Dog Pregnancy Calculator
How to Use the Dog Pregnancy Calculator
Enter the date the dogs mated in the ‘Mating Date’ field and then click on ‘Calculate’. The expected whelping date, also known as the due date, will appear in the ‘Expected Whelping Date’ box.
How It Calculates the Results
The calculator adds the average gestation period for a dog, which is typically 63 days, to the provided mating date. Note that the gestation period can vary by breed and by individual dog, so the expected date is approximate.
Limitations of the Dog Pregnancy Calculator
The calculator provides an estimated whelping date based on an average gestation period. It does not account for variability in the length of a dog’s pregnancy, which can be influenced by breed, size, health, and the number of puppies. We recommend consulting with a veterinarian for more detailed information regarding your dog’s pregnancy.
