I did wonder about that DA. And still do think that maybe it was a combination of both.
But she did spend a lot of her time hiding under the table, or under a chair, or behind a stool and even behind my legs. So its not like she was in front of me barking. She has barked at Batty once before and AGB said that it was her thinking she needed to "protect" me. But we have been VERY firm with her since then doing the TOT and NILIF and really showing her that we are boss not her!
AGB said she noticed a big difference in her and her behaviour this weekend which was good to hear as it means we must be doing something right!
The other thing she did that made me thing fear was that if I walked away she would REALLY hesitate before coming to where I was if she had to go past one of the visitors.
