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

Calculator to Predict How Many Puppies Pyrenean Mastiff Will Have
Pyrenean Mastiff 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 Pyrenean Mastiff 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 Pyrenean Mastiff 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 Pyrenean Mastiff litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Pyrenean Mastiff will have based on the age, and method of pregnancy for a Pyrenean Mastiff
The calculator tells you how many puppies your Pyrenean Mastiff will have if your Pyrenean Mastiff 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 Pyrenean Mastiff. 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 Pyrenean Mastiff at different ages. This table applies to a Pyrenean Mastiff 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 Long is a Pyrenean Mastiff Pregnant?
Pyrenean Mastiffs are pregnant for 63 days on average (2 months) after conception. However, this is an average value. The length of pregnancy in Pyrenean Mastiffs can range from 58-68 days.
However, note that it is difficult to know the exact day that your Pyrenean Mastiff conceives because conception may not happen at the same time that mating happens.
Sperm can live inside a female Pyrenean Mastiff for several days after mating before conception occurs.
How to Ensure a Successful Pregnancy in Pyrenean Mastiff
To ensure that your Pyrenean Mastiff successfully gets pregnant and deliver its puppies, here at the things you can do:
- Feed your Pyrenean Mastiff well: A good diet will ensure that your Pyrenean Mastiff has the nutrients and the energy it needs to get pregnant and maintain the pregnancy.
- Make sure your Pyrenean Mastiff is in good health: Ensure you take your Pyrenean Mastiff to the Vet care regularly for checkups, make sure your Pyrenean Mastiff gets regular exercise. Also, make sure that your is not overweight or underweight.
Conclusion on Pyrenean Mastiff Litter Size
Pyrenean Mastiffs can have 5 puppies per litter birth on average. The number of puppies that a Pyrenean Mastiff will have depends on factors such as the age of the Pyrenean Mastiff and the method of pregnancy (natural or artificial insemination).
Breeding Pyrenean Mastiffs the right way requires expertise and should be done after sufficient training.
Also, you should work closely with a veterinarian when breeding a Pyrenean Mastiff. 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 Pyrenean Mastiff gets the right treatment necessary to make healthy puppies.
The litter size research study that we used for this article was conducted on Pyrenean Mastiffs 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.
