Did you know!
A dog’s sense of smell is about 1,000 to 10,000,000 times more sensitive than a human’s (depending on the breed).
They can smell a small sent from dogs to other species that is unrecognisable to humans.
Rescue dogs can track down a sent that maybe months old.
Dogs also have a universal sense which humans do not have, where they can feel the energy (emotions) of the other beings around them.
The olfactory (smell) communication is important in all species, the vomeronasal organ (also called Jacobson’s organ) is located in the roof of the mouth.
With this organ they can smell pheromones, they can tell a lot about another dog or human including if they are male or female, what they ate, where they have been, what they have touched (this is way your dog rushes to smell you after being away), if they are ready to mate, if they have recently given birth, or had a false pregnancy, and what mood they are in (this is why dogs are great comforts when their owners are sad or ill).
