If you have recently adopted a female dog, you may be curious about the length of her pregnancy.

Depending on the breed and size of your dog, her pregnancy can range anywhere from 58-68 days on average.

To ensure that your pup has a safe and healthy birth experience, it is important to familiarize yourself with the stages of canine pregnancy and how long they typically last.

The Stages of Canine Pregnancy

The first stage of canine pregnancy lasts for 18-20 days after conception. During this stage, the fertilized eggs will travel through the female’s reproductive system before attaching to the uterine wall. Upon attachment, the eggs will begin to develop into tiny embryos known as fetuses.

The second stage of canine pregnancy occurs between 20-25 days after conception and is marked by rapid growth in the fetuses.

During this time, it is important to ensure that your dog is receiving ample nutrition so that her puppies are well-nourished during their development. This stage also marks when your vet can accurately diagnose a female dog’s pregnancy via ultrasound or X-ray imaging.

The third and final stage of canine pregnancy covers 25-58 days after conception, during which time the fetuses continue to grow rapidly until they are ready for birth.

Towards the end of this period, you may notice changes in your pup’s behavior such as nesting or restlessness—signs which indicate that she is getting close to giving birth.

Additionally, during this time it is important to keep an eye out for any signs of labor such as contractions or heavy panting since these can indicate complications with her delivery.


Knowing how long dogs are pregnant can help you prepare for your pup’s upcoming delivery and make sure that both she and her puppies have safe and healthy birthing experiences.

On average, canine pregnancies last anywhere from 58-68 days depending on the breed and size of your pup; however, these times can vary slightly based on individual circumstances.

If you have any questions or concerns about your dog’s pregnancy or impending delivery, it’s best to contact your vet right away!
