A. It is unlawful for any person owning, harboring or having the custody, control or possession of any dog to cause or permit such dog to:
1. Be in or upon any street, alley or other public place, or in or upon any unenclosed premises unless such dog is continuously controlled by a competent person;
2. Commit any damage or nuisance upon the property of any other person or upon a public street, alley or other public place.
B. When dogs are found running at large and their ownership can be ascertained by the dog officer, such dogs need not be impounded, but the dog officer in his discretion can take the dogs to their owners and may cite such offending owners for violation of the provisions of this chapter.
