What is olfaction?
Olfaction is the sense of smell.
Olfaction is a chemoreception that forms the sense of smell.
In most animals, olfaction occurs in the nose through holes called nostrils.
Some animals, such as snakes, have a vomeronasal organ located between the nose and mouth that is used to smell prey. Snakes stick out their tongue and then touch it to the vomeronasal organ.

Dogs have a lot more nerve cells in their nasal (nose) cavities (their nostrils) than humans do. Dogs also have and a wider variety of receptors that attract odour molecules.
A research team led by Brent Craven of Pennsylvania State University in University Park in 2008 has shown that dogs can sort smells into categories before the information gets to their brains. The brain then identifies the smell.
