Can your dog identify you just by your smell?
Dogs cannot only identify us by smell, they seem to like the smell of their human best – so there you have it. You are their MOST favourite smelly thing.
While we humans identify people by their appearance, dogs rely more on their sense of smell. In an early fMRI study, dogs were presented with five scents:
(1) their owner
(2) an unfamiliar person
(3) another dog in their house (4) an unfamiliar dog
(5) their own scent
Human scents were obtained from underarm pit samples and dog scents from the area that dogs like to smell—their butts.
Although it was expected findings would show the strongest response to be the smell of other dogs, in fact we found that the scent of the owner elicited the greatest activation in the reward system of the dog’s brain.
