Health Certificates for Horses: Interstate Travel Guide

Aug 1, 2026

Whether you are heading to a horse show, rodeo, training event, trail ride, or relocating your horse to another state, preparing for the trip involves more than loading the trailer. Interstate travel often requires specific documentation, including health certificates for horses, and in many cases a current negative Coggins test. Understanding these requirements before you travel can help you avoid unexpected delays and make your trip go more smoothly.

At Adobe Veterinary Center, our USDA-accredited veterinarians provide health certificates for horses and livestock. In this article, we will focus on what horse owners need to know before interstate travel.

What Is a Health Certificate for Horses?

A health certificate, officially called a Certificate of Veterinary Inspection (CVI), is a document completed by a USDA-accredited veterinarian after examining your horse. The certificate verifies that your horse appears healthy and meets the destination state’s import requirements at the time of the examination.

Health certificates play an important role in helping prevent the spread of contagious diseases between states while promoting the health of the nation’s equine population.

When Does Your Horse Need a Health Certificate?

In most cases, you will need a health certificate whenever your horse travels across state lines. Common reasons include:

  • Horse shows and competitions
  • Rodeos
  • Clinics and educational events
  • Trail riding trips
  • Relocating to another state
  • Transporting a newly purchased horse home from another state

Some facilities or events may also have their own entry requirements in addition to state regulations.

Do You Also Need a Coggins Test?

Many horse owners wonder whether a health certificate and a Coggins test are the same thing. They are not.

A Coggins test is a blood test that detects Equine Infectious Anemia (EIA), a contagious viral disease that affects horses, donkeys, and mules. Many states require a current negative Coggins test before allowing horses to enter.

Depending on where you’re traveling, you may need:

  • A health certificate
  • A current negative Coggins test
  • Additional documentation required by the destination state or event

Because requirements vary, it is always a good idea to verify what is needed before your trip.

Interstate Travel Requirements Can Vary

Every state establishes its own import requirements for horses. If you are traveling from Arizona to neighboring states such as California, Nevada, New Mexico, Utah, or Colorado, the paperwork required may differ depending on your destination.

Requirements can change over time, making it important to verify current regulations before you travel. The Arizona Department of Agriculture Animal Importation Information provides current import requirements and additional guidance for horse owners planning interstate travel.

Plan Before You Travel

Planning ahead gives you time to complete any required examinations, testing, and paperwork before your departure.

Before traveling:

  • Confirm your destination state’s current entry requirements.
  • Verify whether a current negative Coggins test is required.
  • Make sure your horse’s identification and vaccination records are up to date.
  • Schedule your health certificate examination with enough time to complete any required testing and paperwork before you leave.

Planning ahead helps reduce last-minute surprises and allows you to focus on enjoying your trip with your horse.

Keeping copies of your horse’s health certificates can also be beneficial over time. Along with your horse’s other veterinary records, they provide documentation that may be helpful when traveling, relocating, participating in events, or selling your horse.

Frequently Asked Questions

What is the difference between a health certificate and a Coggins test?

How long is a horse health certificate valid?

The validity period depends on your destination state’s regulations. Because requirements vary, it is important to verify them before your trip and schedule your examination accordingly.

Do all states require a health certificate for horses?

Most interstate travel requires a health certificate, but each state establishes its own entry requirements. Some states or events may also require additional documentation, including a current negative Coggins test.

Can Adobe Veterinary Center provide health certificates for livestock?

Yes. Adobe Veterinary Center provides health certificates for both horses and livestock for interstate travel.
