Are there rules about dogs as far as noise of barking or roaming the area without a leash?
There are several rules governing animals and acceptable behavior (including constant barking), etc. The attached Exhibit B addresses these items specifically. Common sense should prevail here as well. If you notice your dog barking a lot, it is likely that your neighbors notice it too, and common courtesy would indicate that you take care of whatever is causing the barking so that it is not a nuisance. The “golden rule” is always a good perspective.
