Dogs can detect tiny amounts of smell diluted in air, water or far beneath the ground. According to the Marbach Road Animal Hospital, dogs can pick up scents that are diluted to 1 or 2 parts per trillion; This allows them to smell things buried as far as 40 feet underground! In one experiment, a dog was capable of sniffing out whale poop floating in Puget Sound from a mile away, according to Nova.
But when the dog takes a deep sniff, the air  travels all the way to the smell receptors, near the back of the  dog's snout. So for a dog, sniffing is a big part of smelling.  Generally dogs have an olfactory sense approximately 100,000  to 1,000,000 times more acute than a human's.
