About Snout Route and Howard Cloud →

You're a few weeks out from a move when someone asks whether your pet's travel paperwork is ready. A quick search turns up terms like Certificate of Veterinary Inspection, USDA-accredited veterinarian, rabies certificate, and APHIS endorsement. They are related, but they are not interchangeable.

A health certificate is generally based on a veterinary examination and documents the information required for a particular movement. For interstate travel, the receiving state or territory controls the requirements. USDA APHIS specifically says there is no single federal pet-owner rule for interstate movement; a destination may require a health certificate, vaccinations, tests, treatments, or other documentation. USDA APHIS source ↗

The practical rule: do not get a certificate based on a generic timeline. First identify the destination and type of movement, then schedule the veterinary appointment within the window that actually applies.
CVI basics

What a pet health certificate actually is

A CVI is not simply a copy of vaccine records. It is a veterinary travel document completed for an animal movement and can include identification, exam findings, vaccination information, tests, treatments, and statements required by the receiving authority.

CVI vs. rabies certificate

A rabies certificate documents a specific vaccination. A CVI documents a veterinary examination and whatever additional movement information the destination requires. A trip may require one, the other, both, or neither.

Who issues it?

For interstate movement, the destination state's rules determine which veterinarian and form are acceptable. USDA APHIS does not endorse interstate pet certificates. USDA APHIS ↗

How long is it valid?

There is no universal U.S. validity period. Some receiving jurisdictions use longer windows and others shorter ones. The applicable government rule—or an airline's separate rule—controls.

Does the transporter issue it?

No. Veterinary certificates come from qualified veterinarians. A transporter can review known route requirements and flag missing documents, but it does not replace the veterinarian or the government authority.

Interstate ground travel

Do pets need a health certificate to cross state lines?

Sometimes. The receiving state or territory sets its own animal-entry requirements. USDA APHIS says those rules can include health certificates, vaccination updates, diagnostic testing, or treatments. APHIS also notes that it regulates businesses transporting pets on behalf of owners even though state and territorial authorities set pet-entry requirements for the destination. USDA APHIS ↗

  • Check the destination, not just the origin. Our state pet transport requirements guide links to the agency that controls each state's rules.
  • Account for the purpose of movement. Rules may differ for personal pets, animals being sold or adopted, breeder transfers, exhibition, rescue, or other commercial movement.
  • Match the appointment to the required window. A valid exam performed too early can still produce a certificate that is unusable for the trip.
  • Carry supporting records. Depending on the route, that can include rabies documentation, vaccination history, test results, permits, identification, or other records.
  • Recheck shortly before pickup. Temporary disease-control orders can change after a trip is booked.
Airline travel

Airline rules are a separate layer

An airline can impose documentation requirements in addition to government entry rules. That means a pet may satisfy the destination government's requirements but still need another certificate or form to be accepted by a carrier.

The “10-day rule” is not universal

Some cargo programs use a 10-day certificate window. Delta Cargo, for example, currently requires a domestic health certificate signed by a USDA-accredited veterinarian within 10 days of travel. That is a Delta Cargo rule, not a nationwide rule for every airline or every pet trip. Delta Cargo ↗

Crate standards are separate from the certificate

IATA's Live Animals Regulations set widely used air-transport standards for animal containers and handling, while individual airlines may impose additional requirements. Always verify directly with the carrier. IATA ↗

Snout Route provides ground transportation only. Airline information here is included to explain why a certificate that works for one type of trip may not work for another.

U.S.–Canada travel

Canada does not use one blanket health-certificate rule for every pet

Canada's requirements depend on the animal's species, age, purpose of import, country of origin, and—for dogs in some situations—whether the animal is accompanied by its owner. CFIA tells travelers to check the requirements for their exact situation because the rules and timing can differ. CFIA ↗

Dogs going from the U.S. to Canada

USDA APHIS currently states that pet dogs older than 8 months generally do not need a health certificate to enter Canada; proof of current rabies vaccination is the primary document for the usual personal-pet situation. One or two unaccompanied dogs under 8 months require a veterinary examination and health certificate issued within 72 hours of arrival. USDA APHIS Canada guidance ↗

Cats going from the U.S. to Canada

USDA APHIS currently says pet cats do not require a health certificate for Canada; a rabies vaccination certificate is required for cats old enough to be vaccinated, with kittens under 3 months exempt from that rabies requirement. USDA APHIS Canada guidance ↗

Dogs entering the U.S. from Canada

CDC requirements are separate from Canada's rules. For dogs that have been only in dog-rabies-free or low-risk countries during the previous six months, CDC currently requires a CDC Dog Import Form receipt and also applies age, health, and microchip conditions. CDC ↗

Alaska by road

A ground trip to or from Alaska may transit Canada, so both the destination's U.S. requirements and the applicable Canadian transit/entry rules need to be checked for the specific route. CFIA says Canadian import requirements also apply to animals in transit through Canada. CFIA ↗

For route-specific details, use our U.S.–Canada pet border requirements and Alaska requirements pages.

Outside the U.S. and Canada

International travel can require additional certification

For travel from the United States to countries beyond Canada, the destination country sets the requirements. USDA APHIS says most countries require a health certificate and many require that certificate to be issued by a USDA-accredited veterinarian and then endorsed by APHIS. Requirements can also include microchips, vaccinations, tests, treatments, import permits, and country-specific forms. USDA APHIS process overview ↗

We intentionally do not reproduce country-by-country EU, UK, Japan, or other overseas rules here. Those requirements are outside Snout Route's ground-service scope and can change. Use USDA APHIS and the destination country's animal-health authority for current instructions.
Before pickup

How Snout Route handles documentation review

Snout Route reviews the known documentation requirements for the planned route before pickup and flags items the owner should confirm with a veterinarian or the appropriate government authority. That review helps reduce avoidable surprises, but it does not replace veterinary advice or a government determination.

  • We start with the actual route. Origin, destination, transit states or provinces, pet species, age, and purpose of movement can all matter.
  • We check timing. If a certificate is required, the exam needs to fall within the applicable validity window.
  • We review the documents available. We can flag obvious gaps before pickup rather than discovering them at a border or destination.
  • We defer to the controlling authority. When a rule is unclear or unusual, the veterinarian, receiving state, CFIA, CDC, USDA APHIS, or other responsible agency is the final source.
Common questions

Pet health certificate FAQ

Do I need a pet health certificate for domestic travel?

It depends on where the pet is going and how the pet is traveling. For interstate movement, the receiving state or territory sets the animal-entry requirements. Check the destination's current rule rather than assuming every interstate move requires the same certificate.

How long is a pet health certificate valid?

There is no universal validity period. The receiving government or carrier sets the applicable window. Some airline cargo programs use 10 days, while state requirements can differ.

Who can issue a pet health certificate?

The veterinarian must meet the requirements of the authority or carrier accepting the document. For many international trips that require USDA endorsement, the certificate must be issued by a USDA-accredited veterinarian. USDA APHIS ↗

What is the difference between a health certificate and a rabies certificate?

A rabies certificate documents a rabies vaccination. A health certificate or CVI is based on a veterinary examination and may include additional health and movement information required for the trip.

Do dogs need a health certificate to enter Canada from the U.S.?

Not always. For the usual personal-pet situation, dogs older than 8 months generally need proof of current rabies vaccination rather than a health certificate. Younger unaccompanied dogs can have additional health-certificate requirements. Check the current rule for the dog's age and circumstances before travel.
