1. What is Dog Gestation Calculator?

The Dog Pregnancy Gestation Calculator estimates the due date for pregnant dogs based on mating date and breed size. It accounts for variations in gestation periods between different dog breeds.

2. How Does the Calculator Work?

The calculator uses the base formula:

Where:

• \( DD \) — Due Date
• \( MD \) — Mating Date

Explanation: The base gestation period is 63 days, with adjustments made based on breed size:

• Small breeds: 58-63 days
• Medium breeds: 60-65 days
• Large breeds: 62-67 days

3. Importance of Accurate Due Date

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 mating date and select the dog's breed size. For best accuracy, use the date of the last mating if multiple breedings occurred.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the due date calculation?
A: The calculation provides an estimate. Actual delivery may vary by ±3-5 days depending on individual factors.

Q2: When should I start monitoring for labor signs?
A: Begin close monitoring from day 58 onward. Take rectal temperature twice daily as temperature drop (below 99°F) usually precedes labor by 12-24 hours.

Q3: Are there signs that delivery is imminent?
A: Yes - nesting behavior, appetite loss, restlessness, vulvar discharge, and temperature drop are common signs.

Q4: Should I be concerned if my dog goes past the due date?
A: Consult your veterinarian if your dog goes more than 2 days past the calculated due date without showing signs of labor.

Q5: Does litter size affect gestation length?
A: Generally no, though some breeders report slightly shorter gestation with larger litters.
