We have palm trees out the front when the wind blows alot she'll sit at the door and get a bit weird.
The loud noises are the main concern though. I leave the front door open so she can investigate things she hears outside. When the bin man comes she can hear the truck and she runs around the house and out the back and around the yard then back inside. I casually go to the door, look out and she'll look from afar but won't get too close.
Thanks Paganman
