Travelling with Your Pet: The Ultimate Guide

Updated March 2026 — By Claire Morin, certified canine educator

Before you travel: preparation essentials

Successful travel with pets begins weeks before departure. A stressed, unprepared animal transforms a holiday into an ordeal for everyone involved. Whether you are taking a two-hour drive or a transatlantic flight, the preparation principles are the same.

Start with a veterinary visit at least two weeks before travel. Ensure vaccinations are up to date, request a health certificate if crossing borders, and discuss any concerns about motion sickness or anxiety. If your pet has never travelled, begin conditioning them to their carrier or car harness in short, positive sessions well in advance. A pet that associates the carrier with treats and calm experiences will handle travel far better than one thrust into an unfamiliar container on departure day.

Ensure your pet's microchip is registered with current contact details including your mobile phone number. Attach an ID tag to the collar with your name, phone number, and destination address. These precautions are simple but could mean the difference between a lost pet and a quick reunion.

Travelling by car

Car travel is the most common and most controllable form of pet transportation. Done well, most dogs enjoy it and most cats tolerate it. Done poorly, it causes lasting travel anxiety.

Safety first

An unrestrained pet in a moving car is a projectile in a collision. A 25 kg dog in a 50 km/h crash generates the same impact force as a 750 kg object. Restraint is not optional — it is a safety imperative for both the pet and every human in the vehicle. Options include:

• Crash-tested crate: The gold standard. Secured in the boot (estate cars) or rear seat. Choose a crate rated to your pet's weight.
• Car harness with seatbelt attachment: Good for dogs that dislike crates. Ensure it is crash-tested (many are not — look for certification).
• Rear barrier: Separates the boot area from the cabin. Less protective than a crate but allows more movement.
• Carrier secured with seatbelt: Best for cats. Place the carrier on the rear seat and thread the seatbelt through the handle.

Comfort during the journey

Plan stops every two hours for dogs to stretch, drink water, and relieve themselves. Never leave a pet in a parked car, even with windows cracked — interior temperatures can reach lethal levels within minutes on a warm day. Keep the car well-ventilated and at a comfortable temperature. A familiar blanket in the crate or carrier provides reassuring scent.

For dogs prone to motion sickness, withhold food for 3 to 4 hours before travel but provide water. Keep rides smooth — avoid sudden braking and sharp turns. Ginger treats designed for dogs can help settle the stomach. For severe cases, consult your vet about anti-nausea medication.

Travelling by train

Train policies vary significantly by country and operator. In general, small pets in carriers travel free or for a small fee in most European countries. Larger dogs typically require a ticket (often 50% of the adult fare) and must be leashed and muzzled in some jurisdictions.

Key tips for train travel: choose off-peak times when carriages are less crowded; book a seat near the door for easy exit; bring a portable water bowl; ensure your dog has relieved themselves before boarding; and carry a towel for wet weather arrivals. Cats should remain in their carrier throughout the journey — the enclosed space provides security in the unfamiliar environment of a moving train.

In France, SNCF allows dogs under 6 kg in a carrier for free, dogs over 6 kg with a half-price ticket and muzzle, and does not accept cats outside carriers. In the UK, most train companies allow dogs free of charge with no size restriction but require them to be on a lead and well-behaved. Research specific operator policies before booking.

Travelling by plane

Air travel is the most stressful form of transport for most pets and should only be chosen when alternatives are impractical. For short to medium distances, driving is almost always the better option for animal welfare.

Cabin travel

Most airlines allow small pets (typically under 8 kg including carrier) in the cabin. The carrier must fit under the seat in front of you, be ventilated, leak-proof, and secure. Book well in advance — airlines limit the number of in-cabin pets per flight. Avoid peak travel periods when flights are fully booked and cabin temperatures fluctuate.

Cargo hold travel

Larger pets must travel in a pressurised, temperature-controlled cargo hold. This is significantly more stressful. Use an IATA-compliant crate with absorbent bedding, attach water and food dishes that can be filled from outside, and label the crate clearly with your contact information and the word "LIVE ANIMAL" on all sides. Avoid flights with connections — direct routes minimise handling and waiting time on the tarmac.

Brachycephalic breeds (Bulldogs, Pugs, Persian cats) face elevated risks during air travel due to compromised respiratory systems. Many airlines ban these breeds from cargo hold transport entirely. Consult your veterinarian before flying with any flat-faced pet.

Finding pet-friendly accommodation

"Pet-friendly" varies enormously. Some hotels genuinely welcome pets with dedicated amenities, while others simply tolerate them for an extra fee. Clarify before booking:

• Is there a size or breed restriction?
• What is the pet fee (per night or flat rate)?
• Are pets allowed in all areas or restricted to certain rooms?
• Is there a garden or nearby green space for dogs?
• Can pets be left unattended in the room?

Holiday rentals (Airbnb, Vrbo) often offer more space and privacy than hotels but check pet policies carefully — some hosts forbid pets entirely or charge substantial cleaning fees. Bring your pet's own bed, bowls, and familiar toys to make any accommodation feel like home.

International travel requirements

Crossing borders with a pet requires paperwork that varies by destination. For travel within the EU, you need:

• An EU pet passport or animal health certificate issued by an authorised veterinarian.
• A valid rabies vaccination (at least 21 days before travel for primary vaccination).
• An ISO-compliant microchip (implanted before the rabies vaccination).

For travel to the UK post-Brexit, requirements include a microchip, rabies vaccination, an animal health certificate issued within 10 days of travel, and tapeworm treatment for dogs (1 to 5 days before entry). For travel to countries outside the EU, requirements vary significantly — some require rabies titre blood tests taken months in advance. Start researching at least 3 months before your intended travel date.

Managing travel anxiety

Some pets are natural travellers; others find it deeply stressful. Signs of travel anxiety include panting, drooling, trembling, whining, vomiting, and inappropriate elimination. Management strategies include:

• Desensitisation: Gradually expose your pet to the travel environment. Start by sitting in the stationary car with the engine off, then with the engine on, then short drives around the block, slowly building duration.
• Positive associations: Pair travel with treats, praise, and calm energy. Make the carrier or car a place where good things happen.
• Pheromone products: Adaptil (dogs) and Feliway (cats) spray on bedding or in the carrier can reduce stress. Evidence is moderate but these products have no side effects.
• Prescription medication: For severe anxiety, your vet can prescribe anti-anxiety medication or mild sedatives. Never use over-the-counter human medications without veterinary guidance.
• Calming music: Studies have shown that classical music and specially designed pet relaxation playlists can reduce heart rate and cortisol levels in stressed dogs.

The essential packing list

Do not leave without these items:

• Pet passport or health certificate (for border crossings)
• Vaccination records and your vet's phone number
• Enough regular food for the entire trip (changing food causes digestive upset)
• Collapsible water bowl and a filled water bottle
• Leash, harness, and ID tag with current phone number
• Poop bags (more than you think you need)
• Familiar blanket or bed
• Any regular medications plus a small first-aid kit
• Recent photo of your pet on your phone
• Carrier or car crate appropriate for the mode of transport
• Treats for positive reinforcement and distraction
• Towel for wet weather and cleanups
