As a dog owner, there's nothing more exciting than anticipating the arrival of new puppies. But how do you know if your female dog is pregnant in the first place? A female dog can become pregnant as early as 8-10 weeks after her last heat cycle.
One of the earliest signs of pregnancy is a slight increase in appetite, which can be a good indication that your dog's body is producing more milk for the developing puppies.
As the pregnancy progresses, you may notice a slight swelling in your dog's abdomen, which can be a sign that the puppies are growing and developing.
A veterinarian can confirm pregnancy through a physical exam and a blood test, typically between 25-30 days of gestation.

What Are the Signs?
Your dog's pregnancy can be a wonderful experience, but it's essential to know the signs to provide the right care. A dog's pregnancy lasts up to 68 days, and understanding the timeline can help you prepare.

Some dogs may show a slight increase in appetite early on, while others may vomit due to hormonal changes. Be aware that this can be a sign of pregnancy, but it can also be caused by other conditions, so it's always best to consult with a vet.
As the pregnancy progresses, you may notice a swollen belly, which can start to show around day 40. However, some dogs may not show as much, especially first-time mothers or those carrying a small litter.
Here are some signs to look out for:
- A slight mucus discharge may occur around one month after mating.
- Her teats may become more prominent in colour and size around 30 days after mating, and you may also see them produce a semi-clear fluid.
- She may vomit a little in the early stages of pregnancy, similar to morning sickness.
- She will start to gain weight from around day 35 of her pregnancy, which will gradually increase by up to 50% above normal.
- She may act a little quieter than usual, or her appetite might drop.
- Her appetite will increase in the second half of pregnancy, so be prepared to change her diet accordingly.
Keep in mind that some of these signs can be non-specific and may indicate other health issues, so it's crucial to consult with a vet for an accurate diagnosis.
Confirming Pregnancy
Home pregnancy tests designed for dogs can detect pregnancy hormones in your dog's urine, but they're not the most reliable option. The relaxin hormone they test for is only detectable from 30 to 35 days into the pregnancy.
Suggestion: Female Dog Phantom Pregnancy
Veterinarians can test for the hormone relaxin to determine if a dog is pregnant, but the test must be taken at least 30 days into the gestation period for it to be accurate.
An ultrasound examination is a more reliable way to confirm pregnancy, typically performed around the 28th day after breeding.
Home Tests
Home tests can be a convenient way to confirm pregnancy, but it's essential to understand their limitations. Home pregnancy tests designed for dogs can detect pregnancy hormones in your dog's urine, but they may not work for very small litters.
The relaxin hormone these tests look for isn't detectable until a dog is more than halfway through the pregnancy, at 30 to 35 days. This means the test may not give accurate results if you take it too early.

Ultrasonography or X-Rays
A veterinarian can perform an ultrasound examination to confirm pregnancy, typically around the 28th day after breeding.
An ultrasound can provide valuable information, but it may not be enough to determine the number of fetuses present.
The best way to determine how many fetuses are present is through an X-ray, which can typically reveal fetal skeletons around the 45th day of pregnancy.
This information will help you prepare for the birth and ensure you're ready for the arrival of your new puppies.
Palpation
Palpation is the cheapest and most convenient way to diagnose pregnancy.
A veterinarian can perform an abdominal palpation 21 to 30 days into gestation, and may be able to feel an enlarged uterus or multiple swellings within it.
Feeling an enlarged uterus is not a definitive way to diagnose a pregnancy, as it may be mistaken for organ enlargement, infection in the uterus called pyometra, or tumors.
The membranes around each fetus grow to form fluid-filled sacs that can be felt between days 21 and 35 of gestation.

