1. What is the Canine Gestation Period?

The canine gestation period averages 63 days from ovulation (about 58-68 days from mating). This calculator helps estimate the due date and track pregnancy progress for dogs.

2. How Does the Calculator Work?

The calculator uses the standard canine gestation period:

Where:

• Mating Date — Date when breeding occurred
• 63 days — Average gestation period for dogs

Note: Actual delivery may occur 1-2 days before or after the calculated date.

3. Stages of Canine Pregnancy

Details:

• Weeks 1-3: Embryo development, little visible change
• Weeks 4-5: Weight gain begins, nipples enlarge
• Weeks 6-7: Visible abdominal enlargement
• Week 8-9: Nesting behavior, milk production
