Dog Pregnancy Calculator: Estimate Your Dog’s Due Date

The Dog Pregnancy Calculator is a useful tool for estimating key milestones in a dog's pregnancy. By entering the mating date and selecting the breed size, users can see important pregnancy events such as implantation, ultrasound viability, and the expected due date. This tool is especially helpful for breeders and pet owners who want to prepare for their dog's whelping period.

How the Calculator Works

Dog pregnancies typically last between 58 to 68 days, with an average gestation period of around 63 days. The calculator estimates important dates using the following formula:

The gestation period varies based on breed size:

• Small breeds: ~60 days
• Medium breeds: ~63 days
• Large breeds: ~65 days
• Giant breeds: ~68 days

How accurate is the Dog Pregnancy Calculator?

The calculator provides an estimate based on the average gestation periods for different breed sizes. However, actual birth dates may vary by several days. Always consult a veterinarian for precise monitoring.
