Traveling to Ireland with a dog in 2026 requires strict adherence to the "Pet Travel" rules to avoid quarantine. First, your dog must be microchipped with an ISO-compliant chip. Second, they must have a valid rabies vaccination administered after the microchip was inserted; if it is their first vaccination, you must wait at least 21 days before traveling. Third, you must obtain an EU Pet Passport (if coming from the EU) or an EU Health Certificate (if coming from a non-EU country like the USA) signed by an official government vet. Most importantly, dogs entering Ireland must receive a tapeworm treatment (Echinococcus multilocularis) administered by a vet between 24 and 120 hours (1 to 5 days) before the scheduled arrival time in Ireland. If you are flying, you must use a sanctioned "Clean Agent" for the flight and ensure your airline is approved to carry pets into Dublin, Cork, or Shannon airports.
