Woman's best friend: Tests have proved what many have long suspected - that dogs are deeply attuned to human's emotions。

　　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。

　　They believe dogs naturally seek to reassure humans in distress。

　　In tests, when either their owner or a stranger started crying, most dogs approached them providing reassurance and comfort。

　　据英国《每日邮报》报道，大多数养狗的主人都有这样的经历，他们情绪低落时，这个四条腿的朋友就会马上用鼻子在主人周围蹭来蹭去，给他们提供安抚。不过，科学家指出，狗与陌生人也有这种与生俱来的情感共鸣。

　　科学家认为，狗天生会帮助人类消除悲伤。

　　经过试验，不管是狗的主人还是陌生人开始哭泣时，大部分的狗都会靠近他们，带去安慰。
