Well, luckily for me my dog doesn't really have that problem...except for when we're outside and she gets a bit excited. Friends of mine gave me ideas when she was a little puppy though for when that time was to come. I'd been told that when they jump, you should stick your knee out (not kicking them) but blocking, then their chest will hit your knee and they should start thinking that everytime they jump up that they're going to bang into something not quite pleaseant. eventually they should stop. you could also try getting your dog to sit and stay by the door when people are entering and have your guests come up to the dog. everytime your dog doesn't run over and jump praise him and give a treat. i don't know if this will help but it was adivse given to me. melissa
