Travelling with Pets: A Complete Guide for Every Mode of Transport

Taking your pet along on a trip can be one of the most rewarding experiences of pet ownership — or one of the most stressful. The difference usually comes down to preparation. A well-planned journey with the right documentation, equipment, and anxiety management strategy can be smooth and enjoyable. A last-minute scramble can turn into a nightmare for both you and your animal.

Whether you are driving across the country, flying internationally, catching a train, or boarding a ferry, this guide covers everything you need to know to travel safely and comfortably with your dog or cat. We will also help you recognise when leaving your pet at home with a trusted sitter might actually be the kindest option.

Car Travel with Pets

Car travel is the most common and often the easiest way to travel with a pet. You control the environment, you can stop whenever needed, and there are no size or breed restrictions. But even car travel requires planning and safety measures.

Safety First: Restraints and Crates

An unrestrained pet in a car is a safety hazard — to themselves, to you, and to other passengers. In a sudden stop or collision, an unrestrained dog becomes a projectile. A 25-kilogram dog in a 50 km/h crash exerts the force of a 750-kilogram object. Many countries and states also have laws requiring pets to be restrained in vehicles.

Your options include:

• Crash-tested crate or carrier. The safest option. Place it in the boot (estate/SUV) or behind the front seats, secured with the seatbelt or cargo anchors. Look for crates that have been independently crash-tested — not all crates marketed as "travel safe" have been.
• Dog seatbelt harness. Attaches to the car's seatbelt system and allows some movement while preventing the dog from flying forward. Choose one that clips to the seatbelt buckle (not just the headrest) and is crash-rated.
• Rear barrier or cargo net. Keeps dogs in the boot area of an estate car or SUV. Better than nothing, but does not prevent injury in a serious crash.
• Cat carrier on the seat. Cats should always travel in a secure carrier, belted into the back seat. Never let a cat roam freely in a car — they will end up under the brake pedal.

Managing Motion Sickness

Motion sickness is surprisingly common in dogs, especially puppies. Signs include drooling, lip-licking, yawning, whining, vomiting, and restlessness. If your dog suffers from motion sickness:

• Start with short trips. Gradually increase the duration over several weeks to build tolerance.
• Face forward. Position the crate or harness so your dog faces forward, not sideways.
• Fresh air. Crack a window slightly for airflow, but never enough for the dog to stick their head out.
• Empty stomach. Withhold food for two to three hours before travel, but always provide water.
• Veterinary help. For severe cases, your vet can prescribe anti-nausea medication (maropitant/Cerenia is commonly used for dogs).

Road Trip Essentials

For longer drives, pack:

• Water and a collapsible bowl. Offer water every two hours.
• Waste bags and paper towels. Accidents happen.
• A familiar blanket or toy. Comfort items reduce stress.
• Leash and collar with ID tags. Essential for every rest stop.
• Pet first aid kit. Including tick remover, bandages, antiseptic, and any medications your pet takes.
• Recent photo of your pet. In case they get lost at a rest stop.

Rest Stops

Plan to stop every two to three hours for a bathroom break, a short walk, and water. Never leave your pet in a parked car, even for a few minutes — temperatures inside a car can reach dangerous levels within minutes, even on mild days. If you need to stop somewhere your pet cannot come inside, one person should stay with the car and the pet, with windows open and the engine running for air conditioning if needed.

Flying with Pets

Air travel with pets is more complex and requires more advance planning than any other mode of transport. Airline policies vary widely, and the rules change frequently. Always check directly with your airline well before your travel date.

Cabin vs. Cargo

Most airlines that accept pets offer two options:

In-cabin (under the seat)

• Typically limited to small dogs and cats that fit in an airline-approved carrier under the seat in front of you.
• Maximum carrier dimensions are usually around 43 x 30 x 20 cm, but this varies by airline and aircraft type.
• The pet plus carrier usually cannot exceed 8 to 10 kg.
• You will pay a pet fee, typically 50 to 200 euros per flight segment.
• This is by far the safest and least stressful option for your pet.

