If there are any "holes," the safe time and place to start changing the conversation, thoughts, and behaviors are not under the pressure of an event that is out of your control. Improving the trust and support in the partnership long before the day of unexpected events allows for less traumatic scenarios for both humans and horses.
Here are a few ideas:
Haltering- Go out to the pasture or stall to halter your horse, call them over, and when you'd normally put the halter on, stop, and leave. Then come back a while later and actually halter them.
Walking out the gate- Change out the direction, body position or breaking down down the way you "always" go out the gate.
Leading- Do so from the horse's off (right) side, or from a distance farther ahead or behind than you normally do.
Tacking- Do things out of order, such as bridle first, then the saddle, and then cleaning hooves.
Mounting- Different locations, different side or perhaps get on and off several times throughout the ride.
Riding off- go to a different spot to warm up, change the direction of the warm-up.
Riding home- head towards home and then turn back as if heading out again, perhaps several times.
