Calculator to Predict How Many Puppies Portuguese Water Dog Will Have

Portuguese Water Dog Litter Size Predictor

Your Portuguese Water Dog`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 Portuguese Water Dog 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 Portuguese Water Dog 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 Portuguese Water Dog litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Portuguese Water Dog will have based on the age, and method of pregnancy for a Portuguese Water Dog

The calculator tells you how many puppies your Portuguese Water Dog will have if your Portuguese Water Dog gets pregnant today. The calculator assumes that the length of pregnancy will be two months.
