Hey it’s a long process. Take it very very slowly but it’s training like anything else. Have her look at the elevator. Treat everytime she looks at it… For days. Take a step closer days later and treat. Eventually go in the elevator but don’t take it, go back out to a safe distance and treat treat treat. Repeat for weeks. Practice the same thing other places with elevators in different environments. Eventually you’ll be fine, but it will take a lot of patience.
