<human>: Give me the gist of the text in a nutshell

We just got a letter from animal control in our area. An anonymous neighbor has called them about our dog "barking excessively" which is somehow illegal where we live. I don't need advice on how much bulls*** that is, just suggestions on how we might get him to quiet down if it becomes necessary.

Some more info, we live in a rural area. Probably about five houses within range to hear the dog. I am willing to bet it is this b**** of a neighbor that we have (she confronted us that our cat was coming on her, unfenced, property and expected us to keep him indoors). Also, there is a fire station within a mile whose siren is almost deafening, so I doubt it is a matter of ruining the calm. Just someone who isn't happy unless others aren't.
<bot>: need tips on how to train a dog not to bark at things like squirrels or deer or sirens or our outdoor cat or car doors or really anything that happens outside during the daytime.
