Thanks everyone

So yesterday and last night we didnt hear a thing from our girl which is not surprising. Dh spoke to some other neighbours this morning who they said that she wasnt a problem other than one night when she was upset. That happened to be the same night that night we had a lot a rain, and thats pretty normal behaviour when we get a heap of rain over a period of a few days.
Also we found another possum in a tree in our yard last night. Dog hates possums, and normally she wins in the dog vs possum stakes.
Last thing we found out yesterday was the neighbours grandkids were pulling on the fence and teasing her.

I do think they overstepped the line by suggesting we put her down, or even rehoming her. And I think that is the part that has hurt most. Not to mention the fact that apparently she has been a problem barker for over a year now but yesterday was the first time they have came to us to tell us about the problem and how on earth can we fix it if we dont know its going on.
From what Ive read about the barking diaries councils ask the complainer to keep, it does sound like they are trying to prevent neighbourhood bullying and disputes by getting the complainers to look at verything that is going on in the neighbourhood and not just on the dog. Thats good though, cause it is quite easy to forget about the rest of the environment and forget about the reasons behind why something is happening.
