The pet health certificate, explained

Quick answer

A pet health certificate, or Certificate of Veterinary Inspection, is a USDA-accredited vet’s statement that your pet was examined and is fit to travel. It is commonly valid for about 10 days, and international trips often need it endorsed by USDA APHIS.

A health certificate is a vet’s statement that your pet was examined and found fit to travel, with the vaccinations to prove it. It is short-lived by design.

What it is

Formally a Certificate of Veterinary Inspection (CVI). It records the animal’s identity, the exam date, the vet’s finding that the animal shows no signs of infectious disease, and the vaccinations, with the rabies details in full.

Who can issue it

A vet accredited by the USDA. Not every vet is, so ask when you book. For international travel the certificate usually then goes to USDA APHIS for endorsement, which adds days.

How long it is valid

Commonly 10 days from the exam for domestic travel; airlines and destinations can use different windows, and some countries count from the endorsement date. It is the shortest-lived document your pet will ever have.

What to bring to the appointment

  • The rabies certificate and the full vaccination history.
  • The microchip number and registration.
  • The airline’s and destination’s requirements, printed, so the vet completes the right form.
  • Any titer results or parasite treatment records the destination requires.
