SACRAMENTO -- The state Assembly approved a bill Monday that allows cities and counties to regulate certain breeds of dogs, a reaction to a wave of pit bull attacks in the San Francisco Bay area. Current state law prohibits municipalities from passing any ordinance that targets a specific breed of dog. SB862, by Sen. Jackie Speier, D-Hillsborough, allows local governments to require spaying and neutering of specific breeds and to shut down so-called "backyard breeders" that are linked to the breeding of attack dogs. It passed on a 46-18 vote.
