Sorry daisy love I think you're flogging a dead horse here. If there is a dog with issues it needs firm, kind stability and an owner who will ensure that it is not further stressed by rehoming it AGAIN because she hasn't got her affairs in order. If she couldn't afford it then she oughtn't to have had the poor dog in the first place, certainly not if she was going to resort to a collar to get it to stop barking, as that just smacks of someone who doesn't know what the hell they are doing and that is the last thing a dog whose already distressed needs. People are bound to draw conclusions about things from the way you've posted as evberything sounds so erratic, unplanned and unknowledgeable.
