1. What is the Canine Gestation Period?

The average canine gestation period is approximately 63 days (9 weeks) from the date of mating. This can vary slightly by breed and individual dog, with most dogs delivering between 58-68 days after conception.

2. How Does the Calculator Work?

The calculator uses the standard canine gestation formula:

Where:

• Mating Date — The date when breeding occurred
• 63 days — Average canine gestation period

Note: Actual delivery may occur a few days before or after the calculated date.

3. Importance of Knowing the Due Date

Details: Knowing the expected due date helps with proper prenatal care, preparation for whelping, and scheduling veterinary checkups during pregnancy.

4. Using the Calculator

Tips: Enter the confirmed mating date. For best accuracy, use the date of the last mating if multiple breedings occurred. The calculator will add 63 days to determine the expected due date.

5. Frequently Asked Questions (FAQ)

Q1: Is 63 days exact for all dogs?
A: No, gestation can range from 58-68 days. Smaller breeds often have slightly shorter pregnancies than larger breeds.

Q2: When should I start preparing for whelping?
A: Prepare a whelping box and supplies by day 55. Monitor temperature daily starting day 58, as a drop often precedes labor.

Q3: How accurate is this calculator?
A: It provides an estimate based on averages. Ultrasound or progesterone testing can provide more precise timing.

Q4: What if I don't know the exact mating date?
A: Use the earliest possible date and latest possible date to calculate a range. Ultrasound can help narrow this down.

Q5: When should I contact my vet?
A: If no puppies are delivered by day 65, or if you notice any signs of distress during pregnancy.
