How Long Are Dogs Pregnant? Your Complete Guide

On average, dog pregnancy lasts for around 63 days, but the exact length can vary based on a variety of factors such as breed, age, and the number of puppies in the litter. It’s crucial for pet owners to be aware of the signs of impending labor and provide proper care to their pregnant dogs, including good nutrition, regular check-ups, and vaccinations.

In this blog, we explore the different stages of dog pregnancy, the average length of gestation, factors affecting canine pregnancies, and simple tips to care for your pregnant pup!


Understanding Dog Pregnancy

Understanding dog pregnancy is critically important for those who own and care for pregnant dogs. Gestation periods in dogs typically last two or three months, and during that time, owners must be comfortable with the basics of canine prenatal care.

From providing an appropriate diet to monitoring their health to preparing for the delivery process, properly managing a dog’s pregnancy can help ensure the health of both pet and pup.

In many cases, conscientious owners are best able to advocate for the well-being of their beloved pets both during pregnancy and beyond. A little research now can make life much easier—and happier—later.

Stages of Dog Pregnancy

An expectant pup-parent has a lot of questions when it comes to their furry companion’s pregnancy. While each pregnancy is unique, there are generally four distinct stages all pregnant dogs go through, with each stage running for about three weeks.

Stages of Dog Pregnancy

Stages of Dog Pregnancy


  1. Pre-mating: During the pre-mating phase, female dogs will attract males with physical signs such as flirting and increased vocalization. They may also have a rise in temperature to signal they are ready to mate.
  2. Fertilization/Conception: After successful mating, fertilized eggs are implanted in the uterus and conception occurs. This usually takes place within 24 hours of mating, although some embryos may not implant until up to four days later.
  3. Embryonic Stage: During this stage, which lasts about three weeks, the developing puppies grow rapidly in size and begin to form their internal organs.
  4. Fetal Stage: During this stage, which lasts about five weeks, the puppies continue to develop and gain weight. They begin to move around in the uterus and their eyes and ears start to open.
  5. Late Pregnancy: This is the final stage of dog pregnancy, lasting roughly two weeks before delivery occurs. During this time, the puppies are fully formed and ready to be born.
  6. Delivery/Birth: This is when the puppies are expelled from their mother’s uterus and begin their life in the world! After delivery, puppies typically nurse for about eight weeks before they are weaned and able to eat solid food on their own.


Average Length of Dog Pregnancy

Dog pregnancies can range in length depending on the breed and size of the dog, with a normal gestation period lasting anywhere from 58 to 68 days. Most small breeds will be pregnant for an average of 63 days, while larger breeds may stay in heat for up to 72 days.

Each pregnancy comes with its own timeline, so it’s best to consult with your vet to determine how long you can anticipate your dog’s pregnancy to last. Measuring daily changes in body temperature can also help predict when labor is close. A decrease in temperature may indicate that delivery is imminent!

Factors Affecting the Length of Canine Pregnancy

Breeds with Longer and Shorter Pregnancies

When it comes to factors affecting the length of a canine pregnancy, it is important to note the differences between breeds with a longer gestation period than others. Some smaller dogs can carry their puppies for as little as 58 days while larger breeds may have pregnancies that last up to 72 days.

Nutrition plays an important role in determining the length of a dog’s pregnancy. Providing your pet with high-quality food and essential vitamins and minerals will help support hormone levels which are vital in fetal development.

Regular veterinarian visits are also key during this time, allowing you to track progress and monitor puppy growth. Taking these steps will help ensure your pup has a safe, healthy pregnancy.

Age and Health of the Mother Dog

One factor that can affect the length of canine pregnancy is the age and health of the mother dog. Older dogs generally spend a longer time pregnant than younger ones, because their bodies may take more time to grow and deliver puppies. Similarly, if the mother dog is in poor health, her pregnancy may take longer than normal.

Dogs with certain congenital conditions, or who are obese or carrying multiple litters, often experience extended pregnancies as well. The experienced pet owner should stay vigilant and be aware of any potential problems that could arise due to an extended gestation period.

If you suspect your canine’s pregnancy is taking longer than expected, it is important to consult a vet right away.

Number of Puppies in the Litter

Canine pregnancies can be made complicated by a variety of factors, such as the number of puppies in the litter. It has been observed that litters larger than six often take longer for the dog to give birth and have a longer pregnancy overall.

This effect also increases with each additional pup in the litter, and having more than nine puppies in one pregnancy is considered high risk with potentially serious complications.

It’s important to speak to your veterinarian concerning any issues with canine pregnancies, especially when it comes down to the number of pups in the litter.

Physical Changes

As a pet parent witnessing your dog’s delivery is an incredible experience. It can also be nerve-wracking if you are unsure about the signs of imminent delivery. The physical changes that occur in the pregnant dog during this time can be very powerful.

You can expect to notice behavioral, body composition, and general comfort level changes in your dog as she prepares for the puppies’ arrival. With a sound understanding of these physical changes and their implications, you have an opportunity to support your pup through her labor in a safe and informed manner.

  • Swelling of the mammary glands
  • Nesting activities, such as digging and rearranging bedding
  • Restlessness or pacing
  • Loss of appetite
  • Increase in vocalization
  • Abdominal contractions and/or discharge from the vulva

Nesting Behavior

To ensure that the impending delivery of your pregnant dog goes as smoothly and stress-free as possible, one key step is to monitor her nesting behavior. Knowing the signs of imminent delivery can help you to be better prepared and provide additional care and comfort to your dog.

Being aware of these signs can help both you and your pet have a stress-free experience during this special time.

  • Digging or rearranging bedding in the area where she plans to give birth
  • Seeming agitated and unable to relax
  • Moving bedding materials to a secluded, comfortable area
  • Collecting toys, blankets, or other items and bringing them into her chosen nesting area
  • Spending more time sleeping than usual
  • Frequently licking her vulva area
  • Becoming more vocal than normal or exhibiting unusual behavior such as whimpering or whining
  • Pacing in the house or around the nesting area.

Ways to Care for a Pregnant Dog

1. Proper Diet and Exercise Regimen

Proper care of a pregnant dog includes strict monitoring of diet and exercise. It’s important that your pup receives all the essential nutrients she needs in her diet to keep herself and her litter healthy and strong. Your veterinarian can provide you with expert advice about the particular type of food best suited for your dog’s stage of pregnancy.

Exercise should be moderate and based on what is comfortable for the dog but should follow a regular schedule. Getting enough rest is also important. A different sleeping schedule than usual may be adopted as well as extra breaks during walks.

With some dedication and mindfulness, you can ensure your pup has a safe and successful pregnancy.
