Dog hit twice by two separate cars, makes miraculous recovery

Jack was hit by two different cars in one day. The first car wasn't able to avoid him, sending him flying across the road. Jack was left helpless in the middle of the highway, unable to move. The second vehicle hit him from a different angle but somehow didn't manage to kill him. People jumped across the fence, putting their own life in danger, and managed to get him out of the road before he was hit again. This is his incredible story.
