Dogs and Early Pregnancy: Can They Sense It?

Dogs are amazing animals that can provide comfort, loyalty, and protection to their owners. They are known for their impressive sense of smell, which makes them useful for various tasks such as detecting bombs, narcotics, and even certain diseases.

One of the most astonishing abilities of dogs is that they can sense early pregnancy in humans. In this article, we will explore how dogs can detect pregnancy, the factors that affect their ability to do so, and what it means for dog owners.

Can Dogs Sense Early Pregnancy? Dogs have a keen sense of smell that enables them to detect and interpret the various scents in their environment.

They can detect the slightest changes in odor, which makes them effective at tracking down prey, identifying substances, and even detecting medical conditions. When it comes to pregnancy, dogs can sense the hormonal changes that occur in a woman’s body early on.

The primary hormones released during pregnancy are estrogen, progesterone, and human chorionic gonadotropin (hCG). hCG is only present in pregnant women, making it an essential hormone for detecting pregnancy.

Dogs can detect hCG, among other hormones, through their sense of smell, which is up to 100,000 times more sensitive than that of humans. Therefore, when a woman becomes pregnant, her body will emit a different odor that dogs can pick up on.

Observing Changes in the Environment

Dogs are highly observant animals that pay attention to their surroundings. They are quick to pick up on any changes in their environment, which could be a sign of danger, a change in routine, or a new family member.

Therefore, dogs may notice when their owner is pregnant even before the woman realizes it herself. For example, a dog may notice the changes in mood or routine that occur during early pregnancy.

Pregnancy can cause mood swings, fatigue, and nausea, which can change a person’s behavior. Dogs are perceptive animals and can pick up on these changes in their owner’s behavior.

They may become more protective, affectionate, or worried about their owner’s well-being. Similarly, changes in routine, such as more frequent naps, early bedtimes, or different eating habits, can be noticed by the dog.

Different Dogs React Differently to Pregnancy

Not all dogs have the same ability to sense pregnancy, and even those who can may react differently. Some dogs are naturally more observant or intuitive, while others may be trained to detect illnesses or perform specific tasks.

Therefore, the way a dog reacts to pregnancy may depend on various factors, including breed, temperament, training, and past experiences. Some dogs may become more protective or territorial when a woman is pregnant, while others may show little or no reaction.

Some dogs may become more affectionate, staying close to their owner at all times, while others may become more distant. However, it is worth noting that while dogs can sense early pregnancy, they are not medical professionals and cannot provide a diagnosis.

How Do Dogs Sense Early Pregnancy? There is no scientific evidence to prove that dogs can sense pregnancy with absolute accuracy.

However, many dog owners report their pets’ ability to detect pregnancy with remarkable accuracy. Some say that their dogs can detect pregnancy as early as a week or two after conception.

This makes the topic a subject of much debate among scientists and dog owners alike. One possible explanation for how dogs sense pregnancy is through changes in behavior.

As mentioned earlier, pregnancy can cause mood swings, fatigue, and nausea, which may alter a person’s behavior. Dogs who are familiar with their owners’ routines may notice these changes and become more attentive.

For example, if their owner goes to bed earlier than usual or takes naps more frequently, the dog may sense something is different. Another possible explanation is that dogs can detect subtle changes in odor that occur during early pregnancy.

Pregnant women emit different pheromones, which can be detected by dogs with their sensitive sense of smell. For some dogs, this may be enough to signal that something unusual is happening with their owner.

Finally, it is possible that dogs can sense early pregnancy through training and experience. Some medical detection dogs are trained to detect specific illnesses or substances and may be capable of detecting hormone changes that occur during pregnancy.

Similarly, dogs may have had past experiences with pregnant women that allow them to recognize certain cues.


In conclusion, dogs are remarkable animals that have the ability to sense early pregnancy through their keen sense of smell and their observation skills. However, not all dogs are equally able to detect pregnancy, and those who can may react differently depending on various factors, including breed, temperament, and training.

