Protection Dog Laws By State

Each box restates the rule in a sentence or two and links the primary text behind it; where a box cites two texts, the second is in the sources at the foot of the page. The state name links to our page for that state, which quotes the law at length and covers what a table cannot: the cases, the exceptions, insurance and the local codes. For Texas, the cases are in our Texas dog bite law guide, linked at the end of this page.

A dash means our page for that state cites no rule of that kind. It does not mean the state has none. A box states state law unless it names a city or county, and a rule in one town says nothing about the next.

The date on every entry is 15 October 2026, when each was re-read at its source. Statutes and ordinances change, and where this table and the current text disagree, the text wins. We train dogs; we are not lawyers, and nothing here is legal advice.

Who answers for a bite

California, Florida and New Jersey have statutes that make an owner liable for a bite regardless of the dog’s former viciousness. Of those three, only Florida lets a prominent “Bad Dog” sign on the premises defeat that liability, except for a child under six or where the owner’s negligence caused the damage. Illinois reaches injuries rather than bites, through an Animal Control Act that its courts say was passed partly to drop the need to prove what the owner knew; one appellate decision, Hayes v. Adams (2013), still held that the Act does not impose strict liability on a legal owner, in a case where the owner had handed the dog’s care, custody and control to a veterinary clinic. Colorado’s statute reaches only serious bodily injury or death, pays economic damages only, and has exceptions of its own, among them posted signs on the owner’s property.

Our pages for Texas, New York, Georgia and North Carolina cite no statute of that kind, and there what the owner knew, or what the dog had already done, carries more weight: Texas through a 1974 court rule for animals the owner has reason to know are abnormally dangerous, with negligence for the rest; New York through its vicious-propensity rule, with negligence claims allowed since 2025; Georgia through a vicious-animal statute its courts read to require knowledge; and North Carolina through strict liability only for a dog that meets its dangerous-dog definition, with negligence in confining or restraining the dog for the rest.

Our reading, not a court’s, for a household that keeps a bite-trained dog: in California, Florida and New Jersey, one bite in the wrong place can be enough, so the daily discipline of gates, leads and who answers the door is the protection. In Texas, New York, Georgia and North Carolina, an incident becomes part of the dog’s record and of what the owner can be shown to have known, which is why a near miss deserves the same attention as a bite.

Training is almost never the test

Every state dangerous-dog test in the table turns mainly on what a dog has done or how it behaves. As the table states them, only two make training a ground, and the training they name is fighting: Colorado’s covers a dog that engages in or is trained for animal fighting, and North Carolina’s a dog owned, harbored or trained for dog fighting. Georgia’s mentions training only to spare a hunting, herding or predator-control dog that kills a pet while working or training. New Jersey’s potentially-dangerous test once covered a dog “trained, tormented, badgered, baited, or encouraged” to attack, and a 2019 amendment deleted that ground. Fighting aside, what these definitions look at is the dog’s conduct.

Where trained dogs are named, it is mostly local

Of the eight guard-dog boxes in the table, six hold only city or county codes. California and Illinois are the two at state level. California’s definition of a guard or attack dog takes in any dog trained to protect, defend or guard a person or property, and any schutzhund, and comes with a microchip duty. Illinois exempts rabies-vaccinated sentry, guard and police-owned dogs performing duties as expected from its dangerous-dog section; a separate Illinois law, the Animal Welfare Act, defines a guard dog for its own purposes as a commercial-establishment dog and excludes personally owned pets that also provide security. Some local rules are not limited to businesses: nothing in Woodbridge’s registration rule exempts a home, New York City says its guard-dog registration covers individuals as well as businesses, and Charlotte’s rule covers dogs trained “to any extent” to bite or attack, a definition that names personal security. Others stop at nonresidential premises: Miami-Dade, Palm Beach County and Mahwah license or permit guard dogs only there.

Our city pages go further for four places: Los Angeles, with its own sentry dog license; Denver, which also covers Cherry Hills Village; Palm Beach County; and Westchester County, where the rule changes from one municipality to the next.

The bill after a finding

Texas and Florida require at least $100,000 of liability cover for a dangerous dog (Texas also accepts other financial responsibility, within 30 days of the owner learning the dog is dangerous), Georgia $50,000 for a dog classed as vicious, and New York lets a court order insurance of up to $100,000. New Jersey’s text, as reprinted in a 2020 bill, lets the municipal court require insurance in an amount it sets. Colorado, after a conviction, adds a $50 microchip license fee to its confinement and disclosure orders, and Illinois starts with a $50 public safety fine.

Colorado, Illinois and New York bar homeowners insurers from refusing, cancelling or surcharging a policy over a dog’s breed alone, and all three still let an insurer act once a particular dog is known, found or declared to be dangerous. Breed comes off the table; the dog’s record stays on it. Our pages for the other six states cite no statute of this kind, so there the question for your agent is how your insurer treats a dog trained in bite work, and our homeowners insurance guide sets out what to ask.

The town. Most of the guard-dog rules above are local, and the next town over may have none or a stricter one. The clerk or the animal control office holds the current text for your address.

The date. Dangerous-dog law moves: New Jersey amended its definitions in 2019, and Florida added its $100,000 insurance requirement in 2025. Our state pages say when each text was read, and this table was re-read on 15 October 2026.

Your facts. Whether a statute reaches a dog trained in bite work, or a household like yours, is a question for a lawyer licensed in your state. The table can tell you which question to ask, not the answer.
