This is the heartwarming moment a smart dog pulled a fallen bag to the roadside to keep it from being trampled by oncoming cars. CCTV footage shows the pooch named Jumbo waiting for cars to pass before retrieving the plastic bag left in the middle of a road in Samut Sakhon province, Thailand, on September 24. The clever canine dragged the bag to the road shoulder, where it was later retrieved by a trio of students who thanked the dog for its help. Onlooker Gift Anutsara said: 'Jumbo is very smart. He knew that the bag would be run over if he didn't put it somewhere safe.'
