"people from mississippi do follow this site."
OK...no one (including no lawyers) from MS posts here with any regularity.
"He can bark as he wishes. I can not be "slapped" with a fine as you say simply because he is barking."
If you're going to be argmentative, I suggest you at least pay attention to what I say. I didn't say you could be slapped with a fine. I said you could be slapped with a nuisance lawsuit. And the opinion of some non-lawyer with animal control will have no relevance if that happens. Yes, you're entitled to have your dog in your yard, but your right to do so is NOT superior to your neighbor's right not to endure a barking dog for nine hours a day every day.
But you're free to believe what you want and not do anything about the situation. Just don't be surprised if your neighbor introduces your dog to his friend, Mr. Hershey Bar.
