By the river, a child's ball rolled into the water, and the child chased after the ball, preparing to walk into the river, which was extremely dangerous. This scene was spotted by a stray dog, so the little stray dog quickly ran over and dragged the child away from the riverbank. At this moment, when the child saw a big dog, she was immediately terrified and began to cry. The mother, who was working in the field in the distance, heard the child's crying and saw a big dog next to the child, so she hurriedly ran over, beating and kicking the stray dog until it ran away.
