Calculator to Predict How Many Puppies Glen of Imaal Terrier Will Have

Glen of Imaal Terrier Litter Size Predictor

Your Glen of Imaal Terrier`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 Glen of Imaal Terrier 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 Glen of Imaal Terrier 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.
