How to Use This Calculator
- Select the dog breed from the dropdown menu. This helps determine an estimated litter size based on breed characteristics.
- Enter the mating date. This is the date when the dog was bred, which is used to calculate the estimated due date.
- (Optional) If you have information about the dog's uterine size in cm, you can enter it here. This can help refine the litter size estimate, as larger uteruses may indicate a larger litter.
- Click the "Calculate" button to generate estimates for pregnancy duration, litter size, and due date.
