Chino, CA
San Bernardino County
California Food & Agricultural Code §31683 preempts breed-specific dangerous-dog ordinances — no city, including Chino, may declare a breed dangerous or vicious by breed alone. The only carve-out is Health & Safety Code §122331, which lets local governments require mandatory spay/neuter and breeding regulation by breed. Through its San Bernardino County animal-control contract, that exception applies in Chino: San Bernardino County Code §32.1501 requires pit bulls and pit-bull-mix dogs over 4 months to be spayed or neutered.

Chino FAQ
Can Chino ban pit bulls?
No. California Food & Agricultural Code §31683 preempts breed-specific bans, and Health & Safety Code §122331 expressly forbids declaring a breed or mixed breed potentially dangerous or vicious. The only allowed breed-specific local rule is mandatory spay/neuter.
Do I have to spay or neuter my pit bull in Chino?
Yes. Chino's animal-services contract with San Bernardino County brings County Code §32.1501 into play, which requires all pit bulls and pit-bull-mix dogs over four months old to be spayed or neutered, subject to narrow medical and registered-breeder exemptions.
How are dangerous dogs handled in Chino?
On an individual basis under California Food & Agricultural Code §31601 et seq. A dog can be declared 'potentially dangerous' or 'vicious' based on its own behavior — never solely on its breed.
Ontario FAQ
Does Ontario ban pit bulls?
No. California state law preempts breed-specific bans. Ontario uses a behavior-based dangerous dog process under state law.
Can my HOA restrict breeds?
Yes. Private HOAs, landlords, and insurance carriers are generally not covered by the state preemption and can maintain their own breed lists.
