Hi, I took a look at your other thread,

Mines the same with guests, we have been working on crate trainning since day one with him, and he quite happily settles down there (after we manage to get him to stop barking) - we never close the door on him though - he's free to walk in and out.

I think it is important to speak to guests and explain that they just need to egnore the god until he stops barking/ jumping. That really seems to work with archie, and when hes calmer we get the guest to give him a treat, he realises then that they are not a theat and they are welcome. But we only do that when hes calm.

I would speak to your neigbour and explain that you are trying to do something about the barking and it really isn't helping what he is currently doing, I'm sure it just gets them more upset. We are currently using the pet corrector spray (you can get it from pet shops - its just air in a spray can that makes a noise) and say quiet in a stern voice, once he stops barking I then say good quiet in a much brighter happier voice, its working in the house and garden as ours hates anyone walking past - this is a real problem for us as we live next to a church and school!

Don't know if any of that can help you, and good luck!
