Texas Dog Bite Law For Protection Dog Owners

Neither label fits cleanly. Texas has no strict-liability dog-bite statute (it is missing from the Michigan State table of the roughly 36 states that have one); the rule comes from a 1974 Texas Supreme Court case that makes an owner strictly liable when they knew or had reason to know the animal was abnormally dangerous, and treats everything else as negligence. In a 2012 negligent-handling case, a Houston appeals court wrote that a dog trained to bite has that kind of propensity. No court has held a protection dog owner strictly liable on that basis, but the owner of one should plan as if a court could treat the dog as abnormally dangerous from the day it arrives.

Separately, Chapter 822 of the Health and Safety Code can make a serious bite a felony, put the dog in front of a judge who may order it destroyed, or have it declared a dangerous dog, with registration, restraint and insurance duties attached.

The leading Texas case on who pays when an animal hurts someone is not about a dog. In Marshall v. Ranne, two men who both lived in Dallas owned neighbouring farms in Van Zandt County. Ranne’s boar got loose and spent weeks on Marshall’s land. By Marshall’s account it charged him ten to twelve times, held him prisoner in his outhouse several times, and attacked his wife on four or five occasions. On the day he was hurt he left a note on Ranne’s gate that read in part, “your boar has gone bad,” then walked toward his pickup, heard a noise, turned, and put out a hand. The boar bit it severely.

The jury found Marshall contributorily negligent (his fence had gaps, and he had a gun in the house and had not used it on the hog), and also found that he had voluntarily assumed the risk of the hog. The trial court entered judgment for Ranne, and the court of civil appeals affirmed on the assumption-of-risk finding. The Texas Supreme Court reversed. It noted that Texas courts had been treating animal cases sometimes as negligence and sometimes as strict liability, and it picked one. Suits for damage done by vicious animals “should be governed by principles of strict liability,” and the court adopted the Restatement’s wording: a possessor of a domestic animal “which he has reason to know has dangerous propensities abnormal to its class, is subject to liability for harm caused thereby to others, except trespassers on his land, although he has exercised the utmost care to prevent it from doing the harm.”

Three phrases in that sentence decide most of what follows for a protection dog owner.

“Reason to know.” Ranne’s jury refused to find he actually knew the hog was vicious, but found he should have known. The court said there is “no essential distinction” between the two. Proof that you were told is not required; proof that a reasonable person in your position would have concluded it is enough.

“Although he has exercised the utmost care.” Under the strict rule, the owner’s own care is not a defense: a good fence and a good leash do not answer the claim. The court also held that the injured person’s ordinary carelessness is not a defense, because the policy “places the full responsibility for preventing the harm upon the defendant.” That was the law of 1974. How later Texas rules on sharing fault between the parties interact with it is precisely the kind of question to put to a lawyer and not to us.

The defense that survived. The court did not leave the owner with nothing. “Voluntary assumption of risk, if established, would be a valid defense,” it held. Marshall lost on that point in the lower courts and won it in the Supreme Court only because he had no free choice: he could stay a prisoner in his own house or cross his own land to his truck, and the court called that “a choice of evils, both of which were wrongfully imposed upon him by the defendant.” A person who freely chooses to confront a dog they know is dangerous stands differently. Whether that defense fits any real bite is, again, a lawyer’s question.

“Except trespassers on his land.” The strict rule, as the court quoted it, does not run in favour of a trespasser on the owner’s land. That is narrower than it sounds. It is not a licence to injure a trespasser, it says nothing about the person on the public sidewalk, and it does not touch the invited visitor at your front door.

The court also kept the other road open. “All animals are not vicious,” the opinion says, and the possessor of a non-vicious animal “may be subject to liability for his negligent handling of such an animal.” That sentence is where the rest of Texas dog bite law hangs from. (On rehearing the court sent the case back over the size of the damages award; the liability rule stood.)

“Texas is a one-bite state” is shorthand for the knowledge requirement, and it misleads people in two directions. The rule never required a bite: it requires reason to know. And for a dog trained in bite work, a court could find the knowledge was supplied before the dog ever reached your house.

