Dogs are pregnant for about 63 days on average — roughly nine weeks. The actual range is typically 58 to 68 days. Because the exact date of conception can be hard to pin down, your vet may estimate the due date using ultrasound or hormone testing.
Pro tip: Gestation length is fairly consistent across breeds, from Chihuahuas to Great Danes.
timeline The Three Stages
Pregnancy divides into three roughly three-week stages. In the first, fertilized eggs implant and there are few outward signs. In the second, the puppies develop rapidly and your dog's belly begins to swell. In the third, the puppies finish developing and your dog prepares for labor.

favorite Caring for a Pregnant Dog
A pregnant dog needs good nutrition, gentle exercise, and regular vet checkups. In the final third, switch to a higher-calorie diet to support the growing puppies. Prepare a quiet, comfortable whelping area about a week before the due date.
Pro tip: A drop in body temperature below 100°F often signals labor will begin within 24 hours.
