✈️ Travel entry rules

Required in some cases

Usually not. Dogs over 3 months travelling with their owner need only proof of rabies vaccination; puppies under 3 months, breeding dogs and dogs changing owner need a health certificate and an import permit.

As summarised by the AKC (March 2023) — confirm with the state veterinarian before you travel:

  • CVI generally not required.
  • Dogs over 3 months of age and traveling with their owners from a non-rabies quarantine area require only proof of rabies vaccination.
  • Dogs under 3 months of age, imported for breeding or destined for a change of ownership must have a CVI, a current rabies vaccination (if the dog is old enough to meet vaccination eligibility), and an import permit. Animals from quarantine areas need special permission from the state Department of Livestock.
  • Import permits are required for companion animals originating from rabies or Foot and Mouth Disease quarantine areas.
  • No specific exhibition exception found.