The clearest statement comes from a case about a police dog, and it was not a strict-liability case. In City of Houston v. Jenkins, a Montgomery County deputy was bitten in 2007 by a Houston Police Department dog named Rudy. The search was over and the handler was walking Rudy back to his car on a 15-foot leash; he had stopped to shake hands with another officer when the dog took the deputy behind the knee. Rudy had bitten a SWAT officer during training and had bitten his own handler for a correction. The Fourteenth Court of Appeals in Houston, applying the rule from Marshall, wrote: “A dog that has been trained to bite or that has a history of doing so has dangerous propensities abnormal to its class.” It cited the Restatement comment that “the great majority of dogs are harmless,” and another noting that even an attempt to attack human beings is enough to bring the owner within the rule.

Context matters here. Jenkins sued for negligent handling, and the city pointed out that he had raised no strict-liability argument. The court agreed he had not alleged liability simply for keeping the dog, and said “the same dangerous propensities that support strict liability also are a factor in determining foreseeability in negligent-handling cases.” It used the propensity language to find “more than a scintilla of evidence” that Rudy was a dangerous animal and that his handler knew it, which was enough to keep the claim alive. It held nobody strictly liable.

Read that sentence with an or in the middle of it. It does not say trained to bite and has bitten, so training alone fits within its wording. On the facts before it, though, Rudy also had a bite history, so we do not know what that court would have done with a trained dog that had never bitten.

The opinion also anticipated the argument a private buyer might make — that a trained working dog is a professional tool and sits outside the ordinary rules. The city made a version of that argument about police dogs, and the court rejected it: Rudy “is still a dog subject to human control. A private person could purchase the same dog from the same seller and would not be exempt from leash laws or the duty to control the animal simply because the dog has specialized training.” The Texas Supreme Court denied review in August 2013.

Be precise about what that case is. It is one intermediate appellate court, deciding governmental and official immunity questions about a city in a negligent-handling suit, on facts that included a dog with a bite history. Strict liability was not pleaded. It is not a holding that every protection dog is abnormally dangerous as a matter of law. But it is the sentence a lawyer on the other side will read to a judge, and we would plan as if a court could follow it.

Here is the uncomfortable part for a buyer. The more convincing the dog’s training, the stronger the knowledge argument against you. Everything we argue in will a protection dog bite without a suit — that a properly finished dog engages a person in street clothes, not a sleeve — is also, read in a courtroom, evidence a lawyer can offer that you knew what the dog was trained to do. Buying that capability weakens the one-bite argument, and we would not count on it. Pick the capability, and then manage it as an owner a court may well consider on notice.

Strict liability is not the only claim. Texas courts treat negligent handling as a separate road open whether or not the dog is abnormally dangerous, and Jenkins set out its elements plainly: the defendant owned or possessed the animal, and caused the injury by breaching the duty to use reasonable care to prevent it from injuring others.

The Texas Supreme Court added a piece in 2008 that matters more to protection dog owners than to anyone. In Bushnell v. Mott, a woman delivering health products knocked on a mobile-home door. When the owner opened it, three dogs pushed out and bit the visitor on her legs, arms, back and shoulder. She said the owner did nothing to stop it and that she “never once heard [Mott] scold the dogs.” The trial court granted summary judgment for the owner, and the court of appeals affirmed on the ground that nothing showed she knew the dogs were dangerous.

The Supreme Court reversed. Even for a dog not known to be vicious, it held, an owner owes a duty to try to stop an attack after it has begun, quoting the Restatement: the owner of a dog “is liable if he sees his dog or cat about to attack a human being ... and does not exercise reasonable care to prevent it from doing so.”

Think about what that duty looks like for the owner of a trained dog. The dogs in Bushnell were not known to be vicious, and nothing in the opinion suggests their owner had any trained way to stop them. A dog you buy should come with a trained release — the out. Ask to see it work cold, and ask who in your household will be shown how to use it. The law asks for reasonable care to stop an attack once it starts. For the owner of a bite-trained dog, a reliable out is the most obvious way to meet that standard, though no court has said so, and we are not lawyers and will not predict how a jury would weigh it. Our training levels page explains why the out is the behaviour to test first when you are shopping, and how to ask for it cold and after a hard engagement.

