MD = Mating Date
| From: | To: |
The dog pregnancy calculation estimates the due date (DD) based on the mating date (MD). The standard gestation period for dogs is approximately 63 days (9 weeks) from the date of mating.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides an estimate of when puppies can be expected. Actual delivery may occur a few days before or after the calculated date.
Details: Knowing the expected due date helps in preparing for whelping, scheduling veterinary check-ups, and monitoring the mother's health during pregnancy.
Tips: Enter the exact mating date for most accurate results. The calculator will add 63 days to determine the expected due date.
Q1: Is 63 days exact for all dogs?
A: While 63 days is average, normal gestation can range from 58-68 days depending on breed and individual factors.
Q2: When should I prepare the whelping area?
A: Prepare by day 55 to allow the mother to become accustomed to the space before delivery.
Q3: What are signs of approaching labor?
A: Nesting behavior, temperature drop (below 99°F), loss of appetite, and restlessness typically occur 24 hours before labor.
Q4: Should I be concerned if delivery is late?
A: Consult your veterinarian if pregnancy extends beyond 65 days to ensure the health of mother and puppies.
Q5: Does litter size affect gestation length?
A: Generally no, though very large litters may deliver slightly earlier and small litters may go slightly longer.