Cargo hold (checked pet)

• For larger dogs that cannot fit under a seat.
• The pet travels in a pressurised, temperature-controlled section of the cargo hold.
• Requires an IATA-compliant hard-sided crate with ventilation, water dish, and absorbent lining.
• Higher fees, typically 150 to 400 euros depending on the route and animal size.
• More stressful for the animal, with risks including temperature extremes during loading/unloading, noise, and delays.

Breed Restrictions

Most airlines will not transport brachycephalic (flat-faced) breeds in the cargo hold due to their increased risk of respiratory distress. This includes:

• Dogs: French Bulldogs, English Bulldogs, Pugs, Boston Terriers, Boxers, Pekingese, Shih Tzus, and similar breeds.
• Cats: Persian, Himalayan, Exotic Shorthair, and British Shorthair.

Some airlines also restrict certain breeds during hot or cold months, or ban them entirely. Check with your specific airline.

Airline-Approved Carriers

For cabin travel, your carrier must:

• Be leak-proof and well-ventilated.
• Fit under the seat in front of you.
• Allow the pet to stand, turn around, and lie down comfortably.
• Have a secure closure that the pet cannot open.

For cargo travel, the crate must meet IATA Live Animals Regulations:

• Hard-sided construction (no soft carriers).
• Ventilation on at least three sides.
• "Live Animal" stickers and directional arrows.
• Water dish accessible from outside the crate.
• Absorbent bedding.
• Cable ties on the door (not padlocks — security staff must be able to open it in an emergency).

Preparing Your Pet for a Flight

• Visit the vet. Get a health check and any required certificates within the airline's required timeframe (usually 10 days before travel).
• Familiarise the carrier. Let your pet sleep in and eat in the carrier for several weeks before the flight.
• Exercise before departure. A tired pet is a calmer pet.
• Limit food. Feed a light meal four to six hours before the flight, but provide water until departure.
• Avoid sedation. Most veterinarians and airlines advise against sedating pets for flights, as sedation can affect breathing and thermoregulation at altitude. Natural calming aids (adaptil spray, calming treats) are generally acceptable.
• Attach ID. Your carrier should have a tag with your name, phone number, destination, and your pet's name.

Train Travel with Pets

Train travel with pets varies enormously by country and rail operator. In general, European trains are more pet-friendly than many other regions.

European Rail Policies (General Overview)

• Germany (Deutsche Bahn): Small pets in carriers travel free. Dogs too large for a carrier pay a reduced fare (roughly half the adult fare) and must be leashed and muzzled.
• France (SNCF/TGV): Small pets under 6 kg travel in a carrier for a flat fee (around 7 euros). Larger dogs pay a flat fee (around 50 percent of a second-class ticket) and must be leashed and muzzled.
• Netherlands (NS): Dogs travel free on Dutch trains but must be on a lead. Aggressive breeds may require a muzzle.
• Belgium (SNCB): Small animals in carriers are free. Large dogs require a ticket.
• Spain (Renfe): Pets under 10 kg can travel in carriers on AVE and long-distance trains for a fee. Larger dogs are generally not permitted on high-speed trains.
• Italy (Trenitalia): Small pets in carriers are free. Larger dogs require a ticket, a muzzle, and a lead.
• United Kingdom: Most UK train operators allow dogs for free, without size restrictions. Dogs must be under control and not occupy a seat. Cats and other small animals must be in carriers.
• Australia: Generally, only assistance dogs are allowed on metropolitan trains. Long-distance train policies vary — check with the specific operator.

Tips for Train Travel

• Book in advance. Some operators limit the number of pets per train or carriage.
• Choose off-peak times. Quieter trains are less stressful for your pet and more comfortable for other passengers.
• Bring a mat or blanket. Give your dog a defined spot to lie on.
• Water and treats. Long journeys require hydration and positive reinforcement.
• Toilet considerations. There are no rest stops on trains. Plan accordingly — walk your dog thoroughly before boarding, and have absorbent pads in the carrier for small animals.

