Hawaii, the only rabies-free state
Every dog arriving in Hawaii, even from the rest of the United States, is inspected at the airport. Honolulu requires no permit; Kona, Kahului and Līhuʻe only take a dog for direct airport release if it holds a state Neighbor Island Inspection Permit, and to obtain one, you must book an approved clinic on the island and get the documents to the quarantine station at least 30 days ahead. A dog denied entry at one of these three airports is taken to Honolulu or sent out of the state at its owner's expense, and some airlines may not take part in these direct arrivals.
The 5-Day-or-Less program (US$244) requires two rabies vaccines given at least 30 days apart, a microchip and an OIE-FAVN titer above 0.5 IU/ml, followed by a waiting period before arrival; otherwise, the quarantine lasts 120 days (US$1,080). A dog whose waiting period is over when it lands, and whose original documents reached the office at least 10 days ahead, can be released directly at Honolulu airport (US$185); the others are taken to the state's quarantine station. Dogs coming from Australia, New Zealand, Guam or the British Isles may qualify for an exemption from quarantine.
A foreign-vaccinated dog that has been in a high-risk country cannot enter the United States through Hawaii, which has no CDC-registered facility: it first goes through one of the 8 airports, then flies on to Hawaii.
Even in transit to another state, a dog that lands in Honolulu stays in quarantine for the whole of its stay in Hawaii.
