Why do dogs act differently around pregnant women?

Our furry friends are known for their incredible sense of smell, millions of times more acute than ours. This exceptional ability allows them to pick up on subtle changes in their environment, and a pregnant woman’s body undergoes a symphony of hormonal shifts that a dog’s nose can detect.

So, it’s no surprise that some dogs exhibit altered behaviour around expecting owners. Here’s a deeper look at what might be going on:

Scent Detectives Around Pregnant Women:

A dog’s primary way of understanding the world is through scent. Pregnancy triggers hormonal changes that alter a woman’s body odour. These subtle shifts, while undetectable to humans, might be quite noticeable to a dog.

A Range of Reactions in Dogs to Pregnant Women:

Dogs can react to these changes in a variety of ways. Some may become more protective or clingy, staying close to your side as if guarding you. Others might exhibit signs of anxiety, such as pacing or whimpering, around pregnant women. Affectionate behaviour like increased head-nuzzling or licking could also be a response to hormonal changes.

Beyond Scent: Other Factors Affecting Dog Behaviour:

It’s important to consider other factors beyond scent that might influence a dog’s behaviour around pregnant women. Pregnant women often experience changes in routine, energy levels, and emotional state. A dog who is sensitive to these shifts might adjust their behaviour accordingly.

Building a Bond with Your Dog During Pregnancy

While some behavioural changes are natural, any significant alterations, especially those that seem negative or disruptive, warrant a visit to the vet. They can rule out any underlying medical issues and provide guidance on addressing behavioural changes in dogs around pregnant women.


Understanding your dog’s personality and baseline behaviour is key. If you notice any significant shifts, consult your vet to ensure everything is okay. With a little extra patience and attention, you can navigate this special time and maintain a strong bond with your furry companion.
