Whenever a case of rabies has occurred in a locality, or when the proper officials of a government unit are apprehensive of the spread of rabies, the Department shall act to prevent its spread among dogs and other animals. The Department may order:
         a. that all dogs or other animals in the locality be:
             1. kept confined within an enclosure, or
             2. kept muzzled and restrained by leash.
         b. that all owners or keepers of dogs or other
    
animals take prophylactic measures as it deems necessary to prevent the spread of rabies.
        c. other measures as may be necessary to control the
    
spread of rabies.
    The Department may determine the area of the locality in which, and the period of time during which, such orders shall be effective.
