Your four-legged friend is welcome to accompany you on Swiss trains. You will have to buy an additional half-fare ticket for your dog or a 1-day-travelpass for dogs. Your dog may travel with a 2nd class ticket in 1st class with you. Small dogs of up to 30 cm shoulder height in a suitable carrier travel free of charge as hand luggage. However, if the dog is removed from the carrier during the journey, a ticket will be required. Tickets can be obtained online (sbb.ch) or at the ticket counter.
