Dog Pregnancy Formula:
DD (due date), MD (mating date)
| From: | To: |
The Dog Pregnancy Calculator estimates the due date for pregnant dogs based on the mating date. In the UK, the standard gestation period for dogs is approximately 63 days from the mating date.
The calculator uses the simple formula:
Where:
Explanation: The calculation adds exactly 63 days to the mating date to estimate the due date for the dog's pregnancy.
Details: Knowing the expected due date helps dog owners and breeders prepare for whelping, schedule veterinary check-ups, and monitor the pregnancy's progress.
Tips: Enter the exact mating date for the most accurate prediction. The calculator will add 63 days to this date to determine the due date.
Q1: Is 63 days exact for all dogs?
A: While 63 days is the average, gestation can range from 58-68 days depending on the breed and individual dog.
Q2: When should I take my dog to the vet during pregnancy?
A: Schedule a vet visit shortly after mating to confirm pregnancy, and again around day 45 for ultrasound/X-rays to count puppies.
Q3: What are signs of impending labor in dogs?
A: Nesting behavior, temperature drop (below 37.8°C), loss of appetite, and restlessness typically occur 12-24 hours before labor.
Q4: Should I adjust my dog's diet during pregnancy?
A: Yes, gradually increase food by 15-25% by week 5-6, switching to puppy food for higher calories and nutrients.
Q5: How accurate is this calculator?
A: It provides a good estimate, but individual variations mean the actual due date may vary by a few days in either direction.
