Los Angeles FAQ
Are there exemptions to the spay/neuter law?
Yes. Registered breeders, show or working dogs, guide and service animals, and animals with a veterinarian's medical exemption can stay intact, but each requires an intact-animal permit and annual renewal.
What if I just got my puppy or kitten?
You have until the animal turns four months old. After that, schedule sterilization or apply for an intact-animal permit. Low-cost spay/neuter vouchers are available through LA Animal Services.
San Francisco FAQ
Does this apply to mixed-breed pit bulls?
Yes. SF Health Code 43 covers any dog with substantial pit bull-type characteristics as identified by Animal Care and Control officers, including mixes. Visual breed identification is permitted under the ordinance.
Are exemptions available?
Licensed breeders, dogs medically unfit for surgery with veterinary certification, and competition dogs may obtain intact-dog permits. Owners must apply through SF Animal Care and Control before keeping an intact pit bull.
