Flying a dog from Northern Ireland to the United States
USA: Federal rules for pets entering the US mainland. Each state can add its own entry rules.
Conditional: yes, with 1 hard deadline
A dog can enter the United States (Federal rules for pets entering the US mainland) from Northern Ireland without quarantine when every condition is met. It needs an age of at least 6 months on arrival, a CDC Dog Import Form receipt on or before arrival, a microchip a universal scanner can read and a healthy appearance on arrival. If a condition is missed: An animal refused entry after a flight is returned by the airline to the country it left, on the next available flight and at the importer's expense.

Your deadlines, counted back from arrival
1 of these steps is a hard deadline. Changing the date re-dates the plan in your browser; it fetches nothing.
Lead time: 0 days
By 184 days before arrival
Birth
The dog is at least 6 months old on the day it arrives. Timing: at least 6 months before arrival.
Fails if: Done less than 6 months before arrival.
Arrival day
Import formHard deadline
The importer submits a complete CDC Dog Import Form before the dog arrives; it can be filled in on the day of travel. Timing: on or before arrival.
Fails if: Done after arrival.
The receipt is valid for 6 months from when it is issued, so the form is submitted no more than 6 months before the dog arrives. A visit to a high-risk country, or to a different low-risk country, in that time needs a new form. Timing: within 6 months before arrival.
Fails if: Done more than 6 months before arrival.
