Question: How long is a dog's pregnancy (gestation)?
Answer: Pregnancy in dogs, also called gestation, typically lasts 63 days (about nine weeks). The duration of a dog's pregnancy can fall in the range of 58 to 68 days.

Though estrus (heat cycles) can vary from breed to breed, the normal gestation period falls within the same range for all dogs, regardless of breed.
