Our neighbor has a dog that barks every time it it's left on its own, we always text him to tell him, it drives us absolutely insane. My particular favorites are when he goes out at 8 in the evening and doesn't come home till 4 in the morning. I feel your pain, it is soul destroying.
Yes drop her a message but no need to ‘shame’ her. There’s a chance she doesn’t have a clue how bad the barking is when the dogs left alone. Poor thing sounds like it has really bad separation anxiety.
Just message and say you’re not sure if they’re aware that the dog barks constantly and sounds in distress currently. Say not the first time it’s happened so wanted to say something in case they weren’t aware as you’d hate to think of the dog being stressed. Give them a chance to do something about it in a nice way and if they don’t then you can get more firm. My mums dog barked a couple of times when she left him and she had no clue, the neighbours messaged her concerned (& obviously disturbed by the noise), my mum was super apologetic and dealt with the issues or made alternative arrangements when going out. Nice to give them a chance to work on it even though super stressful for You at this sec but think it’s good to start out nicely and try to keep neighbourly relations.
I’d tell her. My parent’s neighbours told them their dog barked all day. They had no idea. They’ve now started shutting him in a smaller room which makes him feel more secure and things are much better. Just don’t do it on fb- pop round for a chat so you can sound concerned instead of annoyed. Hard to read tone in messages
I’d rather someone told me, although I understand that it’s difficult to gage how a neighbour will behave. I have two dogs who don’t bark much when we are home (they are outside during the day, so don’t get interaction all the time, but often) and I was unaware until a neighbour told me they bark all night when I’m working (permanent nights) was highly embarrassed and ensured the dogs stayed in overnight when I’m not home from that point on. I’d rather be able to deal with something and hated the fact that the dogs and the neighbours had been so unhappy!
