Moving an animal between states is routine. It goes wrong in predictable ways: a certificate that expired on the road, a missing test, an airline that will not load an animal in July, a transporter nobody checked. This guide is the order of operations. Rules differ by state and species, and they change, sometimes overnight during a disease outbreak, so treat it as a map of what to ask and confirm every requirement with the authority that sets it.
Who makes the rules
- The destination state. Each state's animal health official, usually the state veterinarian, sets the entry requirements for animals coming in: which certificate, which tests, which vaccinations, and whether a permit is needed. Where the animal is going matters far more than where it starts.
- USDA APHIS. The federal animal health agency accredits the veterinarians who sign interstate certificates, runs federal disease programs for livestock, and licenses or registers many businesses that move animals commercially. Its website links to every state's import requirements.
- The carrier. Airlines and transport companies add their own rules on top: certificate age, crate specifications, temperature limits, and breed restrictions.
When the three disagree, the strictest rule is the one that applies to you. Moves to or from another country are a different process entirely, run through USDA APHIS and the other country's authorities; this guide covers moves within the United States.
1. Look up the entry requirements
Before you agree on a handoff date, look up the destination state's requirements for the species, on the state veterinarian's website or through the USDA APHIS directory of state import regulations. Write down four things: the certificate required and how long it stays valid, the tests required and how recent they must be, the vaccinations required, and whether an entry permit is needed and who requests it. If anything is unclear, the state veterinarian's office answers these questions every day. Then write the requirements into the listing's message thread, so the seller books the right exam and the right tests the first time.
2. Time the paperwork to the travel date
Most moves need a certificate of veterinary inspection issued by an accredited veterinarian within a set window before travel: 30 days in many states, and 10 days for many airlines. Book the exam so the certificate is still valid on the day the animal crosses the line, with a margin for delays. Our guide to reading a health certificate like a vet covers what should be on it. Then come the records each species needs.
- Dogs and cats. A certificate and a rabies vaccination for animals old enough to receive one. Federal Animal Welfare Act rules require dogs and cats transported commercially to be at least eight weeks old and weaned, and some states set their own floors for sale and entry.
- Horses. A certificate plus a negative Coggins test for equine infectious anemia, usually drawn within 12 months. Several western states also require a brand inspection when a horse changes owners or leaves the state, and some states issue six-month equine passports for horses that travel often.
- Livestock. Official identification such as approved ear tags, and whatever the destination requires for the species: tuberculosis and brucellosis results for cattle in some states, scrapie identification for sheep and goats, and often an entry permit number obtained before the move.
- Reptiles and exotics. Certificate rules vary widely, and some species need a permit to be owned or sold in the destination state at all. Check legality first, paperwork second.
- Birds. A certificate where required, NPIP status for poultry, and attention to temporary movement restrictions during avian influenza outbreaks.
- Aquatics. Some states require a health certificate for live fish, and some want testing for specific diseases, such as koi herpesvirus for koi.
3. Choose how the animal travels
- Driving it yourself. The simplest paperwork: you carry the documents and control the schedule. Plan water, rest stops, and temperature for the whole route, and never leave an animal in a parked vehicle in the heat.
- A ground transporter. Door-to-door vans for small animals, and trailers for horses and livestock with shared or dedicated loads. Long routes use overnight layover barns or kennels.
- Air. In the cabin for small animals that fit under the seat, or as cargo for larger ones. Airlines restrict short-nosed breeds such as bulldogs and pugs, and many refuse animals in cargo during summer heat and winter cold.
- Live-animal shipping. For reptiles and fish, overnight service in insulated, ventilated packaging, through carriers that accept live animals, with the delivery timed so the box is never left on a porch.
Weather, distance, and cost
Temperature decides more transport dates than paperwork does. In summer, ground transport runs early and late in the day, and airlines stop carrying animals as cargo when temperatures at any airport on the route cross their limits. In winter the same rules apply in reverse. Reptiles, birds, and fish are the most sensitive, which is why live-animal shipments are usually held when the forecast is wrong at either end, and why many reptile sellers offer a live-arrival policy. Ask what it covers and what it asks you to do on delivery.
Horses on long hauls need planning of their own. Most professional haulers offer water every few hours, stop overnight at layover barns on long routes, and let the horse lower its head during the trip, because a horse tied short for many hours is at higher risk of shipping fever, a respiratory infection. Ask how your horse will be tied, how often it will be offered water, and where it will rest.
Quotes for ground transport are usually per mile, with a lower rate for a shared load and a higher one for a dedicated trip, plus fuel, tolls, and layovers on long routes. Air is priced by the crate and the route. Compare quotes on the same terms, and remember the cheapest shared load may take days longer while the truck collects other animals.
4. Check the transporter
A transporter holds the animal and its paperwork for hours or days, so check them as carefully as you checked the seller.
- Ask for their USDA registration or license number where federal rules require one, and their USDOT number if they haul horses or livestock across state lines for hire.
- Ask for proof of insurance that covers animals in their care, and read what it excludes.
- Ask how often the animal is checked, fed, and watered, and whether you get updates at stops.
- Get the full quote in writing, including fuel, layovers, and fees, before the animal moves.
- Hire a transporter you found and chose yourself. A shipping company introduced by a seller you have never met is the setup for the scam described in common pet scams.
When the paperwork is wrong
Read every document the day it is issued, not the day of travel. A wrong microchip number, a misspelled consignee, a missing test result, or a date outside the window is easy to fix while the issuing veterinarian's office is open and nearly impossible to fix at a state line on a Sunday. The issuing vet can correct or reissue a certificate; nobody else can. An animal that reaches an inspection station or an airline counter with incomplete papers can be turned back or held until they are complete, at your cost and at the animal's expense.
Keep digital copies of everything on your phone as well as the originals with the animal, and share them with the transporter before pickup so a missing page is found at the start of the trip rather than the end.
5. Travel day
- The originals of every document travel with the animal: the certificate, test results, permits, and registration.
- Scan the microchip at pickup and compare it with the certificate.
- Pack food, water, and something familiar. On long drives, offer water every few hours.
- Keep the seller's and the transporter's messages together, with times.
6. Arrival and handoff
At handoff, check the animal before anything else: the chip, the markings, and its condition after the trip. Settle it somewhere quiet, keep it apart from your other animals for the first days if the species calls for it, and book a visit with your own veterinarian within the first week.
New birds, fish, and livestock are usually kept apart from the animals already at home for a few weeks, so anything they brought with them shows up before it can spread. Ask your veterinarian how long, for the species you are bringing in.
Confirming handoff is what lets the escrow provider release payment to the seller, so check first and confirm second. Our guide to escrow, step by step covers that part.
How transport works on Everybarn
Everybarn does not carry animals or arrange their travel, and no transporter is paid through Everybarn. What we do is keep the paperwork in one place. A seller can add the interstate health certificate, a Coggins test, and other documents to the listing's Papers, where signed-in buyers can open them. We do not confirm them with the clinic or lab that issued them, so read each one against the checks above. Species that need a legality check are screened against the seller's state before a listing can publish. The destination's rules are yours to confirm, because only you know where the animal is going.
