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