Summary
Napa County does not ban any dog breed. California Food & Agricultural Code 31683 prohibits cities and counties from enacting breed-specific dog programs except for spay/neuter and breeding rules. HSC 122331 likewise forbids declaring any breed potentially dangerous or vicious. Napa County uses its conduct-based Dangerous Animals ordinance (Chapter 6.16) instead.
Notwithstanding any other provision of this chapter, cities and counties may enact dog control ordinances that are not specific as to breed. This section does not affect any rights of an owner of a dog under any other provision of law. Nothing in this section shall be construed to prohibit a city or county from adopting or enforcing its own program for the control of potentially dangerous or vicious dogs that may incorporate all, part, or none of this chapter, or may punish a violation of this chapter as a misdemeanor or may impose a more restrictive program to control potentially dangerous or vicious dogs, except that no program regulating any dog shall be specific as to breed.
Full Breakdown
Under California Food & Agricultural Code section 31683 'no program regulating any dog shall be specific as to breed,' with a narrow exception only for mandatory spay/neuter or breeding programs adopted under Health & Safety Code 122331. HSC 122331(a) further provides that under any such program 'no specific dog breed, or mixed dog breed, shall be declared potentially dangerous or vicious' and limits the permissible measures to spay/neuter or breeding requirements. Napa County has not adopted a breed-specific mandatory spay/neuter ordinance. 16 (Dangerous Animals, originally adopted as Ordinance 1296 in 2007), which defines a 'potentially dangerous animal' as 'any animal which, when unprovoked, engages in aggressive conduct prompting or resulting in defensive action by any person to avoid bodily injury' and lays out hearing, registration, confinement, sign-posting, microchipping, spay/neuter, and liability-insurance requirements for any dog that meets the conduct criteria, regardless of breed. Owners of dogs that injure people remain strictly liable for bite damages under California Civil Code section 3342, again without reference to breed.
Violations & Fines
Because no breed is restricted, there are no per-breed penalties. Owners of any dog (regardless of breed) determined under Chapter 6.16 to be potentially dangerous or vicious face mandatory registration, secure-confinement orders, warning signs, microchipping, spay/neuter, special-purpose insurance, and potential misdemeanor sanctions and civil penalties under section 6.16.100 and section 6.16.110. Bite victims may sue under Civil Code 3342 for strict liability damages.
