Dad chases down and kills vicious dog that jumped on son, 3, and bit his face in street

A dad saved his young son from a vicious dog attack in the street - before chasing down the animal and killing it.



Horror CCTV footage shows Lu Mingze, three, following behind his parents as the trio strolled through their residential complex on a sunny day.



As they walk, the clip shows a dog come into view from nearby bushes.



The canine suddenly pounces on the unsuspecting boy, knocking him to the ground and savaging at his face and head.



The boy's father, Lu Jungeng, ran over and immediately kicked the dog, causing it to stop its attack and run away.