While there is no scientific evidence to support the claim that dogs can accurately sense pregnancy, many dog owners report their pets’ remarkable accuracy. Therefore, while dogs may not be medical professionals, they may be able to provide comfort, protection, and companionship to pregnant women.

Dogs have an incredible ability to form strong bonds with their owners, who often regard them as part of the family. Therefore, it is not uncommon for dogs to sense early pregnancy in women and react accordingly.

In this article expansion, we will explore some personal experiences of dogs and early pregnancy, specifically, the behavior of a Labrador-cross during labor.

Labrador-cross Behavior During Labor

Jessica, 28, had always been an animal lover and had a furry friend before she even met her husband. When she found out she was pregnant with her first child, she was thrilled but also a little apprehensive about how her beloved Labrador-cross, Max, would react to the changes.

However, Jessica soon found out that she had nothing to worry about. Max was loving, affectionate, and his sense of smell was on point.

Jessica was going through a particularly difficult labor. Although her husband was present, it was Max who provided the most comfort.

Max stayed by Jessica’s side throughout the entire birthing process, pressing his nose against her hand, as if to say, “I’m here for you.”

Max never left Jessica’s room for the three days they stayed in the hospital. He was always there, watching over her and her newborn son.

When it was time for Jessica to leave the hospital, Max was the first one out the door, eagerly leading the way home. Jessica described Max as a “gentle giant” and a “good boy” who knew how to comfort his owner during even the most challenging moments.

Personal Experiences of Dogs and Early Pregnancy

Jessica’s story is not unique. Many dog owners report similar personal experiences of dogs and early pregnancy.

Dogs can sense the high levels of progesterone and relaxin that occur during pregnancy, which lead to a more relaxed, calm demeanor in their owners. They also detect the pheromones and smells that indicate early pregnancy, which might make them more intuitive and attuned to their owners’ needs.

Some dogs are particularly sensitive and tend to cling to their owners more when they are pregnant. They become more protective and watchful and may even display behavioral changes like licking, pawing, or whimpering.

Other dogs may act more indifferent and may not display any significant changes in behavior. However, when it comes to the labor and delivery process, dogs can make all the difference.

Many women report that their dogs have been essential during childbirth. Dogs provide emotional support, comfort, and companionship to their owners during what can be a challenging and traumatic experience.

One way that dogs provide support is by being physically present during childbirth. They can be an excellent distraction from the pain and anxiety associated with labor.

Many dogs who are present during childbirth are well-behaved and instinctively attuned to their owner’s needs. Some have been known to lick their owners, lean on them, or snuggle up next to them during contractions.

Another way that dogs provide support is through their sense of smell. Dogs have an extremely sensitive sense of smell that allows them to pick up on the subtlest of changes.

During childbirth, their sense of smell can come in handy. They can detect changes in body temperature, heart rate, and other subtle changes that could indicate labor is imminent.

They can also detect when their owner is feeling anxious or upset, and use their intuition to provide comfort.


In conclusion, dogs and early pregnancy go hand in hand. Many dog owners report personal experiences of their furry friends sensing early pregnancy and reacting accordingly.

Although the scientific evidence supporting dogs’ ability to sense pregnancy is limited, many people believe that dogs can detect and react to early pregnancy based on their behavior and observations. When it comes to labor and delivery, dogs can provide much-needed comfort, support, and distraction for their owners.

Overall, dogs truly are man’s best friend, a loyal and loving companion that always has their owner’s back. In conclusion, dogs have the ability to sense early pregnancy through their keen sense of smell and keen observation skills.

They can detect the hormonal changes that occur in a woman’s body and respond with protectiveness, intuition and affection. While there is no scientific evidence to support the claim that dogs can accurately detect pregnancy, many dog owners have reported their remarkable accuracy.

During labor and delivery, dogs can provide much-needed emotional support and comfort. Therefore, dogs should be viewed as an essential component of family and their reactions to pregnancy should be considered just like any other family member’s.

Ultimately, dogs can make a profound difference during these crucial moments.
