What Evidence Do You Need to File a Dog Bite Lawsuit in Texas?
If you have been bitten by a dog in Texas, you may be entitled to recover compensation for your medical expenses, lost wages, pain and suffering, and other damages. However, recovering compensation requires more than proving you were injured—you must also present evidence showing that the dog owner is legally responsible for the attack. That presents this question: what evidence do you need to file a dog bite lawsuit in Texas?
The strength of your evidence often determines the strength of your case. The more documentation you preserve immediately after the attack, the greater your chances of obtaining a favorable settlement or verdict.
At MLF Legal, our experienced Texas Dog Bite Attorneys help clients gather, preserve, and present the evidence needed to build a strong claim. This guide explains the most important types of evidence in a Texas dog bite lawsuit.
Why Evidence Matters
Texas dog bite claims are commonly based on either:
- The dog’s known dangerous tendencies (often referred to as the “One Bite Rule“)
- Negligence by the dog owner
To recover compensation, you generally must prove:
- The defendant owned or controlled the dog.
- The dog caused your injuries.
- The owner knew or should have known the dog posed a danger, or acted negligently.
- The attack caused measurable damages.

1. Medical Records
Medical records are often the most important evidence in any dog bite claim.
These records establish:
- The nature of your injuries
- The treatment you received
- Future medical needs
- Permanent injuries or scarring
Seek medical attention immediately—even if the bite seems minor. Prompt treatment not only protects your health but also creates documentation connecting your injuries to the attack.
The Centers for Disease Control and Prevention (CDC) warns that dog bites can cause serious infections, nerve injuries, and other complications requiring immediate medical evaluation.
2. Photographs and Videos
Photographs often become some of the most persuasive evidence.
Take pictures of:
- Bite wounds
- Bruising
- Torn clothing
- Blood at the scene
- The dog
- The location of the attack
- Property damage
Continue photographing your injuries during recovery to document:
- Scarring
- Surgical procedures
- Healing progress
- Permanent disfigurement
Visual evidence helps insurance adjusters and juries understand the full extent of your injuries.
3. Witness Statements
Independent witnesses can significantly strengthen your case.
Witnesses may verify:
- How the attack occurred
- Whether the dog was restrained
- Whether the owner attempted to control the dog
- The dog’s aggressive behavior
- Your actions before the attack
If possible, obtain:
- Names
- Phone numbers
- Email addresses
Witness statements often become valuable evidence if liability is disputed.
4. Animal Control Reports
Report every dog bite to local animal control or law enforcement.
These reports may document:
- The dog’s vaccination status
- Prior bite history
- Prior complaints
- Dangerous dog designations
- Owner information
- Investigation findings
The Texas Department of State Health Services recommends reporting animal bites to protect public health and assist with rabies investigations.
5. Veterinary Records
Veterinary records may reveal:
- Vaccination history
- Prior aggressive behavior
- Breed information
- Ownership records
In some cases, these records help establish that the owner knew the dog had dangerous tendencies.
6. Insurance Information
Many dog bite claims are paid through homeowner’s or renter’s insurance.
Important documents include:
- Homeowner’s insurance declarations
- Renter’s insurance policies
- Umbrella liability policies

7. Proof of Financial Losses
Keep records of every expense related to your injuries.
Examples include:
- Medical bills
- Prescription receipts
- Physical therapy invoices
- Mileage to medical appointments
- Lost wage documentation
- Employer verification
- Future treatment estimates
These records help establish your economic damages.
8. Expert Testimony
In serious dog bite cases, expert witnesses may be necessary.
Experts may include:
- Physicians
- Plastic surgeons
- Psychologists
- Vocational rehabilitation specialists
- Economists
- Animal behavior experts
Expert testimony can explain:
- Future medical care
- Permanent disabilities
- Emotional trauma
- Loss of earning capacity
- Animal behavior and foreseeability
9. Prior Dog Bite History
One of the strongest forms of evidence is proof that the dog previously displayed aggressive behavior.
Evidence may include:
- Previous bites
- Neighbor complaints
- Animal control investigations
- Prior lawsuits
- Witness testimony
Texas courts recognize that evidence of a dog’s dangerous propensities may establish liability under Marshall v. Ranne, 511 S.W.2d 255 (Tex. 1974).
10. Preserve Evidence Immediately
Do not wait.
Evidence can disappear quickly.
You should:
- Save torn clothing.
- Preserve shoes.
- Keep damaged personal property.
- Save photographs.
- Keep copies of every medical bill.
- Write down your memory of the attack while it is fresh.
Small details often become important months later.
