(a)
The board of supervisors of any county or the governing body of any city may adopt Sections 30801, 30802, 30803, 30804, 30805, 30952, 31105, 31106, 31107, 31108, 31152, 31153, 31251, 31252, and 31254. If those sections are adopted by the board of supervisors of any county or the governing body of any city, those sections shall apply within the territorial limits of the county or the city, as the case may be. Nothing in this division requires a county to enforce those provisions within the territorial limits of any city located within the county.
(b)
Whenever the term “board of supervisors,” “county,” “county clerk,” or “animal control officer” is used in this division, those terms shall also be deemed to include the governing body of a city, a city, the city clerk, or the animal control officer of a city, respectively.
