We have a Jack Russell X that barks at anything he thinks is in our garden, like the window cleaners long brushes over the back, or seeing next door through the fence.
I know how annnoying barking dogs are so we only put him outside for as long as it takes to do his business, then bring him in. We can't leave the back door or window open because he barks which is a pain but that's our problem and I don't think it's fair to infict him on anyone else.
A woman has moved in 2 doors down with a black lab. Every morning she puts him in the garden at about 7am and leaves him out there until (I assume) they go to work/ school. He has a really loud deep bark and he lets off a volley of barks every morning at 7 I am woken up by it now every day.
The second our dog sets foot outside our back door the lab starts to bark. Sets ours off. If I go to put washing out the lab barks. It can't even see into our garden! When it barks they don't bring it indoors, and their back door is open whenever they are in.
To add to this, we also have new neighbours next door on the other side and they have a big dog too. If it goes in the garden when the lab is out the lab barks, it barks back and every dog on the estate starts up. (don't have any problem with their dog as it doesn't bark unless the lab starts it)
I haven't said anything to the lab's owners because they haven't been in long and I thought the dog would settle down. It hasn't. Everyone else brings their dog indoors if it barks- the fact that they don't suggests talking to them is going to be awkward. Any opening line I can think of sounds confrontational.
Do we just grit our teeth and put up with it? WWYD? (it's out in the garden barking again as I type..) We can't hear dogs through the walls so it's only if they are outside, or if it's barking indoors and you are outside that it's a problem.
