Smelling is a dog’s number one sense.  They always have their nose to the ground.  In comparison to humans, they have 44 times more scent receptors.  That’s an amazing nose!  That is why dogs are so valued to search for bombs, narcotics, or people.  The dogs that are known to have the best sniffers are scent hounds such as blood hounds, basset hounds and beagles.
