From VeterinaryPartner.com, here's a way to help your pup over this:

Vacuum cleaners make weird noises. Their use involves a person thrusting the thing around the room in gestures that wouldn't make any sense to a dog. The concept of cleaning a floor, other than by eating any food spilled on it, would also be foreign to a dog's way of thinking. There's not much about a vacuum cleaner for a dog to like! The occasional herding dog will chase it because it moves, and some dogs will "attack" or threaten it because it isn't acting right!

Adding treats to vacuuming time can work through this fear. If the dog is really traumatized about the device, you may need to start with setting up the vacuum cleaner and giving the dog treats in the next room. Over several sessions you can move the treat-giving closer, never faster than the dog's comfort level can handle. Do the process with the vacuum off, next with the vacuum cleaner running, and finally with the vacuum cleaner moving. While going through this program, put the dog in a different place whenever you vacuum so as not to undo all the good conditioning by scaring the dog again.
