Texas Dog Bites: The "One Bite Rule" vs. Negligence

I’ve had clients come to me after a dog bite feeling completely overwhelmed. Not only are they dealing with the physical pain and the medical bills, but they’ve often been told, “Texas is a 'One Bite' state—if the dog hasn’t bitten anyone before, you’re out of luck.”

I’m here to tell you: That is a myth.

While Texas law is unique, it doesn’t give a dog one "free" pass to hurt someone. It just means we have to look at the case through two different lenses: Strict Liability and Negligence.

1. The "One Bite Rule" (Strict Liability)

This path is all about what the owner knew before you got hurt. In 1974, the Texas Supreme Court (in a case called Marshall v. Ranne) established that if an owner knows their dog has "vicious propensities," they are strictly liable.

Despite the nickname, the dog doesn't actually have to have bitten someone before. If the dog has a history of lunging, snapping, or aggressive growling—and the owner knew it—the "One Bite" shield is pierced. At that point, it doesn't matter if they had the dog in a triple-locked cage; if the dog gets out and bites, they are responsible.

A quick note on breeds: People often ask me if certain breeds like Pit Bulls are automatically considered "dangerous." In Texas, the law looks at the individual dog, not the breed. We have to prove that specific dog was aggressive, regardless of what kind of dog it was.

2. The "Escaped Dog" Path (Negligence)

This is where most people get confused. What if the dog was a "good boy" that never barked at a fly, but the owner left the gate unlatched and it got out and bit you?

In this scenario, we don't care about the dog's history. We care about the owner’s actions.

If an owner fails to use "reasonable care" to restrain their dog, they are being negligent. This is especially true in cities like San Antonio, Houston, or Dallas, where we have strict "leash laws." If a dog is "running at large" in violation of a local ordinance and bites someone, that is often considered negligence per se. Essentially, the fact that they broke the leash law is proof enough that they were negligent.

Piercing the Shield

Think of the "One Bite Rule" as a shield for owners of well-behaved dogs. It’s there to protect people from truly unpredictable accidents. But that shield disappears if:

1. The dog was known to be mean (Strict Liability).

2. The owner was careless (Negligence).

If you walk a 100-pound dog on a piece of sewing thread and it breaks loose to chase a squirrel and bites you, the "One Bite Rule" won't save the owner. They were negligent in how they restrained the animal.

The $100,000 Requirement

Texas also has a "Dangerous Dog" statute. If a dog is officially designated as dangerous by animal control after an attack, the owner is required by law to carry at least $100,000 in liability insurance. Navigating these statutes and finding where that coverage exists is exactly what I do for my clients.

I Am Always a Call Away

Dog bite cases can get "into the weeds" very quickly with insurance exclusions and local ordinances. If you’ve been bitten, don’t take "no" for an answer from an insurance adjuster who claims the owner isn't liable.

Give me a call. We can go over the details of where the dog came from and how it was restrained right over the phone. I’ll help you understand the "why" behind your case so you can focus on your recovery.
