Wrong. Slow down until you get to it then roll on the throttle. Messes up the dogs line of attack.
well my instructor said that if a rodent or small dog like a chihuahua is in your way on the road, that you should "prepare to surmount the obstacle" because if you try to swerve you're putting yourself in danger
but yeah if a dog runs at you from the side you do that to mess it up