These sacs can grow to about the size of a table tennis ball in a 45-pound dog, but after one month, they lose their distinctive shape.
Only a veterinarian should do an abdominal palpation to avoid causing your dog or her puppies any harm.
You should never attempt to perform abdominal palpation yourself, as you could harm the puppies.
Hormone Tests
Hormone Tests can be a reliable way to confirm a pregnancy in dogs. Veterinarians can test for the hormone relaxin to determine if a bitch is pregnant, and this hormone is released from placental tissue only during pregnancy.
Relaxin is detectable around 30 days into the gestation period, making it a fairly accurate diagnostic test. However, tests taken before that can have a false negative.
A positive test result doesn't necessarily mean the dog is pregnant, but rather that the hormone relaxin is present. This is why it's essential to consult with your veterinarian for recommendations on the best options and to ensure you're performing the test correctly.
Veterinarian Visits
Confirming Pregnancy is an exciting time for any dog owner, but it's essential to have a plan in place for the health and well-being of both mom and puppies.
Your veterinarian will recommend a prenatal checkup before breeding your dog, ensuring she's up-to-date on vaccinations.
Regular visits to the veterinarian are advised during the gestation period, and it's best to have a plan established well ahead of time in case an emergency arises.
Your vet will examine your dog in detail and get her previous reproductive history to determine anything that may hinder a normal whelped litter.
The veterinarian will advise on the best method of delivery, which may include an elective cesarean for certain breeds.
Most veterinarians will recommend deworming your dog before pregnancy, around 40 to 45 days of gestation, and regularly while nursing puppies.
This is also a good time to discuss taking precautions in the future, such as spaying, to prevent unplanned litters if the pregnancy was an accident.

Pregnancy Stages
A dog's pregnancy typically lasts around 68 days, but understanding the progression of pregnancy can help you provide the right care for your dog.
Here's a rough breakdown of the pregnancy stages:
- Month One: Early signs of pregnancy may include increased appetite, weight gain, and behavioral changes.
- Month Two: By day 50, an x-ray will reveal the number of puppies in the litter, and the bitch will start looking for a place to nest at day 58.
- Month Three: The bitch is ready to whelp by the start of the third month, and symptoms during the last few days of pregnancy include appetite loss and a drop in body temperature.
Stage Three
Labor can be a long and tiring process, and it's essential to monitor your dog's progress closely. If your dog's labor takes more than 24 hours, or if more than 2 hours pass in between puppies, contact your veterinarian immediately, as this could be a sign of a serious complication.
Prolonged labor can put the lives of both your dog and her unborn puppies at risk. Your veterinarian can provide guidance on how to help your dog through this process and ensure the health of her puppies.
If you're experiencing any concerns or questions about your dog's pregnancy or labor, it's always best to consult with a veterinarian for personalized advice.
Month Three
Month Three is a critical time in the pregnancy of a dog. By the start of the third month, the bitch is ready to whelp.
Suggestion: 4 Month Old Shiba Inu

The development of the puppies is almost complete around day 58, which means they will begin to move into the birth canal over the last few days of the bitch's pregnancy.
One of the first signs you might notice is a trimming of the waist as the puppies move into position. This is a normal and natural part of the whelping process.
Appetite loss is another symptom that can occur around day 61 or 62. This is because the bitch is preparing for labor and may not feel like eating.
A drop in body temperature can occur 12-to-24 hours before labor, which is a sign that the bitch is getting ready to give birth.
You may also notice restless behavior in the bitch, such as pacing, panting, shivering, or digging. These are all normal behaviors that indicate the bitch is preparing for labor.
Here are the common symptoms you might notice during the last few days of pregnancy in dogs:
- Waist will trim as puppies move into the birth canal
- Appetite loss around day 61 or 62
- Drop in body temperature 12-to-24 hours before labor
- Restless behavior
- Pacing, panting, shivering, or digging
Caring for a Pregnant Dog
Caring for a pregnant dog is crucial to ensure the health and well-being of both mom and her puppies. Proper nutrition is essential, and if your dog is already on a good quality dog food and is at a healthy weight, you won't have to make any changes to her diet for the first two-thirds of her pregnancy.
You should gradually increase her food intake as her weight increases in the last weeks of her pregnancy, until she consumes 35-to-50 percent more than usual. It's best to feed her small, frequent meals to avoid discomfort.
Exercise should not be strenuous, especially during the first two weeks of pregnancy, and you should limit strenuous exercise during this period to enhance the implantation of the embryos.

