In short, it is their way of greeting. When a puppy is born he/she has two senses, touch and scent. It is impolite (in the dog world) for a dog to greet another with touch (pawing, biting, rubbing (like cats), etc.), so they rely on their second sense, scent. The scent of any animal is strongest in the rear... so that is where dogs sniff.
Senses are by which we experience our surroundings. Sight, hearing, taste, feel, smell. A bark is a sound.
