Calculator to Predict How Many Puppies Australian Terrier Will Have

Australian Terrier Litter Size Predictor

Your Australian 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 Australian 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 Australian 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.

We have developed the Australian Terrier litter size calculator above based on their formulas. Use the calculator to predict how many puppies a Australian Terrier will have based on the age, and method of pregnancy for a Australian Terrier

The calculator tells you how many puppies your Australian Terrier will have if your Australian Terrier 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 Australian Terrier. 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 Australian Terrier at different ages. This table applies to a Australian Terrier that conceives through natural mating.

Age (Years) Average Litter Size Litter Size Range
2 4 puppies 3 to 4 puppies
3 4 puppies 3 to 5 puppies
4 4 puppies 3 to 5 puppies
5 4 puppies 3 to 5 puppies
6 4 puppies 2 to 5 puppies
7 4 puppies 2 to 6 puppies
8 4 puppies 2 to 6 puppies
9 3 puppies 1 to 6 puppies

Australian Terriers are pregnant for 63 days on average (2 months) after conception. However, this is an average value. The length of pregnancy in Australian Terriers can range from 58-68 days.

However, note that it is difficult to know the exact day that your Australian Terrier conceives because conception may not happen at the same time that mating happens.

Sperm can live inside a female Australian Terrier for several days after mating before conception occurs.
