Don't know if you ever saw the dog training thing on Ch 4 with the long haired woman, she was pretty good. When a dog kept jumping up at her she would turn her back and fold her arms. They do it for attention. You mustn't make eye contact either. You keep opening the door and doing the same thing, time after time, with guests as well. When dog is good and does it right, praise him and treat him. Try it. You should never let your dog go through the door before you or anyone else either otherwise it send signals to them that they are in charge, YOU are the leader of the pack so you have to show them. Its hard work at first, but persevere. Better than tying them to the post but it is what ever works for you. Firm short sharp "DOWN", use a rattle bottle as well (plastic bottle full of small stones) and when you say DOWN shake the bottle. Makes a hell of a row but scares the dog and they instantly go down. Good Luck.
