1. What is Dog Pregnancy Calculator?

The Dog Pregnancy Calculator helps determine how many weeks a dog has been pregnant based on the mating date and current date. It calculates the gestation period in weeks and days, providing valuable information for dog breeders and owners.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Pregnancy Weeks} = \left\lfloor \frac{\text{Current Date} - \text{Mating Date}}{7} \right\rfloor \]

Where:

\( \text{Current Date} \) — Today's date or any specified date
\( \text{Mating Date} \) — The date when breeding occurred
\( \left\lfloor \right\rfloor \) — Floor function (rounds down to nearest whole number)

Explanation: The calculator calculates the difference in days between the current date and mating date, then converts this to weeks by dividing by 7 and rounding down.

3. Importance of Tracking Dog Pregnancy

Details: Accurately tracking dog pregnancy is crucial for proper prenatal care, preparing for whelping, monitoring fetal development, and ensuring the health of both mother and puppies.

4. Using the Calculator

Tips: Enter the exact mating date and current date. The calculator will show the pregnancy duration in weeks and days, plus the estimated time remaining until the due date (average 63-day gestation).

5. Frequently Asked Questions (FAQ)