Ferry Travel with Pets

Ferries are a popular option for pet owners travelling between the UK and continental Europe, or between mainland Australia and Tasmania. Policies vary by operator, but here are the general patterns:

Standard Ferry Policies

• Car deck kennels. Many ferries provide pet-friendly kennels on the car deck. You visit your pet during the crossing but they cannot come to passenger areas.
• Pet-friendly cabins. Some operators (notably Stena Line, Irish Ferries, and Brittany Ferries) offer pet-friendly cabins where your pet stays with you for the duration of the crossing.
• Vehicle option. On shorter crossings, some operators allow pets to remain in your vehicle on the car deck. This is generally acceptable for short crossings (under two hours) in mild weather but raises welfare concerns on longer routes.
• Outdoor deck access. Some ferries have designated pet exercise areas on deck.

What to Bring

• Carrier or crate. Even if your pet will be in a cabin, bring a carrier for the initial boarding process.
• Water, food, and bowls.
• Waste bags and cleaning supplies.
• Bedding. Familiar bedding helps your pet settle in an unfamiliar environment.
• Medications. If your pet gets motion sick on water, talk to your vet about anti-nausea medication before the crossing.

International Documentation

Crossing international borders with a pet requires documentation. The requirements vary by destination, but here are the most common scenarios:

EU Pet Passport

If you are travelling within the European Union (or from the EU to certain associated countries), your pet needs an EU Pet Passport. This is issued by a licensed veterinarian and contains:

• Microchip number (ISO 11784/11785 compliant).
• Rabies vaccination record. The primary vaccination must be at least 21 days old before travel.
• Veterinary health declaration (for some routes).

Since Brexit, UK pets entering the EU need an Animal Health Certificate (AHC) issued by an Official Veterinarian within 10 days of travel, rather than an EU Pet Passport.

Rabies Vaccination

Rabies vaccination is required for international pet travel almost everywhere. Key points:

• The pet must be microchipped before or on the same day as the rabies vaccination.
• For most destinations, the vaccine must be at least 21 days old.
• For travel to rabies-free countries (Australia, New Zealand, Japan, among others), a rabies titre test and extended waiting period (up to 180 days) may be required.
• Puppies and kittens cannot be vaccinated against rabies until 12 weeks of age in most jurisdictions, which means they cannot travel internationally until at least 15 weeks old.

Travel to Australia and New Zealand

Australia and New Zealand have some of the strictest pet import requirements in the world, designed to protect their rabies-free and pest-free status:

• Rabies titre test with a minimum waiting period (usually 180 days from the blood test).
• Approved country of origin. Not all countries qualify for direct import.
• Internal and external parasite treatment within specific timeframes.
• Import permit from the destination country's agriculture department.
• Mandatory quarantine on arrival (currently 10 days in Australia at the Mickleham quarantine facility).

Start the process at least six to nine months before your intended travel date. Using a licensed pet transport agent is strongly recommended for Australia and New Zealand imports.

USDA Health Certificate (Travel to/from the US)

For travel to or from the United States:

• A USDA-endorsed veterinary health certificate is required within 10 days of travel.
• Rabies vaccination certificate.
• Some states have additional requirements (Hawaii has its own quarantine process).
• The CDC has updated requirements as of 2024 for dogs entering the US, including specific documentation based on the country of origin.

Managing Travel Anxiety

Many pets experience anxiety during travel, especially if they are not accustomed to it. Here is how to help:

Before the Trip

• Gradual desensitisation. Weeks or months before travel, slowly introduce your pet to the carrier, car, or travel environment. Start with short positive experiences and gradually increase duration.
• Positive associations. Feed meals in the carrier. Give treats in the car. Make the travel environment a source of good things.
• Familiar items. A blanket or toy with familiar scents provides comfort in unfamiliar settings.

During Travel

• Stay calm. Pets pick up on your stress. If you are anxious, they will be too.
• Maintain routine. Feed at normal times, walk at normal intervals, and keep bedtime consistent.
• Natural calming aids. Adaptil (for dogs) or Feliway (for cats) spray on bedding, calming treats with L-theanine or tryptophan, or a Thunder Shirt for dogs.
• Music. Classical music or specially designed pet-calming music can reduce anxiety. There are playlists specifically created for this purpose.

