Texas Pet Travel Rules for RVers

Required Travel Documents

Texas does not require a Certificate of Veterinary Inspection (CVI) for pet dogs and cats entering from other U.S. states. However, dogs and cats entering from Mexico or other countries must have a valid CVI issued by a licensed veterinarian.

For travel within the U.S., it is still good practice to carry a copy of your pet's rabies vaccination certificate, especially if you plan to stay at campgrounds, visit groomers, or board your pet en route.

Texas does require a CVI for livestock and most birds entering the state. If you travel with horses, goats, or chickens alongside your dogs, consult the Texas Animal Health Commission (TAHC) for current entry requirements.

Vaccination Requirements

Rabies vaccination is required by state law for dogs and cats in Texas (all counties). Proof of a current rabies vaccine is commonly required at campground check-in and any boarding facility.

Texas does not mandate other specific vaccinations for pet travel, but the Texas A&M Veterinary Medical Teaching Hospital and most vets recommend keeping DHPP (dogs) and FVRCP (cats) current before any road trip.

RV and Vehicle Rules

Texas allows single-unit RVs (motorhomes, fifth-wheels) up to 45 feet long on most highways — one of the most generous limits in the country. The maximum combined length for a tow vehicle plus trailer is 65 feet.

Width is capped at 102 inches (8.5 feet) and height at 14 feet on most roads. Texas highways are generally well-suited for large rigs, but watch for low bridges and underpasses on farm-to-market (FM) and ranch-to-market (RM) roads, which often have 13-foot limits.

Texas has no explicit state law requiring pets to be restrained in moving vehicles. That said, an unrestrained animal that distracts the driver or contributes to an accident could support a reckless driving charge under general traffic law.

Cruelty laws prohibit leaving an animal in a vehicle in conditions that are dangerous (excessive heat is a major risk in Texas summers). Texas Penal Code §42.092 makes it a criminal offense.

State Park and Campground Pet Policies

Texas State Parks are exceptionally pet-friendly. The Texas Parks & Wildlife Department (TPWD) allows leashed dogs (6-foot maximum leash) in most developed areas, campgrounds, and many trails.

Pets are not allowed in swimming areas, cabins, or park buildings. Some natural areas and wildlife management areas have seasonal restrictions during bird nesting season.

Pet fees vary by park but are typically $2–$5 per pet per night. The Texas State Parks Pass (annual) does not include pet fees.

Many Texas state parks have water-filling stations and dog-wash areas — Big Bend National Park (federal, but adjacent to state lands) does not allow pets on backcountry trails.

Breed Restrictions and Quarantine Notes

Texas has no statewide breed-specific legislation. Some Texas cities and counties do have BSL — notably certain municipalities in the Dallas-Fort Worth metro area — so check local ordinances at your destination.

There is no domestic quarantine requirement for pet dogs or cats entering Texas from other U.S. states. If entering from Mexico, USDA/APHIS border regulations apply.

Disclaimer: regulations change. Always verify with the Texas Animal Health Commission (tahc.texas.gov) and TPWD before your trip.
