This three-month-old puppy refused to leave the side of its dead sister after she was hit by a car. The heartbroken dog lay with the female puppy for two days until a kindhearted person buried her.Witnesses in Pixian County, southwest China's Sichuan Province, said they saw two dogs, a grey one and a brown one, lying in the middle of the street.The brown puppy was protecting the body of the grey one from being hit by any passing cars  by jumping up and barking if one got close. They remained in the same place for several days until a person moved them to safety at the side of the road.Another member of the public then dug a hole to bury the grey dog. Even then, its brother jumped into the hole too refusing to leave its companion. Eventually, the brown dog was collected by staff from a local animal protection centre where it is being cared for.(dailymail.co.uk)ANN.Az
