Moving a dog from the USA to Ireland is a meticulous process that requires strict adherence to EU "Pet Travel" regulations to avoid quarantine. First, your dog must be microchipped with an ISO-compliant chip before receiving a Rabies vaccination, which must be administered at least 21 days before arrival. Second, you must have an EU Health Certificate issued by an USDA-accredited veterinarian and then endorsed by the USDA within 10 days of your arrival in Ireland. A critical Ireland-specific requirement is the tapeworm treatment, which must be administered by a vet 24 to 120 hours (1 to 5 days) before your scheduled arrival. Because Ireland is an island and rabies-free, dogs must arrive via approved "Point of Entry" airports (Dublin, Shannon, or Cork) and undergo a pre-booked compliance check by the Department of Agriculture. It is a supportive peer tip to book your flight well in advance, as many airlines only allow pets to fly as "manifest cargo" on transatlantic routes, which can be expensive and requires coordination with a professional pet shipper to ensure all paperwork is perfect.
