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?
From what I have been told, they would hog tie her and see how long it took her to free her self. Then after she would free her self she was allowed to eat. I don't know what sick people would ever want to do this to her, but they need it done to them to see how she felt/feels.

She goes nuts with shoe strings, she is trying to free us, but she gets a little carried away at times. She is a great dog and I love her more than anything. I can under stand that she panicked. She is such a sweet girl though.
