It is unlawful for the owner or custodian of any dog or other animal to permit, either willfully or by failure to exercise due care, such animal to commit a public nuisance by defecating upon private property without the permission of the owner or custodian thereof, upon the public sidewalk, in or upon any public street or in or upon any public place where persons customarily walk. It shall be a defense to a charge under this section that such owner or custodian of the dog or other animal immediately removed and properly disposed of the feces deposited by the dog or other animal. (Ord. M-2656 §5, 1986: Ord. M-2397 §15, 1983)
