We "fostered" a relatives dog last June while she got through a difficult patch (house move, new jobs, new baby). Initially it was going to be for a couple of months, but it has stretched, and she is still with us, although she is still their dog. They now want her back for the summer holidays, and have asked if we will have her again in October. Obviously she is their dog, so we have to say yes- but please tell me she will be all right. Will she have forgotten them? And if she hasn't will she be really upset at leaving them again in October? And if she has, will she be upset about leaving us? And is it mean to let her settle in with them disrupt her again by giving her back to us? Am I inventing problems that don't exist because I don't want to give her back?
