Some municipalities and counties in California have breed-specific laws, or breed-specific legislation (BSL), regarding some canines. Examples of these breeds of dogs include: the Pit Bull, the American Pit Bull Terrier, the Staffordshire Bull Terrier, Dobermans, Rottweilers, and German Shepherds. These ordinances pertain to spay or neuter programs and breeding restrictions and requirements. A goal of spaying or neutering surgeries is to prevent aggressive behavior towards other animals.
