Are dogs allowed on trains? UK rules and guidance

We all know dogs are big lovers of adventure, but are our four-legged friends allowed to embark on their next journey using the UK rail services and, if so, what’s the catch (or should we say ‘fetch’)? Our guide below covers everything you need to know if you're planning on travelling with a canine commuter.

Can you take dogs on trains in the UK?

Yes, you can take your dog on the train in the UK - and they travel for free! Here’s an in-depth breakdown of everything you need to know:

Dogs travel for free and don’t require a ticket.
A maximum of two dogs are allowed per passenger. For any more than two dogs, it’s your responsibility to check with the train operating company as you may be required to pay an additional fee of up to 50% of a full adult fare, though the maximum charge is £5 for a single journey and £10 for a return.
Dogs must be kept on a lead or a secure pet carrier (maximum size of 85 x 60 x 60cm).
Dogs are not allowed on seats.
Dogs must not irritate or disturb other passengers on the journey or you may be asked to leave the train before your destination. Besides guide dogs, train operating companies reserve the right to refuse animals on their services, but this won’t be an issue if they are well-behaved.
Dogs are not allowed in dining and/or restaurant carriages except for guide or assistance dogs.

Are dogs allowed on the Eurostar?

Unlike most UK services, dogs are not allowed on the Eurostar unless they are registered guide or assistance dogs, trained by either Assistance Dogs (UK), The International Guide Dog Federation or Assistance Dogs International. Necessary paperwork will be required for your guide or assistance dog to hop onboard, where they can travel for free if all requirements are met.

Are dogs allowed on sleeper services?

Yes, dogs are allowed on popular UK sleeper services, but the specific rules will vary depending on the provider.

Caledonian Sleeper: Dogs can travel without a ticket in your sleeper cabin, but you are required to pay a £30 cleaning charge for the room.
Night Riviera: At no extra charge, dogs are permitted onboard, though must stay in the guard’s van in a secure pet carrier.

Please note that these rules do not apply to guide and service dogs.

Are other pets like cats allowed on trains?

Yes! You’re allowed to bring up to two small domestic animals (including cats) onboard, but they must be kept in carriers. Essentially, all the rules above for dogs apply - keep them contained and off seats, make sure they are not disturbing other passengers and keep them away from dining cabins. Follow these rules and make sure the animals could fit within an 85 x 60 x 60cm carrier (no horses, unfortunately) and you’ll be all good!

Our tips for travelling with dogs on trains

Ensure your dog is comfortable: Pick a comfortable leash or a travel carrier with plenty of space for them to relax so that their journey is enjoyable too.
Pick off-peak travel times: If possible, travelling at a quieter time could alleviate any potential issues with either your dog or surrounding passengers.
Introduce your dogs to trains gradually: Consider starting with a short trip to gauge their reaction to rail travel. For some, it's second nature, but for others, it can be distressing.
Reward good behaviour: If your dog is doing a great job, let them know! Bring plenty of treats and shower them with love whenever possible.
Bring water: Trains can get quite hot, especially in summer, so drinking water can be an important way to keep your dog cool and hydrated.
Don’t let dogs on escalators or near tracks: Both escalators and tracks are very dangerous for dogs. For the latter, ensure you’re carrying them when heading down.
