Arizona Pet Travel Rules for RVers

Required Travel Documents

Arizona does not require a Certificate of Veterinary Inspection (CVI) for pet dogs and cats traveling from other U.S. states. However, if you bring livestock, horses, or poultry into Arizona, a CVI and brand inspection certificate are required by the Arizona Department of Agriculture.

It is still wise to carry your pet's vaccination records, especially rabies. Many private campgrounds and RV parks in Arizona require proof of current rabies vaccination at check-in.

If you cross from Mexico into Arizona with a pet, U.S. Customs and Border Protection (CBP) requires a rabies vaccination certificate for dogs. No CVI is required for cats entering from Mexico, but a rabies cert is recommended.

Vaccination Requirements

Arizona state law requires rabies vaccination for dogs. Cats are not legally required to be vaccinated under state law, but many municipalities and parks require it.

Rattlesnake vaccine (from Merial/Elanco) is not a legal requirement but is strongly recommended by Arizona veterinarians for dogs spending time in desert areas. It does not eliminate the need for emergency vet care after a bite but can reduce severity.

RV and Vehicle Rules

Arizona's maximum length for a single-unit motorhome is 40 feet. For a combination vehicle (truck + trailer), the combined maximum is 65 feet.

Width is limited to 102 inches, and height to 14 feet on most roads. Highway 89A through Oak Creek Canyon and portions of SR-188 around Roosevelt Lake have switchbacks and tight turns that challenge longer rigs — plan routes carefully.

The Navajo Nation and Hopi reservation roads are not always subject to the same speed or size regulations as state roads, and some reservation routes have weight limits. Check with tribal authorities before routing through reservation land.

Heat is an extreme hazard in Arizona (May–October temperatures regularly exceed 110°F in the low desert). Never leave pets in a parked vehicle. Arizona law (ARS §13-2910) prohibits leaving an animal confined in a vehicle under conditions that endanger health.

State Park and Campground Pet Policies

Arizona State Parks allow leashed pets in campgrounds and most day-use areas. The standard rule is a leash no longer than 6 feet.

Many Arizona parks prohibit pets on certain trails to protect desert wildlife, especially during sensitive seasons. Saguaro National Park (NPS) prohibits dogs on all trails but allows them on paved roads and in picnic areas.

Grand Canyon National Park allows leashed pets on the South Rim's paved paths and at campgrounds but prohibits them below the rim (no trail access). Grand Canyon's North Rim has similar rules.

Sonoran Desert is home to rattlesnakes, scorpions, Gila monsters, and coyotes — all of which pose risks to off-leash dogs. Keep pets close at all times.

Breed Restrictions and Quarantine Notes

Arizona has no statewide breed-specific legislation. Some municipalities may have local ordinances. Verify with your specific destination city or county.

No quarantine is required for domestic dogs or cats entering from other U.S. states.

Disclaimer: verify current requirements with the Arizona Department of Agriculture (azda.gov) before your trip.
