What is a Dog Pregnancy Calculator?
A Dog Pregnancy Calculator estimates expected whelping date and key milestone dates from breeding date and gestation length assumptions.
Formula
Estimated Due Date = Breeding Date + Gestation Days Key Milestones = Breeding Date + Milestone Offsets
Example
If breeding date is February 1 and gestation is 63 days, estimated due date is early April with ultrasound around day 28 and X-ray around day 45.
Common Applications
- Whelping date planning
- Veterinary milestone scheduling
- Maternal nutrition timing
- Whelping area preparation
Tips
- Track temperature and behavior in final week.
- Prepare emergency contacts in advance.
- Use veterinary oversight for first-time litters.
Frequently Asked Questions
How long is dog pregnancy typically?
Canine gestation is commonly around 63 days from ovulation, though practical due-date windows can vary by several days based on breeding timing and individual differences.
When should ultrasound be done?
Ultrasound is often useful around day 25-30 to confirm pregnancy and fetal viability. Your veterinarian can advise exact timing based on breeding history and clinical signs.
When is radiography useful?
Abdominal radiography is commonly used in late gestation, around day 45 or later, to estimate litter size and support whelping preparedness.
Can this calculator predict exact whelping date?
It provides an estimate, not a guarantee. Actual delivery may vary. Always monitor behavior and health closely and maintain veterinary support near expected delivery.
What should I prepare before due date?
Prepare a clean whelping area, emergency contacts, maternal nutrition plan, and neonatal monitoring supplies. Discuss warning signs and intervention thresholds with your veterinarian in advance.
