Whenever rabies becomes prevalent in the City, the Mayor shall,
according to the necessity of the case, issue a quarantine order,
requiring every owner or person in charge of any dog or dogs within
the limits of the City, to either kill or impound his/her dog or dogs
or to have such dog or dogs immunized. Said order shall be published
once in the paper officially publishing the business of the City and,
in the absence of such paper, shall be posted as in case of sales
of personal property. The Mayor is authorized by proclamation to terminate
any such quarantine whenever, in his/her judgment, the necessity for
it no longer exists.
