Outtatheblue's got it nailed.
Keep your horse's mind busy and focusing on you. Circles, leg yields, transitions from one gait to another, transitions within gaits, half halts, spiraling circles, teardrops, just about any movemement you can get out of a dressage or equitation pattern will work, or any move you can dream of that your horse will understand.
The point is not to let their peanut brain become fried by every little horse eating monster they think they see.
