Texas Dog Bite Laws: Liability, Dangerous Dog Rules, and Insurance
What Texas law expects from you as a dog owner — who pays after a bite, how a dog gets designated dangerous, and whether the state requires liability insurance. Every citation links to the official statute.
This page is not legal advice. It summarizes Texas state law as of 2026-07-13. Laws change and cities add their own rules — personally check the official statutes linked below, and talk to a licensed Texas attorney before acting on anything that matters.

Who pays when a dog bites — the Texas rule
Texas has no dog-bite statute. Liability comes from case law, the one-bite rule set out by the Texas Supreme Court in Marshall v. Ranne, 511 S.W.2d 255 (Tex. 1974).
As an owner, this means a bitten person must show you knew, or should have known, your dog had dangerous tendencies beyond normal for its kind, from a prior bite, aggressive behavior, or a warning you already had. Once that's shown, you're strictly liable, and cannot defend yourself by claiming you took every precaution. With no such warning, you can still be sued for ordinary negligence, for example if you let the dog run loose and it hurt someone. The rule does not cover trespassers: strict liability does not apply if someone was on your property unlawfully when bitten.
Texas also has no statewide leash law protecting people from dogs. Leash rules meant to protect people, rather than livestock, are set locally, by cities and counties.
How a dog gets designated dangerous
Under Section 822.041, a dog is legally dangerous if it makes an unprovoked attack outside a secure enclosure that injures someone, or commits an unprovoked act that would make a reasonable person believe an attack is coming. Animal control investigates a reported incident and, if it finds the dog dangerous, notifies the owner in writing (Section 822.0421). You can appeal within 15 days, up to a jury trial in county court (Section 822.0424).
Once designated, you have 30 days to meet four requirements under Section 822.042: register the dog with local animal control, keep it leashed under someone's control or in a secure enclosure at all times, get liability insurance or show financial responsibility of at least $100,000, and follow any added local rules. A secure enclosure must be locked, keep out the public and children, prevent escape, and carry a marking that a dangerous dog lives there. Annual registration under Section 822.043 also needs proof of rabies vaccination and costs $50 a year, plus $25 to transfer on a sale or move.
Miss the 30-day window and you must surrender the dog. A court can order it seized and, if you still haven't complied 11 days later, humanely destroyed, subject to appeal. An attack outside the enclosure is a Class C misdemeanor for the owner; violating the registration, restraint, or insurance rules is also a Class C misdemeanor, rising to Class B on repeat.
Insurance requirements
Texas does not require liability insurance for dog owners generally. The $100,000 requirement above kicks in only once your dog is legally designated dangerous under Section 822.041, where it's mandatory, tied to registration, and backed by the threat of surrender or destruction of the dog.
For every other Texas dog owner, there is no state insurance mandate. Cities or counties can add extra requirements under Section 822.047.
Worth knowing
- Breed bans: Section 822.047 stops a city or county from writing breed-specific rules into its dangerous-dog program. Whether a city could pass a standalone breed-ownership ban outside that program is unresolved here.
- Rabies quarantine applies if your dog is reported or suspected of having rabies or exposing someone to it (Section 826.042). The statute leaves the exact length to state health department rule; secondary sources commonly cite 10 days, unconfirmed against that primary rule.
- A separate felony law, Section 822.005 (Lillian's Law), applies to any dog, not just one already designated dangerous. Criminally neglecting to secure a dog that then seriously injures or kills someone off your property is a third-degree felony, or second-degree if the attack causes death.
Other states
Rules change at the state line — a dog that is fine at home can put you under a different liability standard on vacation. See the full 50-state table.