When to Talk to Your Vet

If your pet has severe travel anxiety — constant panting, drooling, trembling, destructive behaviour, or refusal to eat — talk to your veterinarian. They may recommend:

• Prescription anti-anxiety medication (trazodone, gabapentin, or alprazolam for dogs; gabapentin for cats). These should be trialled at home before travel to check for side effects.
• A behavioural consultation for long-term desensitisation training.

Note: Heavy sedation is generally not recommended for travel, particularly for flying. Sedated animals cannot regulate their body temperature effectively and are at greater risk of respiratory and cardiovascular complications.

When a Pet Sitter Is the Better Option

Here is the honest truth that no travel guide likes to say: sometimes, leaving your pet at home is the kindest thing you can do.

Consider a Pet Sitter When:

• Your pet has severe anxiety. If travel causes extreme distress, forcing them through it is not kind.
• The journey is long and complex. A 20-hour international flight with two layovers and a quarantine period at the other end is an ordeal for any animal.
• Your pet is elderly or has health conditions. The stress of travel can exacerbate health problems in senior or medically fragile pets.
• Your accommodation is not pet-friendly. Keeping a dog in a small hotel room all day while you attend meetings is not a holiday for anyone.
• The trip is short. For a weekend getaway or a five-day business trip, the logistics of transporting a pet often outweigh the benefits.
• You are travelling to a country with strict quarantine requirements. A 10-day quarantine in a government facility is genuinely unpleasant for most animals.

How to Prepare Your Pet Sitter

If you decide to leave your pet at home, set your sitter up for success:

1. Book early. Good sitters fill up fast, especially during holiday periods. Book through The Pet Sitter well in advance.
2. Meet and greet. Arrange a pre-booking meeting so your pet and the sitter can get acquainted.
3. Write detailed instructions. Feeding schedule, medications, exercise routine, behaviour quirks, emergency vet details, and your contact information.
4. Leave enough supplies. Food, treats, medications, waste bags, and any comfort items.
5. Provide emergency contacts. Your vet's number, a local friend or family member, and your own phone number with international dialling code if you are abroad.
6. Request updates. Ask your sitter to send daily photos or updates via the messaging system on The Pet Sitter. It will put your mind at ease.

Frequently Asked Questions

Can I take my dog on a plane in the cabin?

Yes, most airlines allow small dogs in the cabin if they fit in an approved carrier under the seat in front of you. The combined weight of the pet and carrier typically cannot exceed 8 to 10 kilograms. You will need to book the pet space in advance and pay a fee. Not all airlines accept pets in the cabin, and policies vary — always check directly with your airline.

What documents do I need to travel with my pet internationally?

At minimum, you will need proof of microchipping, a current rabies vaccination certificate, and a veterinary health certificate issued within the required timeframe (usually 10 days before travel). For EU travel, an EU Pet Passport or Animal Health Certificate is required. Some countries also require import permits, titre tests, or parasite treatments. Check the requirements for your specific destination well in advance.

Is it safe to fly my dog in cargo?

Cargo travel is generally safe on reputable airlines that follow IATA Live Animals Regulations, but it is more stressful than cabin travel and carries higher risks. The cargo hold is pressurised and temperature-controlled, but there are risks during loading, unloading, and delays on the tarmac. Brachycephalic breeds face additional respiratory risks. If your dog must fly cargo, choose a direct flight, avoid extreme weather days, and use an IATA-compliant crate with proper labelling.

How do I know if my pet is too stressed to travel?

Signs of severe travel stress include constant panting, excessive drooling, trembling, vomiting, diarrhoea, refusal to eat, destructive behaviour, and attempting to escape the carrier. If your pet shows these signs consistently during practice sessions or short trips, they may not be suited to travel. Consult your veterinarian about anxiety management options, and seriously consider whether a trusted pet sitter might be the better choice.

Final Thoughts

Travelling with a pet requires more planning than travelling alone, but it can be deeply rewarding. The key is preparation: start early, get the documentation sorted, familiarise your pet with the travel environment, and always prioritise their comfort and safety over your convenience.

And remember — there is no shame in deciding that your pet is better off at home. A happy week with a caring sitter is infinitely better than a stressful journey that leaves your pet anxious and exhausted. Whatever you choose, make the decision based on what is best for your animal, not just what is most convenient for you.