Proper Nutrition
Your pregnant dog needs proper nutrition to stay healthy throughout her pregnancy. This means providing high-quality, balanced meals formulated to provide all the nutrients pregnant dogs need.
Unless your veterinarian advises otherwise, you won't need to make any changes to your dog's diet for the first two-thirds of her pregnancy if she's already eating good quality dog food and is at a healthy weight.
Increasing food intake too early can be harmful, so it's essential to wait until her weight increases in the last weeks of pregnancy. At this stage, veterinarians recommend increasing her food intake gradually, until she consumes 35-to-50 percent more than usual.
Feed your dog small, frequent meals throughout the day to avoid discomfort, rather than giving her single large quantities. This will help her digest her food better and maintain her energy levels.
Your veterinarian will be the best guide when it comes to specific dietary recommendations and advice, including foods dogs shouldn't eat. Be sure to consult with them for personalized guidance on caring for your pregnant dog's nutritional needs.

Comfortable Nesting Area
Creating a comfortable nesting area for your pregnant dog is crucial for a safe and healthy delivery.
Provide a quiet space free from regular foot traffic or doors.
Furnish the area with soft bedding for your dog.
Exercise
Exercise should be gentle and controlled for a pregnant dog, especially during the first two weeks of pregnancy. After the initial two weeks, normal but gentle exercise can resume until the dog's belly begins to enlarge.
Strenuous exercise should be avoided during the first two weeks of gestation to enhance the implantation of the embryos. This allows the fertilized eggs to settle properly in the uterus.
During the last trimester, shorter and possibly more frequent walks will be more beneficial for the mother-to-be. This helps her conserve energy to carry the pups and give them the nutrition they need.
Limit exercise to indoors only as birthing nears, to prevent exposure to diseases that may be detrimental to her and the puppy's health. This also limits her exposure to canine herpes, a condition that can lead to still-born puppies.

Preparing for Puppies
As the end of your dog's pregnancy approaches, you'll notice a significant enlargement of her breasts and nipples, and might even detect some milky fluid as the milk glands develop and enlarge.
Her abdomen will increase in size and may sway a little as she walks, and at the very end of the pregnancy, you might even be able to see or feel the puppies moving around inside the mother.
You want to prepare yourself and your dog for whelping, or puppy birthing, by setting up a whelping box. A whelping box offers a safe, warm, draft-free, easily cleaned location for your dog to have her puppies.
Whelping boxes can be purchased or you can even use a small children's plastic swimming pool. The whelping box should be easy for the mother, but not the puppies, to get in and out of.
Your dog may prefer to have it in a quiet area of the house but in an area that you can have easy access.
Here are some essential items to have in your whelping box:
- Lots of newspaper to line the whelping box during delivery for easy cleanup and garbage bags
- Non-skid bath mats for bedding after whelping is done
- Dry, clean towels to clean the puppies
- Paper towels to help with clean up
It's also a good idea to have a thermometer to check your dog's temperature before whelping, and to have a veterinarian's phone number and the number of a nearby emergency clinic handy.

Labor and Delivery
Labor and delivery can be a stressful time for dog owners, but knowing what to expect can help. The warning signs of labor include a drop in rectal temperature, usually 8-to-24 hours before delivery, and a decrease in appetite.
Pregnant dogs may start to pant heavily and build a "nest" in the whelping box. Abdominal contractions may begin slowly and gain strength and frequency, accompanied by straining and moaning.
You may see the water sac come out when there's a puppy in the birth canal, and within one hour the first puppy should be delivered. Each puppy is born enclosed in its placental membrane and needs to be licked and cleaned by the mother, or by you if necessary.
The mother should sever the umbilical cord as she cleans her pups, but if she doesn't, you'll need to snip the cord and tie it off with dental floss. You should also wipe the abdomen of all the puppies with iodine to prevent infection.

Some dogs deliver their puppies one right after another, but others may deliver a few puppies and then rest before delivering more. If there's a break of more than two hours, you'll want to call your veterinarian.
The entire duration of a normal whelping is about equal to the number of puppies in utero, so a litter of 6 should normally take about 6 hours total. It's essential to keep track of the number of placentas, as a retained placenta can cause problems for the mother.
Offer the mother water to drink and take her outside to relieve herself if she's in the middle of having a large litter. Keep an eye on the pups to make sure they're all breathing normally and nursing within a few hours.
