This can be explained as-

• The olfactory membrane – It is a thick yellow structure, that consists of about one hundred million smell receptor cells. Which is responsible for the sense of smell.

• The human nose has only three square centimeters of the olfactory membrane. Where if we take only for an example  one breed like bloodhound which has about 150 centimeters of the same.
Jacobson’s Organ – A particular organ which we human does not possess. This organ is located at the bottom of the dog’s nasal passage.This organ helps the dog’s nose to pick important cues which in turn are the signal messages for other dogs like mating, readiness etc.
