Florida Dog Bite Law: Strict Liability, a Negligence Offset, and a "Bad Dog" Sign

A sign reading Bad Dog is a real statutory defence in Florida, and it is narrower than most owners assume. It does not work on a child under six, and it does not cover the owner's own carelessness.

Florida Statute 767.04 does three things most dog bite statutes do only one of. It makes the owner strictly liable. It then reduces that liability if the bitten person was careless. And it gives the owner a specific, narrow, statutory defence built around a sign.

Read the whole section here, quoted directly from the state's own legislative site, with each piece explained.

The statute, in full

Verbatim, from https://www.flsenate.gov/Laws/Statutes/2024/767.04:

"The owner of any dog that bites any person while such person is on or in a public place, or lawfully on or in a private place, including the property of the owner of the dog, is liable for damages suffered by persons bitten, regardless of the former viciousness of the dog or the owners' knowledge of such viciousness."

"However, any negligence on the part of the person bitten that is a proximate cause of the biting incident reduces the liability of the owner of the dog by the percentage that the bitten person's negligence contributed to the biting incident."

"A person is lawfully upon private property of such owner within the meaning of this act when the person is on such property in the performance of any duty imposed upon him or her by the laws of this state or by the laws or postal regulations of the United States, or when the person is on such property upon invitation, expressed or implied, of the owner."

"However, the owner is not liable, except as to a person under the age of 6, or unless the damages are proximately caused by a negligent act or omission of the owner, if at the time of any such injury the owner had displayed in a prominent place on his or her premises a sign easily readable including the words "Bad Dog.""

"The remedy provided by this section is in addition to and cumulative with any other remedy provided by statute or common law."

History, as printed: "s. 1, ch. 25109, 1949; s. 1, ch. 93-13; s. 1155, ch. 97-102."

Statute 767.04 at a glance

The section quoted above does four separate things, and two of them are limits on the sign defence rather than on the owner's liability.

Provision	What it does
Strict liability	Owner is liable regardless of the dog's former viciousness or the owner's knowledge of it
Negligence offset	Liability drops by the percentage the bitten person's own negligence contributed
"Bad Dog" sign defence	Owner is not liable if a prominent, easily readable sign includes the words "Bad Dog"
Sign limit, young children	Defence does not apply to a person under the age of 6
Sign limit, owner's own fault	Defence does not cover damages caused by the owner's negligent act or omission
Cumulative remedy	Section adds to other remedies under statute or common law rather than replacing them

The strict liability core

Read the first sentence again. "Regardless of the former viciousness of the dog or the owners' knowledge of such viciousness." No first-bite exception. No requirement that you knew, or should have known, that your dog was dangerous. A dog with a decade of gentle behaviour behind it gives its owner no protection under this sentence.

That is the same core formula California's Civil Code 3342 uses, and it is a stricter starting position than most jurisdictions in this series. Compare Los Angeles, where the statute reads almost identically, in our coverage of California's strict liability rule.

Coverage extends to lawful presence on the owner's own property, not only public places. The statute then defines what "lawfully" means: performing a legal duty, such as postal delivery, or being present on the owner's invitation, express or implied.

The negligence offset, which Florida has and California does not

This is the clause that separates Florida from the states in this series with a simpler strict liability rule. Verbatim:

This is a proportional reduction, not a bar. If a court finds the bitten person's own carelessness contributed 30 percent to what happened, the owner's liability is reduced by that 30 percent, not eliminated. The statute does not require the bitten person to be blameless; it requires the calculation to be made whenever their negligence was a proximate cause.

What counts as contributing negligence is not defined in this section, and that is exactly the kind of question a court decides on the facts of a specific case rather than something a city guide can answer in the abstract.

The "Bad Dog" sign defence, and its two exceptions

This is the most distinctive part of Florida's statute, and it deserves careful reading because both of its limits matter.

Verbatim:

"the owner is not liable, except as to a person under the age of 6, or unless the damages are proximately caused by a negligent act or omission of the owner, if at the time of any such injury the owner had displayed in a prominent place on his or her premises a sign easily readable including the words "Bad Dog.""

Break that into its actual conditions.

The sign must be displayed in a prominent place, not tucked somewhere a visitor would not see it.

It must be easily readable.

It must include the words "Bad Dog" specifically, per the statute's own text. The section does not describe an equivalent phrase as sufficient.

And it does not protect against everything. Two carve-outs survive even a properly displayed sign:

A person under the age of 6 is excepted from the defence entirely. A prominently displayed "Bad Dog" sign does not protect an owner from liability for a bite to a young child.

