1. What is the Dog Due Date Calculator?

The Dog Due Date Calculator estimates when a pregnant dog will give birth based on the mating date. The standard canine gestation period is approximately 63 days (9 weeks) from conception.

2. How Does the Calculator Work?

The calculator uses the standard canine gestation period:

Note: While weight can sometimes influence gestation length, the standard 63-day calculation is most commonly used.

3. Importance of Accurate Due Date

Details: Knowing the expected due date helps prepare for whelping, schedule veterinary checkups, and monitor for potential complications.

4. Using the Calculator

Tips: Enter the known or estimated mating date. For best accuracy, record mating dates when breeding is planned.

5. Frequently Asked Questions (FAQ)

Q1: Is 63 days exact for all dogs?
A: While 63 days is average, normal gestation can range from 58-68 days. Smaller breeds often deliver earlier than larger breeds.

Q2: How accurate is the mating date method?
A: Very accurate if exact mating dates are known. For unknown dates, ultrasound can help estimate due date.

Q3: Does weight affect gestation length?
A: Some evidence suggests larger breeds may have slightly longer gestations, but the difference is typically only 1-2 days.

Q4: When should I prepare the whelping area?
A: Prepare by day 55-58, as some dogs may deliver early. Monitor temperature starting day 58 (drop below 99°F often signals labor within 24 hours).

Q5: What if my dog goes past the due date?
A: Contact your veterinarian if gestation exceeds 68 days, as this may indicate problems requiring intervention.
