Short distance ticket for dogs?

Hello,

I want to buy short distance ticket for me and my dog. What is the procedure for that?

I can add my dog as a passenger but how do I fill the passenger form? Do I say half-fare travelcard? And what do I enter for birthdate?

Thank you and best regards,

Nurp

Please enter your name and date of birth for your dog’s ticket. You can purchase it at half price.

Kind regards
