Constantly barking dog: solutions?

[TigerDroveAgain]

We’re in a hamlet in a valley. This means that noise travels a long way!

Some (normally charming) neighbours have a young Border Collie. It’s under a year but is dog size not puppy size.

I have no idea where it is all day - they are WFH - but every evening it goes into their garden and barks, and barks and barks. It’s 10pm and has been barking since 7. It means the garden is unusable without earplugs - same for 8 or 9 other houses.

So, Doghouse veterans: any suggestions? Then I could helpfully pass them on, won’t go well but better than putting up with it. I think the dog owners are clueless and at first I thought they were trying to train it not to bark or something (controlled barking???) but it’s been weeks and no improvement.

It didn’t do it when it was smaller, or perhaps it’s voice wasn’t so loud.

That's absolutely tragic, poor dog. If they think allowing that to happen OK then they clearly are clueless.
They either need to bring the dog inside or remove/ block from view whatever is making him bark in your position I would probably steal the dog

Poor you! We have a terrier and he is prone to barking IF there is a squirrel or a particularly annoying pigeon in the garden. If he is out there and starts barking I take him in straight away. I have desensitized him to the neighbours and we have also planted lots of greenery so he can't see their kids running which would also set him off. So ask them perhaps what they think cause the dogs barking and tell them to sort it. Good luck

Some collies are very noise sensitive and will bark at anything, so birds, cars, horses, peoples voices. They mark due to hearing things or due to movement.

Basically a bored unstimulated collie is very likely to bark. A collie left for three hours unattended in a garden is a bored collie.
