I just spoke with DH. He said you really don't need to worry. You would need complaints from more then one neighbour for anything to even get close to happening. He said they don't tell people how to stop their dogs from barking as situations are always different and dogs are too, they just tell you to try and do something about it.

Your still doing the right thing by looking into before council is even involved and if none of your other neighbours see an issue there is no problem.

When I told him your neighbours sugestion of putting the dog down or rehome he just laughed. Said that will never happen
