Our neighbors have a little yap yap dog, the fence is right near our bedroom window so we can't get to sleep most nights and get woken before 6am every morning... He barks whenever he hears us walk IN OUR HOUSE, will bark whenever he sees our dogs in our yard and is especially annoying when I'm putting washing on the line. His owners do not care, there has been so many times where they've been in their yard with him, I've been in my yard and he's been barking his head off and they don't say a thing. A few weeks ago I had the cat outside with me and he was going ballistic, the owner said "be quiet! That's rude!" And I just said "the cat is with me so that's probably why".. They didn't say anything back and didnt try and shut him up after that... I never said the barking was okay, I just explained why he was. If we yell at him to be quiet, he barks more. It's awful. It's a 6ft wooden fence but he can see through the gaps.
I must admit, I'm guilty of giving him a few sprays with the hose
