Legal Standards in Dog Bite Injury Litigation
Texas does not have a specific statute governing dog bites. Thus, courts rely on common law principles, mainly the “one bite rule” and negligence law.
The One Bite Rule
In Texas, an owner may only be held strictly liable if they knew (or should have known) that their dog had dangerous tendencies. For instance, if a dog previously bit someone or exhibited threatening behavior, that prior knowledge can form the basis for liability. That is the case even if the owner didn’t expect a serious attack.
Proving Negligence
When there’s no history of aggression, victims can still pursue claims under negligence per se. A negligence-based dog bite injury case requires proving that:
- The owner failed to act as a reasonable dog owner would by violating a statute
- That failure led to the bite or attack
- The victim suffered injuries and damages
Negligence may include letting a dog off-leash in public, ignoring leash laws, or failing to secure a dog known for unpredictable behavior.
Who Can Be Held Liable in a Dog Attack Lawsuit?
The dog’s owner is typically the first person considered responsible. However, others may also be held liable depending on the circumstances.

Common Defendants in Dog Bite Lawsuits
- Dog Owners. Held accountable when they knew or should have known about the dog’s aggression.
- Landlords. In some cases, landlords who allowed a dangerous dog to remain on their property may be found partially liable. In Texas, you must prove the landlord had actual knowledge that the dog had abnormally dangerous propensities.
- Caretakers or Dog Walkers. Temporary handlers may be liable if the bite occurred while the dog was under their supervision.
- Property Owners. If an attack happened on private property due to poor fencing or negligence, the property owner may be brought into the lawsuit.
Key Factors That Influence Liability
Several elements influence the outcome of dog bite injury litigation. Courts look at more than just who owned the dog.
Severity of Injury
The seriousness of the bite affects compensation. Deep punctures, nerve damage, facial injuries, and infections typically result in larger settlements.
History of Aggressive Behavior
Evidence of past aggression establishes that the owner had reason to believe the dog was dangerous. Examples may include prior bites, growling, or official warnings.
Violation of Laws or Ordinances
Violating local leash lawsor containment requirements may help prove negligence per se.
Behavior of the Victim
The victim’s actions also matter. If they provoked the dog or entered private property unlawfully, their recovery may be reduced or denied entirely.
What Compensation Can Be Recovered?
Victims of dog bites may be entitled to compensation for:
- Medical expenses. ER visits, surgery, therapy, and medications
- Lost wages. Income lost during recovery
- Pain and suffering. Physical pain and diminished quality of life
- Disfigurement. Compensation for scarring or lasting visible injuries
- Emotional distress. Anxiety, PTSD, and mental trauma following the attack
In particularly severe cases, O’Hara Law Firm has helped clients secure confidential seven-figure settlements, especially when there’s proof of repeated negligence or previous incidents involving the same dog.
