When the State Health Commissioner has declared that an outbreak of rabies exists in a county or city, he may adopt a regulation requiring all dogs therein to be vaccinated or inoculated against rabies, with such exceptions as he deems appropriate. Such regulation shall set forth the persons by whom and the time within which such vaccination or inoculation may be required. The State Health Commissioner may establish such clinics and furnish other services and supplies as will enable the prompt vaccination or inoculation of all dogs in such county or city.
