Colusa County, CA Animal Ordinances: Breed Restrictions (2026)

Colusa County Code Chapter 3 (Animals and Fowl) regulates dogs through leashing (Section 3-7), at-large injury (Section 3-8), licensing, and rabies control, but contains no breed-specific legislation and no separate "vicious" or "dangerous dog" classification keyed to breed. The Zoning Code, Chapter 44, likewise contains no breed restriction. The county's only behavior-based dog rule is Section 3-8, under which an owner of a dog running at large that directly or indirectly causes injury (a wound requiring medical treatment such as lacerations needing sutures, puncture wounds, or broken bones) is guilty of a misdemeanor or infraction, regardless of the dog's breed. At the state level, California Food and Agricultural Code Section 31683 provides that no program regulating any dog may be specific as to breed, with a narrow exception (under Health and Safety Code Section 122331) permitting breed-specific spay, neuter, and breeding requirements. As a result, a Colusa County resident is not barred from owning any particular breed, and any future county regulation declaring a dog potentially dangerous or vicious must apply equally to all breeds.
