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 of gestation based on mating date and current date.

2. How Does The Calculator Work?

The calculator uses a simple mathematical formula:

Where:

• \( Current\ Date \) — Today's date or any specified date
• \( Mating\ Date \) — The date when breeding occurred
• \( \lfloor \rfloor \) — Floor function (rounding down to nearest integer)

Explanation: The calculator determines the number of days between mating date and current date, then divides by 7 to calculate complete weeks of pregnancy.

3. Importance Of Tracking Pregnancy Weeks

Details: Accurate week-by-week tracking is essential for proper prenatal care, anticipating whelping date, monitoring fetal development, and preparing for delivery.

4. Using The Calculator

Tips: Enter the exact mating date and current date (defaults to today). The calculator will display the current pregnancy week with corresponding developmental information.

5. Frequently Asked Questions (FAQ)
