Service dogs in the US: what they are, which documents count, and what they get you
Airlines ask for a form, and you sign it yourself. This guide walks you through the DOT forms, the airlines, trains, ferries and cruise lines, and the border rules that still apply.
What most people get wrong
The assumption
A service dog needs a card, a registration number or an official certificate.
What the rules say
It doesn’t. The ADA doesn’t require one, and there’s no federal registry, no government ID and no official certification. For flights, DOT rules let airlines ask for a form — and the person who fills it in is you.
What’s inside the guide
11 pages, checked against the carriers’ and regulators’ own pages.
What counts as a service dog
The task rule, psychiatric service dogs, and why only dogs qualify on planes.
The documents that actually exist
The DOT Service Animal Air Transportation Form, the relief attestation for 8+ hour flights, and ADI training certificates.
What the DOT form gives you — and what it doesn’t
Cabin, trains, ferries, cruises and public places, versus advance notice, dogs in training and flights outside US law.
How to get your dog ready
Owner training, accredited programmes, and why certificates bought online don’t help with US airlines.
Carrier tables
Cabin, fee, dogs in training and documents for each airline, train, ferry and cruise line we checked.
The border rule nobody tells you
CDC Dog Import Form, age, microchip and high-risk rabies countries — the same for service dogs as for pets.

Frequently asked questions
No. The ADA doesn’t require one, and there is no federal registry or government ID. For flights, airlines may ask for the DOT Service Animal Air Transportation Form, which you fill in and sign yourself.
