Vaccinations: What Your Pet Needs Before Flying

Before your pet crosses borders, vaccinations are the first and sometimes the most time-sensitive requirement. Every country has its own regulations, so checking them early is crucial.

Common required vaccinations

While requirements vary, most countries ask for:

• Rabies vaccination (often mandatory)

• Microchip implantation (ISO-standard)

• Distemper, parvovirus, and hepatitis vaccines (dogs)

• FVRCP core vaccines (cats)

Make sure vaccines are up-to-date and supported by original records from your veterinarian.

Rabies titer test (RNATT)

Some destinations, including Japan, Australia, and parts of the EU,  require a rabies antibody test months before travel.
This can significantly impact your timeline, so plan early.

Vet health checks

Most countries also require a recent veterinary health certificate confirming your pet is fit to fly. These are usually valid for 5–10 days depending on the destination.

Documentation: Paperwork Required for Crossing Borders

Similar to the visa process for humans, pets also need official documentation when traveling internationally.

Key documents include:

• International Health Certificate

• Proof of vaccinations

• Microchip certificate

• Rabies titer test results (if required)

• Import permit (mandatory for many countries)

• Pet passport (for some regions like the EU)

Keep multiple printed copies with you in your carry-on,  as well as digital backups.

Country-specific import rules

Some nations have strict biosecurity controls. For example:

• Australia and New Zealand require quarantine.

• The UK prohibits certain breeds and has strict rabies guidelines.

• Singapore requires pre-approved import permits.

Check government websites early to avoid delays or rejections.

Airlines: Understanding Their Pet Travel Policies

Airlines each have their own rules for animals, from weight limits to carrier sizes to approved cabin travel.

How Pets Can Travel Internationally

When flying with a pet, airlines generally offer three transport options. The right choice depends on your pet’s size, breed, and the airline’s specific policies.

1. In-Cabin Travel

Ideal for small cats and dogs, in-cabin travel allows your pet to stay with you throughout the flight. Most airlines set a weight limit and require the carrier to fit under the seat in front of you.
This option offers comfort and peace of mind, especially for anxious pets or short-haul flights.

2. Checked Baggage (Pet in Hold)

Medium-sized pets often travel as checked baggage in a special section of the aircraft’s cargo hold.
Don’t be alarmed, the area is pressurized, temperature-controlled, and designed specifically for animals. Your pet travels on the same flight as you, which helps streamline pickup and reduces stress.

3. Manifest Cargo (Pet Shipping Service)

Large pets, snub-nosed breeds, or animals traveling alone usually fly as manifest cargo. This involves a dedicated pet shipping process, often used for long-haul or international routes.
Although more complex, manifest cargo is often the safest option for big dogs or destinations with strict import regulations.

Choosing the Right Airline for Your Pet

Not all airlines handle pet travel equally, so it’s important to compare their policies before booking.

What to look for:

• Strong reputation for animal safety and care

• Clear and transparent rules about temperatures, seasonal restrictions, and layover handling

• Reasonable and clearly listed pet fees

• Responsive customer service and, when available, pet-tracking or status updates

Airlines known for excellent pet programs:

KLM, Lufthansa, Emirates, and Air Canada are widely recognized for their animal-friendly procedures, trained staff, and well-managed pet travel services.

Pet Relocation Companies: When to Use One 

Relocating a pet can be complicated, especially when dealing with strict vaccination timelines and customs requirements.
A professional pet relocation company can take over the logistics and handle everything for you.

What they typically assist with:

• Booking airline-approved travel routes

• Handling import permits

• Completing veterinary documents

• Arranging customs clearance

• Providing airline-approved carriers

• Coordinating quarantine when necessary

Pet relocation services are very similar to international moving companies described throughout your company’s blogs

Relocately Blogposts offers expertise, compliance support, and stress-free coordination.

Why consider a relocation service?

• Reduces risk of mistakes on official paperwork

• Prevents flight complications or rejected entries

• Offers comfort knowing your pet is handled by experts

If you’re moving to a country with strict animal regulations (Japan, the UK, Australia), a relocation company is often the easiest and safest choice.

Keeping Your Pet Comfortable During the Journey

Moving abroad can be stressful for animals but with the right preparation, you can make the experience as smooth as possible.

Before the Trip

Preparing your pet early will make the journey far less stressful for both of you.

• Introduce the travel crate weeks in advance. Let your pet explore it freely, nap inside, and associate it with comfort rather than confinement.

• Add familiar bedding or an old T-shirt that smells like you. Familiar scents help reduce anxiety during long travel hours.

• Avoid heavy meals right before flying. A light meal several hours earlier reduces nausea and keeps your pet more comfortable.

• Provide plenty of exercise beforehand. A well-exercised pet is calmer, more relaxed, and more likely to rest during the journey.

During Travel

Your pet’s safety and comfort depend on thoughtful preparation and calm energy.

• Attach a water container and freeze it. It will melt slowly during the flight, keeping your pet hydrated without spilling.

• Label the crate clearly. Include “LIVE ANIMAL,” your contact details, and a recent photo of your pet in case identification is needed.

• Skip sedatives. Most airlines ban them because they can affect your pet’s breathing and temperature regulation.

• Stay calm yourself. Animals are extremely sensitive to human emotions, and your calmness can help reassure them.

Upon Arrival

After a long trip, your pet will need gentle care and time to readjust.

• Offer fresh water right away. Travel can be dehydrating, and animals often drink less while in transit.

• Provide reassurance and a quiet space. Let them decompress without noise, crowds, or excessive stimulation.

• Reintroduce food slowly. Their stomach may be sensitive after the journey—small portions are best.

• Give them time to explore at their own pace. New smells, climate, and routines can be overwhelming; patience will help them settle comfortably.

Final Thoughts

Taking your pet abroad is truly an act of love, one that comes with responsibility, preparation, and a great deal of care. While the process can feel overwhelming at first, planning ahead makes all the difference. By staying on top of vaccinations, gathering the right documentation, choosing a pet-friendly airline, and considering support from professional relocation services, you give your furry companion the safest, smoothest journey possible.

Relocating overseas isn’t just a transition for you, it’s a new adventure for your pet, too. With patience, attention, and the right preparation, the experience becomes not only manageable, but meaningful. In the end, you’re not just moving to a new country; you’re bringing a beloved family member along to start this new chapter with you. And that makes the journey all the more special.
