I suppose the trouble is, if/when we/you find her, not sure what can be done anyway other than alert RSPCA or SSPCA.
I looked as I bet others have, at links to her name and noticed a Facebook link of some one who had not paid for a picture or similar, I bet they are always on the move and are clever at covering thier tracks, she has loads of Facebook friends with Labradors though. If I were you my head would be buzzing with ways to get her and I actualy dreamt about her and the dogs last night, the power of the tinternet aye!!!!!
