How powerful is the smell of a dog?

Humans have about six million olfactory receptors, while dogs own 300 million. We inhale once a second and a half; they five to ten times. They have a superior smell.

In addition, as they exhale from the sides of the muzzle, they are all the time inhaling, which gives them another perspective of smells.

Their sensitivity is such that they can recognize virtually any smell and even diseases

His smell is directly related to the brain. And this relationship is so powerful that it allows them to identify the mood of other dogs that approach them. And communicate. By moving the tail, they spread aromas of the anal glands and thus transmit and salute their state to others.

That is why it is essential that dogs go out for a walk and smell the world around them.
