Hello @nannyyj
Thank you for your inquiry.
Dogs and small gentle animals may be carried in vehicles, provided that they do not endanger or harass persons or other animals. Small dogs with an instep height of up to 30 cm may be carried free of charge as hand luggage in cages, baskets or other suitable containers suitable for animals. In all other cases and if the animals are taken out of the containers, the 2nd class fare for animals is reduced ½.
Animals may be placed on the seats only in suitable containers. As many 2nd class reduced ½ fare tickets are to be paid as seats are occupied. If your dog is too large for under the seat, it may sit in the aisle or leg space. Please note that this does not interfere with other passengers, nor the customer attendants with the passage. You can also find information about traveling with dogs here: sbb.ch/en
Have a nice day. Kind regards ZoeS
