Why do dogs lick human feet?

Answer:

Answer

it has to do with the salt content of human sweat. when a human sweats through their foot, the invisible salt particles accumulate on the surface of the skin. the dog, not caring or knowing any different, detects trace amounts of salt on the foot, and attempts to retreive it. animals will often try to consume salt or salty products as a way to keep their bodies hydrated, since salt decreases the amount of moisture released from the body.
