| From: | To: |
The Dog Pregnancy Calculator estimates the due date for pregnant dogs based on the mating date. The average canine pregnancy lasts approximately 63 days (9 weeks) from the date of mating.
The calculator uses the simple formula:
Where:
Explanation: The calculation adds exactly 63 days to the mating date to estimate when the dog will give birth.
Details: Knowing the expected due date helps prepare for whelping, schedule veterinary checkups, and monitor for any complications as the due date approaches.
Tips: Enter the exact mating date if known, or the estimated date if uncertain. The calculation assumes a standard 63-day gestation period.
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 take my dog to the vet during pregnancy?
A: Schedule a vet visit within 3 weeks of mating for confirmation, and again around day 45 for ultrasound/x-rays to count puppies.
Q3: How can I tell if my dog is pregnant?
A: Signs include increased appetite, weight gain, nipple enlargement, and behavioral changes. Ultrasound after 25 days or palpation by a vet after 28 days can confirm.
Q4: What if I don't know the exact mating date?
A: Use the earliest possible mating date and monitor closely starting from day 58. Signs of impending labor include nesting behavior and temperature drop.
Q5: Should I change my dog's diet during pregnancy?
A: Yes, gradually increase food quantity and switch to high-quality puppy food in the last 3-4 weeks of pregnancy for proper nutrition.
