Pregnancy week by week at a glance
| Week | Days | Stage | Main task |
|---|---|---|---|
| Week 1 | 0–7 | Fertilization and first cell divisions | No visit needed yet. If you are planning ahead, book the day-25 to day-30 ultrasound now. |
| Week 2 | 8–14 | Embryos travel to the uterus | Nothing routine this week. |
| Week 3 | 15–21 | Implantation | Plan the confirmation scan for the end of this week or the next. |
| Week 4 | 22–28 | Confirmation window | Abdominal ultrasound at about day 25 to 30 confirms pregnancy and heartbeats. It is not reliable for counting puppies. |
| Week 5 | 29–35 | Organs form | Discuss diet and any health concerns at this point. |
| Week 6 | 36–42 | Skeletons begin to harden | Nothing routine unless she is unwell. |
| Week 7 | 43–49 | Fully formed, rapid growth | Book the X-ray for days 50 to 55. |
| Week 8 | 50–56 | Count the puppies | X-ray at about day 50 to 55 gives a count and a view of head size against her pelvis. |
| Week 9 | 57–63+ | Labor window | Know your emergency clinic. Call if she goes more than a few days past day 65 from ovulation without labor. |
Questions
Frequently asked questions
How can I tell how far along my dog is?
Count the days from ovulation (or from the mating date if that is all you have). Divide by seven for the week. A vet can also estimate from an ultrasound measurement if the dates are unknown, which is most accurate in the first half of pregnancy.
What if I do not know when she mated?
Ask your vet. Ultrasound can estimate gestational age, and an X-ray after about day 45 to 50 shows how developed the skeletons are. The estimate is wider than a date from hormone testing.
How many weeks pregnant is a dog at 30 days?
Day 30 falls in week 5. Embryos have become fetuses and the ultrasound window for confirmation (days 25 to 30) is just ending.
