Graciesmom, yep, her previous home was as a breeder in a puppy mill - so she is timid on the floor and relaxed/content on the couch near me. This is why i think she us "safe" there - but no, the floor is of no danger to her...no other pets or kids here
I do agree walks would be VERY good for her - we live on a quiet corner so i have been trying to get her to go from the back yard, along the side yard, and then along then front - and up the front door. We r making progress on that.
Thank you all for your responses - what i am hearing is reassuring that with patients and routine she will come around, and that she is indeed capable

i just have to take a minute to share a HUGE milestone, Maggie May played with a toy today! She chewed and played with a small plush. I have been leaving a few around and suddenly today she must have been comfortable and trusting enough to let her walls down a bit!
