As most dog owners will confirm , a four-legged friend is quick to offer a reassuring nuzzle when you are feeling down and low . But its natural empathy also extends to strangers , scientists claim , the daily mail reported .
Rat pups born to mothers that lick and nuzzle them - even rats that are put in the " foster " care of such mothers - are healthier , grow faster , and are better able to run mazes and interact socially than pups that are neglected .