Yes, for a serious one. Section 822.005 of the Health and Safety Code, titled “Attack by Dog,” makes it a crime for an owner in either of two situations. The first is the one that matters to almost every owner:

The owner “with criminal negligence ... fails to secure the dog and the dog makes an unprovoked attack on another person that occurs at a location other than the owner’s real property or in or on the owner’s motor vehicle or boat and that causes serious bodily injury ... or death to the other person.” The second applies to an owner who already knows the dog is a dangerous dog, and reaches attacks anywhere other than a proper secure enclosure. Either way it is a third-degree felony, or second-degree if the person dies, and the court may order the dog destroyed.

Why it is called Lillian’s Law. On the Saturday after Thanksgiving, 26 November 2005, Lillian Stiles, 76, was attacked by a neighbour’s six dogs in her own front yard in San Gabriel, just outside Thorndale in Milam County, and bled to death there. The county’s prosecutor later wrote about the case for Texas prosecutors: the dangerous-dog statute could not be used because the dogs had no documented history, the case was tried on a criminal-negligence theory, and in March 2007 the owner was found not guilty. The prosecutor credits the case and its coverage with helping pass House Bill 1355 in the 80th Legislature, which took effect on 1 September 2007. As the prosecutor put it, “The new law does not require that the owner know his dog is aggressive or dangerous.”

What the crime actually is. The offense is your conduct, not the dog’s. When the Court of Criminal Appeals upheld the statute in Watson v. State — a 2008 Stephens County case in which a seven-year-old boy was killed by a rural family’s dogs after they got off the property, and both owners were sentenced to seven years — it said so directly: “Failure to secure a dog is the conduct prohibited by the statute.” “Secure” is defined in section 822.001 as taking the steps “a reasonable person would take to ensure a dog remains on the owner’s property, including confining the dog in an enclosure that is capable of preventing the escape or release of the dog.” Criminal negligence, under Penal Code section 6.03, is failing to perceive a substantial and unjustifiable risk in a way that is “a gross deviation from the standard of care that an ordinary person would exercise.”

Notice the shape of the first offense. It does not reach a bite in your own yard, in your house, or in your truck. It is written for the dog that got out. That is why the most important protection-dog equipment you will ever buy is not a bite sleeve. It is a gate that latches by itself.

Section 822.006 lists defenses to the felony. Most cover people who handle dogs for a living — veterinarians, shelter staff, peace officers, corrections and police dog handlers, assistance-dog users, search-and-rescue teams, organised kennel-club events, lawful hunting and ranch work. Three are worth a protection dog owner’s attention.

The trainer defense does not travel with the dog. Subsection (c) covers “a dog trainer or an employee of a guard dog company under Chapter 1702, Occupations Code” who has temporary custody of the dog “in connection with that position.” It protects a trainer while the dog is in training. The day the dog is yours, it covers nobody in your household.

The person attacked was committing certain crimes. Subsection (e) is a defense if the person attacked was engaged in conduct prohibited by Penal Code chapters 19, 20, 21, 22, 28, 29 and 30. In plain terms those are homicide; kidnapping, unlawful restraint and smuggling of persons; sexual offenses; assaultive offenses; arson and criminal mischief; robbery; and burglary and criminal trespass. That is the closest the statute comes to describing what a protection dog is for. It is a defense to a prosecution, not a ruling in advance, and it does nothing about a civil suit.

The leash. Subsection (i) is a defense if “the person’s dog was on a leash” and the person was in immediate control of it, or was making “immediate and reasonable attempts to regain control.” Read with the location limit above, the statute draws a simple map: inside your fence, secure the property; outside it, the leash is in your hand.

Under this part of the statute, only through a court and only after a death or a serious bodily injury — though the dangerous-dog rules further down have routes of their own. The process is fast. Under section 822.002, on anyone’s sworn complaint that a dog caused a death or serious bodily injury, and a showing of probable cause, a justice, county or municipal court “shall” order the dog seized. The hearing must be held within ten days of the warrant.

