The calculator uses the simple formula:
Where:
Explanation: The calculator adds 63 days to the mating date to estimate the whelping date. This is based on the average canine gestation period.
Details: Knowing the expected due date helps prepare for whelping, schedule veterinary checkups, and monitor the pregnancy's progress.
Tips: Enter the exact mating date if known. If unsure, use the first possible mating date. The actual whelping may occur between 58-68 days after mating.
Q1: Is 63 days exact for all dogs?
A: No, gestation typically ranges from 58-68 days. Smaller breeds often deliver earlier than larger breeds.
Q2: When should I take my dog to the vet?
A: Schedule a prenatal checkup about 3-4 weeks after mating for confirmation and ultrasound.
Q3: What are signs of approaching labor?
A: Nesting behavior, temperature drop (below 99°F), loss of appetite, and restlessness typically occur 12-24 hours before labor.
Q4: Can the due date be predicted more accurately?
A: Ultrasound at day 28-35 or progesterone testing can provide more precise timing.
Q5: What if my dog goes past 63 days?
A: Consult your veterinarian if your dog reaches day 65 without signs of labor.
