Special cells help with smelling
The olfactory or smell receptors are located within special sniffing cells called ethmoidal cells. These are found deep in a dog's snout in structures called turbinates.
In one experiment, a line of 12 men followed each other, stepping in each other's footprints. After walking for a distance, each man went left or right to hide. The dog was then asked to find its owner who was the first man in the line of 12. The dog had no problem finding its owner's scent, even though it had been mixed with that of 11 other people.
