I wanted to point out earlier that her being afraid of a bat does not neccesarily mean abuse. My dog will cower when we shoot archery or someone cracks whips, but there's nothing I've done that could give him a bad association there. A lot of animals dont like loud noises until they become accustomed to them.
But as
@tripletfeb said, I'm not there so I'm not saying shes not being abused. Just that it's possible shes not.
She could also have previously been abused and have PTSD or specific triggers even if shes not being abused now.
