These are the NS conditions classified into three pet types:
- Small pets: may be transported for free in a bag, basket, or on your lap. There are no requirements for the animal's size or the dimensions of the bag, basket, or cage. Small pets are usually cats or small dogs who can travel for free. They are not permitted to take a seat.
- Larger dogs: must have a dog ticket and must always also be kept on a leash.
- Guide dogs (including those in training): travel for free if they can be identified as a guide dog for the blind or other assistance dog.
