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.

Calculator to Predict How Many Puppies Japanese Spitz Will Have

Japanese Spitz Litter Size Predictor

Your Japanese Spitz`s Current Age:




Method of Pregnancy

Number of Puppies to Expect:

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
