Dogs Detect Sounds via Scent: Unveiling Their Unique He

Dogs primarily rely on their sense of smell, followed by sight and hearing, and finally, taste. Their olfactory prowess is remarkable; they use it to navigate their world, much like we use our eyes to observe our surroundings. Whether it's a handsome man or a beautiful woman, the attire they wear—be it a skirt or trousers—all these details are crucial to them. For dogs, these are vital pieces of information.

Humans have approximately 500 million olfactory receptors, whereas dogs possess around 300 million. The olfactory mucosa in dogs covers about 150 square centimeters, compared to just 5 square centimeters in humans. Imagine the difference between a newspaper and a postage stamp—it's a stark illustration of their olfactory capabilities. Trained working dogs can even detect certain diseases, warning of epilepsy, high or low blood sugar, and even certain types of cancer. Studies have shown that by sniffing samples of human breath, urine, or feces, dogs can identify patients with ovarian, lung, bladder, colon, or breast cancer with a success rate over 90%.

Through the Scent of the World

While we open our eyes to see the world, dogs rely on their noses. Sometimes, we may be deceived by a smile, but dogs can detect the tension and the increased heart rate that comes with it, allowing them to interpret emotions and thoughts. This perfectly validates the adage, "What you see may not be what is real."

Greeting Through Scent

When we meet someone we like in a particular setting, whether through a handshake or a hug, if a dog approaches, it can quickly identify the person by scent. It can analyze their gender, age, and even where they are from and where they are going.

Listening to the Sound of Life Through Scent

Many dog owners can relate to this experience: when we return home to a chaotic scene, we're about to lose our temper, only to find our dog already settled on the side. This is because our emotional fluctuations, along with changes in our body temperature, heart rate, and breathing, are transmitted through the air and detected by our dogs.

Memory Through Scent

The saying "Keep a dog for three days, and they'll remember you for three years" underscores the loyalty of dogs. Even if they've only been with you for a short time or have only been fed a few times, they will remember. This is why dogs can find their way home after leaving, guided by the scent that brings them comfort. Their sense of smell is their primary form of memory, and the scents of their owners and their clothing can help them remember quickly.
