Remember I am not there to see dog and you can judge better than I can. I can understand your worries and there are other things to try but I believe the longer she is with you and surrounded by your family it will work out.(unless the abuse idiot was beating her with a crate) Good luckThanks Wvasko. I guess the reason I have hesitated to do that (which is what I did with our other dog when he went through this) is that she was rescued from a pretty bad, abusive situation. So we're working on building her trust in us. Physically "making" her do something tends to cause her to shy away and shut down. That's why I was looking for an alternative. (Probably should've clarified that in my first post.)
BUT I think you're correct in that she's testing her boundaries with us right now. "What are the rules and how much can I get away with?" I think we have remind ourselves that at times it's okay to "lay down the law" (in a loving way of course).
