I fell out with my neighbour a few times last year due to her barking dog being left alone all day. All complaints were just the odd watsapp conversation and I once put a little note through her door (because I'd lost all my phone numbers) telling her that her dog was in distress and it was driving me mad. I never actually reported it to the council or anything, it was just a clash between the two of us almost a year ago. We've kind of made up since, the noise issue hasn't been as bad but only because her lodger has been there, it's still a fucking nightmare when alone and always will be. If I was to eventually sell up (I never intended to stay here forever) do I legally have to declare this?
