Dangerous or vicious dog designations in Concord are determined under California Food & Agricultural Code §31601 et seq. by Contra Costa County Animal Services following a behavior-based hearing. California Food & Agricultural Code §31683 preempts breed-specific legislation, so designations rely exclusively on documented aggressive behavior.
Dangerous dog enforcement in Concord is handled by Contra Costa County Animal Services under California's statewide Potentially Dangerous and Vicious Dog law (Food & Agricultural Code §§31601–31683). A dog may be designated Potentially Dangerous following two aggressive incidents (unprovoked off-property behavior causing a person to defend themselves, or attacks on other domestic animals) or Vicious after a severe injury attack. Designations are made through an administrative hearing where owners can contest evidence. Consequences of a Potentially Dangerous designation include mandatory registration, secure enclosure, muzzle and leash in public, posted warning signs, and annual registration renewal. Vicious dog designations may require permanent confinement or euthanasia. Critically, Food & Ag Code §31683 preempts all local breed-specific bans, meaning Concord cannot and does not ban pit bulls, Rottweilers, or any other breed; designations must be based on individual dog behavior only. Owners of designated dogs face elevated liability and may be required to carry additional insurance.
