Average Litter Size of Japanese Spitz
Researchers from the Norwegian School of Veterinary Science did a study where they counted the numbers of puppies in 91 different Japanese Spitz birth litters.
From this study, the researchers found that the average number of puppies that Japanese Spitzs can have is 3 puppies. Also, the Japanese Spitz can have as few as 1 puppies per litter and as many as 7 puppies per litter.
See how the litter size of the Japanese Spitz compares to that of other dog breeds below:

Calculator to Predict How Many Puppies Japanese Spitz Will Have
Japanese Spitz 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 Japanese Spitz 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 Japanese Spitz 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 Japanese Spitz litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Japanese Spitz will have based on the age, and method of pregnancy for a Japanese Spitz
The calculator tells you how many puppies your Japanese Spitz will have if your Japanese Spitz 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 Japanese Spitz. 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 Japanese Spitz at different ages. This table applies to a Japanese Spitz 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 is a Japanese Spitz Puppy
The average price of a Japanese Spitz puppy is $2200. The price of a Japanese Spitz puppy ranges from $2200 to $2200.
Since the Japanese Spitz has an average litter size of 3, therefore a Japanese Spitz litter birth is worth $6600.

How Long is a Japanese Spitz Pregnant?
Japanese Spitzs are pregnant for 63 days on average (2 months) after conception. However, this is an average value. The length of pregnancy in Japanese Spitzs can range from 58-68 days.
However, note that it is difficult to know the exact day that your Japanese Spitz conceives because conception may not happen at the same time that mating happens.
Sperm can live inside a female Japanese Spitz for several days after mating before conception occurs.
How to Ensure a Successful Pregnancy in Japanese Spitz
To ensure that your Japanese Spitz successfully gets pregnant and deliver its puppies, here at the things you can do:
- Feed your Japanese Spitz well: A good diet will ensure that your Japanese Spitz has the nutrients and the energy it needs to get pregnant and maintain the pregnancy.
- Make sure your Japanese Spitz is in good health: Ensure you take your Japanese Spitz to the Vet care regularly for checkups, make sure your Japanese Spitz gets regular exercise. Also, make sure that your is not overweight or underweight.
Conclusion on Japanese Spitz Litter Size
Japanese Spitzs can have 3 puppies per litter birth on average. The number of puppies that a Japanese Spitz will have depends on factors such as the age of the Japanese Spitz and the method of pregnancy (natural or artificial insemination).
Breeding Japanese Spitzs the right way requires expertise and should be done after sufficient training.
Also, you should work closely with a veterinarian when breeding a Japanese Spitz. 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 Japanese Spitz gets the right treatment necessary to make healthy puppies.
The litter size research study that we used for this article was conducted on Japanese Spitzs 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.
