I'm so sorry, I bet that was very scary for the both of you. But she knows you love her and she knows she is safe with you. She just panicked and it brought back memories. Just her reaction after you freed her tells me that she trusts you completely.

I know this is a sensitive subject and I know there are horrible people out there, I hope you don't mind me asking, but why was she hog tied by her previous owners?

Anyways, she is a beautiful dog and I am so glad you rescued her, and I know she is too. Just give her lots and lots of lovins' and she will be just fine.
