We try to give the advice start as you mean to go on with a rescue, sort of give a clean slate, but sometimes the effects of being kenneld can influence this, if the dog has been in kennels(possibly with other dogs) usually they are left alone at night when the staff go home, the dogs can and do use the toilet in the kennels, they may bark during the night which the rescue cannot verify, the dogs may have a little seperation anxiety, its possible that your little one is trying to adapt to another new home, (its first-then rescue_then you) so its not sure of the rules yet, if you stick to your guns usually the pup learns what is accepted and what is not, it learns that once you go upstairs you are not lost for good you will appear in the morning, once it learns this then things will hopefully settle down, its so much the dog has to take on board, and if you are consistant it should get over these issues quicker than, one minute not allowing something, then changing your mind and then allowing it if you see what I mean, but you may be in for a few sleepless nights til the dog learns its new routine.
