How to Find Out If the Dog Has Bitten Before
After a bite, one question comes up almost immediately: has this dog done this before? The answer matters more than most people realize — and it's on record more often than most people expect.
Why the history matters
For your safety and your neighborhood's. A dog with prior bites on record can be subject to a "potentially dangerous" or "vicious" dog proceeding under California law (Food & Agricultural Code §§ 31601–31683), which can require secure enclosures, muzzling, insurance, or more. Those proceedings usually only start when incidents are reported and documented.
For your claim. California owners are strictly liable for bites in most situations even if the dog has never bitten anyone (Civil Code § 3342) — so you don't need a prior bite to have a case. But a documented history changes the picture: it can support negligence claims, punitive exposure in egregious cases, claims against a landlord who knew about a dangerous dog, and it materially affects how an insurance company values the claim.
Where a dog's history lives
There's no statewide public database of dog bites. The history lives in the files of the local agency that handles animal control where the dog lives — which is why identifying the right agency is step one. Records that may exist:
- Prior bite reports naming the same dog or the same owner.
- Prior complaints — "dog at large," aggressive behavior, barking/menacing calls to the same address.
- Quarantine records from earlier bites.
- Dangerous-dog designations or hearings, if any incident was serious enough.
- License and vaccination records, which help match "the dog at that address" across incidents.
Neighboring records matter too: county public health departments keep bite reports filed by doctors, which sometimes capture incidents animal control never heard about.
How to ask
These are agency records, requestable under California's Public Records Act. Two practical tips:
- Ask by address and description, not just by name. "All bite reports, complaints, and investigations involving dogs at [address]" catches incidents where the owner's name was recorded differently — or not at all.
- Ask for the dog specifically. Breed, color, size, name if you know it, license number if the agency will confirm one.
Agencies may redact some personal information, and practices vary — some agencies are quick and open, others require follow-up. Persistence matters.
What if neighbors know things?
Neighbors are often the best source of unwritten history — "that dog has gone after three people on this street" is something you'll never find in a database. Write down what you're told, who said it, and when. If the history is real, encourage those neighbors to report their own incidents, even late; every report builds the official record that protects the next person.
The honest caveat
Sometimes the answer is: the dog has no history on file. That does not weaken California's strict liability rule — the owner is still responsible for your bite in most circumstances. The history search is upside: if it's there, it helps; if it isn't, you've lost nothing.
