Hi,
Terms like selfishness, rudeness and arrogance are a little strong. Personally I saw none of those in his/her comment. Since when is wanting to enjoy peace and quiet in one's home a sign of selfishness? Its also not an issue of "getting his way" - people have a right to peace and quiet in their homes, and barking dogs constitute a public nuisance. That's why the analogy with a crying baby is so laughable - crying babies aren't considered a public nuisance. Barking dogs are. You are asking for the victim to show compassion to the perpetrator. Seems backwards to me.
Name calling rarely leads to any solution. The truth is constant noise, and especially if it is disturbing the peace of the neighborhood, can cause all kinds of stress, sleeplessness, anger, and ultimately can lead to things like heart attacks or other kinds of attacks (not in the natural). If a person has tried everything else, talking to the neighbor or leaving them a note, sonic silencers., fog horns, and contacting animal control and there seems no hope, try small claims court. Record the sound and/or make a log, write down all efforts (the hearing officer will want to know that you contacted the owner AND animal control and got no satisfaction), and ask for nuisance damages. The limit in small claims is $10,000, and though I am not suggesting asking for that, if you have any medical evidence to offer of a stress related condition, mention that too. I am not for getting something for nothing, but having a dog owner served with a small claims court hearing notice (which you can do by certified mail OR a marshal, will get their attention. It is unfortunate, but having had experience in court helping a man who could not sleep in his own bedroom because the neighbor dogs were allowed to frolic and bark all night in a room next to his, and having a friend who asked a neighbor to do something about her barking dogs that barked nonstop in the afternoons and having the "nice" neighbor reply -"I am home all day and would hear them if they barked," I am convinced that sometimes people have to take responsibility themselves to move to the next step.
