The Dog Pregnancy Calculator helps breeders and pet owners track the progress of a dog's pregnancy by calculating the number of days since mating. This is important for proper prenatal care and preparation for whelping.
The calculator uses a simple date difference formula:
Where:
Explanation: The calculator determines the number of days between the mating date and current date, then categorizes the pregnancy into stages.
Details: Accurate pregnancy tracking is crucial for proper nutrition, veterinary care, and preparation for delivery. Dogs have a relatively short gestation period (average 63 days), so each day is significant.
Tips: Enter the mating date and current date (defaults to today). The calculator will show days pregnant and current pregnancy stage.
Q1: What is the normal gestation period for dogs?
A: The normal gestation period is 58-68 days, with an average of 63 days from ovulation.
Q2: When should I take my pregnant dog to the vet?
A: First visit should be about 3 weeks after mating for ultrasound confirmation, then again at 6 weeks for X-rays to count puppies.
Q3: How does pregnancy stage affect care?
A: Early pregnancy (0-20 days) needs minimal changes. Mid pregnancy (21-45 days) requires increased nutrition. Late pregnancy (46+ days) needs whelping preparation.
Q4: Can the calculator predict delivery date?
A: It can estimate based on average gestation, but individual dogs may vary by several days.
Q5: What if I don't know the exact mating date?
A: Use your best estimate. Ultrasound at 25-35 days can help estimate conception date more accurately.
