Gestation Period: How Long Are Dogs Pregnant?

Pregnancy in dogs lasts approximately nine weeks or around 63 days from the time when an egg is fertilized, which is the point of conception. However, it is important to note that this can by over several days. As the pregnancy progresses through its three months, it can be divided into three stages.

The three stages include: 

Pregnancy During the First Month

Sperm enters the female’s uterus and enters the uterine lining around the 16th day of pregnancy. It is around day 22 that the fetuses start to develop. In the early stages of pregnancy, your dog probably won’t show any major signs of pregnancy. However, the fourth week may bring morning sickness symptoms, weight gain, and fatigue for your pup. This is when you may start to notice that something is up!

Second Month of Pregnancy

It is common for the fetuses to grow rapidly by the second month of pregnancy. Puppy fetuses begin developing their skeletons, claws, and coats at the end of the second month. Several days after that, the pregnant female will seek out a place to lay for when she gives birth to her puppies. During this month, you’ll notice changes in your pup’s behavior, like an increase in affection or withdrawal from contact and changes in appetite and weight gain.


Third Month of Pregnancy

In the final days of pregnancy, the puppies will start to move into a birthing position in the mother’s birth canal after almost fully developing. As the mother approaches this stage, she will likely become restless, pant, pace, and lose her appetite. It is also common for their body temperature to drop in the hours leading up to labor.

A good idea is to prepare a maternity box for your dog so that when she delivers her puppies, she will have something to place them in. To give your pregnant dog a place to nest during the time of her pregnancy, line a comfortable box with soft blankets or soft bedding. When she expects to give birth, she will be able to go to this area to get ready for the birth process.


The behavior of your pregnant dog is likely to change during labor, as she will become restless and will refuse to eat. Afterward, the puppies will be born. It is possible for labor to last for several hours to several days. However, it shouldn’t last more than 24 hours. Every half hour or so, puppies should appear one at a time, but no longer than two hours at a time.
