Agree with Tory if you continue with putting the lead on and going out with them making noise it tells them this behaviour is ok , turn away from them and if this doesnt stop them put the lead away and move out of the area ignor them till they are quiet and go back again when they are calm . It could take a while to get them to get the message so dont worry if you dont make it out of the front door for a day or 2 it wont hurt them and it will stop the neighbours from moaning . All they are doing is displaying pack mentality getting excited at the thought of going out , In wolves ( all dogs are descended from these animals and they do still have basic instincts such as hunting even the cute ones ) when they get ready for going on a hunt they vocalise with each other and this is nothing more than such behaviour but you must make sure that they understand its you that calls the shots and when they go out its on your terms , and that means quiet and calm , perservere and you,l be ok
