How can I Tell if my French Bulldog is Pregnant? 10 Pregnancy Signs

How can I Tell if my French Bulldog is Pregnant?

Determining if your French Bulldog is pregnant involves observing various signs and seeking veterinary confirmation. Common indications include a slight increase in appetite, a behavior change (more affectionate or withdrawn), a noticeable increase in weight, and enlarged or darkened nipples. As the pregnancy progresses, you might also notice a swelling belly. However, a visit to the veterinarian is essential for a definitive answer, where tests like ultrasound or blood tests can confirm pregnancy.

10 Early Signs of a French Bulldog Pregnancy

Change in Appetite

Early in pregnancy, a French Bulldog might experience a slight decrease in appetite. However, this can quickly shift to an increased appetite as the pregnancy progresses. These changes are due to hormonal fluctuations and the growing nutritional needs of the developing puppies.

Behavioral Changes

Your French Bulldog might become more affectionate and clingy or withdraw and seek more alone time. These behavioral shifts are often due to hormonal changes and can indicate pregnancy early.

Enlarged or Darkened Nipples

One of the early physical changes you might observe is the darkening of your dog’s nipples. They may also appear more swollen or prominent. This is in preparation for nursing the puppies.

Increased Weight

You might observe a slight weight gain even before her belly grows noticeably larger. This will become more pronounced as the puppies develop, but a subtle increase might be noticed early on.

Mild Fatigue

Your French Bulldog might appear more tired than usual or less eager to play. This lethargy can be attributed to her body’s physical and hormonal changes.

Clear Vaginal Discharge

A clear and odorless vaginal discharge can be noticed in some pregnant dogs. This is a natural part of the pregnancy and should not be confused with an infection or other health concerns.

Slight Abdominal Swelling

As the embryos start to grow, there might be a subtle change in your dog’s abdominal size. This will become more noticeable in the later stages of pregnancy.

Changes in Body Temperature

A dog’s basal body temperature can drop slightly about a day before she goes into labor. Monitoring her temperature can show you where she is in her pregnancy, but this indicates the late stages.

9Nesting Behaviors

Much like humans, a pregnant French Bulldog might exhibit nesting behaviors. This includes gathering toys or blankets and creating a cozy spot, which is an instinctual preparation for the arrival of her puppies.

Reduced Activity

Apart from general fatigue, you might notice that your French Bulldog isn’t as active or playful as before. She might avoid jumping or running, being more cautious due to the changes in her body.

Tests to Confirm French Bulldog Pregnancy


Palpation involves the veterinarian gently feeling the dog’s abdomen to detect the presence of growing puppies. This method is most accurate between the 28th and 35th days of pregnancy. However, it requires an experienced hand to avoid harm to the developing embryos.


An ultrasound can detect a heartbeat and give a visual of the puppies as early as 25 days into the pregnancy. It’s a non-invasive procedure and can also give insights into the embryos’ health and number.

Blood Test

Around 22 to 27 days post-breeding, a blood test can detect the hormone relaxin, produced only during pregnancy. This test offers reliable confirmation but won’t provide information on litter size or the puppies’ health.


Later in the pregnancy (around 45 days or more), an X-ray can confirm the pregnancy and give an approximate count of the number of puppies. It provides a more precise image once the puppies’ bones have calcified.

Hormone Testing

By measuring the levels of certain hormones, like progesterone, veterinarians can estimate the stage of the pregnancy and predict possible whelping dates. However, this method is more commonly used to determine optimal breeding times than to confirm pregnancy.

What Does a Pregnant French Bulldog Look Like?

A pregnant French Bulldog will exhibit noticeable physical changes as her pregnancy progresses. Her abdomen will gradually swell, becoming more rounded and prominent, especially in the last weeks of delivery. The dog’s nipples will also become enlarged and more pronounced and may darken in color in preparation for nursing. Apart from these visible changes, her overall gait might appear more deliberate or cautious, and she might gain weight. However, monitoring her health and consult a veterinarian throughout the pregnancy is essential.

French Bulldog Pregnancy Stages

Days 1-7 Fertilization: During the first week after mating, the sperm fertilizes the eggs in the fallopian tubes. The fertilized eggs then start their journey towards the uterus.

Days 8-14 Implantation: The fertilized eggs continue traveling down to the uterus, where they begin to implant into the uterus lining. The embryos start to develop.

Days 15-28 Early Development: By the third week, the embryos are attached securely to the uterus wall and are now called fetuses. Vital organs begin to form. Around day 25, a vet might be able to detect heartbeats using an ultrasound.

Days 29-35 Mid Development: During this phase, the fetuses grow rapidly, with facial features, limbs, and bones becoming more defined. Their size increases, though they remain pretty small.

Days 36-49 Major Growth: The puppies undergo significant growth during this period. Their skeletal systems continue solidifying, and they look more like miniature dogs. Their facial features, toes, claws, and whiskers become more distinct.

Days 50-58 Final Maturation: Puppies are nearly fully formed by this stage. They develop hair, and their internal organs mature in preparation for birth. The mother might show restlessness as she searches for a suitable place to give birth.

Days 59-63 Pre-Labor to Birth: During these last days, the mother will start showing signs of nesting, often trying to find a quiet and comfortable spot for delivery. Her appetite may decrease, and a slight drop in body temperature indicates that labor is near. By the end of this period, she will go into labor and deliver her puppies.

Can I rely on physical changes to determine if my Frenchie is pregnant?

While physical and behavioral changes can indicate pregnancy, they aren’t definitive proof. Other conditions or factors might lead to similar symptoms. For a conclusive determination, it’s always best to consult a veterinarian, who can provide accurate diagnostics like ultrasounds or blood tests.
