Amends GS 67-4.1 to require any person or animal control board making a determination that a dog is a potentially dangerous dog under the statute to impound the dog in addition to notifying the owner as previously specified. Now provides that if a potentially dangerous dog determination is upheld or the owner of the dog does not appeal the determination, the dog can be returned to the owner only upon the owner paying the costs of impoundment and the person or board that made the determination finding that the owner's confinement of the animal meets the requirements of GS 67-4.2(a)(1) (which allows the owner to leave a dangerous dog unattended on the owner's real property if the dog is confined indoors, in a securely enclosed and locked pen, or in another structure designed to restrain the dog).

Amends GS 67-4.3, making the owner of a dangerous dog that attacks and kills a dog under immediate control of a person guilty of a Class 1 misdemeanor. Defines under the immediate control of a person to mean on a leash or held in the arms of the person.
