Key takeaways

- Dogs must be on a lead or in a carrier, and kept off seats.
- Assistance dogs are always allowed, free, with no restrictions.
- Staff can refuse a dog if the train is overcrowded or the dog is disruptive.
- Eurostar does not allow pet dogs (assistance dogs excepted).
The Official Rules for Dogs on Trains
The National Rail Conditions of Travel allow up to two dogs (or other small animals) per passenger at no extra cost.
Your dog must be on a lead or in a suitable pet carrier at all times, must not occupy a seat, and must not be a nuisance to other passengers. Train companies can refuse carriage if the service is very crowded or if they judge the animal unsafe, so travelling off-peak is sensible with a nervous dog.
Which Train Companies Allow Dogs?
All National Rail operators follow the same conditions, so Avanti West Coast, LNER, GWR, Southern, and others all accept dogs under the same rules.
London Underground allows dogs on leads (they must be carried on escalators), and most bus companies accept them at the driver's discretion. The big exception is Eurostar, which does not carry pet dogs at all; only registered assistance dogs may travel.
Tips for a Smooth Journey
Book a table seat or sit near the doors where there is floor space for your dog to lie down. Bring water, a collapsible bowl, and something to chew to keep them settled.
Exercise your dog before boarding so they board tired and calm. Avoid peak-hour commuter trains, which are stressful for dogs and where staff are most likely to refuse. For long journeys, check where you can break the trip for a toilet stop.
What About Large or Nervous Dogs?
There is no size limit in the National Rail conditions: large breeds travel under the same rules as small ones. A short lead and a calm spot on the floor work best for big dogs.
If your dog is anxious around crowds, travel off-peak, consider a calming aid recommended by your vet, and keep journeys short while they get used to it. A muzzle is optional on UK trains, though it can reassure fellow passengers with nervous large breeds.
International Travel With Dogs
Eurostar is the awkward one: pet dogs cannot travel on it, full stop. If you are heading to Europe, look at ferry companies instead; many allow dogs, either in the car or in onboard kennels.
Remember that post-Brexit rules require an animal health certificate from your vet for EU travel, plus an up-to-date rabies vaccination. Start the paperwork at least a month before you travel.
