1. What is the Dog Due Date Calculator?

The Dog Due Date Calculator estimates when a pregnant dog will give birth based on the breeding date. The average canine pregnancy lasts approximately 63 days (9 weeks) from ovulation.

2. How Does the Calculator Work?

The calculator uses the standard canine gestation period:

Where:

• Breeding Date — Date of successful mating
• 63 days — Average canine gestation period

Explanation: While the average is 63 days, actual delivery can occur between 58-68 days after breeding.

3. Importance of Due Date Calculation

Details: Knowing the expected due date helps prepare for whelping, schedule veterinary checkups, and monitor for potential complications.

4. Using the Calculator

Tips: Enter the known breeding date. For best accuracy, use the date confirmed by veterinary methods like progesterone testing.

5. Frequently Asked Questions (FAQ)

Q1: Is 63 days exact for all dogs?
A: No, normal gestation can range from 58-68 days. Smaller breeds often deliver earlier than larger breeds.

Q2: When should I prepare the whelping area?
A: Prepare by day 55. Monitor temperature drops which typically occur 12-24 hours before labor.

Q3: What if I don't know the exact breeding date?
A: Ultrasound can estimate fetal age, or count back from the LH surge date if progesterone testing was done.

Q4: When should I be concerned about overdue pregnancy?
A: Consult your vet if no signs of labor appear by day 65-66, especially for large breed dogs.

Q5: Can this calculator predict litter size?
A: No, this only estimates due date. Ultrasound or X-ray (after day 45) can determine litter size.
