Certainly, you may not communicate with a dog in the same language, but that doesn’t mean it doesn’t understand you. Dogs pay attention to verbal and physical signals much more intensely than humans. They can notice certain things earlier. Their ability to perceive subtle cues imperceptible to humans is scientifically proven.

A dog can smell cancer.

Many studies prove that dogs can indeed sense such significant changes in the human body. Their incredible sense of smell allows them to detect the presence of specific substances in human blood.

While not claiming 100% accuracy, dogs have demonstrated impressive abilities in medical detection. In 88% of cases, dogs were able to correctly identify women with breast cancer, and lung cancer detection rates reached as high as 99%. Doctors have also trained dogs to detect ovarian cancer.

Dogs can sense changes in the weather.

This aspect, often considered one of the old legends, has been scientifically proven that dogs are indeed incredibly sensitive to changes in the weather. Researchers attribute this to their ability to perceive changes in barometric pressure. Additionally, they pay attention to humidity and ozone concentration, which change before inclement weather.

One study also demonstrated that dogs are sensitive to static electricity, allowing them to sense the approach of a thunderstorm.

Dogs can sense fear.

It’s hard to imagine that dogs can sense the smell of your blood, but they do have a keen ability to pick up on your emotions. They can sense fear because they are sensitive to the smell of adrenaline, which is released into the blood. Your pet is likely to stay close to you to make you feel more comfortable.

Dogs know that the puppy eyes technique works.

Those pleading eyes—who can resist them? Dogs are aware that you can’t resist, so they use this gaze to their advantage. Scientists have found that when you look at your furry friend, your brain releases oxytocin, a chemical that makes you feel happy.

Your dog experiences a similar brain response, which is why they love to gaze at their owners.

When a dog starts barking at a person you don’t particularly like, it’s not without reason. They sense changes in your body and start to dislike the person in advance. Can you trust someone who isn’t liked by the owner?
