If you’ve been bitten or attacked by a dog in Texas, you may have heard someone say, “It’s the dog’s first bite, so the owner isn’t responsible.” That is not an accurate description of Texas dog-bite rule.
Texas is commonly described as a “one-bite rule” state, but the rule is more complicated than the name suggests. A dog owner may potentially be responsible when the owner knew or had reason to know that the animal had dangerous propensities. In addition, an injured person may have a claim based on negligence, including negligent handling or failure to reasonably control the dog.
This distinction can be extremely important.
If you were injured by a dog in San Antonio or elsewhere in Texas, you should not assume that you have no legal claim simply because the dog had never bitten anyone before.
This article explains the Texas one-bite rule, what an injured person may need to prove, what evidence can establish that a dog was dangerous, and why a first bite does not necessarily end the analysis.
Yes, but the phrase can be misleading.
Texas follows common-law principles governing liability for injuries caused by domestic animals. The Texas Supreme Court’s 1974 decision in Marshall v. Ranne is the foundation for the state’s approach. The case involved a vicious hog rather than a dog, but the court addressed liability for domestic animals with known dangerous propensities.
The Texas Bar has explained the rule as providing two potential avenues for an injured person:
That is why the expression “one free bite” can be misleading.
A dog does not receive an automatic legal exemption from responsibility simply because it has never bitten anyone before.
At its simplest, the traditional one-bite principle asks whether the owner knew or had reason to know that the animal had dangerous tendencies.
That knowledge can come from many things.
It does not necessarily require a previous bite.
For example, an owner may have reason to know that a dog presents a danger if the dog has previously:
The specific facts matter.
A previous bite is obviously important evidence, but it is not necessarily the only evidence capable of establishing that the owner knew or should have known about the dog’s dangerous behavior.
This is probably the most important point for Texas dog-bite victims.
Imagine that a dog has never actually bitten a person.
However, suppose the dog has repeatedly:
Then the owner may have had information suggesting that the dog presented a danger even though there had never been an actual bite.
That evidence can become important when determining whether the owner knew or should have known about the dog’s dangerous tendencies.
The State Bar of Texas specifically notes that the Texas rule does not necessarily protect an owner simply because the dog has not previously bitten someone. A victim may potentially recover under a negligence theory even when the animal has not previously been classified as dangerous or vicious.
Possibly.
This is one of the most important questions an injured person should ask.
Texas recognizes negligence as a potential basis for liability in dog-attack cases. An injured person may potentially establish that the owner failed to use reasonable care in handling or controlling the animal and that the failure caused the injury.
For example, consider a dog that has never previously bitten anyone.
The owner knows the dog frequently escapes from the yard because the backyard gate does not latch properly.
The owner leaves the dog outside.
The dog escapes, runs into the street and attacks a pedestrian.
The fact that the dog had never bitten anyone before does not necessarily answer the negligence question.
A lawyer would want to investigate:
Those facts may be more important than whether the dog had a previous bite.
The phrase dangerous propensity refers generally to behavior that indicates an animal presents a particular danger.
The owner does not necessarily have to know:
“My dog is going to bite someone.”
Instead, the evidence may show that the owner knew or had reason to know that the dog had characteristics or behavioral tendencies that could create a foreseeable risk of injury.
For example, evidence might include:
A dog that has repeatedly lunged at strangers may present a different legal situation than a dog with no history of aggressive behavior.
An attempted bite can be important even if the dog never actually broke someone’s skin.
Depending on the circumstances, aggression toward other animals may provide evidence concerning the dog’s behavior.
Complaints from neighbors or other people can potentially establish that the owner was aware of aggressive behavior.
Animal-control records may provide important evidence about previous incidents.
Communications from professionals may become relevant if they demonstrate that the owner was aware of behavioral problems.
One of the biggest issues in a Texas dog-bite case may be proving what the owner knew before the attack.
That is why investigating the history of the dog can be so important.
Potential evidence may include:
For example, suppose a neighbor previously texted the owner:
“Your dog charged my daughter again today.”
That message could potentially be very different from a situation in which the owner had never received any warning about the dog’s behavior.
This is a common response after an attack.
An owner may genuinely believe that the dog had never behaved aggressively before.
But the statement doesn’t necessarily resolve the legal issue.
An investigation may uncover information the owner forgot about or did not disclose.
For example:
That’s one reason serious dog-bite cases should not necessarily be evaluated solely on the owner’s version of what happened.
A loose dog can create an entirely different set of questions.
Suppose you are walking through your San Antonio neighborhood when a dog runs out of an open gate and attacks you.
A lawyer may want to determine:
San Antonio Animal Care Services states that dogs are not permitted to roam off their owner’s property within the city. The city also investigates reports involving dangerous or aggressive dogs.
That does not mean that every violation automatically establishes civil liability. But it can be an important fact when investigating an injury claim.
That fact can matter, but it doesn’t automatically defeat a claim.
Texas recognizes potential negligence claims in addition to the traditional dangerous-animal theory.
For example, consider a dog that has always been friendly.
The owner brings the dog to a crowded public event without a leash or other reasonable control.
The dog suddenly runs toward a person, knocks the person down and causes a serious injury.
The legal analysis may focus on the owner’s conduct rather than simply asking whether the dog had previously bitten anyone.
The question becomes whether the owner acted reasonably under the circumstances and whether a failure to do so caused the injury.
This distinction is important.
The focus is on the animal’s known dangerous tendencies.
The injured person may need to establish that the owner knew or had reason to know the animal presented a danger.
