Canine Pregnancy Calculation:
| From: | To: |
The Puppy Due Date Calculator estimates when a pregnant dog will deliver her puppies based on the breeding date. It uses the standard canine gestation period of approximately 63 days (9 weeks).
The calculator uses a simple formula:
Explanation: Canine pregnancy typically lasts between 58-68 days, with 63 days being the average. This calculator provides the expected due date based on this average.
Details: The 63-day gestation period is counted from the date of ovulation, not necessarily from the first mating. Dogs can conceive from multiple matings over several days.
Tips: Enter the known or estimated breeding date. For best accuracy, use the date confirmed by progesterone testing or veterinary examination.
Q1: Is 63 days exact for all dogs?
A: No, normal gestation can range from 58-68 days. Smaller breeds often deliver earlier, larger breeds may go longer.
Q2: What if I don't know the exact breeding date?
A: Use the earliest possible date and monitor for signs of labor starting around day 58.
Q3: When should I take my dog to the vet?
A: Schedule a prenatal checkup around day 45 for an ultrasound or x-ray to confirm pregnancy and count puppies.
Q4: What are signs of impending labor?
A: Temperature drop below 99°F, nesting behavior, loss of appetite, and restlessness typically occur 12-24 hours before delivery.
Q5: When should I be concerned?
A: If no puppies arrive by day 65, consult your vet. After day 68, veterinary assistance is recommended.
