Yes, you absolutely can fly your dog and cat to Ireland with you! If you are bringing a pet to Ireland from the USA, you need to comply with certain requirements including proof of rabies vaccine connected to your pet's microchip. Additionally for Ireland & UK (but not all EU countries), a required tapeworm treatment.

As of 2026, the rules for flying into Ireland with a dog in the cabin have become significantly more flexible, but they still depend entirely on your point of origin and the airline. If you are flying from within the European Union, many airlines like KLM, Lufthansa, and Air France allow small dogs (usually under 8kg including the carrier) to fly in the cabin to Dublin. However, if you are flying from the United Kingdom, most airlines still prohibit "in-cabin" pets due to UK-specific carrier rules, forcing pets into the hold. For travelers from the United States, Delta and certain other carriers now allow small dogs in the cabin on direct flights to Dublin, provided the dog stays in a TSA-approved carrier under the seat. You must strictly follow the "Entry Requirements" which include a valid EU Pet Passport or an Annex IV Health Certificate, a microchip, a rabies vaccination at least 21 days prior, and a specific tapeworm treatment administered by a vet 24-120 hours before arrival. It is vital to notify the Irish Department of Agriculture (DAFM) at least 24 hours in advance via an online "Advance Notice" form to ensure a smooth inspection upon landing.
