I actually just got her four days ago from a lady that was - and I quote "annoyed with her" and "wasn't what she was looking for". I couldn't wait any longer i had to get her.
So issues with potty training too, but the tail was the confusing part. I think you guys are right. she gets scared very easily and thinks I'm going to do something mean when I call her lol, the poor thing freezes, and flops to her side.

So just a confidence boost? I take it lots of praise?
