Hello Kelly-Louise, As someone who went through a similar scenario...where we got to the point of making arrangements to sell our house - because life was almost untenable at home (the neighbours from hell) - all of a sudden and right out of the blue, these neighbours moved out - two weeks ago today. True, they were only renting, but I guess the message is that sometimes matters do resolve themselves. It is just so wonderful not going to bed with earplugs in....
So my message, take whatever actions you need to for your poor little pooch's sake, but know that things often sort themselves out.
That's my wish for you and Sasha....