The focus is on the owner’s conduct.
The questions may include:
The Texas Bar describes both of these potential paths to recovery.
This is why simply asking, “Has the dog bitten anyone before?” may not be enough to evaluate a Texas dog-bite case.
Texas also has statutory provisions dealing with dangerous dogs.
San Antonio Animal Care Services explains that a dog can be identified as dangerous when it makes an unprovoked attack causing bodily injury outside an enclosure reasonably certain to prevent the dog from escaping, or when it commits certain other unprovoked acts causing a person to reasonably believe it will attack and cause bodily injury.
If a dog has been involved in an incident that meets the applicable statutory criteria, the investigation may involve more than the traditional one-bite analysis.
This can make it important to determine whether the dog had previously been the subject of an animal-control investigation.
If you were attacked by a dog, reporting the incident isn’t only about satisfying public-health requirements.
It can also create an official record of the event.
San Antonio Animal Care Services states that animal bites or scratches that break the skin must be reported to the local rabies-control authority. Within San Antonio city limits, Animal Care Services handles these reports.
San Antonio also maintains information concerning dangerous and aggressive dogs and investigates qualifying reports.
If you’re involved in a serious dog-bite claim, those records may become important evidence.
If you’ve suffered a dog bite, your immediate priorities should be safety and medical care.
Don’t risk another attack trying to obtain evidence.
Dog bites can cause puncture wounds, infection, nerve damage, tendon injuries and significant scarring.
If you’re within San Antonio city limits, Animal Care Services directs residents to report animal bites through 311 or 210-207-6000.
Take photographs immediately and continue documenting the healing process.
Obtain contact information whenever possible.
Doorbell cameras and security cameras may capture the attack or earlier incidents involving the dog.
Obtain the owner’s name, contact information, and homeowners/renters insurance information if you can do so safely.
Don’t throw away clothing damaged during the attack.
The fact that the dog had never previously bitten anyone does not necessarily end the legal analysis.
San Antonio dog-bite victims should be aware of the distinction between city and county animal-control authorities.
Within San Antonio city limits, Animal Care Services handles animal-bite investigations and directs residents to report bites through 311.
But San Antonio Animal Care Services does not handle animal-related services in unincorporated Bexar County or other municipalities within Bexar County. The city directs Bexar County residents to Bexar County Animal Control at 210-335-9000.
That distinction can matter if your attack occurred in an area such as:
The appropriate local authority may depend on exactly where the attack occurred.
This is often where the investigation becomes particularly important. A dog owner isn’t likely to volunteer: “Yes, my dog tried to bite my neighbor three months ago.” Instead, evidence may need to come from other sources.
An attorney investigating a serious dog-bite case might look for:
Someone else may have been attacked or threatened.
Neighbors sometimes know considerably more about an aggressive dog than the owner realizes.
Previous complaints may establish a history of problems.
Records may contain information about behavioral issues.
Owners and neighbors may have discussed previous incidents.
Owners sometimes post photographs or comments describing their dog’s behavior.
Previous incidents may have been captured by cameras.
Something the owner said immediately after the attack may be particularly important.
Provocation can become an issue in a dog-bite case.
The circumstances matter.
For example, there is a significant difference between:
An insurance company may attempt to characterize the victim’s actions in a way that minimizes its responsibility.
That’s another reason to preserve witness statements, photographs and video whenever possible.
Potentially.
Texas follows a comparative-responsibility system, and the effect of a plaintiff’s own conduct depends on the circumstances and applicable law.
You should therefore not assume that an allegation such as: “You shouldn’t have been near the dog” automatically eliminates your claim.
The facts surrounding the encounter need to be examined.
The damages available in a Texas personal-injury case depend on the facts.
A serious dog attack can potentially result in damages associated with:
The more serious and permanent the injury, the more important it may be to thoroughly document the claim.
A facial dog bite, for example, can involve not only the initial emergency treatment but also future scar treatment, reconstructive procedures and psychological consequences.
Texas generally provides a two-year limitations period for personal-injury claims under Texas Civil Practice and Remedies Code § 16.003.
But you shouldn’t interpret that as a reason to wait.
Evidence can disappear long before the two-year deadline.
For example:
There may also be exceptions affecting limitations in particular circumstances.
If you’ve suffered a significant injury, it is better to have the deadline evaluated by a Texas attorney rather than relying on a general rule.
When contacting an attorney, be prepared to explain:
Don’t worry about making your story sound perfect.
Tell the attorney what actually happened.
An attorney can evaluate both the favorable and unfavorable facts.
That does not necessarily mean you have no claim.
You may never have personally encountered the dog before.
The relevant question may be what the owner knew about the dog’s behavior before the attack.
For example, you might be a delivery driver, postal worker, neighbor, contractor or visitor encountering the dog for the first time.
The owner may nevertheless have known about prior aggressive behavior.
Not necessarily.
A minor injury that heals quickly may not require an attorney.
But you should consider speaking with a Texas personal-injury attorney if the attack caused:
You should also consider legal advice if the dog owner or insurance company disputes responsibility.
If there’s one thing to remember from this article, it’s this:
A dog’s lack of a previous bite does not automatically mean that the owner cannot be held responsible for your injuries.
Texas law recognizes potential liability based on both known dangerous propensities and negligence.
The circumstances surrounding the attack matter.
If you were seriously injured, an attorney can investigate:
If you or your child has been seriously injured by a dog, you may have legal options even if the dog had never bitten anyone before.
The Texas one-bite rule is more complicated than the common saying that every dog gets “one free bite.”
