Pigs have an incredible scent sense ability. They are able to smell 50cm (~19 inches) deep into the ground and have the precision to decipher even between types of worms. Their powerful noses are confronted with a plethora of new smells all the time, making them very sensitive to their environments and foods. With more olfactory cells than dogs, pigs would make excellent drug or bomb sniffers, except for the fact that their strong wills make them difficult to order around.
