, and method of pregnancy for a Collie
The calculator tells you how many puppies your Collie will have if your Collie 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 Collie. 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 Collie at different ages. This table applies to a Collie that conceives through natural mating.
| Age (Years) | Average Litter Size | Litter Size Range |
|---|---|---|
| 2 | 6 puppies | 5 to 7 puppies |
| 3 | 6 puppies | 4 to 8 puppies |
| 4 | 6 puppies | 4 to 8 puppies |
| 5 | 6 puppies | 4 to 8 puppies |
| 6 | 6 puppies | 3 to 8 puppies |
| 7 | 5 puppies | 3 to 8 puppies |
| 8 | 5 puppies | 2 to 8 puppies |
| 9 | 5 puppies | 1 to 8 puppies |
How Big Will a Collie Puppy Get?
A Collie puppy will grow up to weigh around 50 to 70 pounds. Furthermore, a Collie puppy will grow up to be 22 to 26 inches all at the shoulder.

How Much is a Collie Puppy
The average price of a Collie puppy is $1480. The price of a Collie puppy ranges from $1000 to $1800.
Since the Collie has an average litter size of 5, therefore a Collie litter birth is worth $7400.

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

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