Understanding Dogs' Sense of Smell and Emotional Detection

The video explores whether dogs can smell fear and how they react to it. Dogs have an extraordinary sense of smell, with up to 300 million olfactory receptors. They use not only their noses but also body language and vocalizations to communicate.
