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

California sets the outer limits here. Food and Agricultural Code section 31683 lets cities and counties adopt their own dangerous-dog and vicious-dog programs, but expressly bars any program that is 'specific as to breed' from being used to declare a dog potentially dangerous or vicious; the only breed-specific local rules allowed relate to mandatory spaying, neutering, or breeding of a specific breed. As a result, Lake County does not - and legally cannot - ban or automatically classify pit bulls or any other breed as dangerous just because of breed. Instead, the County and the state regulate dogs by behavior: under Food & Agricultural Code sections 31601-31683 a dog can be declared 'potentially dangerous' (for example, after two unprovoked threatening incidents in 36 months, or biting a person, or twice seriously injuring another domestic animal off the owner's property) or 'vicious' (for example, after an unprovoked attack causing severe injury). The County's own animal provisions sit in Chapter 4 of the Lake County Code and are enforced by Animal Care & Control. Note one breed-adjacent point that does apply locally: Lake County's mandatory spay/neuter ordinance (Lake County Code section 4-17) requires dogs and cats over four months to be altered, with exemptions for registered breed-registry animals and certain working dogs - this applies regardless of breed. There is no separate breed registry, breed insurance mandate, or breed muzzle rule published for the unincorporated county.
