She is a beautiful little thing. I am glad that she is getting to be more comfortable with you. Hopefully things will keep improving now that she is feeling safe and secure.

My friend Km taught her Newf, Ella, to ring a beel on the door when she needed to go out. It worked really well! But sometimes Ella would ring it and then NOT go out. She would ring it because that would get Kim to stand up and walk over to the door and open it and pay some attention to Ella even though it was usually just to express her annoyance at being made to get up for nothing! So it may not be a perfect solution but it will certainly help. :)
