Summary

Riverside County requires owners of unaltered dogs and cats to spay or neuter the animal, get a veterinarian-signed certificate of sterility, or (for dogs) buy an unaltered dog license, enforced countywide by Animal Services in unincorporated areas.

City-specific rules exist: Jurupa Valley, Menifee, Moreno Valley, Riverside, and Temecula have their own mandatory spay/neuter rules that differ from Riverside County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

No person may own, keep, or harbor an unaltered dog or cat in violation of this section. An owner or custodian of an unaltered dog must have the dog spayed or neutered, or provide a certificate of sterility, or obtain an unaltered dog license in accordance with this chapter. An owner or custodian of an unaltered cat must have the animal spayed or neutered or provide a certificate of sterility.

Full Breakdown

County Code § 6.08.120 bars owning or harboring an unaltered dog or cat without complying: spay/neuter, a vet certificate of sterility, or an unaltered dog license (cats have no license option, sterility or a certificate only). Any impounded unaltered animal must be altered before release unless exempted. Exemptions cover animals too old or infirm to safely alter (with vet documentation), registered breeders' animals, and females over 10 or males over 12 years old (who still need an unaltered license).

Violations & Fines

Citation/infraction/misdemeanor penalties for a Section 6.08.120 violation apply only when the owner is concurrently cited for another animal-control offense, such as running at large, no license, or a leash violation.

Frequently Asked Questions

Do I have to spay or neuter my pet in unincorporated Riverside County?
Yes. Under County Code § 6.08.120 you must alter the dog or cat, provide a vet certificate of sterility, or (dogs only) buy an unaltered dog license.
Can I be fined just for owning an unaltered pet?
Only if you're also cited for a separate offense, like running at large or no license: the spay/neuter penalty attaches to that citation under § 6.08.120(E).
