Los Angeles, CA
Los Angeles County

San Diego County
San Diego does not impose blanket mandatory spay/neuter, but SDMC §44.04 charges sharply higher license fees for unaltered dogs and requires breeding permits. The 2008 ordinance pushed sterilization through fee structure rather than outright mandate after political pushback.

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 Diego FAQ
Is spay/neuter mandatory in San Diego?
Not strictly. The city uses a steep license-fee differential and a breeder-permit requirement under SDMC §44.04 to encourage sterilization rather than imposing a flat mandate like Los Angeles.
Where can I get low-cost spay/neuter?
San Diego Humane Society and partner clinics offer income-qualified low-cost spay and neuter, and county vouchers reduce surgery cost for residents under listed income thresholds.
