How French Bulldog Gestation Works

The average dog pregnancy lasts 63 days from ovulation, but most breeders do not know the exact ovulation date. If you are breeding naturally, the due date window is wider because sperm can survive inside the female reproductive tract for up to 5 days.

This is why progesterone testing is essential for Frenchies. A vet can identify the LH surge and tell you the optimal breeding window, which gives you a due date accurate within 24 hours. Without progesterone data, you are working with a 10-day window that makes planning a C-section much harder.

Use this calculator to track your pregnancy timeline, but always confirm your plan with your veterinarian. For a full walkthrough of the whelping process, read our complete French Bulldog Whelping Guide.
