I know from both sides and feel that dogs should not be let to bark. Unfortunately some people do take things to an extreme I have learned. I do not allow my dogs more than a few times. We do not have a barking ordinance where I currently live, and you can tell. I feel it is rude, but most of the time, it is pretty quiet. OTOH, where I lived before, there was a barking ordinance. The neighbor did not like my dogs because of their breed. She would call the animal control daily and make false complaints of excessive barking. When they would drive by, they would be on the back porch resting or under the tree. I feel it is rude. She never once came to me with a complaint and I finally went to her. Feel lucky that your neighbor is coming to you with the complaint. She ended up being warned by animal control to stop making false calls. They loved my dogs. I was more than happy when I moved.
