Well my pooch, has her own sofa chair and we are fine with that, but it sounds like your new pooch was used to that as well, you could try and engourage pooch to sleep else where, if you dont want pooch in lounge, you could set boundries and maybe put a baby gate in kitchen and set up nice bed for pooch there. Keeping in mind that your rescue pooch is maybe a bit bewildered ,but you have to set the boundries . If you dont want pooch on sofa and said pooch wont refrain, then i would set a bed up for pooch, some where else, where pooch feels happy and comfortable
