Toby'shuman - Have you or anyone you've known been in that situation and felt that it worked? I'm genuinely curious to know because I really want this to work out. I just don't want to separate her so much from the family.
Yep, unfortunately been there, done that, got the teeshirt and whilst it was not a perfect solution it sure as hell beat someone getting bitten.
One of my cousins asked my mum to childmind her little boy whilst she went out to work. Mum was at home, thought the money would come in handy, wanted to help her out so child came each morning at 7.30am and stayed till Dad picked him up at 6pm.
Unfortunately one of my mums Show Dogs took a dislike to the boy, why we do not know, as far as we could tell he hadnt done anything to her, but dislike him she did. (she was well socialised by the way).
Anyhow the only way the 2 could be in the same house was for dog and child to be kept seperate. In this case the dog stayed in the kitchen area with access to the back garden whilst the little boy (he was 3) stayed in the front room which had access to the front garden (fenced off) so never the twain met, literally.
Was it easy, nope, not one bit, we had to be careful the dog didnt run through into the rest of the house, but it worked and no instances of dog bites happened on mums watch so to speak.
I truly wish you all the best in this endeavour, if however, the solution of keeping them apart truly feels wrong for you and yours I would contact the rescue you got her from. They may have someone waiting in the wings who is an experienced Dobe owner who will know how to help your girl overcome her demons.
