A fearful horse may take 20 to 50 repetitions before accepting any strange or new stimulus, while a braver horse might only take five to 10 encounters. The duration of the process really depends on the horse. Horses are also rapid learners and desensitize very quickly to frightening stimuli.
Desensitize your horse’s entire body – over, under, in front, and behind. To do this, rub his whole body with different objects, and allow him to hear all the different sounds they make. Start with an inflatable toy, then graduate to grocery bags, garbage bags, and tarps.

If you’re nervous, tense or unnerved, you can’t help a spooky horse. … If you give the horse his head to explore; relax; sit back; and calm down, he’s less likely to react and you’re in a better position to over his center of balance (and comfortable in yours) to stay with him if he does.
The added height and visibility that the horses give their riders allows officers to observe a wider area, but it also allows people in the wider area to see the officers, which helps deter crime and helps people find officers when they need them.
The phrase “sack out” also refers to going to sleep. Sacking out is a method used by horse trainers to desensitize a horse to potentially frightening situations or objects.
