Marcia commented "But I suppose your neighbors are at work and just don't even think about the dog all day". Actually, I think the dog was obtained just for the children. Here is what I have observed...
The woman living there is a single parent. There are 3 elementary-aged children. I have noticed a guy (I presume an ex) seems to visit every other week and do some yard chores and takes the kids away for a weekend. The woman and ex seem to get along well enough, but his car is never in the driveway for more than a few hours.
The children seem quite happy. In the Summer, there is a trampoline and a small aboveground pool. I hear them yelling in play, they run all over the backyard and they love their new dog. That is all wonderful!
But I am guessing the Woman does not like the dog all that much and may be annoyed with its endless barking as much as I am. It seems to me that, as soon as the children leave for school, the dog is sent outside and only brought in at dark.
It's one of those "the kids wanted a dog" things... So it does what dogs do. It runs around a lot. It protects its people from threats. It accepts the schedule set by its people, etc.
I don't blame the dog in any way, but I sure have known quieter ones!
