Can dogs truly smell human emotions?

Yes, dogs can truly smell human emotions. Research indicates dogs can detect fear and stress through scent, identifying chemical changes in human sweat and breath. Studies have shown dogs can differentiate between a person's "happy" and "sad" scents, reacting with different behaviors. While we can't assign an "IQ score" to their olfactory abilities, their sense of smell is estimated to be 10,000 to 100,000 times more acute than humans'. This incredible ability allows them to pick up on subtle emotional cues we might miss.