Damages proximately caused by the owner's own negligent act or omission are also excepted. The sign protects against strict liability for the dog's behaviour; it does not protect against the owner's own carelessness, such as leaving a gate open when a delivery was expected.

So the sign is narrower than people assume. It is a real, specific, statutory defence, and it has two hard limits that a homeowner should know before relying on it.

What this does not do

The statute closes with a line that matters for anyone thinking this is the whole picture. Verbatim:

"The remedy provided by this section is in addition to and cumulative with any other remedy provided by statute or common law."

This section adds to other remedies, it does not replace them. A bitten person is not limited to this statute if other legal theories apply.

Miami-Dade's own bite reporting, which sits alongside the statute

The civil liability question above is entirely separate from the public health reporting duty Miami-Dade County describes on its own pages. Verbatim from the county's rabies incidents page:

"If you or someone you know has suffered from an animal bite, please report it to the Animal Services Department by completing the Animal Bite Report. All animal bite cases should also be referred to the Florida Department of Health in Miami-Dade County at 305-324-2400."

Two separate destinations for one bite: the county's Animal Services Department, and the Florida Department of Health. Neither of those pages states a post-bite quarantine period, so none is printed here. Our Miami-Dade dog licence guide covers the county's licensing side, and dangerous dogs in Florida covers what happens to a dog once a bite has been investigated under the state's classification process.

How this statute compares to the rest of the corpus

This section is worth reading alongside what other states in this series have done with the same problem, because the differences are not cosmetic.

California's Civil Code 3342 uses nearly identical opening language, "regardless of the former viciousness of the dog or the owner's knowledge of such viciousness," and stops there for civil liability, with a narrow exception for police and military dogs used in the line of duty. It has no comparative negligence clause and no sign defence. Our coverage of California's statute, in the Huntington Beach and Los Angeles guides, quotes it in full.

Massachusetts, where we could read it, follows the same strict liability pattern. But three separate hosts for Massachusetts General Laws were unreachable when this project covered Cape Cod, so no comparable Massachusetts bite statute text made it into that batch at all.

Florida is the only state in this corpus whose bite statute both reduces liability for the victim's own negligence and offers the owner an affirmative sign-based defence. That is a materially different legal environment from a flat strict liability rule, and it is why this guide spends as long as it does on the two carve-outs inside the sign defence rather than treating "Bad Dog sign equals no liability" as the whole story.

What to do if a bite happens

Get medical attention first, then report the incident. Miami-Dade's own report a problem page states: "Call 911 if your injury is severe. After seeking medical care, report the bite incident."

Report it to both destinations, the county's Animal Services Department and the Florida Department of Health in Miami-Dade County.

If you are the dog's owner, do not assume a "Bad Dog" sign settles the matter. It is a real defence with real limits, and whether it applies to your specific facts is a legal question, not a website answer.

If you were bitten, note where you were and how you came to be there. The statute's definition of lawful presence on private property, meaning performance of a legal duty or the owner's invitation, is often the fact that decides the case.

And take legal advice rather than relying on this guide for anything beyond the statute's own words. Nothing here is legal advice.

If the dog involved has previously been classified as dangerous under Florida law, the consequences run further than civil liability. Florida Statute 767.13 makes an attack by a previously declared dangerous dog a criminal matter, a first-degree misdemeanor rising to a third-degree felony where it causes severe injury or death, which our dangerous dogs in Florida guide quotes in full alongside the classification process in Florida Statute 767.11.

Frequently asked questions

Is Florida a strict liability state for dog bites? Yes. Florida Statute 767.04 makes the owner of any dog liable for damages suffered by a person bitten while lawfully in a public place or on the owner's property, regardless of the dog's former viciousness or the owner's knowledge of it.

Does a bitten person's own carelessness matter? Yes. The statute reduces the owner's liability by the percentage that the bitten person's own negligence contributed to the incident, if that negligence was a proximate cause.

Does a "Bad Dog" sign protect an owner from liability? It can, under specific conditions: the sign must be displayed in a prominent place and be easily readable, and must include the words "Bad Dog." It does not protect against a bite to a person under the age of 6, and it does not protect against damages caused by the owner's own negligent act or omission.

Does this apply if I was bitten on the owner's property? Yes, if you were lawfully there. The statute defines lawful presence as performing a duty imposed by state or federal law, such as postal delivery, or being present on the owner's express or implied invitation.

Is there a first-bite exception in Florida? No. The statute applies regardless of the dog's former viciousness or the owner's knowledge of it.

Does this statute replace other legal remedies? No. The statute states that the remedy it provides is in addition to and cumulative with any other remedy available by statute or common law.
