Tuesday: sounds like he needs to be decenitized (sp) put him on his leash and make him site about 6 feet away from the door...have someone walk through it...if he starts acting up,you IMIDIATLY say NO! or AHH-AHH and walk him away from the situation.Down the hall,whatever s he can't see what is going on anymore.Walk him back a few feet at a time and make him sit after each time you stop.This will help get him out of this frame of mind..You will have to keep doingthis with your dog...don't overwhelm him though.Only do it about 5 or so times at first,while teaching him.EVERYTIME though when someone just comes to the door,say to visit you.REPITITION is the key.
