We had a new couple move into the house behind ours. They themselves are fine, but they leave their dog in their garden ALL DAY and it barks non stop... literally ALL DAY! It's a really high pitched yapping bark too which makes it all the more frustrating.
We're going to leave it for a few more days but if it carries on we're going to have to do something about it because it's so loud, it's the most annoying thing ever. Not sure what we're going to do though
