Dog Pregnancy Calculator

Dogs are pregnant for approximately 63 days (about 9 weeks) from the date of ovulation. However, the range can be 58-68 days depending on breed size and when mating occurred relative to ovulation.

A veterinarian can confirm pregnancy via ultrasound around days 25-28, or by abdominal palpation around days 28-35. X-rays can count puppies after day 45 when skeletons calcify.

Early signs include decreased appetite (weeks 2-3), enlarged nipples (week 3-4), and weight gain. Later signs include visible belly growth (week 5-6), nesting behavior, and increased appetite.

Count 63 days from the breeding/mating date. If you know the ovulation date, add 63 days. If unsure of exact timing, your vet can estimate based on fetal development via ultrasound.

Schedule an initial pregnancy confirmation at 25-28 days, a check-up and possible x-ray at 45-50 days to count puppies, and be ready to contact your vet when labor begins.

Continue regular food for weeks 1-4. From week 5, gradually increase food by 25-50% using high-quality puppy food or pregnancy formula. Provide small, frequent meals as her belly grows.
