If you encounter any dog at high speed just take it head on instead of swerving. The dog will hit grill bonnet windshield and get tossed in air. If you try to avoid it very soon you will find yourself doing summersalts. One fine night brother was driving back home from office close to zero point a motorcycle wala took an illegal u turn. He was picked late so instead of hitting the brakes and keeping the steering straight my brother just rolled the steering, he avoided the collision but car got destabilised, rear wheels came in contact with divider, tossing the car in air, which came down on its roof. The speed was 60kph at that time imagine what would happen at 120.
