Livermore Breed Restrictions Rules (2026): What You Need to Know

The City of Livermore's municipal code contains no provisions targeting specific dog breeds for prohibition or heightened regulation. This is consistent with California state law: Food and Agricultural Code Section 31683 explicitly prohibits any city or county from enacting or enforcing an ordinance that declares a specific dog breed — or dogs of any specific breed — to be dangerous or vicious. The preemption prevents Livermore from instituting a pit bull ban, a Rottweiler restriction, or any similar breed-specific measure that singles out dogs based solely on breed characteristics rather than individual behavior.

One narrow exception exists under California Health and Safety Code Section 122331, which allows localities to adopt breed-specific mandatory spay/neuter ordinances, but the City of Livermore has not enacted any such provision and all breeds are treated identically under current city law.

Animal control services within Livermore are provided by the Livermore Police Department Animal Services Unit. The behavioral framework follows California Food and Agricultural Code Sections 31601 through 31683. A dog may be declared potentially dangerous if, on two or more separate occasions within a 36-month period, it has bitten, attacked, or caused physical injury to a person or domestic animal without provocation while off the owner's property, or if it has approached a person in a menacing manner while unprovoked and not confined. A dog may be declared vicious if it has killed or caused severe injury to a person without provocation, or if it was previously declared potentially dangerous and the owner failed to comply with all conditions imposed. These determinations follow a formal investigation and, upon the owner's request, an administrative hearing. The evaluation applies uniformly to all dogs regardless of breed, size, or appearance.

Livermore is an eastern Tri-Valley city of approximately 90,000 residents with a suburban and semi-rural character, including neighborhoods adjacent to vineyards, ranches, and open rangeland along the Altamont corridor. Dog ownership is common across all neighborhoods, and the city's behavior-based approach ensures that responsible owners of any breed are treated equally. Many Livermore properties feature larger lots where dogs may interact with livestock, horses, or wildlife, reinforcing the importance of behavior-based rather than breed-based regulation.

Owners of dogs declared potentially dangerous or vicious must house the animal in an escape-proof locked enclosure when not under the direct physical control of a responsible adult, post conspicuous warning signs at all property entry points, have the animal spayed or neutered within a specified period, and maintain a minimum of $100,000 in liability insurance covering bodily injury and property damage.