What the court may do depends on the outcome of the attack. Under section 822.003, if the dog caused a death, the court “shall order the dog destroyed.” If it caused serious bodily injury, the court “may” order it destroyed — and the statute then lists situations in which it may not. The list is short and specific:

So does a “Beware of Dog” sign matter in Texas? For this hearing, yes: notice of a dog is one of the written conditions of the first exception. It is not a shield against the civil rule or the felony, and the protection-dog exception needs everything else on that line to be true as well, including an enclosure the dog cannot leave on its own and an adult or older child who was trespassing.

The exceptions are all written about serious bodily injury. The words for a death are “shall order the dog destroyed,” and the statute lists no exception to them.

The dangerous-dog rules are a fifth system. They start with animal control, but a court can hear the dispute (section 822.0423), and an appeal to county court carries a jury trial on request (section 822.0424). Under section 822.041, a dog is dangerous if, outside an enclosure reasonably certain to keep it in, it makes an unprovoked attack that causes bodily injury, or commits unprovoked acts that make a person reasonably believe it will attack. No bite is required for the second. The registration, restraint, $100,000 insurance requirement and appeal deadlines that follow are set out step by step in our guide to protection dogs and homeowners insurance, because the insurance requirement is where they bite hardest. Four details that guide does not dwell on:

You can trigger the clock yourself. Under section 822.042(g), an owner “learns” they own a dangerous dog not only when animal control or a court says so, but when “the owner knows of an attack” of the kind the definition describes. The thirty days can start on the afternoon of the incident, with no letter in the post.

In the largest counties, the dog goes in first. In a county of more than 2,800,000 people, or one that has opted in, anyone may report an incident to a court, and the owner must deliver the dog to animal control within five days of notice, and it may be impounded until a court decides whether it is dangerous.

The penalties for an owner are separate from the felony. If a dog already found dangerous makes an unprovoked attack outside its enclosure and causes bodily injury, the owner commits a Class C misdemeanor and the court may order the dog destroyed. Failing to comply with the requirements is its own Class C offense, Class B on a repeat conviction.

Local rules can add, but not by breed. Section 822.047 lets a city or county put further requirements on dangerous dogs only if they are “not specific to one breed or several breeds of dogs” and are more stringent than the state’s. A Malinois is not a dangerous dog under Texas law because it is a Malinois. It becomes one by what it does.

Your insurance carrier. Every civil claim on this page ends up being paid by a policy or by you. What to ask, and why the answer has to be in writing, is covered in the insurance guide.

A Texas lawyer, for an hour. Not because you expect trouble, but because the questions are specific to your property and your household: whether your fence and gate meet the enclosure language above, who in the family may handle the dog in public, what your city adds to the state rules, and what you would do in the first hour after an incident. That conversation is cheap before and expensive after.

A fully trained dog from us is delivered and worked in your own house, with your family present. Ask us to show you the release before anything else on that visit; it is the behaviour the Bushnell duty points straight at. The rest is for your household to settle before that day: where the crate sits relative to the front door, and who is allowed to hold the leash in public. If there are children in the house, read protection dogs and children before that day, not after it. If the dog will live outside Texas, none of this transfers; the law is where the bite happens, which is one of the reasons for our guide to buying out of state. How a bite is handled in some other states is on our state pages on owning a protection dog in California, Colorado, Florida, Georgia, Illinois, New Jersey, New York and North Carolina.

City and county ordinances. Chapter 822 expressly allows local leash and registration rules and stricter dangerous-dog rules. Check your own city and county; this page does not summarise any local ordinance.

Dogs and livestock. A dog that goes after stock is governed by a different subchapter, under which a witness to the attack may kill the dog and owes its owner nothing for it. Our Hill Country page walks through it.

Damages, deadlines and procedure. How much a claim is worth, how long someone has to bring it, and how fault is shared between the parties are lawyers’ questions, and we have not tried to answer them.

Anything after 8 October 2026. Statutes are amended and courts decide new cases. Chapter 822 has been amended several times since 2007. Check the current text before you rely on any of it.
