Chicago does not mandate spay or neuter for owned pets. Instead, MCC 7-12-140 charges intact dogs $50 versus $5 for sterilized animals, and Chicago Animal Care and Control runs low-cost and free clinics through partner organizations to encourage compliance.
Unlike Los Angeles, Chicago has not adopted a mandatory sterilization ordinance. MCC 7-12-140 and 7-12-170 build a price incentive: $5 annual licenses for spayed or neutered dogs and cats, $50 for intact animals, with senior discounts. CACC partners with PAWS Chicago, Anti-Cruelty Society, and the Chicago Animal Welfare League to deliver free or reduced-fee surgeries for income-qualified residents. Adopted animals from CACC under MCC 7-12-310 must be sterilized before release at the shelter's expense, and mandatory sterilization applies to dogs declared dangerous under MCC 7-12-051. Breeders of three or more litters per year face commercial pet-dealer licensing under MCC 4-384.
There is no general fine for keeping an intact pet. Dangerous-dog owners who fail to sterilize under MCC 7-12-051 face fines from $300 to $10,000 and possible animal forfeiture. Adopters who skip required CACC sterilization breach their adoption contract.
