No specific state law
Texas has no state law specifically about animals left in parked vehicles. Leaving a pet in a dangerous car can still be prosecuted as animal cruelty, and some cities have their own ordinances — if you see an animal in distress, call 911.
Yes. Texas requires dogs and cats by 4 months of age to be vaccinated against rabies. Boosters follow the vaccine used (usually every 1 or 3 years).
What the law says: Dogs and cats by 4 months of age and at regular intervals thereafter as prescribed by department rule. V. T. C. A., Health & Safety Code § 826.021
Partly. Counties and cities may add rules for dangerous dogs only if they are not specific to one or more breeds. Other breed-based rules are not expressly prohibited, so check your city’s ordinances.
Texas has no dog-bite strict liability statute. Under the “one-bite” rule and negligence law, an injured person usually has to show the owner knew — or should have known — the dog was dangerous, or was careless in controlling it.
Yes. Texas lets a court include pets in a domestic-violence protective order (since 2011) — for example by giving the petitioner care of the animal and ordering the abuser not to harm or take it.
In a protective order in Texas, the court may prohibit a party from removing a pet, companion animal, or assistance animal, as defined by Section 121.002, Human Resources Code, from the possession of a person named in the order.
Texas has no statewide ban on pet stores selling dogs and cats. Some cities and counties have their own bans — check locally before buying from a store, and ask where the puppy came from.
No health certificate is required for dogs and cats entering Texas, but dogs and cats 12 weeks and older must be vaccinated against rabies and travel with the vaccination certificate. Airlines usually require a recent health certificate.
As summarised by the AKC (March 2023) — confirm with the state veterinarian before you travel:
CVI not required.
If coming into the state via airline, owner must comply with any health certificate requirements provided by the airline.
Dogs at least 12 weeks of age must have current rabies vaccination and vaccination certificate issued within the last 12- 36 months, depending on whether it was a 1 or 3-year vaccine.
Texas has no statewide dog licensing requirement — counties and cities set their own. Most require a licence with proof of rabies vaccination, so check with your local animal services or clerk.
Texas has no statewide leash law. State law expressly lets cities and counties adopt leash requirements, and only bars dogs known to attack livestock from running at large.
