Sounds like the dog is trying to find out who is the boss (pack leader) do not show your fear. when he barks, you need to stand up, shoulders back head up ,don't look in his eyes look over his head, make shore he has a lead on in the house an till he is trained,, take him by the lead and take him to his bed, or the other side of the room, , don't talk to him till he is where you want him to be. make him sit or down, then say in a deep voice, stay . Walk away, if he fallows you, again take his lead and lead him back, , you need to do this an till he stays. And it may take some time, so put some time aside for this training. You can say no, if he starts to move, but try not to talk to him to much, don't forget to stand tall . He needs to see you are boss by the way you stand. Once you have got him to stay for 5 mins, go over and tell him good boy. And play with him a bit. Hope this helps
