Dog Pregnancy Calculation:
| From: | To: |
The Dog Pregnancy Calculator estimates the due date for pregnant dogs based on the mating date. It uses the standard canine gestation period of 63 days to predict when puppies will be born.
The calculator uses the standard dog pregnancy formula:
Where:
Explanation: The average gestation period for dogs is 63 days from the date of mating, though it can vary from 58 to 68 days depending on the breed and individual dog.
Details: Accurate due date prediction helps breeders and owners prepare for whelping, set up appropriate nesting areas, schedule veterinary check-ups, and ensure proper care during the final stages of pregnancy.
Tips: Enter the exact mating date for most accurate results. Keep in mind that the actual delivery may occur a few days before or after the calculated due date. Monitor your dog for signs of labor as the due date approaches.
Q1: Is 63 days exact for all dogs?
A: While 63 days is the average, gestation can range from 58-68 days. Smaller breeds often have shorter pregnancies, while larger breeds may carry longer.
Q2: When should I start preparing for whelping?
A: Begin preparations about 1-2 weeks before the due date. Set up a whelping box in a quiet, warm area and gather necessary supplies.
Q3: What are signs of approaching labor?
A: Signs include nesting behavior, temperature drop (below 100°F), loss of appetite, restlessness, and milk production in the mammary glands.
Q4: Should I count from first or last mating?
A: Count from the first mating, but if multiple matings occurred over several days, the first mating usually provides the most accurate due date.
Q5: When should I contact a veterinarian?
A: Contact your vet if labor doesn't begin within 24 hours of the due date, if strong contractions last more than 2 hours without producing a puppy, or if you notice any concerning symptoms.
