evidence: Before the referendum on the UK’s membership of the EU, FactCheckNI published a fact check on the claim that pet owners travelling from Northern Ireland to Ireland already required "EU pet passports". We found this claim to be accurate. [...] The UK is a "Part 2 Country". Pet owners in these countries cannot apply for an EU pet passport. Instead, an "EU animal health certificate" (AHC) is required. However, Northern Ireland is an exception, and pet owners will be able to obtain a valid EU pet passport (see below). [...] The Irish Department of Agriculture, Food and the Marine’s (DAFM) criteria for bringing a pet into Ireland from Northern Ireland includes the pet being microchipped, vaccinated for rabies, and accompanied by an EU pet passport or animal health certificate. Pets can travel into Ireland on a valid Northern Ireland pet passport.
