Dog Pregnancy Calculator with Due Date and Week by Week Tracker
This free dog pregnancy calculator helps you estimate your dog's whelping timeline from the mating date. Enter the mating date and instantly get an average due date, a 58 to 68 day delivery window, the current pregnancy week, and a complete week by week tracker covering all 9 weeks of dog gestation.
Most dog pregnancies average around 63 days from mating, but actual delivery varies between dogs and litters. That is why this dog pregnancy calculator by days shows both a precise average date and a broader expected range — so you can plan with confidence rather than rely on a single estimate.
The tool works on any device in any browser. No app download, no signup, and no cost — just enter the mating date and get the full pregnancy timeline immediately.

Dog Pregnancy Week by Week — Stages Overview
This dog pregnancy calculator week by week covers the full 9-week gestation period across three stages:
- Week 1 to 2 — Early stage: Fertilization and embryo cell division begin. Few outward signs are visible.
- Week 3 to 5 — Mid stage: Implantation occurs, organs begin forming, and physical changes like nipple growth and belly rounding become noticeable.
- Week 6 to 9 — Final stage: Rapid puppy growth, nesting behavior, and preparation for whelping. The delivery window begins at day 58.
Each week in the tracker shows puppy development details, common symptoms to expect, and a practical care tip. Your current week is highlighted automatically based on the mating date.
Important Note About Due Date Estimates
This dog pregnancy calculator estimates the whelping timeline from the mating date. Because the actual conception date can differ from the mating date, delivery may fall earlier or later than the average estimate. Use both the average due date and the full 58 to 68 day range for planning, and always confirm with your veterinarian for medical guidance.
Frequently Asked Questions
How long is a dog pregnant?
Dog pregnancy averages about 63 days from mating, but the actual delivery window runs from day 58 to day 68. This calculator shows both the average due date and the full expected range so you can plan for the complete whelping window.
What does a dog pregnancy calculator week by week show?
The week by week tracker shows puppy development, common symptoms, and care tips for each of the 9 weeks of pregnancy. The current week is highlighted automatically based on the mating date you enter.
Can I track dog pregnancy by days with this calculator?
Yes. The calculator shows the exact pregnancy day alongside the current week so you can track the full gestation both by days and by week from the mating date.
Is this the best dog pregnancy calculator for all breed sizes?
This calculator includes small, medium, and large breed size options. Small breeds average 62 days, medium breeds 63 days, and large breeds 64 days. The full 58 to 68 day range is always shown because timing varies between individual dogs.
Can I use this dog pregnancy calculator app on my phone?
Yes. This tool works in any mobile browser on iPhone or Android with no app download needed. Enter the mating date and get the full due date, week tracker, and whelping range on any device.
Why does this calculator show a date range instead of one exact date?
The mating date does not always match the exact conception date, so dog pregnancy is better planned as a window. This calculator shows the average due date and the full 58 to 68 day expected range together for more reliable planning.
Is this dog pregnancy calculator medically accurate?
This is a planning estimate based on the mating date, not a substitute for a veterinarian. Actual conception timing may differ from the mating date. Always consult your vet for confirmation, imaging, or any urgent symptoms.
