I simply left a note asking my neighbor to come talk to me about the barking dog and got yelled at when he came home. I called animal control which is handled by the sheriffs at that location. Seems the officer responsible for that duty is an animal lover and told me, "of course the animal barks". I gave up.
I was being woken up every morning by the dog barking when the owner left and put the dog in the back yard for the day. I don't know if the animal barked just at the time he was put out or if something disturbed him. But it lasted long enough to wake me up and that is not an easy thing to do before my 8 hours are up. So the dog was barking for some
10 minutes at least. I don't get why this didn't bother everyone in the townhouse cluster.
