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

No breed-specific legislation was found in Mariposa County's Animal Control code. The county's Vicious Dog provisions in Section 6.08.300 define a dog as vicious or dangerous based on conduct, such as an unprovoked attack causing injury, property damage, or an attack on another animal off the owner's property, rather than by breed. In September 2025 the Board of Supervisors voted to expand these rules, including a new vicious-dog chapter, but the published description continues to define vicious and dangerous dogs by behavior, not breed. A dog found vicious or dangerous by a court must be registered with the Sheriff's Office within ten days (registration fee up to $25) and is then subject to strict confinement, permanent identification (tattoo or microchip), posted warning signage, secure muzzling and heavy restraint when outside the enclosure, and proof of liability insurance before release. California state law reinforces the absence of breed bans: Food & Agricultural Code Section 31683 allows local dangerous-dog programs but prohibits any program that is specific to a particular breed. Owners of any breed should focus on the county's leash, at-large and vicious-dog rules, which apply uniformly regardless of breed.
