For a significant number of people planning on moving abroad to work or retire abroad after 50, the question of what to do with a pet is not a minor logistical detail — it is one of the primary factors shaping which countries are realistic destinations and how the transition gets planned. The good news is that moving internationally with a dog or cat is entirely doable for most popular destinations. The less good news is that it requires substantially more planning, documentation, cost, and lead time than most people expect when they first start researching it.
The critical insight that saves a lot of heartache: entry requirements vary enormously by destination country, and some of the most attractive destinations for 50+ expats have requirements that take 3–6 months to fully satisfy. Starting the process early — well before a departure date is set — is not just advisable but genuinely necessary for some destinations.

The Core Requirements Most Countries Share for those Moving Abroad
The foundation of any international pet move is a current rabies vaccination with documentation, a microchip (ISO 15784 standard, implanted before the rabies vaccination in most countries’ requirements), and a health certificate issued by a USDA-accredited veterinarian within a specific window before travel — usually 10 days for most destinations, though some require USDA endorsement of the certificate, which adds time. For destinations in the European Union, the UK, Australia, and New Zealand, the requirements are particularly specific and must be followed in exact sequence — getting vaccinations or documentation out of order can invalidate the entire process and require restarting from scratch.
Australia and New Zealand maintain the strictest entry requirements in the world for pets, including mandatory quarantine periods (10 days in government-approved facilities for Australia, currently) and a preparation protocol that must begin months before entry. These are not insurmountable but require planning that starts at least 4–6 months before departure. Pet owners considering these destinations should contact a professional pet relocation specialist early in the planning process — the requirements are complex enough that professional guidance typically pays for itself in avoided mistakes.
Popular Expat Destinations and What They Require if You’re Moving Abroad
Mexico — one of the most popular destinations for 50+ US expats — has relatively straightforward pet entry requirements: a health certificate from an accredited vet, proof of current rabies and distemper vaccinations, and a declaration form completed at entry. No quarantine is required. The process is manageable as a self-directed project for most people moving with dogs or cats.
Portugal, Spain, and most EU countries require compliance with the EU Pet Passport equivalent — a specific documentation sequence involving rabies vaccination, rabies titer test (to confirm adequate antibody levels), a waiting period of at least 21 days after the titer test shows adequate protection, and a health certificate from a USDA-accredited vet with USDA endorsement. For some EU destinations the sequence must begin 90 days before travel. The process is navigable but requires careful scheduling.
Thailand, Vietnam, and many Southeast Asian countries have relatively permissive entry requirements for pets — health certificates, vaccination records, and sometimes a brief inspection — and no quarantine for properly documented animals. This makes Southeast Asia, already popular for its low cost of living and warm climate, comparatively easier for pet owners than some European destinations.
The Airline Question
How your pet travels is as important as the destination requirements. Small pets (under approximately 20 lbs including carrier) can typically travel in-cabin on many airlines; larger pets must travel as checked baggage or cargo, with more variable safety records and temperature restrictions that can limit travel windows in summer and winter. Some airlines have suspended pet transport programs entirely in recent years, and policies change; verifying current policies directly with the airline — not through a booking intermediary — is essential.
Non-stop flights are strongly preferred for pets, eliminating layover risks and reducing total travel time. Direct routing may influence carrier selection significantly when a pet is involved. Professional pet relocation services — companies that specialize in international animal transport — manage airline booking, documentation verification, customs compliance, and pickup at the destination, and are worth the cost for people moving to complex-requirement destinations or managing large animals.
Setting Realistic Expectations when Moving Abroad
Pets adjust to new environments at different rates, and the adjustment period for a move abroad is real. Dogs in particular can experience anxiety during transition — new smells, new sounds, disrupted routines, new living situations — and patience during the first few weeks is warranted. Most pets adapt fully within 4–8 weeks of arrival. Building familiar routines quickly, maintaining regular feeding and exercise schedules, and giving extra attention during the transition period supports faster adjustment for most animals.
