When our next door neighbours go out, they leave their dog at home. When their dog is home alone, it barks continuously. Today it has been barking since midday. It's just stopped because they have got home, but often it barks all day. You can hear it all over our house.
This is really more of a WWYD than an AIBU. Should I tell them their dog is barking (and risk them saying, well, we hear you shouting at your children). Next door neighbour is a grumpy old sod, and I am nervous of a face-to-face confrontation, but don't want to leave a note. Is it cruel to leave a dog to bark for so many hours? Is it possible they just don't know this is going on, since the dog stops when they get home?
