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

There is no breed ban in the Mono County Code. Mono County's dog rules in Title 9 (Chapters 9.36 and 9.44) regulate behavior - dogs at large, barking, attacking pedestrians or vehicles, and nuisance - not breed. This is consistent with California Food and Agricultural Code Section 31683, which states that 'no program for the control of potentially dangerous or vicious dogs shall be specific as to breed.' Under that statute, any 'potentially dangerous' or 'vicious' dog determination must be based on the individual animal's conduct, such as biting without provocation or aggressively chasing a person, under the procedures in Food and Agricultural Code Sections 31601 through 31621. California does allow a narrow exception: local governments may adopt breed-specific spay/neuter or breeding requirements (Section 31683), but Mono County has not been shown to have adopted such a program. As a result, ownership of any breed is permitted in unincorporated Mono County so long as the owner complies with licensing, rabies vaccination and the behavior-based nuisance and leash rules. Insurance carriers and individual landlords may impose their own breed conditions, but those are private restrictions, not county law.
