1. What Is Dog Pregnancy Week Calculator?

The Dog Pregnancy Week Calculator helps breeders and pet owners track the progression of canine pregnancy by calculating the exact week and day of gestation based on the mating date and current date.

2. How Does The Calculator Work?

The calculator uses the following formula:

Where:

• \( Current\ Date \) — The date you want to check pregnancy progress
• \( Mating\ Date \) — The date when breeding occurred
• \( \lfloor \rfloor \) — Floor function (rounds down to nearest whole number)

Explanation: The calculator determines the total days between mating and current date, then divides by 7 to calculate complete weeks, with remaining days shown separately.

3. Importance Of Tracking Pregnancy Weeks

Details: Accurate pregnancy tracking is crucial for proper prenatal care, anticipating whelping dates, monitoring fetal development stages, and preparing for delivery.

4. Using The Calculator

Tips: Enter the exact mating date and current date. The calculator will display the pregnancy week and remaining days. Normal dog pregnancy lasts approximately 63 days (9 weeks).
