Dog protected abandoned newborn
(CNN) -- A dog sheltered a newborn baby abandoned by its 14-year-old mother in a field in rural Argentina until the boy was rescued, a doctor said Friday.
A resident of a rural area outside La Plata called police late Wednesday night to say that he had heard the baby crying in a field behind his house.
The man went outside and found the infant lying beside the dog and its six newborn puppies.
The dog had apparently carried the baby some 50 meters from where his mother had abandoned him to where the puppies were huddled
"The dog is a hero to us."
参考答案：
一个医生在星期五说有一只狗保护了一个被只有14岁的母亲遗弃在阿根廷乡下的田野里的刚出生的婴儿直到他被救。
上个星期三晚上一个住在拉普拉塔外乡下的居民报警说他听到他家房子后面的田野里有婴儿啼哭的声音。
这个男人走出去发现了一个刚出生的婴儿和六只刚出生的小狗躺在一只狗的旁边。
显然这个狗从50公里外的他母亲遗弃他的地方把这个孩子带来和小狗放在一起。
对我们来说这只狗就是个英雄。
